If the flu shot works for you, I’m glad you got it. Sounds like your doctor’s office has the system error-proof.
I had very bad luck with the flu shot years ago, swore I would never get another one, and haven’t fallen ill with the flu since!
I never got the flu shot until I had it so bad in 2008 that I thought I would die. So did my doctor. I ran a fever of 106 for two days. I started taking it after that and haven’t had the flu since. Since then she nags me about it. She even emails me to get it. The first time I took the shot though they made me sit for 30 minutes to make sure I wouldn’t have a reaction.
I have a friend in WA that can’t take any kind of vaxxes without a life-threatening reaction. She is restricted from going almost anywhere in WA because she can’t take the vax.
I’m not taking the covid vax though.
