Transcript:
KIRA: Hi, and welcome to our new podcast 'Making Sense of Science', the show that features interviews with leading experts in health and science about the latest developments and the big ethical questions. I'm your host Kira Peikoff, the editor of leaps.org. And today, we're going to talk about the Covid-19 vaccines. I'm honored that my first guest is Dr. Art Caplan of NYU, one of the world's leading bio-ethicists. Art, thanks so much for joining us today.
DR. CAPLAN: Thank you so much for having me.
KIRA: So the big topic right now is the new J&J vaccine, which is likely to be given to millions of Americans in the coming weeks. It only requires one-shot, it can be stored in refrigerators for several months. It has fewer side-effects and most importantly, it is extremely effective at the big things, preventing hospitalizations and deaths. Though not as effective as Pfizer and Moderna in preventing moderate cases, especially potentially in older adults with underlying conditions. So Art, what's your take overall, on how enthusiastic Americans should be about this vaccine?
DR. CAPLAN: I'm usually enthusiastic. The more weapons, the better. This vaccine, while maybe, slightly less efficacious than the Moderna and the Pfizer ones, is easier to make, is easier to ship. It's one-shot. You know, here there's already been problems of getting people to come back in for their second shots. I would say 5... 7% of people don't show up even though you remind them and you nag them, they don't come back. So a one-shot option is great. A one-shot option that's easy to, if you will, brew up in your rural pharmacy without having to have special instructions is great. And I think it's gonna really facilitate herd-immunity, meaning, we'll see millions and millions and millions of doses of the Janssen vaccine out there as an option, I'm gonna say, summer.
KIRA: Great. And to be fair, it's worth mentioning that the J&J vaccine was tested in clinical trials after variants began to circulate, and it's only one-shot instead of two, like the other vaccines, and it gets more effective over time. So is it really fair to directly compare its efficacy to the mRNA vaccines?
DR. CAPLAN: Well, you know, people are gonna do that. And one issue that'll come up ethically is people are gonna say, "Can I choose my vaccine? I want the most efficacious one. I want the name brand that I trust. I don't want the new platform. I like Janssen's 'cause it's an older, more established way to make vaccines or whatever." Who knows what cuckoo-cockamamie reasons they might have. To me, you take what you can get, it'll be great. It's way above what we normally would expect, those 95% success rates are off the charts. Getting something that's 70% effective, it's perfectly wonderful. I wish we had flu shots that were 70% effective.
And the other thing to keep in mind is we're gonna see more mutations, we're gonna see more strains. That's just a reality of viruses. So they'll mutate, more strains will appear, we can't just say, "Oh my goodness. There's a South-African one or the California one or the UK one. We better... I don't know, do something different." We're just gonna have to basically resign ourselves, I think, to boosters. So right now, take the vaccine. I'm almost tempted to say, "Shut up and take the vaccine. Don't worry about choosing."
Just get what you can get. If you live in a rural community and all they have is Janssen, take it. If you're in another country and all they ship to you is Janssen, take it. And then we'll worry about the next round of virus mutations, if you will, when we get to the boosters. I'm more concerned that these things aren't gonna last more than a year or two than I am that they're not gonna pick up every mutation.
KIRA: So on that note, shipping to rural places or low-income countries that lack the ultra-cold freezers that you need for the super effective mRNA vaccines, the Janssen vaccine seems like a really great option, but are we going to encounter a potential conflict of people saying, "Well, there's "poor or rich vaccines," and one is slightly less effective than the other." And so are we gonna disenfranchise people and undermine their actual willingness to take the vaccine?
DR. CAPLAN: Well, it's interesting. I think the first problem is gonna be, "I have vaccine and I don't have any vaccine," between rich and poor countries. Look, the poor countries are screaming to get vaccine supply sent to them. I think, for example, Ghana received recently 600 million doses of AstraZeneca vaccine. It was freed up by South Africa, which decided they didn't wanna use it 'cause they thought there was "a better vaccine" coming. So even among the poorer nations or the developing nations, some vaccines are getting typed as the not-as-good or the less-desirable... We've already started to see it.
But for the most part, the rich countries are gonna try and vaccinate to herd immunity, you can argue about the ethics of whether that's right, before they start sharing. And I think we'll have haves and have-nots, herd immunity produced in the rich countries, Japan, North America, Europe, by the end of the year anyway. And still some countries floundering around saying, "I didn't get anything," and what are you gonna do?
KIRA: And I know you said to people, which is a very memorable quote, "just shut up and take the vaccine, whatever you can get, whatever is available to you now, do it." But inevitably, as you mentioned, some people are going to say, "Well, I just wanna wait to get the best one possible." When will people have a choice in vaccines, do you think?
DR. CAPLAN: I don't think you'll see that till next year. I think we're gonna see distribution according to where the supply chains are that the vaccine manufacturers use. So if I use McKesson and they ship to the Northeast, and that's where my vaccine goes, that's what's available there. If I'm contracted to Walmart and they buy Janssen, that's what you're gonna see at the big box store. I don't think you're really gonna get too much in the way of choice until next year, when then they're gonna say they ship three different kinds of vaccine, and I can offer you one dose or two dose... One of them lasts a year, one of them lasts 18 months. I don't think we're gonna have the informed choice until next year.
