I don't vaccinate with MMR. It is not 100% safe, nothing is, I object to the rubella element contained in the MMR, a 13 month old doesn't need to be protected against a disease that is dangerous to a pregnant woman. Since the mumps vaccine is to protect against adult male infertility I object too to giving this vaccine to a child. So I object , on moral grounds, to the rubella and mumps elements of the MMR.
As for measles, I'll risk measles, to me it's a risk that I'm happy with. Everything in life has a risk and some risks I accept.
I have a moral objection to consenting to my child taking on a risk (however small) to protect someone else's child. I'm sorry your child has measles OP but I can't, in all good conscience, risk my child to protect your child.
You expect other people to vaccinate to protect your child, if a child is damaged by a vaccine will you be there to help out with round the clock care? I suspect not.
This brings me to another point, why direct your anger at me, what about directing it to vaccine manufacturers and asking why we can't have a vaccine that is much more effective and after only one dose, a dose which can be given earlier than 13 months.
