Covid infection: Scientists think blood type plays a role, and have identified which one is least at risk

People with blood type O are less likely to become infected with Covid-19, the disease caused by SARS-CoV-2, according to two new studies published in the journal Blood Advances. They are also at lower risk of severe Covid-19 outcomes, such as organ failure, and even death.

Scientists have been investigating a potential link between blood type and vulnerability to Covid-19 for many months, and this latest evidence supports previous findings.

A preprint study published in March this year suggested that people with blood type A have a higher risk of acquiring Covid-19 compared with non-A blood groups, while another study published in June found that blood type O seemed to be more resistant against Covid-19 infection.
