My mothers neighbour was paralyzed after a vaccine. Iam pretty sure it was the flu shot, but I cannot say for certain.
It took her a full year of therapy to re-learn speaking, and moving. She still moves a little oddly.
She is vehnemtly against all vaccines. She thought to shock me by saying she was trying to convince her grandaughter not to vaccinate her newborn, adn I told her I agreed adn dd was not vaccinated. She looked very surprised then said "and there is nothing wrong with her is there?"

, she then started sending her granddaughter my way for walks and chats.
I don't know what the girl decided to do in the end, hopefully she researched the idea and came to an informed choice.
