Vaccines Are the Safest Medical Procedure We Have. Make Your Wager Wisely.
Frontline infectious disease physician Amesh Adalja received his COVID-19 vaccine on December 18th, 2020 in Butler, PA.
In the late 1650's the French polymath and renowned scientist Blaise Pascal, having undergone a religious experience that transformed him into something of a zealot, suggested the following logical strategy regarding belief in God: If there is a God, then believing in him will ensure you an eternity of bliss, while not believing in him could earn you an eternal sentence to misery.
On the other hand, if there is no God, believing in him anyway will cost you very little, and not believing in him will mean nothing in the non-existent after life. Therefore, the only sensible bet is to believe in God. This has come to be known as Pascal's wager.
It has a surprising number of applications beyond concerns for a comfortable afterlife. There are many things for which the value of believing something or not can be seen as a cost vs. likely benefit wager, often without regard to the actual truth of the matter. Since science does not profess to have a final truth, and in many areas freely admits its incomplete knowledge, Pascal's wager can provide a useful method of deciding between two alternatives.
For example, it seems that a significant percentage of the population is suspicious of science, or so we are told. We often hear that some large number, approaching or exceeding half of Americans, do not believe in evolution. This seems remarkable on the face of it because there is no viable scientific opposition to evolution and it is widely accepted by biologists and other life-scientists as being fundamental to understanding biology – from genetics to medicine.
What we are not often told is that most of those who answer negatively about believing in evolution nonetheless understand evolution – or at least the basics of it. They are not stupid, ignorant or uninformed. They have simply made a Pascalian wager. What benefit we might ask is derived from believing in evolution rather than a divine creation? Unless you are a professional biologist it is hard to see how this would affect your everyday life. On the other hand professing a belief in Darwinian evolution over the biblical narrative will likely ostracize you from family, friends, co-workers, your church community - in short most of your social infrastructure. Place your bets.
Can we apply any of this to decisions over the current controversy surrounding vaccination – and in particular the newly arrived Covid-19 vaccine?
While it is true that for entirely economic reasons, this is the first vaccine to be produced in this way, the method is not really new and the science that makes it possible has been developing over the last 40 years.
Common Concerns
There are certainly reasons to be concerned about being vaccinated and it would be a gross over-simplification to consider anyone who expresses reticence about taking a vaccine, this new vaccine in particular, as being just plain dumb or scientifically illiterate or gullible. They need be none of these things and still may be suspicious of the vaccine.
One issue is safety. The vaccine, any vaccine, is designed to mobilize your immune system, essentially to fool it into believing that there is an invading virus present and to mount an immune response. That way it will be ready when the real invasion comes, if it comes. This seems pretty sensible and preferable to going to war with an opponent you know nothing about. But still, it is fooling around with Mother Nature and some people are uneasy about that. Although it must be pointed out that the virus is not at all shy about fooling around with your immune system and many other parts of you, so letting it have its way is not good policy either.
What about a vaccine made of genes? This vaccine is being produced by what is being touted as a new method using RNA – genes. While it is true that for entirely economic reasons, this is the first vaccine to be produced in this way, the method is not really new and the science that makes it possible has been developing over the last 40 years. So it's not so radical as the press makes it seem.
But it is true that this method uses RNA, genetic material, to make the vaccine. We hear a lot about gene modification and the potential dangers associated with it. Why then am I going to allow RNA, genes, to be injected into me? The first thing to realize is that this is exactly what the virus does – so whether you get a vaccine or an infection, you are getting genes injected into you. The virus RNA encodes around 12 functional genes (by comparison humans and other mammals have around 25,000 genes). The virus only contains the genes to make a new virus – it does not have any of the capabilities of a normal cell to actually turn those genes into the proteins that make up the complete virus. It hijacks your cells to do this – and that's how it sickens you, by forcing your cells to make new viruses instead of what they should be doing.
Now the new vaccines have taken just one of those genes – the one that directs the production of the now infamous spike protein that appears on the surface of a normal virus – and injects just that one gene into your muscle cells, which then make that one single protein. Your immune system comes along and sees that weird protein and makes antibodies to it. These same antibodies will now recognize the spike protein on the surface of any viral particles that invade your body. We have effectively turned the virus into its own enemy.
