It is the next injection they are getting right? At 9 months, I just read that it should be given at 1 year, but anyway. They had a whole show about it on The Doctors a couple of weeks back. The Autism community believe that the MMR injection is directly related to their child's autism, saying that they became 'different' after receiving the injection and later being diagnosed with autism.
Anyway, don't take it too seriously because here's what I think about it: Children who have autism has always had it and something triggers it, perhaps it is the injection but then again any number of things could trigger it down the line if they don't receive the injection.
And according to me children in SA aren't allowed to go to school if they didn't get all their injections, I know my sister's oldest didn't get her injection at 2 or something and the school said she couldn't start before she's had it.
