Some studies have concluded that people with blood Type O may be less likely to get COVID. Can being blood Type O protect you from COVID? This seems to be because it’s physically harder for the virus that causes COVID to enter the cells of people who have Type O blood. The increase depended on the variant involved - with the Omicron variant being the worst culprit. Researchers found that having Type A blood was associated with between a 25% to 50% increased risk of getting COVID. Now there’s even more evidence that the virus that causes COVID is better at infecting people with Type A blood, as compared to Type O. The risk of death increased for people with Type AB and decreased for people with Type A and B. People with Type A had a lower risk of needing intubation, and people with Type AB and B had an increased risk. study of 14,112 people: This study found a slightly higher risk of infection among all blood types except in people with Type O. And people with Type O had a lower risk.įrench study of 1,279 military members: This study didn’t find a relationship between blood type and the risk of COVID infection. study of 107,796 people: This study didn’t find any relationship between blood type and COVID risk or disease severity.Ĭanadian study of 398,671 people critically ill with COVID: People with Type A or AB had a higher risk of needing a ventilator and having a longer stay in the intensive care unit (ICU), compared to people with Type O and B.Ĭhinese study of 2,173 people: People with Type A blood had an increased risk of getting infected with COVID. Here are some of the highlights over the past few years: On the other hand, some studies found no connection at all. And people with blood group O seemed to be less likely to get it. Early on in the pandemic, researchers noticed that people with blood group A seemed to be more likely to get sick with COVID. Over the past several years, researchers have tried to answer this question using the available data. Is there a link between blood type and COVID risk? And researchers are looking at whether having a certain blood type can increase your risk of getting COVID infection or of having severe symptoms. Different blood types are also linked to certain health conditions, like heart attacks and blood clots. Knowing your blood type is important for several reasons, like if you need a blood transfusion. So there are eight different blood types: A+, A-, B+, B-, O+, O-, AB+, AB. Blood types can be further classified by a protein called the “Rh factor.” This is either present (+) or absent (-). There are four main blood types: A, B, AB, and O. Over the years, many people have wondered if blood type plays a role in the body’s ability to protect against COVID infection.
