Early on in the pandemic, health experts identified blood type as a risk factor for contracting COVID-19. However, it wasn't clear exactly why people with a specific blood type were more likely to become infected with the deadly virus than those with others. Now, researchers from  Harvard University and Oklahoma Blood Institute (OBI) believe they may have the answer. Read on to learn about the new study—and to ensure your health, remember: Doctors Say "DO NOT" Do This After Your COVID Vaccine.

"It's real," Says Researcher About Link of Blood Type and COVID Risk

According to the new study, those with Type A blood are more likely to become infected with COVID-19 due to the blood type providing a "stickier" environment for the virus to cling to. 

"It's real, it's on the ground and now it's getting us a little bit of understanding of what's causing it," said Dr. John Armitage with the OBI, who started offering free antibody tests to blood donors in July, per Oklahoma's News 4. After looking at all of the blood samples, they noticed a larger number of donors with type A or AB blood types had COVID-19 antibodies compared to those with type O. "We saw a 2.5% difference in the results we get back from those two different types of donors," he said.

They believe it is because those with A type blood "have a substance very similar to their A blood group that's lining their lungs and their bronchi and respiratory tract," Armitage explained. 

"If you think of a family – maybe somebody picks up the virus in a family from an event or they've been traveling together – maybe it's a married couple and somebody gets the infection and the other doesn't – it might be related to blood group, somebody might be more susceptible with that A," Armitage said.
