Thanks Siduhe, I was aware of these figures, wrong link I put above?? I believe it is extremely difficult for parents who believe there children to be damaged by vaccines, to pursue there claim. http://www.foiacentre.com/FOIA-news.html If you click on foia wins mmr appeal, and then the archives, where warnings were given about the MMR in 1988, the year my brother was born. My mother told me at that time there were two diffrent companies making the vaccines, each with same strains except for the mumps, which had 10 times more international units of the strain, after attending an appointment, a health visitor made for her, to see a doctor because she was refusng to give us vaccines, he had no idea which one they used at the clinic.