KIRA: Okay. And right now the steep demand is outstripping the supply, and there's been a lot of pressure put on the vaccine makers to ramp up as quickly as possible. Of course, they say that they're doing that and the government is pressuring them to do that, but when do you think we'll cross over to the point where vaccine hesitancy is a bigger issue than vaccine demand?
DR. CAPLAN: Yeah. So this is a really interesting issue. I'm glad you asked me this because I think it's got good foresight. The big ethics fight now is scarcity and who goes first, and the ethicists, including me, are having a fine old time arguing about healthcare workers versus policemen versus people who work for UPS versus somebody who's working at the drug store. Who's more important? Why are they more important? Who's essential?
Actually, I think most of that is nonsense, because what we've learned is that you can't do much in the way of micro-allocation, the system strains, and it doesn't work. You've gotta use some pretty broad categories like over 65, still breathing and working, and a kid. The kid will go last, 'cause we don't have the data, everybody else should get in line and the over 65s should probably be first 'cause they're at high risk. We can't do this. We stink at the micro-management of vaccine supply, plus it encourages cheating. So everybody's out there with vaccine hunters, vaccine tourism, bribing, lying, dressing up like a grandmother to get a vaccine. My favorite one was some rich people in Vancouver flew up to the Yukon and pretended to be Inuit aboriginal people to get a vaccine. That will all pass.
We'll have enough vaccine by the summer, more or less, that the issue will then be, "How are we gonna get to herd immunity or at least maximal immunity, knowing that we don't have data on kids?" People under 18, I think are something like 20% of our population. That means the best you could do is 80%. The other population still could be passing the virus, kids here or Europe or wherever. Well, the military refusal rate that I just saw was 30% saying no. I've heard nursing home staff rates, nursing attendants, nursing aids up at 40% to 50% saying no. So these are huge refusal rates, people are nervous about how it works, the vaccine. Some of them are like, "Well Art you take it. If you're still alive in six months, then maybe I'll take it, but I wanna see that it really works and it's safe." And other people say, "We don't wanna be exploited. We don't trust the government, whatever, to offer us these vaccines."
I'm gonna answer that was a long-winded way of saying we're gonna see some mandates, we're gonna see some coercions start to show up in the vaccine supply, because I think, for example, the military. The day one of these license gets... Excuse me, one of these vaccines get licensed, right now they're on an emergency approval, collect data for three or four more months, get the FDA to formally license the thing. I'd say between five minutes and 10 minutes, the military will be mandating. They have no interest in your objection, they have no interest in your choice, they know what the mission is. It's traditionally, we're gonna get you as healthy as we can to fight a war.
The fact that you say, "Gee, I might die." They kind of say, "Yeah, we noticed that, but that's in the military culture. We fight wars and do stuff like that." So they'll be mandating, I think, very rapidly. And I think healthcare workers will. I think most hospitals are gonna say 50% refusal rate among this nursing group? Forget it. We can't risk that. Nursing homes have been devastated by COVID. They're not gonna have aids out there unvaccinated. The only thing holding up the mandates right now is that we don't have full licensure. We have emergency use approvals, and that's good.
But it's a little tough to mandate without full license. The day we get it, three months, four months, we're gonna start to see mandates. And I'll make one more prediction, as long as I'm in a crystal ball mode. It won't be the government at that point that says, you have to be vaccinated. It'll be private business, 'cause they're gonna say, "You know what? Come on my cruise ship, 'cause everybody who works here is vaccinated." "Come on into my bar, everybody who works here is vaccinated." They're gonna start to use it as an advertising marketing lure. "It's safe here. Come on in." So I think they'll say, "If you wanna work on an airline as a flight attendant, you get vaccinated. We have vaccine proof. You can show it on your iPhone, on your whatever, you have a card that you did it." And so I think we'll see many businesses moving to vaccinate so that they can bring their customers back in.
KIRA: So private businesses, that's one thing, because people do not have to patronize those places if they don't wanna get vaccinated. But of course, this is gonna open up a can of worms with schools. Public schools, if they mandate teacher vaccines and you have to send your kid to school and you have to go to work at a school. What happens then?
DR. CAPLAN: Well, schools are gonna be at the end of the line. That's where we have the least data. So I don't think we're gonna see school mandates on kids, maybe not till next year. But we already have school mandates on kids. They were the first group to feel the force of mandates, because it turns out that measles and mumps and whooping cough are easy to get at school, sneezing and coughing on one another. Some states have added flu shots. Many states, California, Maine, New York have actually eliminated exemptions. The only way out for those kids is if they have a health reason. They're not even allowing religious or so-called philosophical or personal choice exemptions. COVID vaccines will just line up right next to those things.
Teachers will demand it, the pressure will be there. We'll have a lot of information by next year on safety. I'm even gonna say people are gonna be less tolerant of non-vaccinators. Now it's sort of like, "Wow. Yeah, I guess." But this time next year, if you haven't vaccinated, people are gonna come to your house and board it up and make you stay inside.
KIRA: Well, given how much we're so dependent on these vaccines to get us back to a regular life, I can understand the sentiment. What is your take on the big controversy right now, just going back towards the present day a little bit more on having kids in schools. Is that something you support before all the teachers have been vaccinated?
