Are some blood types able to fight coronavirus better than other blood types?

A study published in The New England Journal of Medicine found that people with Type A blood have a higher risk of getting infected with coronavirus and developing severe symptoms, while people with Type O blood have a lower risk – but the study has caveats.

The researchers cannot say if blood type is a direct cause of the differences in susceptibility. It could be that genetic changes that affect someone’s risk also just happen to be linked with blood type, they said.

The study’s findings, while plausible, may mean very little for the average person, said Dr. Roy Silverstein, a hematologist and chairman of the department of medicine at the Medical College of Wisconsin.

“The absolute difference in risk is very small,” he said. “The risk reduction may be statistically significant, but it is a small change in actual risk. You never would tell somebody who was Type O that they were at smaller risk of infection.”

The bottom line: “All of us are susceptible to this virus,” said Dr. Maria Van Kerkhove, technical lead for the World Health Organization’s Covid-19 response.
