You still looking through that same lame bias lens.
You should really commit yourself to ending your narrow mindedness and willingness to swallow everything coming your way.
Tell us oh wizard - how long did it take to inoculate America's children?
Hint: Polio vaccination in the US started in 1950
(*Your stated 1963 approval was for an oral vaccine instead of the injection already in use - and they used the same needle for everybody*)
Do you know what was an even more impressive victory for science?
Of course you do not, so I will tell you - people could have just washed their hands before eating, drinking, or preparing either.
That's right - just rinsed that pesky polio down the ol drain.
But instead they lined up to get juiced with the dope.
Pretty impressive victory for the pharmaceutical companies, huh?
