New to this thread.
DH was in the Pfizer study. He spoke to the principal investigator here back in Dec and found out he got the actual vaccine. Injection site soreness was his only side effect. (As an aside, it *really* bothers me when ppl refer to the current vaccination drive as experimental. The trials on safety and efficacy
I'm also fully vacc (Pfizer) as of Jan 23. Also had very slight arm soreness (less than with the flu shot) with both doses. Usually I have arm soreness for 24-48 hours after a flu shot; this soreness was much less in severity and lasted maybe 2 hours.
I know literally hundreds of people in group 1a, including many with underlying conditions, and I only know of one person who had side effects beyond injection site soreness. That one person is an otherwise healthy male physician in his late 40s who got fairly seriously ill with COVID a few months ago, including 104° fever for ~10 days and short hospitalization. After his second dose of the vaccine he got a 103° fever that lasted less than 24 hours.
