Just an interesting story for you. My ex had a brother that had a bad reaction to his vaccinations in the late 50s. He died. The doctors told his mom it wouldn't happen again. When the next brother had his vaccines, he had the exact same reaction. Doctors told his mom she was imaging it until they had to perform a tracheotomy on him. When my ex came along they decided not to vaccinate him at all. He has never had any. I told my doctor this and they made the decision to delay the vaccines with my children until they were over 6 months of age. I believe it was primarily the whooping cough vaccine that they suspected. Was it just a bizarre coincidence or is there some genetic problem or bad vaccine? We will never know but it was not enough of a worry for me to leave my children unprotected against all the diseases that vaccines protect against.
