The anti-vax movement's wildest claim yet: "Polio wasn't so bad."

5. In the US, while Salk was developing his vaccine, polio killed more annually than 9/11.

Salk developed the vaccine in 1952, testing was done in 1953-4, licensing and rollout in 1955.

1952 was a notably bad year, yes, but only about twice recent annual averages. 3145 died and 21,000+ were left paralyzed to some degree that year. And the population of the US was much smaller then (about 150M).

But think about those numbers for a second. A totally avoidable 9/11, disproportionately children, annually is "not so bad" according to these ghouls.
