Type A positive here. Got first shot of Moderna on January 19. Just had a sore arm for a few days. Got second shot on February 16.
Next day felt tired, headache and generally felt lousy. Just slept a lot. Next day took some aspirin and was able to play golf, though not at 100 percent. Was 100 percent after a few more days. Sore arm like after the first shot as well.
I've read where Type A's have more side effects especially after the second shot. Type O doing the best. Also, heard negative blood types do better.
This is in line with what I’ve read where Type A having the most severe cases of Covid.
Anecdotal evidence in my small circle shows that Type A's have more side effects and type O doing the best.
