R&I NV — People with blood type O may be less vulnerable to Covid-19 and have a reduced likelihood of getting severely ill, according to two studies published Wednesday. Experts say more research is needed.
The research provides further evidence that blood type (also known as blood group) may play a role in a person’s susceptibility to infection and their chance of having a severe bout of the disease. The reasons for this link aren’t clear and more research is needed to say what implications, if any, it has for patients.

Most humans fall into one of four blood groups: A, B, AB or O. In the United States, the most common blood groups are O and A.
It makes very little difference to most people’s daily lives unless you have to have a blood transfusion. Nor should people worry unduly about the link between blood type and Covid-19, said Dr. Torben Barington, the senior author of the Danish paper and a clinical professor at Odense University Hospital and the University of Southern Denmark.
“We do not know whether this is some kind of protection of group O, or whether it’s some kind of vulnerability in the other blood groups,” he said.
“I think this has scientific interest, and when we find out what the mechanism is, perhaps we’re able to use that proactively in some way in regard to treatment.”
