To something in the vaccine.
What is in this Pfizer vax, and what in it could cause an allergic reaction?
I’m sure I’m allergic to some component in this shot that would keep me from having to get it, but I can’t put my finger on it yet, please help me narrow down the chemical(s) I may have a reaction to, and what my reaction would look like
Thank you, which one of those is something humans can be allergic to
Probably PEG. Many people are allergic to it and can have severe allergic reactions.
