I'm curious if you know if any of these studies are looking for people who had pretty bad bouts with COVID and who have autoimmune issues. I had a rough time of it with COVID in March and I have had Guillain Barre syndrome in the past and also have an auto-immune type of arthritis. I've wondered if there was a correlation. I've done the 23andMe one. I don't fit into their blood-type results very well though--I'm O negative.
