Unintended events following immunization with MMR: a systematic review
Vaccine 2003;21:3954-3960

?The design and reporting of safety outcomes in MMR vaccine studies, both pre- and post-marketing, are largely inadequate.?
Discussion.
?We found limited evidence of safety of MMR compared with its single-component vaccines from low risk of bias studies?.
Reputable single jab providers will tell you which strain of measles is being used anyway. When ds1 had his jab we were given far more info about it than the baby ones and the batch number was very carefully recorded in his red book (unforuntately its not listed for his baby NHS jabs)
I wasn't talking about that though- I was referring to the fact that you said the Wakefield studies were fatally flawed and then said "The most likely theory is that if the child is suspectible to autism then it may be that MMR (or even single jabs for that matter) may trigger it." - which is the Wakefield hypothesis!
