Polio was already almost gone before vaccines came in and the cases spiked.
There a lot of people that can’t comprehend that maybe some vaccines aren’t great, and maybe some do a lot of harm.
I know my thoughts on it, but it is amazing how many are brainwashed. God made me, I’ll trust that.
This is about as lenient as I am going to go, but for some people drugs like penicillin or aspirin are harmful. For a subset.
