The mistake produced 120,000 doses of polio vaccine that contained live polio virus. Of children who received the vaccine, 40,000 developed abortive poliomyelitis (a form of the disease that does not involve the central nervous system), 56 developed paralytic poliomyelitis—and of these, five children died from polio.
The Cutter incident is a story of bad vaccines. The viruses were supposed to be inactivated. Cutter's were not [1].
That is not what is happening here. Nobody got a bad vaccine. This is the story of an unvaccinated individual being exposed to a weakened poliovirus, administered instead of the inactivated kind because it's sterilizing, and then going home to a community of other unvaccinated people who had no protection against polioviruses of any kind.
In both stories, vaccines are reason of infection.
I personally know few people that get Covid few days after vaccination. I don't know if they get infection in vaccination centre from others or from vaccine itself, but again... Vaccine was a reason of spreading infection.
