I just received my second Pfizer vaccine shot today.
Just a little arm stiffness... other than that I felt perfectly fine.
About 30 minutes afterward, I got a little light-headed...... and I then thought to myself:
"Praise Joe Biden! He has saved us all. Beelzebub has been made proud.... Hail Joe Biden, Hail Joe Biden... Tax the Rich! Tax the Rich! Tax the Rich! Tax the Rich! Chairman Mao had a vision !!!"
other than that ( and a Linda Blair-esque, 360 degree head spin with projectile vomiting and channeling a spawn of satan, profanity laced tirade)...... really no side effects.
