Last December, the FDA reported on both the Pfizer-BioNTech and Moderna Covid-19 vaccine and the respective race and ethnicity of their research participants in the Phases 2 and 3 research trials. The Pfizer trial included ages 16 or older and the Moderna trial included those 18 and older. Of 285 million in the United States population, over 40 thousand participated in the Pfizer trials and over 27 thousand in the Moderna trial. When looking at the combined totals of subjects compared to the general population, whites were found to be over represented. Whereas 73.6% of the U.S. population are white, 79.4% to 81.9% of the subjects reported their race as white. American Indian/Alaska Native and Native Hawaiian or Other Pacific Islanders had the exact percentage of research participants to those of the U.S. population; 0.8% and 0.2%, respectively. The second largest contrast in proportion of participants to the U.S. population was seen in comparing those of Asian race. Only 9.7-9.8% of research subjects reported themselves as Asian, whereas the total U.S. population percentage is 5.9%. The biggest discrepancy can be seen in research participants who reported their race as Black. Only 9.7-9.8% of research subjects were Black, whereas Blacks make up 12.3% the current total U.S. population. Regarding ethnicity, 17.6% of the U.S. population reports themselves as being Hispanic and 20-26% of participants identified themselves of Hispanic ethnicity. However, 82.4% of Americans report themselves as non-Hispanic and 73.2% to 79.1% of research subjects identified themselves as that ethnicity.

Despite these Covid-19 vaccine trials demonstrating greater diversity than previous trials of other pharmaceuticals, these statistics still represent a disparity in the representation of people of color as research participants in a vaccine designed to boost the immunity of a virus that is disproportionately affecting people of color in the United States.
