[2009 Aug] LITTLE KNOWN FACTS ABOUT POLIOMYELITIS VACCINATIONS by Viera Scheibner     These days, when a vaccinee develops poliomyelitis, it may not be called poliomyelitis; instead, it may be called viral or aseptic meningitis, ascending paralysis (Guillain-Barre syndrome), cerebral palsy (over 75 per cent of cases are not diagnosed at birth but after six months) or other such names. According to MMWR (1997; 32[29]:384-385), there are 30,000 to 50,000 cases of aseptic meningitis every year in the United States. Considering that the vast majority (99 per cent) of the reported cases in the pre-vaccine era were non-paralytic and would have corresponded to aseptic or aviral meningitis, then vaccination has actually increased the incidence of poliomyelitis. In the pre-vaccine era, such high numbers only occurred in some epidemics. Now, such numbers occur every year, year by year.