DR. CAPLAN: I do, but I have a problem with the definition of a teacher and a school. So by the way, some people that I know, friends of mine have said, "Well, I'm a teacher, I'm a yoga instructor. I'm a teacher, I'm an aerobics instructor. So I should get priority access to vaccination." I don't think that's what we meant by teacher. And here's the difference in schools. I live in Ridgefield, Connecticut. Up the street for me is a very fancy private elementary school. It has endless grounds, open classrooms. If there are eight kids in a class, I'll pass out. It is great. I wish I went to college there. It's a wonderful set up. Do they need to vaccinate everybody? Probably not, they're all sitting six feet apart, everybody in there is gonna mask, they have huge auditoriums. They never have to come in contact.
I've been in some other schools in the Bronx. No ventilation, no plumbing, 35 kids in a class, the teacher's 65. And you sort of think, "Boy, I'd wanna have vaccinate everybody in sight in this place because unless we re-haul the buildings and downsize the class size, people are gonna get sick in here."
They probably were getting sick anyway before COVID, but now COVID makes it worse. They're probably getting the flu or colds at nine times the rate that they were in Ridgefield, Connecticut. So my point is this, high school kids doing certain things, they can come in on a mixed schedule three days a week, two days a week, do their thing, they know how to mask. Am I worried about vaccinating there? Not too much. Elementary school kids need psychosocial development, need to learn social skills, sometimes going to schools that aren't that wonderful. Yeah, let's vaccinate them. So even though I was complaining a bit about micro-management and trying to parse out, here I think you need to do it. I think you're probably gonna say college, I don't know that you have to vaccinate there. High schools, 50/50. Elementary school, let's do them first.
KIRA: Got it. And one more question on kids before I wanna move on, there's been talk about whether it's necessary before kids are allowed to get this vaccine to have the FDA go to full approval with the full bulk of data necessary for that versus just an emergency authorization for the general population, given that kids are at so much lower risk than adults. But then of course, it'll take a lot more time, I imagine, to get the kids the vaccines. What's your take on that?
DR. CAPLAN: We historically have demanded higher levels of evidence to do anything with a kid, and I think that's gonna hold true here too. I don't think you're gonna see emergency-use authorization for people under 18. Maybe they'd cut it and say, "We'll do it 12-18," but just looking at the history of drug development, vaccine development, people are really leery of taking risks with kids and appropriately so. Kids can't even make their own decision. I can decide if I wanna take an emergency-use vaccine, if I think it's too iffy I don't take it right now. So up to me to weigh the risk-benefit. I don't think so. I think you'll see licensing required before we really get it, at least 12 and under. Let's put it there. And I'm not worried about the safety or efficacy of these things in kids. I think there's no reason, given the biological mechanisms, to think they're gonna be any different. But it's gonna be pretty tough pre-licensure to impose anything.
KIRA: And when do you think that licensure for kids under 12 could come?
DR. CAPLAN: Well, two groups of people are now being studied, pregnant women, the studies just launched. They'll probably be done sufficiently by the end of the year. Kids for full licensure, spring next year.
KIRA: Okay. And because this is a big question for a lot of women that I know and women in general who are pregnant, what would you say to them now, where we don't have the data yet on the safety, but they have to decide and they can't wait six or nine more months?
DR. CAPLAN: Vaccinate yesterday. Literally, I think the COVID virus is too dangerous, I think it's dangerous to the mom, I think it's dangerous to the fetus. It is an unknown, but boy, I would bet on the vaccine more than I would taking my chances with the virus.
KIRA: Got it. So let's pivot a little bit and talk about some of the big open questions around the vaccines that we're starting to get some early evidence about. For one thing, do they prevent transmission and not just symptomatic disease. And I think it's worth pointing out for our audience here that there is a big difference between preventing symptoms and preventing infections, as lots of asymptomatic people know. And we have a lot of new real-world evidence from Israel, from Scotland, reporting that even asymptomatic infections are greatly reduced by the Pfizer vaccine, for example. What is your take on how this new data is going to change guidance around post-vaccination behaviors?
DR. CAPLAN: Yeah. What do we got in the podcast? Seven or eight hours to go? That's a tough one. It's complicated. But trying to over-simplify a little bit. So there is a difference, and this has gotten confusing, I fear. Some vaccines prevent you from getting infected at all. It looks like the Pfizer and the Moderna fall into that category. That's great, 'cause no matter what else, it probably means you're gonna reduce transmission, 'cause if you can't be infected, I don't know how you're gonna give it to somebody else. So I'll bet that that's a transmission reduction. Looks like Johnson & Johnson, unclear. Seems to prevent bad symptoms and death but not moderate disease, and it isn't clear that it stops you from getting infected. So that may become an issue in terms of how we strategically approach when we have enough vaccine of the different types. We may wanna say, "Look, in some environments, we've gotta control spread... Nursing home. We wanna see the Moderna there. We wanna see the Pfizer there."
In other situations, we just wanna make sure you're not dead, let's get the Janssen thing out there. And that'll be great. I'll tell you... I'll give you an example from my own current existence. So I've been pretty cautious... As I said, I live in Ridgefield, Connecticut. I have a house, pretty roomy, but I haven't left it very often. I'm willing to take the chance to go shopping. I'll confess I'm even willing to take the chance wearing a mask to go to the drug store and I've had a hair-cut or two. So I've been not hyper-cautious, but cautious. I don't invite people over that I don't know where they've been, so to speak. But now I'm vaccinated, and my wife is fully vaccinated. And the other night for the first time, we went out to an indoor restaurant. Probably haven't done that in 10 months... No, I don't know, six months. But a long time...
