The AB group fared a bit worse than the A group, but the B group had no greater risk or benefit.   You can’t change your blood group, but you can avoid infection.  Those with A or AB groups should be even more obsessive about avoiding exposures.   https://www.medrxiv.org/content/10.1101/2020.03.11.20031096v1.full.pdf   #covid19 #coronavirus #abogroups #bloodgroups
