Ok, so the CDC is covering it up do you have any proof of that? When you have asked me to prove something I have. So I would like some unbiased sources. When I googled "diagnostic criteria for polio changed" the only sites that came up were insidevaccines.com, whale, vaxtruth.org, homeoprophylaxis.com and other anti vaccine sites. For me, that raises a red flag. If my proof of something was a blog written by a staunchly pro vaccine doctor you probably would take that information with a grain of salt. Which is fine, you can believe or not believe whatever you like as can I. I find sources like the CDC, WHO, NIH to be reputable sources and you may disagree. This is a debate board after all. But when there is no real evidence because the CDC "pretends like it never happened" that screams conspiracy theory to me. That is my personal opinion and I am entitled to it.
As for the oral polio vaccine, that hasn't been used in the US in 13 years because of the risk of vaccine-associated paralytic poliomyelitis. The CDC decided the risks outweighed the benefits and discontinued it here.
Are you asking me to prove that the diagnostic criteria of polio changed? The testimony of Dr. Bernard Greenberg, who chaired the Committee on Evaluation and Standards for the American Public Health Association DURING the polio epidemic isn't good enough for you?
I've looked for anything refuting his testimony, and there's -- nothing. Honestly, I can't find any indication that it didn't change. If YOU can, by all means, please post it.
Post sources telling us that, during the early 1950's and before, people who were ill with flu-like symptoms, and then developed paralysis were EVER diagnosed with anything but polio. Show us the graphs of cases of acute flaccid paralysis, cocksackie, meningitis, Guillain-Barre Syndrome, and how those numbers AND DIAGNSOTIC CRITERIA compared with those of polio.
There is quite a lot of documentation on this page: http://www.homeoprophylaxis.com.au/FamiliesTravellers/Polio/tabid/1013/Default.aspx
"His [Dr. Bernard Greenberg's] testimony in regard to aseptic meningitis is further supported by the LA County Health Index of the same era where the total number of cases remains unchanged despite the shift in diagnosis:
Jul 1955 a)50 b)273
Jul 1961 a)161 b)65
Jul 1963 a)151 b)31
Sep 1966 a)256 b)5
Oct 1966 a)312 b)3
"Most cases reported prior to July 1, 1958 as non-paralytic poliomyelitis are now reported as viral or aseptic meningitis."
Teacozy, you need to learn to look beyond the blogs and "anti-vaccine" (or what I might call, "pro-safety") sites, and look at their sources, because, once again, you're shooting the messenger before you even read the message. It doesn't matter if a blog is pro-vaccine or anti-vaccine. What matters is whether they are telling the truth.
