So, the short answer is “Probably not.” I did a little digging on this because I heard the recently confirmed HHS Secretary Robert F. Kennedy Jr (RFK Jr) cite studies which he says did indicate there are differences in humoral immunity between Caucasians and African Americans.
Now remember, I’m a retired general hospital psychiatric consultant and my immunology background consists of the standard immunology lecture in medical school. The class I remember most vividly was the one in which the lecturer stopped her lecture abruptly, sighed deeply and looked defeated, probably because she saw the look of confusion on our faces.
Now that you know my credentials, let me just review what I found in a far from exhaustive review of the scientific literature on the topic of whether or not African Americans have, as RFK Jr. remarked, a “better” immune system than Caucasians.
On my own, I found what RFK Jr referred to variously (depending what social media web source you use) as the “Poland” or “pollen” studies as the scientific source of information supporting his view. I suspect it’s this, in which the last author in the citation is GA Poland:
Haralambieva IH, Salk HM, Lambert ND, Ovsyannikova IG, Kennedy RB, Warner ND, Pankratz VS, Poland GA. Associations between race, sex and immune response variations to rubella vaccination in two independent cohorts. Vaccine. 2014 Apr 7;32(17):1946-53. doi: 10.1016/j.vaccine.2014.01.090. Epub 2014 Feb 13. PMID: 24530932; PMCID: PMC3980440.
It was later in the day that I finally also found the NPR news story, the author of which pointed out the same article.
I also found a couple of other articles which tend to contradict the findings of the Poland et al study. One of them was published in eClinicalMedicine in 2023:
Martin CA, Nazareth J, Jarkhi A, Pan D, Das M, Logan N, Scott S, Bryant L, Abeywickrama N, Adeoye O, Ahmed A, Asif A, Bandi S, George N, Gohar M, Gray LJ, Kaszuba R, Mangwani J, Martin M, Moorthy A, Renals V, Teece L, Vail D, Khunti K, Moss P, Tattersall A, Hallis B, Otter AD, Rowe C, Willett BJ, Haldar P, Cooper A, Pareek M. Ethnic differences in cellular and humoral immune responses to SARS-CoV-2 vaccination in UK healthcare workers: a cross-sectional analysis. EClinicalMedicine. 2023 Apr;58:101926. doi: 10.1016/j.eclinm.2023.101926. Epub 2023 Apr 4. PMID: 37034357; PMCID: PMC10071048.
The list of references include the Poland study (reference 27) cited above. The bottom line is the African American immune response to Covid is not “better” than that of white health care workers but the Asian immune response was stronger. I thought it was interesting that in the section “Evidence before this study,” the authors point out that in one previous study, African Americans had lower antibody responses to vaccination than Whites.
I looked at only one other study, published in Clinical Microbiology Review in 2019;
Zimmermann P, Curtis N2019.Factors That Influence the Immune Response to Vaccination. Clin Microbiol Rev 32:10.1128/cmr.00084-18.https://doi.org/10.1128/cmr.00084-18
OK, so I didn’t hunt through all 582 references, but I thought it was enough to note that the authors didn’t mention race as even being relevant anywhere in the body of the paper.
That said, I suspect the more important fact to focus on is racial disparity regarding African Americans even getting vaccines, especially the Covid vaccine. Vaccine hesitancy is common in this population and probably more important to address rather than whether or not there are significant racial differences in immunogenicity. The major challenge is providing accurate information about vaccines in general and Covid vaccines in particular.
The CDC Advisory Committee includes African American members who attend each meeting and emphasize the importance of including black people in vaccination campaigns. OK, so why was the meeting this month cancelled, postponed, or whatever?
Hey, I’m just an old psychiatrist, so don’t take my word for it about anything here. Ask an immunologist. If the immunologist gives you a blank look, you could try a Ouija Board.