The viral RNA that you are getting will decompose over a few days because RNA is not a stable molecule (that, by the way, is why the vaccine needs to be kept frozen) and it will no longer exist in your body. It could only become a permanent part of your genome if it were a DNA molecule instead of an RNA molecule – and even the chances of that happening would be chemically remote. So regardless of how it sounds, this may actually be the safest sort of vaccine to use. In the future it is likely that all vaccines will be made this way.
Then, of course, there is the issue of who is running this whole vaccine program – the government and the pharmaceutical industry. These are the guys who brought you opioid addiction, death by Vioxx, soaring drug prices, the worst health care system in the developed world, regulations where you don't need them and none where you do – am I really going to trust this cast of so-called "inept villains," as some believe, to dictate my personal health choices? Do we know for sure that the claims of efficacy are real or just made up to sell some worthless procedure? It would not be the first time. (I would not, on the other hand, worry about Bill Gates having a chip inserted into you along with the vaccine – if you use any social media, navigational tools, or purchase anything online, then Bill Gates already knows more about you than he will get from any injectable chip. So that train has left the station.)
The main upside to vaccines is that because they use your already existing defense system, they are surprisingly safe.
The Vaccine Wager
All this and a few lesser issues are worth a pause for sure. But we must also look on the positive side of the ledger. Why trust science? Modern medicine and the science behind it has eliminated or dramatically lessened such scourges as smallpox, polio, cholera, chicken pox, measles, rabies and dozens of other killer pathogens that had previously wiped out enormous numbers of people, in some cases significant parts of entire generations. Don't we depend on science for much of the comfort and safety of our everyday lives? Isn't science the way we heat our homes, drive to work, fly around the world, have dependable food? Yes, there is the bomb – but there is also anesthesia.
When it comes to viruses, the only tool we have to fight them is vaccination. The only tool. Antibiotics are for bacteria, a completely different sort of creature. Sanitation beyond personal hand washing is ineffective. Vaccines trick the immune system into recognizing the virus earlier than it would otherwise and protect normal cells from invasion by the virus. Tricking the immune system is understandably problematic for people who believe that their body knows best if it's just kept healthy. This virus, as we have seen from the array of infected people that includes apparently healthy folks, unfortunately does not subscribe to that belief.
By a similar sort of reasoning, some people make the plausible error of calculating that the vaccine is 95% effective but the survival rate is 99%, so why not just let my natural resistance take care of this? Indeed, that might not be unreasonable thinking if we were talking about the common cold, but this virus has shown itself to be a tricky character and we are not yet able to predict who gets a serious case and who a mild one. With those sorts of stakes, you shouldn't wager on either of those numbers because they have nothing to do with you as an individual. Like flipping a coin, there is only a 1% chance of it coming up heads 6 times in a row. But if it has come up heads 5 times in a row the probability of it coming up heads on the next flip is … still 50/50.
An even larger unknown is whether there may be long-term effects associated with SARS-Cov-2, as is the case for many viruses. The 1918 influenza virus has been linked to a subsequent 2-3 fold increase in Parkinson's disease by a mechanism we still don't understand. The virus that gives children chicken pox will hide out in a person's body for 40 years or more and then emerge as a painful, sometimes debilitating, case of shingles. The 99% survivability rate of this virus is meaningless if 20 years from now it causes some devastating pulmonary or brain disease.
The main upside to vaccines is that because they use your already existing defense system, they are surprisingly safe. Safer than antibiotics which have numerous side effects because they are not part of our normal make up and are cell killers – mostly bacterial cells, but they are not so perfectly targeted that they don't leave some collateral damage in their wake. All drugs and treatments have side effects, but vaccines in general have the fewest. This vaccine in particular has undergone many more than the usual safety measures - multiple independent review boards, massive press and public attention, governmental and non-governmental oversight, the most diverse trial cohorts ever assembled. Nothing here was rushed, no shortcuts were taken.
So here's the vaccine wager. Vaccines are the safest medical procedure we have. They are also among the most effective, but that's curiously not important for the bet. My claim about their safety is because vaccines are in a special class of medical tools. They are the only medical procedure or drug that is given to healthy people. Every other treatment we use medically is aimed at some existing pathology - from a cold to cancer.
