Nancy, sorry to hear about the red patch. I go tomorrow for the first Pfizer, and I'm scared because I never did too well with ordinary flu shots. In 1957 when I was still a teen I got the flu shot and soon after came down with the most terrible case of Asian Flu, which was raging at that time. Ran a high fever for 10 days, sicker than I've ever been. My grandfather caught it, died of complications. Then, about 20 years ago, I got a flu shot and my arm swelled up for a month. At that time, I showed it to the doctor, she said never get another flu shot, and I haven't. But this Covid 19 is a killer so I'm chancing the vaccine.
