A report came out this year that the study linking immunizations with childhood illnesses such as autism was FALSE. It was a scam for the ego of the author.
It is important to know if the shots you had as a child actually “took”. I found out in my fourth pregnancy that I was NOT immune for rubella and my pediatrician gave me the shot again when I took my baby in for his 4 week check up. My OB tested me for immunity through his series of blood tests.
