For example, the idea that having type O blood is protective doesn't match up with the pattern of Covid-19 infection in the US. Type O blood is more prevalent among African Americans, yet African Americans have experienced disproportionately high infection rates. "Group O shouldn't think they aren't going to get this disease. They shouldn't be running around everywhere and not maintain social distance, nor should group A panic," he said. "There's so many underlying factors. We think of this as a respiratory virus but it's really a whole collection of things going on that we don't understand yet," he said. Research on blood types has sometimes fallen between different academic disciplines, but a better understanding of why we have different blood groups and the relationship between blood type antibodies and disease risk is likely to help us to develop vaccines and design new drugs, including for Covid-19.

Why do we have different blood types — and do they make us more vulnerable to Covid-19?
