Black Participants Are Sorely Absent from Medical Research
After years of suffering from mysterious symptoms, my mother Janice Thomas finally found a doctor who correctly diagnosed her with two autoimmune diseases, Lupus and Sjogren's. Both diseases are more prevalent in the black population than in other races and are often misdiagnosed.
The National Institutes of Health has found that minorities make up less than 10 percent of trial participants.
Like many chronic health conditions, a lack of understanding persists about their causes, individual manifestations, and best treatment strategies.
On the search for relief from chronic pain, my mother started researching options and decided to participate in clinical trials as a way to gain much-needed insights. In return, she received discounted medical testing and has played an active role in finding answers for all.
"When my doctor told me I could get financial or medical benefits from participating in clinical trials for the same test I was already doing, I figured it would be an easy way to get some answers at little to no cost," she says.
As a person of color, her presence in clinical studies is rare. The National Institutes of Health has found that minorities make up less than 10 percent of trial participants.
Without trial participation that is reflective of the general population, pharmaceutical companies and medical professionals are left guessing how various drugs work across racial lines. For example, albuterol, a widely used asthma treatment, was found to have decreased effectiveness for black American and Puerto Rican children. Many high mortality conditions, like cancer, also show different outcomes based on race.
Over the last decade, the pervasive lack of representation has left communities of color demanding higher levels of involvement in the research process. However, no consensus yet exists on how best to achieve this.
But experts suggest that before we can improve black participation in medical studies, key misconceptions must be addressed, such as the false assumption that such patients are unwilling to participate because they distrust scientists.
Jill A. Fisher, a professor in the Center for Bioethics at the University of North Carolina at Chapel Hill, learned in one study that mistrust wasn't the main barrier for black Americans. "There is a lot of evidence that researchers' recruitment of black Americans is generally poorly done, with many black patients simply not asked," Fisher says. "Moreover, the underrepresentation of black Americans is primarily true for efficacy trials - those testing whether an investigational drug might therapeutically benefit patients with specific illnesses."
Without increased minority participation, research will not accurately reflect the diversity of the general population.
Dr. Joyce Balls-Berry, a psychiatric epidemiologist and health educator, agrees that black Americans are often overlooked in the process. One study she conducted found that "enrollment of minorities in clinical trials meant using a variety of culturally appropriate strategies to engage participants," she explained.
To overcome this hurdle, The National Black Church Initiative (NBCI), a faith-based organization made up of 34,000 churches and over 15.7 million African Americans, last year urged the Food and Drug Administration to mandate diversity in all clinical trials before approving a drug or device. However, the FDA declined to implement the mandate, declaring that they don't have the authority to regulate diversity in clinical trials.
"African Americans have not been successfully incorporated into the advancement of medicine and research technologies as legitimate and natural born citizens of this country," admonishes NBCI's president Rev. Anthony Evans.
His words conjure a reminder of the medical system's insidious history for people of color. The most infamous incident is the Tuskegee syphilis scandal, in which white government doctors perpetrated harmful experiments on hundreds of unsuspecting black men for forty years, until the research was shut down in the early 1970s.
Today, in the second decade of twenty-first century, the pernicious narrative that blacks are outsiders in science and medicine must be challenged, says Dr. Danielle N. Lee, assistant professor of biological sciences at Southern Illinois University. And having majority white participants in clinical trials only furthers the notion that "whiteness" is the default.
According to Lee, black individuals often see themselves disconnected from scientific and medical processes. "One of the critiques with science and medical research is that communities of color, and black communities in particular, regard ourselves as outsiders of science," Lee says. "We are othered."
Without increased minority participation, research will not accurately reflect the diversity of the general population.
"We are all human, but we are different, and yes, even different populations of people require modified medical responses," she points out.
Another obstacle is that many trials have health requirements that exclude black Americans, like not wanting individuals who have high blood pressure or a history of stroke. Considering that this group faces health disparities at a higher rate than whites, this eliminates eligibility for millions of potential participants.