Vaccines therefore have to reach a higher standard of safety than any other medical treatment. You can't take healthy people and make them sick. Vaccines have fewer side effects than virtually any other drug you wouldn't even think twice about taking – aspirin, for instance, which can cause internal bleeding, gastric ulcers, stroke. But since you are sick when you take those drugs you are willing to make the bet that the benefits will outweigh the possible side effects.
With vaccines the wager is much simpler – it is indeed more like Pascal's original wager. It may or may not be highly effective (some vaccines are only 60% effective) but they are so safe that taking them poses little risk, whereas not taking them subjects you (and others) to considerable risk, i.e., getting the virus. Like believing or not in an afterlife, the smart money is with Pascal, who I think would have reasoned himself right to the head of the vaccination line.

9 Tips for Online Mental Health Therapy
Research shows that, for most patients, online therapy offers the same benefits as in-person therapy, yet many people still resist it. A behavioral scientist explains how you can use it to improve mental health.
Telehealth offers a vast improvement in access and convenience to all sorts of medical services, and online therapy for mental health is one of the most promising case studies for telehealth. With many online therapy options available, you can choose whatever works best for you. Yet many people are hesitant about using online therapy. Even if they do give it a try, they often don’t know how to make the most effective use of this treatment modality.
Why do so many feel uncertain about online therapy? A major reason stems from its novelty. Humans are creatures of habit, prone to falling for what behavioral scientists like myself call the status quo bias, a predisposition to stick to traditional practices and behaviors. Many people reject innovative solutions even when they would be helpful. Thus, while teletherapy was available long before the pandemic, and might have fit the needs of many potential clients, relatively few took advantage of this option.
Even when we do try new methodologies, we often don’t do so effectively, because we cling to the same approaches that worked in previous situations. Scientists call this behavior functional fixedness. It’s kind of like the saying about the hammer-nail syndrome: “when you have a hammer, everything looks like a nail.”
These two mental blindspots, the status quo bias and functional fixedness, impact decision making in many areas of life. Fortunately, recent research has shown effective and pragmatic strategies to defeat these dangerous errors in judgment. The nine tips below will help you make the best decisions to get effective online therapy, based on the latest research.
Trust the science of online therapy
Extensive research shows that, for most patients, online therapy offers the same benefits as in-person therapy.
For instance, a 2014 study in the Journal of Affective Disorders reported that online treatment proved just as effective as face-to-face treatment for depression. A 2018 study, published in Journal of Psychological Disorders, found that online cognitive behavioral therapy, or CBT, was just as effective as face-to-face treatment for major depression, panic disorder, social anxiety disorder, and generalized anxiety disorder. And a 2014 study in Behaviour Research and Therapy discovered that online CBT proved effective in treating anxiety disorders, and helped lower costs of treatment.
During the forced teletherapy of COVID, therapists worried that those with serious mental health conditions would be less likely to convert to teletherapy. Yet research published in Counselling Psychology Quarterly has helped to alleviate that concern. It found that those with schizophrenia, bipolar disorder, severe depression, PTSD, and even suicidality converted to teletherapy at about the same rate as those with less severe mental health challenges.
Yet teletherapy may not be for everyone. For example, adolescents had the most varied response to teletherapy, according to a 2020 study in Family Process. Some adapted quickly and easily, while others found it awkward and anxiety-inducing. On the whole, children with trauma respond worse to online therapy, per a 2020 study in Child Abuse & Neglect. The treatment of mental health issues can sometimes require in-person interactions, such as the use of eye movement desensitization and reprocessing to treat post-traumatic stress disorder. And according to a 2020 study from the Journal of Humanistic Psychology, online therapy may not be as effective for those suffering from loneliness.
Leverage the strengths of online therapy
Online therapy is much more accessible than in-person therapy for those with a decent internet connection, webcam, mic, and digital skills. You don’t have to commute to your therapist’s office, wasting money and time. You can take much less medical leave from work, saving you money and hassle with your boss. If you live in a sparsely populated area, online therapy could allow you to access many specialized kinds of therapy that isn’t accessible locally.
Online options are much quicker compared to the long waiting lines for in-person therapy. You also have much more convenient scheduling options. And you won’t have to worry about running into someone you know in the waiting room. Online therapy is easier to conceal from others and reduces stigma. Many patients may feel more comfortable and open to sharing in the privacy and comfort of their own home.
