My wife is a healthcare worker, she just got her second of the Pfizer vaccine, and she's had no adverse reaction or felt bad at all. She's 62. She did tell me a couple of her co-workers didn't feel that great for a day or so after their first shot, but bounced back pretty quick.
I'm 66, she's got me an appointment where she works to start my series. I'm retired a year and a half from healthcare (RN 37 years). I got out of it just in time.
