What are the real stats on the flu especially for the aged. There are no control groups. They just line up and we assume they would have gotten the flu except they had the shot.
I had the flu in 2000. Horrible, I was sick for over a week and more than a month with Post Influenza Syndrome. A constant cough at night that kept me from sleeping. I never had the vaccine before that. I’ve taken the vaccine every year since with no flu. YMMV.
