My mother in law never had the flu until she got a flu shot...maybe 10 years ago.
It’s all part of the Green Plan; Depopulation.
That’s the reason I refuse to get a flu shot. The last time I did I got sick as a dog. My doc said it’s because the flu shot weakens the immune system and it rebuilds to normal with the addition of resistance to the flu.
I haven’t had one since and only caught the flu once in about 2012. Put me on my back for 3 days, but that’s the only time.
