Don’t Panic! Everything is under control. If your child gets Polio from the vaccine, the government will detect it very quickly!
They will not be able to treat it.
The main reason, is that the Type 2 virus that the vaccine was contaminated with, tends to mutate.
In some cases, this may develop into Real Polio. But don’t worry, it is safe, parents should not be concerned. Basically, your child may develop polio.