KIRA: I hope you really enjoyed that first meal out, 'cause that's something that I dream about. Boy, where am I gonna go and what am I gonna order?
DR. CAPLAN: Yeah. We went to the fanciest restaurant in town, as a matter of fact, and they were social distancing and everybody was masked and the wait staff. But I figure, good enough for me. If the thing isn't gonna kill me, if I was just told I was gonna have a risk of being sick for three days or something, that's good enough for me. I don't wanna infect somebody else. So I'll still mask and do that, I'm not sure. But I'm absolutely ready to say, and in fact, I've scheduled two trips. We're gonna take a trip to Florida, we're gonna take a trip to North Carolina in March and April. I'm figuring even then, things will be better. But everybody's gonna have choices like that to make. It'll be really interesting. If I'm Tony Fauci or one of our big public health guys, I don't want anybody going anywhere, I'm risk-averse, until maybe 2027. I think it'll be controlled and eliminated... We'll have lots of data and everything will be great. I'm a little bit more, shall we say, individual choice-oriented, making individual risk things, like I said. As long as I'm responsible to others.
I don't wanna make anybody else sick, but if I am ready to take the chance of just being sick for a few days, and I believe the vaccines available will keep me out of the hospital and keep me out of the Morticians building. Okay, I'm ready to do it. So each one of us is gonna have to make a value decision, this is what I find interesting, about what's normal. It isn't science. It isn't medicine. It's ethics. You're gonna have to decide how much risk do you wanna take. Do you wanna be a jerk to your neighbor, if you could still have a teeny chance of infecting them? Am I willing to live in a world where COVID is around but it's kinda rare? I know kids are still transmitting, but it's not really a huge risk. That's the kind of value choice that each of us will be faced with.
KIRA: I really appreciate your emphasis on individual choice and values here and letting... Basically allowing people to make those judgments based on their circumstances for themselves. If you're not deathly afraid of getting a mild cold-type illness, then I can understand why you wanna fly or go to a restaurant, and other people might not be comfortable with any risk at all, and they're perfectly welcome to stay home.
DR. CAPLAN: Or they may say, "I'm 80, I have nine chronic diseases. A mild illness still freaks me out." Okay, I get that. I'm perfectly respectful of that. It's interesting. I think we've been used to public health messaging, and people have this attitude that at some point, Fauci or the head of the CDC, somebody's gonna show up on TV and say, "All clear, everything's over, back to normal, we've declared victory over the enemy. It's armistice day." Whatever. It isn't gonna work like that is my prediction. It's gonna be a slow creep, different people deciding, "I'm safe enough, I'm wandering out." Other people say, "No, no, not ready." Or somebody saying, "I'm pregnant. I'm staying in. I don't care what's going on. I'm not gonna take that risk." I think people will be surprised that there isn't going to be a national day of resolution or something. [chuckle]
KIRA: Right. It's more about these individual behaviors and over time, letting people decide what to do. So for example, if you had grandkids and they were not vaccinated, but you are, would you hug them, would you get close to them, how would you behave and how do you think they should behave around you?
DR. CAPLAN: So I'd be still nervous about them transmitting, but I'm also a very strong believer in my vaccine. So yes, I would hug them, and yes, I would have them come to visit. And that's probably gonna happen actually fairly soon. But their parents aren't vaccinated yet. And so I'm still nervous that maybe better not to do a lot of social mingling right now. But yeah, people have said to me, "My grandmom is 94. I don't know how long she's gonna be here. You think if I'm vaccinated it's okay to pay a visit." I'm gonna start to say, "Yeah, I get that."
KIRA: And I think one thing that's lost in these discussions of safety is also the aspect of benefits to human life and why we even live in the first place. We don't live lives of complete safety. We drive, we fly, we do things that are risky, but we take those risks, because it's worth it. So I think that should be part of the discussion overall, not just safety, period.
DR. CAPLAN: And not just saving lives. So ski slopes, there are a lot of orthopedic clinics at the bottom of big ski slopes, and sending a message like, "You can break bones here." But people say, "I wanna do it, I enjoy it." Okay, I'm not sure all the time that we should factor all of that into our pooled insurance plan, but that's a fight for another day. Nonetheless, I would... You know something, I would pay for it 'cause I like to encourage people to enjoy themselves. So I have my bad habits, they have their bad habits. I think it's sort of a wash in a certain way. But more to your point, I think if you look out there and say, there are some areas where we don't let you choose. You must put your kid in a car seat. A kid can't make a decision, the thing is very effective, really saves their lives, they should have a life ahead of them, and we're gonna force it. And I'm all for that.
In other instances, I might go into the restaurant. I think it's part of the general, "Am I gonna drive a car, am I gonna cross a busy street... " As you said, there are many things I have to do where I have to think about the risk-benefit. I may make a lousy calculation and underestimate what it means to get in my car and drive in terms of risk relative to getting hit by lightening or some other risks, but that's a little bit more for me.
KIRA: So that's a really thought-provoking conversation, but I wanna switch for a minute to another question mark around the vaccines besides transmission, is the long-term studies of their effects on the immune system. And one thing that I've noticed some experts are concerned about is the fact that a lot of the people in the placebo groups have dropped out of the trials and gotten the vaccine because ethically you can't withhold the vaccinations from these volunteers, but at the same time, that could be hurting our ability to compare the vaccine's long-term effects against people who haven't had the vaccine for a long time. So how significant is this issue in your mind?
