Coronavirus: 'Essential' that black people are included in vaccine trials, experts warn

'If the distrust pre-Covid-19 was strong, the chances are even less now that black people will participate'

A coronavirus vaccine will only be successful if black participants are included in clinical trials, experts have warned.

Medical experts have expressed fear that black people are not being proportionately represented in Covid-19 trials and have said that their participation is critical.

Researchers stress that medicine could produce different results based on race and genetic, socioeconomic and environmental dynamics, and need to be accounted for during clinical trials.

“Genetics related to racial differences make it essential that we be involved in broad-based and diverse clinical trials of medications and vaccines,” Dr Larry Graham, a retired pulmonologist, told NBC News.

“The expanding discipline of pharmacogenetics has taught us that we may respond differently than other races to both medicines and vaccines. We must be sure it works in black folks. This can only be determined by our inclusion in the research-based trials of such vaccines.”

Pharmacogenetics is the study of how people respond differently to drug therapy based upon their genetic makeup or genes.

Data has emerged throughout the pandemic showing that African Americans are being disproportionately affected by the virus, both in terms of infections and deaths.

Experts say there are several reasons for this including a number of socio-economic factors such as limited access to healthcare.

“Over the last couple of decades we’ve seen conservative forces destroying the social safety net. And it’s meant black communities and brown communities and indigenous communities, have pre-existing conditions that make individuals more susceptible to the worst ravages of Covid-19,” Aimee Allison, founder of She the People, a group that works to promote the political power of women of colour, said.

“Those pre-existing conditions are caused by socio-economic factors. You can’t shelter in place if you don’t have shelter.”

Black people are largely reluctant to participate in medical trials due to deep mistrust of experimental drugs and medical institutions due to historical experience, experts told NBC news.

Distrust of black Americans in medical research often derives from examples such as the Tuskegee Study of Untreated Syphilis that began in 1932. For the 40-year study, 399 syphilis infected black men were enlisted to the trial and offered free medical exams, free meals, and burial insurance.

The men were not given any effective treatment, only placebos, and 28 of the men died of syphilis while 100 died of related complications. A number of the wives and children of the men were also infected.

Calethia Hodges works to persuade black people to participate in trials, but has said that predispositions are “tough to overcome”.

“The reasons I hear African Americans will not participate are heartbreaking and disappointing,” Ms Hodges told NBC News.

“I have heard about the Tuskegee experiment a lot. And I have heard 'They [doctors] will give me the virus.' And 'They will put a chip inside me.' Many say their parents raised them 'to never participate in medical research.' It's all tough to overcome.”

Other experts also note that institutions have also failed to push the inclusion of black Americans in the number of vaccine studies under way.

“There is a fear with Covid-19 how intentional the hundreds of trials are about diversity,” Dr Aletha Maybank, the American Medical Association's chief equity officer and group vice president of its Centre for Health told the outlet.

“I'm not clear and would make the assumption that they are not intentional. If so, I haven't heard about it yet.

"But if the distrust pre-Covid-19 was strong, the chances are even less now that black people will participate. I worry about exploitation and medicines' being used on patients without their knowledge or consent.”

Dr John Maupin, the former president of Meharry Medical College and Morehouse School of Medicine, argued that the country needs more historically black colleges and universities (HBCUs) conducting research to build trust.

“We have to have more [HBCUs conducting trials] because people will trust them more than they will some other institutions. I'm not saying all are untrustworthy. I'm saying there would be greater trust in institutions led by those who come from the patients' backgrounds.”

Dr Maybank said that building relationships is key to convincing people to participate in the trials and trust research.

“Folks doing work from leading institutions have asked, 'How do we build trust?' Well, it's not rocket science. It's about building relationships."

"Are you getting to know me beforehand? Are you speaking in a language I understand? Are the concepts broken down so that they are digestible? Are you present? Are you giving resources to our neighbourhoods beforehand? That's not rocket science."
