I know a 96 yr old and a 101 year old, both still live on their own, and they did fine with the Pfizer shots. I was surprised they didn't have any reactions but I hear the younger people usually get hit harder because their immune systems are stronger. I question that since these two people never get sick and I think their immune systems are better than most peoples.

I feel like if you're going to take one then that's the one to take.
