Whenever you get into an argument with a vaccine believooor, they always pound the table on the Polio vax as a success story.
But they've never actually looked at the case graph leading up to when the polio 💉 was introduced.

Why am I seeing it was introduced in1955? Totally with you on polio propaganda though
Ironically, the polio story is possibly the best reason for being antivax:

It's the same for all vaccines. By the time the vaccine comes out, the disease has already naturally been erradicated, and the vaccine takes false credit.