One way to increase the diversity in sample participation without an FDA mandate is to include more black Americans in both volunteer and clinical roles during the research process to increase accountability in treatment, education, and advocacy.
"When more of us participate in clinical trials, we help build out the basic data sets that account for health disparities from the start, not after the fact," Lee says. She also suggests that researchers involve black patient representatives throughout the clinical trial process, from the study design to the interpretation of results.
"This allows for the black community to give insight on how to increase trial enrollment and help reduce stigma," she explains.
Thankfully, partnerships are popping up like the one between The Howard University's Cancer Center and Driver, a platform that connects cancer patients to treatment and trials. These sorts of targeted and culturally tailored efforts allow black patients to receive assistance from well-respected organizations.
Some observers suggest that the federal government and pharmaceutical industries must step up to address the gap.
However, some experts say that the black community should not be held solely responsible for solving a problem it did not cause. Instead, some observers suggest that the federal government and pharmaceutical industries must step up to address the gap.
According to Balls-Berry, socioeconomic barriers like transportation, time off work, and childcare related to trial participation must be removed. "These are real-world issues and yet many times researchers have not included these things in their budgets."
When asked to comment, a spokesperson for BIO, the world's largest biotech trade association, emailed the following statement:
"BIO believes that that our members' products and services should address the needs of a diverse population, and enhancing participation in clinical trials by a diverse patient population is a priority for BIO and our member companies. By investing in patient education to improve awareness of clinical trial opportunities, we can reduce disparities in clinical research to better reflect the country's changing demographics."
For my mother, the patient suffering from autoimmune disease, the need for broad participation in medical research is clear. "Without clinical trials, we would have less diagnosis and solutions to diseases," she says. "I think it's an underutilized resource."
Bivalent Boosters for Young Children Are Elusive. The Search Is On for Ways to Improve Access.
It’s Theo’s* first time in the snow. Wide-eyed, he totters outside holding his father’s hand. Sarah Holmes feels great joy in watching her 18-month-old son experience the world, “His genuine wonder and excitement gives me so much hope.”
In the summer of 2021, two months after Theo was born, Holmes, a behavioral health provider in Nebraska lost her grandparents to COVID-19. Both were vaccinated and thought they could unmask without any risk. “My grandfather was a veteran, and really trusted the government and faith leaders saying that COVID-19 wasn’t a threat anymore,” she says.” The state of emergency in Louisiana had ended and that was the message from the people they respected. “That is what killed them.”
The current official public health messaging is that regardless of what variant is circulating, the best way to be protected is to get vaccinated. These warnings no longer mention masking, or any of the other Swiss-cheese layers of mitigation that were prevalent in the early days of this ongoing pandemic.
The problem with the prevailing, vaccine centered strategy is that if you are a parent with children under five, barriers to access are real. In many cases, meaningful tools and changes that would address these obstacles are lacking, such as offering vaccines at more locations, mandating masks at these sites, and providing paid leave time to get the shots.
Children are at risk
Data presented at the most recent FDA advisory panel on COVID-19 vaccines showed that in the last year infants under six months had the third highest rate of hospitalization. “From the beginning, the message has been that kids don’t get COVID, and then the message was, well kids get COVID, but it’s not serious,” says Elias Kass, a pediatrician in Seattle. “Then they waited so long on the initial vaccines that by the time kids could get vaccinated, the majority of them had been infected.”
A closer look at the data from the CDC also reveals that from January 2022 to January 2023 children aged 6 to 23 months were more likely to be hospitalized than all other vaccine eligible pediatric age groups.
“We sort of forced an entire generation of kids to be infected with a novel virus and just don't give a shit, like nobody cares about kids,” Kass says. In some cases, COVID has wreaked havoc with the immune systems of very young children at his practice, making them vulnerable to other illnesses, he said. “And now we have kids that have had COVID two or three times, and we don’t know what is going to happen to them.”
