Historical vaccine problems

In 1955, batches of polio vaccine were given to the public, that contained live polio virus, even though they passed safety testing It was over 250 cases of polio that were attributed and produced by one company: The Cutter Laboratories. This case, was known as the Cutter Incident that resulted in many cases of paralysis. The vaccine was recalled as soon as cases of polio were detected.

The Cutter Incident was messed up moment in history of vaccine, The manufacturing and government who oversight these vaccines were dam careless or they must of been insane or stupid leasing to the creation of a people becoming paralyzed. After the government snapped out their insanity they improved this process and increased oversight of polio vaccinations in the fall of 1955.
At those old times. there was no system to sue and compensate people who have been harmed by a American vaccine. IN this ear we have the National Vaccine Injury Compensation Program External icon (VICP), which uses scientific evidence to determine whether a vaccine might be the cause of an illness or injury, and provides compensation to individuals found to have been harmed by a vaccine.

From 1955 to 1963, a estimated 10-30% of polio vaccines administered in the US were contaminated with simian virus 40 (SV40). The virus came from a monkey kidney cell cultures used to make polio vaccines at that time. Most of the contamination was in the inactivated polio vaccine (IPV), but it was also found in oral polio vaccine (OPV). After the contamination was discovered, the U.S. government established testing requirements to verify that all new lots of polio vaccines were free of SV40.

Because of research done with SV40 in animal models, there has been some concern that the virus could cause cancer in humans. However, most studies looking at the relationship between SV40 and cancers are reassuring, finding no causal association between receipt of SV40-contaminated polio vaccine and development of cancer.
