I don't know if I mentioned this earlier or not but I've volunteered to be Phizer's guinea pig. So far, I've received two injections of what might either be their COVID-19 vaccine or a placebo. At this point, I don't know which. I have had no reaction more than what one might expect from getting a couple of CCs of saline solution injected in one's shoulder. I know two other folks who are volunteers and neither has had any reaction. Essentially we all suspect we got the placebo, which defies the odds. Time will tell, as I plan to have my doc add an antibody test when he next orders blood tests. Overall, the worst part of the process is getting a nasal swab at every visit.