DR. CAPLAN: Big. Some people actually proposed that we not let them drop out, we not tell the subjects in these big trials of vaccines if they were in the placebo group. Can't do that. It's clearly unethical... Achieved consensus on that decades ago, with various studies where the researcher said, "We don't have to tell the subjects that there's a treatment." Tuskegee did that, for example, the horrible study in the early, late '60s, early '70s, where they didn't tell people there was a cure and kept the study going of venereal disease, but there have been many others since. We already know you gotta give them the option. Some people may stay in anyway, but not enough to allow the study to really have integrity. So I think current studies are likely to fall apart and we won't get answers in the way we're used to with randomized trials to the long-term effects or even to the how long does it last question.
We need to build a system that can follow people. We can't rely on them being in an observed clinical trial. We have to start to say, "You register, we're gonna check on you every year to see how you're doing." That's gotta be done. And one other provocative idea, I pushed it long ago, challenge studies. Deliberately infect a small group of people, hopefully healthy people that choose to do it with mild COVID and then see what the vaccine does in them and then get an answer faster if you study them over time, they volunteered knowingly to get exposed this way. I think you're gonna see some challenge studies done particularly to compare vaccines. There are still more vaccines coming, maybe some of them will last longer, cheaper, safer, I don't know. The only way you're gonna study the next round of vaccines is in a challenge study. You're never getting anybody to sign up to be in a placebo control randomized trial.
KIRA: So that was actually my next question, that the UK just approved the first ever challenge study to infect the volunteers on purpose with the virus. Now, the UK has often been much more progressive in doing medical research than the US. Do you think the US will ever get to that point or are we just gonna rely on other countries to do that for us?
DR. CAPLAN: I think we won't get there. We're so conservative, so litigation conscious. People are freaked out that if somebody got sick and died in a challenge study, it would bankrupt the sponsor. I think the UK is on the right path, but I don't really think we're gonna follow.
KIRA: Okay, well, I hope that they can do the work that we really need. And I'm grateful that there are other countries that are more permissive of risk-taking and doing the controversial studies that are required.
DR. CAPLAN: Ironically, if you don't do the challenge studies, the only other way you're gonna get to do big-scale randomized placebo trials is in the poorest countries that can't get anything. And that makes it an awful lot like exploitation, taking advantage, as opposed to choice. But that's where you'd go, you'd say, "Oh, I got this new vaccine, I'll test it out in Sierra Leone and they don't have anything anyway. So better that half of them get the vaccine than not." And I still think the challenge study makes more ethic sense.
KIRA: Yeah, absolutely. That would really be a shame to be put in that position instead of just allowing people to decide. We let people sign up for the army where they might die. What's the ethical difference with signing up for a potentially dangerous study, but if you're young and healthy, the risk is low?
DR. CAPLAN: By the way, the risk from COVID to say, 18 to 35-year-olds, who's who you'd be looking at, is about the same as donating a kidney, which we also allow all the time.
KIRA: Right, right. Great point. Before we finish up here, I just wanna quickly touch on, of course, the big elephant in the room, which we all have to deal with, unfortunately, which is the variants. So I wanna talk about where we stand. I've heard some vaccine experts recently say, like Paul Offit, for example, has said he doesn't expect a fourth surge due to this, but others are more cautious and take the flip side saying, "This is the calm before the storm. We're about to see another huge explosion." California has recently reported a new strain as accounts for maybe potentially 50% of cases now, and it could be 90% by the end of March. But we're seeing such big declines in the numbers in hospitalizations, in cases. So what should people make of these conflicting messages?
DR. CAPLAN: There's an attitude in medicine that many doctors take toward things like incipient or new prostate cancer, sometimes toward breast cancer, or at least lumps. It's called watchful waiting. You pay attention. You watch what's going on. But you don't do anything right away. I would still get vaccinated, I would still take what I could get. I still believe that it's likely that these vaccines are gonna provide some protection, if not against infection, then at least against the worst symptoms and the worst chances of dying because they're really gonna boost up the basic immune system, which should be able to start to fight against viruses.
That said, could we wind up with some virulent new strain that evades the current vaccine platforms? Yes. Is it likely? I don't think so. But what it does mean is get ready to get boosters because the response to new strains that have been a result of viral mutations is you gotta adjust your vaccine. That's what we'll do. I hope it doesn't send us back into quarantine and isolation and distancing and all the rest of it as our only control. I'm hoping that the manufacturers can roll out boosters more quickly than the first round of vaccines.
KIRA: And the FDA has just said that the vaccine developers will not need to start over with new clinical trials to these boosters. So that will greatly expedite the process. And do you think that's the right call?
DR. CAPLAN: Yes, absolutely. You're not changing the fundamental nature of the vaccine platform, you're just tweaking, if you will, which chemistry responds to the virus. So yeah, I do.
KIRA: And one question then that necessarily everyone is gonna wonder is, "Well, if I got the J&J vaccine, can I get an mRNA booster?" Can you mix and match? Is that gonna work for your immune system?
DR. CAPLAN: Yeah. We don't have any idea. And I wouldn't do that right away. I know some countries are thinking about that to get more, if you will, use out of a limited supply. I'd say wait three months and do it the right way, where the data is in evidence. I'm not worried about people getting a second shot of something different and dropping dead. I'm just worried that it won't work. [chuckle] So I'm not a fan of mix and match. You can do it in some studies, by the way. You could do it in some challenge studies and get a faster answer than you would having to try and do this in 30,000 people over a year. But no, I don't think that's a good way to go. And I'm not a big fan of one-shot strategies either. I think, what we know is that the second shot really kicks your immune system into high gear and that's what you want for real protection. So I know why people say it but I wouldn't advocate for it.
