LAS VEGAS (KTNV) — Two recent studies report people with certain blood types may be protected more from COVID-19.
The first of the studies looked at nearly 500,000 people who tested COVID-19 positive, and Danish researchers suggested people with Type O blood may be less likely to get infected.
The second study out of Canada found among 95 critically ill patients that those with Type O or Type B blood tended to have a shorter stay in intensive care and were less likely to need a ventilator.
People with Type O blood have two sets of antibodies and people with Type A or Type B have one set.
This is one of the theories scientists have about why blood types may matter in the fight against the coronavirus.
