I quit reading about side effects to meds. After the 2nd shingles vaccine, it seems I now get every reaction they warn about. I thought it was in my head but no, I have problems with many meds now. Getting my first covid booster and the flu vaccine at the same time was a mistake. Yes, better than getting covid or a bad flu case but I have no idea which vaccine caused such a horrible reaction that lasted 3 days. And no, it didn't stop me from getting a 2nd covid booster. I'll get another if it's recommended.