Jumping through hurdles
Children under five were the last group to have an emergency use authorization (EUA) granted for the COVID-19 vaccine, a year and a half after adult vaccine approval. In June 2022, 30,000 sites were initially available for children across the country. Six months later, when boosters became available, there were only 5,000.
Currently, only 3.8% of children under two have completed a primary series, according to the CDC. An even more abysmal 0.2% under two have gotten a booster.
Ariadne Labs, a health center affiliated with Harvard, is trying to understand why these gaps exist. In conjunction with Boston Children’s Hospital, they have created a vaccine equity planner that maps the locations of vaccine deserts based on factors such as social vulnerability indexes and transportation access.
“People are having to travel farther because the sites are just few and far between,” says Benjy Renton, a research assistant at Ariadne.
Michelle Baltes-Breitwisch, a pharmacist, and her two-year-old daughter, Charlee, live in Iowa. When the boosters first came out she expected her toddler could get it close to home, but her husband had to drive Charlee four hours roundtrip.
This experience hasn’t been uncommon, especially in rural parts of the U.S. If parents wanted vaccines for their young children shortly after approval, they faced the prospect of loading babies and toddlers, famous for their calm demeanor, into cars for lengthy rides. The situation continues today. Mrs. Smith*, a grant writer and non-profit advisor who lives in Idaho, is still unable to get her child the bivalent booster because a two-hour one-way drive in winter weather isn’t possible.
It can be more difficult for low wage earners to take time off, which poses challenges especially in a number of rural counties across the country, where weekend hours for getting the shots may be limited.
Protect Their Future (PTF), a grassroots organization focusing on advocacy for the health care of children, hears from parents several times a week who are having trouble finding vaccines. The vaccine rollout “has been a total mess,” says Tamara Lea Spira, co-founder of PTF “It’s been very hard for people to access vaccines for children, particularly those under three.”
Seventeen states have passed laws that give pharmacists authority to vaccinate as young as six months. Under federal law, the minimum age in other states is three. Even in the states that allow vaccination of toddlers, each pharmacy chain varies. Some require prescriptions.
It takes time to make phone calls to confirm availability and book appointments online. “So it means that the parents who are getting their children vaccinated are those who are even more motivated and with the time and the resources to understand whether and how their kids can get vaccinated,” says Tiffany Green, an associate professor in population health sciences at the University of Wisconsin at Madison.
Green adds, “And then we have the contraction of vaccine availability in terms of sites…who is most likely to be affected? It's the usual suspects, children of color, disabled children, low-income children.”
It can be more difficult for low wage earners to take time off, which poses challenges especially in a number of rural counties across the country, where weekend hours for getting the shots may be limited. In Bibb County, Ala., vaccinations take place only on Wednesdays from 1:45 to 3:00 pm.
“People who are focused on putting food on the table or stressed about having enough money to pay rent aren't going to prioritize getting vaccinated that day,” says Julia Raifman, assistant professor of health law, policy and management at Boston University. She created the COVID-19 U.S. State Policy Database, which tracks state health and economic policies related to the pandemic.
Most states in the U.S. lack paid sick leave policies, and the average paid sick days with private employers is about one week. Green says, “I think COVID should have been a wake-up call that this is necessary.”
Maskless waiting rooms
For her son, Holmes spent hours making phone calls but could uncover no clear answers. No one could estimate an arrival date for the booster. “It disappoints me greatly that the process for locating COVID-19 vaccinations for young children requires so much legwork in terms of time and resources,” she says.
In January, she found a pharmacy 30 minutes away that could vaccinate Theo. With her son being too young to mask, she waited in the car with him as long as possible to avoid a busy, maskless waiting room.
Kids under two, such as Theo, are advised not to wear masks, which make it too hard for them to breathe. With masking policies a rarity these days, waiting rooms for vaccines present another barrier to access. Even in healthcare settings, current CDC guidance only requires masking during high transmission or when treating COVID positive patients directly.