KIRA: Right. And for my last question. One of our big themes this year that we'll be following all throughout the year at leaps.org is our progress towards an eventual return to life and return to normalcy. So I have to ask that question to you. Given everything that you know and that we've discussed today, when do you think our lives and society will start to look normal again, with schools, and restaurants, and businesses open, people are flying and gathering without fear, traveling, etcetera?
DR. CAPLAN: I think you're gonna see a lot of that this summer. There's gonna be enough vaccine out there, even if the epidemiologists aren't 100% happy. As I said, I think a lot of people are gonna say, "I'm happy enough, good enough for me. I'm going to sports and I'm flying, and I'm taking a vacation." And we'll be outside again. Remember we had the ability to eat outdoors and congregate less when the weather's better around the whole country, and I think that will open up Europe and the US in addition. What I'm worried about is if we had to go back in the fall to a more controlled environment, either 'cause a new strain appeared, or just because things weren't as efficacious as we hoped they'd be. But I think summer is gonna be good this year.
KIRA: Well, I hope you're right. I hope your crystal ball is working today. [chuckle]
DR. CAPLAN: [chuckle] And if it's not working right, email Kira. Don't talk to me.
KIRA: Yeah, I cannot be held liable for this. Thank you Art for a fascinating discussion. And thanks to everyone for listening.

Story by Big Think
We live in strange times, when the technology we depend on the most is also that which we fear the most. We celebrate cutting-edge achievements even as we recoil in fear at how they could be used to hurt us. From genetic engineering and AI to nuclear technology and nanobots, the list of awe-inspiring, fast-developing technologies is long.
However, this fear of the machine is not as new as it may seem. Technology has a longstanding alliance with power and the state. The dark side of human history can be told as a series of wars whose victors are often those with the most advanced technology. (There are exceptions, of course.) Science, and its technological offspring, follows the money.
This fear of the machine seems to be misplaced. The machine has no intent: only its maker does. The fear of the machine is, in essence, the fear we have of each other — of what we are capable of doing to one another.
How AI changes things
Sure, you would reply, but AI changes everything. With artificial intelligence, the machine itself will develop some sort of autonomy, however ill-defined. It will have a will of its own. And this will, if it reflects anything that seems human, will not be benevolent. With AI, the claim goes, the machine will somehow know what it must do to get rid of us. It will threaten us as a species.
Well, this fear is also not new. Mary Shelley wrote Frankenstein in 1818 to warn us of what science could do if it served the wrong calling. In the case of her novel, Dr. Frankenstein’s call was to win the battle against death — to reverse the course of nature. Granted, any cure of an illness interferes with the normal workings of nature, yet we are justly proud of having developed cures for our ailments, prolonging life and increasing its quality. Science can achieve nothing more noble. What messes things up is when the pursuit of good is confused with that of power. In this distorted scale, the more powerful the better. The ultimate goal is to be as powerful as gods — masters of time, of life and death.
Should countries create a World Mind Organization that controls the technologies that develop AI?
Back to AI, there is no doubt the technology will help us tremendously. We will have better medical diagnostics, better traffic control, better bridge designs, and better pedagogical animations to teach in the classroom and virtually. But we will also have better winnings in the stock market, better war strategies, and better soldiers and remote ways of killing. This grants real power to those who control the best technologies. It increases the take of the winners of wars — those fought with weapons, and those fought with money.
A story as old as civilization
The question is how to move forward. This is where things get interesting and complicated. We hear over and over again that there is an urgent need for safeguards, for controls and legislation to deal with the AI revolution. Great. But if these machines are essentially functioning in a semi-black box of self-teaching neural nets, how exactly are we going to make safeguards that are sure to remain effective? How are we to ensure that the AI, with its unlimited ability to gather data, will not come up with new ways to bypass our safeguards, the same way that people break into safes?
The second question is that of global control. As I wrote before, overseeing new technology is complex. Should countries create a World Mind Organization that controls the technologies that develop AI? If so, how do we organize this planet-wide governing board? Who should be a part of its governing structure? What mechanisms will ensure that governments and private companies do not secretly break the rules, especially when to do so would put the most advanced weapons in the hands of the rule breakers? They will need those, after all, if other actors break the rules as well.
As before, the countries with the best scientists and engineers will have a great advantage. A new international détente will emerge in the molds of the nuclear détente of the Cold War. Again, we will fear destructive technology falling into the wrong hands. This can happen easily. AI machines will not need to be built at an industrial scale, as nuclear capabilities were, and AI-based terrorism will be a force to reckon with.
So here we are, afraid of our own technology all over again.
What is missing from this picture? It continues to illustrate the same destructive pattern of greed and power that has defined so much of our civilization. The failure it shows is moral, and only we can change it. We define civilization by the accumulation of wealth, and this worldview is killing us. The project of civilization we invented has become self-cannibalizing. As long as we do not see this, and we keep on following the same route we have trodden for the past 10,000 years, it will be very hard to legislate the technology to come and to ensure such legislation is followed. Unless, of course, AI helps us become better humans, perhaps by teaching us how stupid we have been for so long. This sounds far-fetched, given who this AI will be serving. But one can always hope.
