A recent study by genetic testing company 23andMe of 750,000 people found that those who have blood type O were almost 20% less likely to catch the COVID-19 virus than those having other blood types.
People with type O blood were between 9% and 18% less likely to test positive for the disease. Backing up that statistic was the fact that people with Type O blood who had been exposed to COVID-19 were between 13% and 26% less likely to acquire the virus.

23andMe is still recruiting for its massive study, most recently seeking 10,000 participants outside of 23andMe who have been hospitalized and diagnosed with COVID-19. 23andMe researchers have yet to finish looking at what the genetic data indicate.
[-]Preliminary Genetic Association
While it is still very early in the study, 23andMe’s preliminary investigation into genetics seems to support these findings. Comparing the research participants who reported that they tested positive for COVID-19 to those who tested negative, our researchers identified a variant in the ABO gene associated with a lower risk. (The single nucleotide polymorphism in the ABO gene is rs505922, a T at that location is associated with lower risk. The P-value for the association is 1.4e-8, OR = 0.88).
Both the data on blood type and the preliminary genetic findings also appear to support at least two recently published pre-print studies — one by researchers in China and the most recent one by researchers in Italy and Spain — that look at the ABO gene’s role in COVID-19. The study in China looked at susceptibility, while the Italian and Spanish study found an association with blood type and severity of the illness.
Numerous other studies have reported that the ABO blood group plays a role in both susceptibility and severity for COVID-19 (refs: 1, 2, 3). And we know from other studies that the ABO blood group can play a direct role in other types of infections by serving as receptors, or coreceptors for microorganisms, parasites, and viruses. The preliminary findings from 23andMe’s data are also notable because of the link between COVID-19 blood clotting, and cardiovascular disease.
