Have any of you heard of this before?

It was brought to my attention by my future father-in-law. Apparently there's a group of people claiming that the polio vaccine didn't cause the decline in polio cases, but that the decline was caused by a redefinition of meningitis, thus there was no actual decline, just a name switch, attributing the widespread use of the vaccine to corporate greed. Their evidence is that as polio declined meningitis cases rose. I haven't done much initial research, only finding crackpot websites like http://www.whale.to/vaccine/polio1.html that support the position.

I smell bullshit, but I don't like to dismiss anything out of hand so I'm coming to you guys for some collaborative assistance. I have to go and bust my ass at a piss-poor construction job in about 9 hours (student loans in the U.S. suck ass) so I'll probably try to look into it either tomorrow night or later this week.

thanks

my bullshit alarm is going off. Remember that correlation does not imply causation. Polio and meningitis are different diseases so I would say that this is just bullshit. Crazy conspiracy sites tend to be wrong.