Interview with Jamie Metzl: We need a global OS upgrade
In this Q&A, leading technology and healthcare futurist Jamie Metzl discusses a range of topics and trend lines that will unfold over the next several decades: whether a version of Moore's Law applies to genetic technologies, the ethics of genetic engineering, the dangers of gene hacking, the end of sex, and much more.
Metzl is a member of the WHO expert advisory committee on human genome editing and the bestselling author of Hacking Darwin.
The conversation was lightly edited by Leaps.org for style and length.
In Hacking Darwin, you describe how we may modify the human body with CRISPR technologies, initially to obtain unsurpassed sports performance and then to enhance other human characteristics. What would such power over human biology mean for the future of our civilization?
After nearly four billion years of evolution, our one species suddenly has the increasing ability to read, write, and hack the code of life. This will have massive implications across the board, including in human health and reproduction, plant and animal agriculture, energy and advanced materials, and data storage and computing, just to name a few. My book Hacking Darwin: Genetic Engineering and the Future of Humanity primarly explored how we are currently deploying and will increasingly use our capabilities to transform human life in novel ways. My next book, The Great Biohack: Recasting Life in an Age of Revolutionary Technology, coming out in May 2024, will examine the broader implications for all of life on Earth.
We humans will, over time, use these technologies on ourselves to solve problems and eventually to enhance our capabilities. We need to be extremely conservative, cautious, and careful in doing so, but doing so will almost certainly be part of our future as a species.
In electronics, Moore's law is an established theory that computing power doubles every 18 months. Is there any parallel to be drawn with genetic technologies?
The increase in speed and decrease in costs of genome sequencing have progressed far faster than Moore’s law. It took thirteen years and cost about a billion dollars to sequence the first human genome. Today it takes just a few hours and can cost as little as a hundred dollars to do a far better job. In 2012, Jennifer Doudna and Emmanuel Charpentier published the basic science paper outlining the CRISPR-cas9 genome editing tool that would eventually win them the Nobel prize. Only six years later, the first CRISPR babies were born in China. If it feels like technology is moving ever-faster, that’s because it is.
Let's turn to the topic of aging. Do you think that the field of genetics will advance fast enough to eventually increase maximal lifespan for a child born this year? How about for a person who is currently age 50?
The science of aging is definitely real, but that doesn’t mean we will live forever. Aging is a biological process subject to human manipulation. Decades of animal research shows that. This does not mean we will live forever, but it does me we will be able to do more to expand our healthspans, the period of our lives where we are able to live most vigorously.
The first thing we need to do is make sure everyone on earth has access to the resources necessary to live up to their potential. I live in New York City, and I can take a ten minute subway ride to a neighborhood where the average lifespan is over a decade shorter than in mine. This is true within societies and between countries as well. Secondly, we all can live more like people in the Blue Zones, parts of the world where people live longer, on average, than the rest of us. They get regular exercise, eat healthy foods, have strong social connections, etc. Finally, we will all benefit, over time, from more scientific interventions to extend our healthspan. This may include small molecule drugs like metformin, rapamycin, and NAD+ boosters, blood serum infusions, and many other things.
Science fiction has depicted a future where we will never get sick again, stay young longer or become immortal. Assuming that any of this is remotely possible, should we be afraid of such changes, even if they seem positive in some regards, because we can’t understand the full implications at this point?
Not all of these promises will be realized in full, but we will use these technologies to help us live healthier, longer lives. We will never become immortal becasue nothing lasts forever. We will always get sick, even if the balance of diseases we face shifts over time, as it has always done. It is healthy, and absolutely necessary, that we feel both hope and fear about this future. If we only feel hope, we will blind ourselves to the very real potential downsides. If we only feel fear, we will deny ourselves the very meaningful benefits these technologies have the potential to provide.
A fascinating chapter in Hacking Darwin is entitled The End of Sex. And you see that as a good thing?
We humans will always be a sexually reproducing species, it’s just that we’ll reproduce increasingly less through the physical act of sex. We’re already seeing this with IVF. As the benefits of technology assisted reproduction increase relative to reproduction through the act of sex, many people will come to see assisted reproduction as a better way to reduce risk and, over time, possibly increase benefits. We’ll still have sex for all the other wonderful reasons we have it today, just less for reproduction. There will always be a critical place in our world for Italian romantics!
What are dangers of genetic hackers, perhaps especially if everyone’s DNA is eventually transcribed for medical purposes and available on the internet and in the cloud?
The sky is really the limit for how we can use gentic technologies to do things we may want, and the sky is also the limit for potential harms. It’s quite easy to imagine scenarios in which malevolent actors create synthetic pathogens designed to wreak havoc, or where people steal and abuse other people’s genetic information. It wouldn’t even need to be malevolent actors. Even well-intentioned researchers making unintended mistakes could cause real harm, as we may have seen with COVID-19 if, as appears likely to me, the pandemic stems for a research related incident]. That’s why we need strong governance and regulatory systems to optimize benefits and minimize potential harms. I was honored to have served on the World Health Organization Expert Advisory Committee on Human Genome Editing, were we developed a proposed framework for how this might best be achieved.
You foresee the equivalent of a genetic arms race between the world's most powerful countries. In what sense are genetic technologies similar to weapons?
