Women overreacting is an old and tired stereotype — but there’s some truth to it, at least immunologically speaking.
In a new study, researchers found that women’s immune systems responded more strongly than men’s to flu vaccine. Old and young women alike produced both more antibodies and a higher inflammatory cytokine count — one sign of potential immunological overreaction — than male participants.
His vs. Hers Immune System
While the gender gap in immune reactions has long been known, the mechanism behind it has remained a mystery. But in this study, the scientists identified a handful of genes, apparently regulated by testosterone, that they think are a key part of the response mechanism. The higher the testosterone levels of a participant, the lower the immunological reaction to vaccination.
