I had a pretty severe case months before getting the Pfizer and just some soreness, a little headache and maybe a lymph node swelled a bit but all gone in a day or so. I will see after I get my second tomorrow what happens. Hope it is the same.
I can't see any pattern to who has severe symptoms with the virus or severe reactions to the vaccine, tricky little bug we are dealing with.
The one good pattern I do see, is that pretty much everyone I have heard getting side effects, also said they were completely gone in 24/36 hours. Never even had a flu that went away that quick.