Genetic technologies could be used to create incredibly powerful bioweapons or to build gene drives with the potential to crash entire ecosystems. That’s why thoughtful regulation is in order. Because the benefits of mastering and deploying these technologies are so great, there’s also a real danger of a genetics arms race. This could be extremely dangerous and will need to be prevented.
In your book, you express concern that states lacking Western conceptions of human rights are especially prone to misusing the science of genetics. Does this same concern apply to private companies? How much can we trust them to control and wield these technologies?
This is a conversation about science and technology but it’s really a conversation about values. If we don’t agree on what core values should be promoted, it will be nearly impossible to agree on what actions do and do not make sense. We need norms, laws, and values frameworks that apply to everyone, including governments, corporations, researchers, healthcare providers, DiY bio hobbyists, and everyone else.
We have co-evolved with our technology for a very long time. Many of our deepest beliefs have formed in that context and will continue to do so. But as we take for ourselves the powers we have attributed to our various gods, many of these beliefs will be challenged. We can not and must not jettison our beliefs in the face of technology, and must instead make sure our most cherished values guide the application of our most powerful technologies.
A conversation on international norms is in full swing in the field of AI, prompted by the release of ChatGPT4 earlier this year. Are there ways in which it’s inefficient, shortsighted or otherwise problematic for these discussions on gene technologies, AI and other advances to be occurring in silos? In addition to more specific guidelines, is there something to be gained from developing a universal set of norms and values that applies more broadly to all innovation?
AI is yet another technology where the potential to do great good is tied to the potential to inflict signifcant harm. It makes no sense that we tend to treat each technology on its own rather than looking at the entire category of challenges. For sure, we need to very rapidly ramp up our efforts with regard to AI norm-setting, regulations, and governance at all levels. But just doing that will be kind of like generating a flu vaccine for each individual flu strain. Far better to build a universal flu vaccine addressing common elements of all flu viruses of concern.
That’s why we also need to be far more deliberate in both building a global operating systems based around the mutual responsibilities of our global interdependence and, under that umbrella, a broader system for helping us govern and regulate revolutionary technologies. Such a process might begin with a large international conference, the equivalent of Rio 1992 for climate change, but then quickly work to establish and share best practices, help build parallel institutions in all countries so people and governamts can talk with each other, and do everything possible to maximize benefits and minimize risks at all levels in an ongoing and dynamic way.
At what point might genetic enhancements lead to a reclassfication of modified humans as another species?
We’ll still all be fellow humans for a very, very long time. We already have lots of variation between us. That is the essence of biology. Will some humans, at some point in the future, leave Earth and spend generations elsewhere? I believe so. In those new environments, humans will evolve, over time, differently than those if us who remain on this planet? This may sound like science fiction, but the sci-fi future is coming at us faster than most people realize.
Is the concept of human being changing?
Yes. It always has and always will.
Another big question raised in your book: what limits should we impose on the freedom to manipulate genetics?
Different societies will come to different conclusion on this critical question. I am sympathetic to the argument that people should have lots of say over their own bodies, which why I support abortion rights even though I recognize that an abortion can be a violent procedure. But it would be insane and self-defeating to say that individuals have an unlimited right to manipulate their own or their future children’s heritable genetics. The future of human life is all of our concern and must be regulated, albeit wisely.
In some cases, such as when we have the ability to prevent a deadly genetic disroder, it might be highly ethical to manipulate other human beings. In other circumstances, the genetic engineering of humans might be highly unethical. The key point is to avoid asking this question in a binary manner. We need to weigh the costs and benefits of each type of intervention. We need societal and global infrastrucutres to do that well. We don’t yet have those but we need them badly.
Can you tell us more about your next book?
The Great Biohack: Recasting Lifee in an Age of Revolutionary Technology, will come out in May 2024. It explores what the intersecting AI, genetics, and biotechnology revolutions will mean for the future of life on earth, including our healthcare, agriculture, industry, computing, and everything else. We are at a transitional moment for life on earth, equivalent to the dawn of agriculture, electricity, and industrialization. The key differentiator between better and worse outcomes is what we do today, at this early stage of this new transformation. The book describes what’s happening, what’s at stake, and what we each and all can and, frankly, must do to build the type of future we’d like to inhabit.
You’ve been a leader of international efforts calling for a full investigation into COVID-19 origins and are the founder of the global movement OneShared.World. What problem are you trying to solve through OneShared.World?
The biggest challenge we face today is the mismatch between the nature of our biggest problems, global and common, and the absence of a sufficient framework for addressing that entire category of challenges. The totally avoidable COVID-19 pandemic is one example of the extremet costs of the status quo. OneShared.World is our effort to fight for an upgrade in our world’s global operating system, based around the mutual responsibilities of interdependence. We’ve had global OS upgrades before after the Thirty Years War and after World War II, but wouldn’t it be better to make the necessary changes now to prevent a crisis of that level stemming from a nuclear war, ecosystem collapse, or deadlier synthetic biology pandemic rather than waiting until after? Revolutionary science is a global issue that must be wisely managed at every level if it is to be wisely managed at all.
How do we ensure that revolutionary technologies benefit humanity instead of undermining it?
That is the essential question. It’s why I’ve written Hacking Darwin, am writing The Great Biohack, and doing the rest of my work. If we want scietific revolutions to help, rather than hurt, us, we must all play a role building that future. This isn’t just a conversation about science, it’s about how we can draw on our most cherished values to guide the optimal development of science and technology for the common good. That must be everyone’s business.
