I’ve had the flu vaccine twice in my life, both in the 2000-2008 time frame. Both times, I got what seemed like the flu immediately afterwards.
No shots since then. Yeah, Ive had the seasonal cold/flu a couple of times, but that’s just part of life. Take care of yourself, chicken noodle soup, balanced diet - all helps to lessen the symptoms and speeds recovery.
I’ve had flu at least a couple of times, once pretty severely. Bird or swine or whatever they cooked up.... used my own herbs and so on, no big problem. Last vax I had for anything was when I was 10...
