My wife works in healthcare and has had the first and second doses. The first does was just a mildly sore arm, the second does kicked her butt and she was sick enough to come home early that day. She took some ibuprofen and woke up fine the next day so went right back to work - nothing out of the ordinary for vaccine shots. I've lost family members to COVID, my neighbors and friends have lost family members to COVID, and I'll be getting the vaccine as soon as I am allowed to.