“This is a group that is really left behind,” says Raifman. “They cannot wear masks themselves. They really depend on others around them wearing masks. There's not even one train car they can go on if their parents need to take public transportation… and not risk COVID transmission.”
Yet another challenge is presented for those who don’t speak English or Spanish. According to Translators without Borders, 65 million people in America speak a language other than English. Most state departments of health have a COVID-19 web page that redirects to the federal vaccines.gov in English, with an option to translate to Spanish only.
The main avenue for accessing information on vaccines relies on an internet connection, but 22 percent of rural Americans lack broadband access. “People who lack digital access, or don’t speak English…or know how to navigate or work with computers are unable to use that service and then don’t have access to the vaccines because they just don’t know how to get to them,” Jirmanus, an affiliate of the FXB Center for Health and Human Rights at Harvard and a member of The People’s CDC explains. She sees this issue frequently when working with immigrant communities in Massachusetts. “You really have to meet people where they’re at, and that means physically where they’re at.”
Equitable solutions
Grassroots and advocacy organizations like PTF have been filling a lot of the holes left by spotty federal policy. “In many ways this collective care has been as important as our gains to access the vaccine itself,” says Spira, the PTF co-founder.
PTF facilitates peer-to-peer networks of parents that offer support to each other. At least one parent in the group has crowdsourced information on locations that are providing vaccines for the very young and created a spreadsheet displaying vaccine locations. “It is incredible to me still that this vacuum of information and support exists, and it took a totally grassroots and volunteer effort of parents and physicians to try and respond to this need.” says Spira.
Kass, who is also affiliated with PTF, has been vaccinating any child who comes to his independent practice, regardless of whether they’re one of his patients or have insurance. “I think putting everything on retail pharmacies is not appropriate. By the time the kids' vaccines were released, all of our mass vaccination sites had been taken down.” A big way to help parents and pediatricians would be to allow mixing and matching. Any child who has had the full Pfizer series has had to forgo a bivalent booster.
“I think getting those first two or three doses into kids should still be a priority, and I don’t want to lose sight of all that,” states Renton, the researcher at Ariadne Labs. Through the vaccine equity planner, he has been trying to see if there are places where mobile clinics can go to improve access. Renton continues to work with local and state planners to aid in vaccine planning. “I think any way we can make that process a lot easier…will go a long way into building vaccine confidence and getting people vaccinated,” Renton says.

Other changes need to come from the CDC. Even though the CDC “has this historic reputation and a mission of valuing equity and promoting health,” Jirmanus says, “they’re really failing. The emphasis on personal responsibility is leaving a lot of people behind.” She believes another avenue for more equitable access is creating legislation for upgraded ventilation in indoor public spaces.
Given the gaps in state policies, federal leadership matters, Raifman says. With the FDA leaning toward a yearly COVID vaccine, an equity lens from the CDC will be even more critical. “We can have data driven approaches to using evidence based policies like mask policies, when and where they're most important,” she says. Raifman wants to see a sustainable system of vaccine delivery across the country complemented with a surge preparedness plan.
With the public health emergency ending and vaccines going to the private market sometime in 2023, it seems unlikely that vaccine access is going to improve. Now more than ever, ”We need to be able to extend to people the choice of not being infected with COVID,” Jirmanus says.

What causes aging? In a paper published last month, Dr. David Sinclair, Professor in the Department of Genetics at Harvard Medical School, reports that he and his co-authors have found the answer. Harnessing this knowledge, Dr. Sinclair was able to reverse this process, making mice younger, according to the study published in the journal Cell.
I talked with Dr. Sinclair about his new study for the latest episode of Making Sense of Science. Turning back the clock on mouse age through what’s called epigenetic reprogramming – and understanding why animals get older in the first place – are key steps toward finding therapies for healthier aging in humans. We also talked about questions that have been raised about the research.