You can use a variety of communication tools suited to your needs at any given time. Video can be used to start a relationship with a therapist and have more intense and nuanced discussions, but can be draining, especially for those with social anxiety. Voice-only may work well for less intense discussions. Email offers a useful option for long-form, well-thought-out messages. Texting is useful for quick, real-time questions, answers, and reinforcement.
Plus, online therapy is often cheaper than in-person therapy. In the midst of COVID, many insurance providers have decided to cover online therapy.
Address the weaknesses
One weakness is the requirement for appropriate technology and skills to engage in online therapy. Another is the difficulty of forming a close therapeutic relationship with your therapist. You won’t be able to communicate non-verbals as fully and the therapist will not be able to read you as well, requiring you to be more deliberate in how you express yourself.
Another important issue is that online therapy is subject to less government oversight compared to the in-person approach, which is regulated in each state, providing a baseline of quality control. As a result, you have to do more research on the providers that offer online therapy to make sure they’re reputable, use only licensed therapists, and have a clear and transparent pay structure.
Be intentional about advocating for yourself
Figure out what kind of goals you want to achieve. Consider how, within the context of your goals, you can leverage the benefits of online therapy while addressing the weaknesses. Write down and commit to achieving your goals. Remember, you need to be your own advocate, especially in the less regulated space of online therapy, so focus on being proactive in achieving your goals.
Develop your Hero’s Journey
Because online therapy can occur at various times of day through videos calls, emails and text, it might feel more open-ended and less organized, which can have advantages and disadvantages. One way you can give it more structure is to ground these interactions in the story of your self-improvement. Our minds perceive the world through narratives. Create a story of how you’ll get from where you are to where you want to go, meaning your goals.
A good template to use is the Hero’s Journey. Start the narrative with where you are, and what caused you to seek therapy. Write about the obstacles you will need to overcome, and the kind of help from a therapist that you’ll need in the process. Then, describe the final end state: how will you be better off after this journey, including what you will have learned.
Especially in online therapy, you need to be on top of things. Too many people let the therapist manage the treatment plan. As you pursue your hero’s journey, another way to organize for success is to take notes on your progress, and reevaluate how you’re doing every month with your therapist.
Identify your ideal mentor
Since it’s more difficult to be confident about the quality of service providers in an online setting, you should identify in advance the traits of your desired therapist. Every Hero’s Journey involves a mentor figure who guides the protagonist through this journey. So who’s your ideal mentor? Write out their top 10 characteristics, from most to least important.
For example, you might want someone who is:
- Empathetic
- Caring
- Good listener
- Logical
- Direct
- Questioning
- Non-judgmental
- Organized
- Curious
- Flexible
That’s my list. Depending on what challenge you’re facing and your personality and preferences, you should make your own. Then, when you are matched with a therapist, evaluate how well they fit your ideal list.
Fail fast
When you first match with a therapist, try to fail fast. That means, instead of focusing on getting treatment, focus on figuring out if the therapist is a good match based on the traits you identified above. That will enable you to move on quickly if they’re not, and it’s very much worth it to figure that out early.
Tell them your goals, your story, and your vision of your ideal mentor. Ask them whether they think they are a match, and what kind of a treatment plan they would suggest based on the information you provided. And observe them yourself in your initial interactions, focusing on whether they’re a good match. Often, you’ll find that your initial vision of your ideal mentor is incomplete, and you’ll learn through doing therapy what kind of a therapist is the best fit for you.
Choose a small but meaningful subgoal to work on first
This small subgoal should be sufficient to be meaningful and impactful for improving your mental health, but not a big stretch for you to achieve. This subgoal should be a tool for you to use to evaluate whether the therapist is indeed a good fit for you. It will also help you evaluate whether the treatment plan makes sense, or whether it needs to be revised.
Know when to wrap things up
As you approach the end of your planned work and you see you’re reaching your goals, talk to the therapist about how to wrap up rather than letting things drag on for too long. You don’t want to become dependent on therapy: it’s meant to be a temporary intervention. Some less scrupulous therapists will insist that therapy should never end and we should all stay in therapy forever, and you want to avoid falling for this line. When you reach your goals, end your therapy, unless you discover a serious new reason to continue it. Still, it may be wise to set up occasional check-ins once every three to six months to make sure you’re staying on the right track.
