The Covid vaccine made me feel a 'icky' for a couple of days.. but nothing to write home about. I remember once a pneumonia shot damn near paralyzed my arm it hurt so bad but none since then have been at all bad. Never got the flu from a flu shot... no effect at all.
Got a flu shot due, I think... I don't know how people remember those type of things. Doctors always ask me, "Are you up to date on your vaccinations"... and I always reply, "how in the hell would I know.. isn't that YOUR department"? - JamesJM
