A recent Romanian study demonstrated that injections of antibiotics following polio vaccination could cause polio. The researchers suggested the rate of "vaccine-induced polio" in Romania could be reduced from 10.3 per year to 1.4 per year, if antibiotic injections were avoided for 30 days following polio vaccination.
Correlations with the injections of antibiotics were found: a single injection within one month of vaccination raised the risk of polio 8 times, 2 to 9 injections raised the risk 27-fold, and 10 injections or more raised the risk 182 times (Washington Post, Feb 22, 1995).

GUESS WHAT IS IN THE POLIO VACCINE???

Neomycin, streptomycin, and polymyxin B

The United States Centre for Disease Control (CDC) admitted that the vaccine has become the dominant cause of polio in the US today, with 87% of cases between 1973 and 1983 caused by the vaccine. More recently, 1980-1989, every case of polio in the US was caused by the vaccine. Doctors and scientists on the staff of the National Institute of Health during the 1950's were well aware that the Salk vaccine was ineffective and deadly. Some frankly stated that it was "worthless as a preventative and dangerous to take". The Salk "inactivated" or "killed-virus" was actually regulated to permit 5,000 live viruses per million doses
