We don’t take the flu vaccine for any reason. I have not had the flu in 25 years.
Mg wife took tamiflu because she was so sick. She was not the same person while on it. I know the fever and stress were tearing her down but I really think those pills messed with her head too. She seems to be back to normal now. No flu shot. Picked up the bug on a cross country flight.
The flipside of that is:
I have asthma and lung damage from industrial processes and materials. I got the flu almost every year and it was affecting me worse each time. Since starting to take the flu vaccine more than 15 years ago I have not had the flu once.
