I agree as myself am allergic to a compound used in vaccines, i am rhesus negative and had to have anti d given quite a lot i had 6 pregnancies but 4 babies. Both my younger 2 are displaying hyperactivity and delayed motor skills also sound sensitivity, my youngest had a seizures after having the mmr, so i am dreading the booster but i will be keeping a close eye on her, she also lost speech and tantrums were very severe head banging until she bruised her forehead she still can be quite bad but not as severe, her speech is very unclear i can understand her but no one else can and even i struggle sometimes she is 2 and half.
