MMR is not risk free - nothing is. When you feed your child strawberries, you risk them getting anaphylactic shock - even if they've eaten them happily before. If you give them Calpol or antibiotics, you risk an allergic reaction. NOTHING is without risk - it's about weighing up the risks.
MMR is very, very, very safe. The risk of a child developing a serious reaction requiring hospital admission is about 1 in 100,000 - that's 10 in a million. None of those children, however, have ever died - there's not one recorded death anywhere in the world caused by MMR.
There's plenty from measles.
No study anywhere has ever found a link between MMR and autism. Not a single one. In countries where 3 jabs were offered instead of combined, the rates of autism have not gone down.
Some children do develop autism - and since so many children are vaccinated early in life, most of those will have had the MMR, some quite recently. This does not mean there's a link between the two. There isn't.
Refusing to listen to your doctor, ignoring the advice of every medical scientist IN THE WORLD to get your child vaccinated is arrogant and selfish. And please don't dress it up as "concern" to guilt trip the rest of us - where is your concern for the children who genuinely can't have the vaccine and who could be infected by yours?
If the medical advice for your particular child is "don't" absolutely fair enough. We would hope that your child would be protected by herd immunity. This won't happen if people refuse simply because they think they know better than the doctors. Disgraceful.
