My first had it, my second hasn't because he had already had measles at 10 months plus was displaying a few red flags for autism, and I did not want to take the risk.
I shall be vaccinating him against mumps as soon as he is a bit older and I can afford the vaccine. However the whole process of trying to find out about single vaccs has put me off slightly - the nurse at our practice refused to even discuss it, did not wish to take blood to test his immunity for measles (HPA swabbed him but it was inconclusive) and basically clammed up completely when I mentioned not having the MMR.
Why the secrecy, why the beaurocracy...it's baffling. I think the govt has a duty of care to make the single vaccs readily and freely available.
I don't rely on herd immunity, that would be selfish unless I had another reason not to vaccinate my children - however I think most people who don't give the MMR DO have a good reason, and that's lack of faith in its safety. It's lost public confidence, and I believe the govt has ulterior motives for encouraging its use almost to the point of making it compulsory.,,not sure what these are, possibly large stockpiles waiting to be used, or similar...who knows.
I don't judge the parents, despite being very angry that because of the loss of confidence and subsequent low uptake, ds was exposed to measles at a vulnerable age.
I blame the government for their handling of it. I'd bet you that atleast 95% of parents refusing the MMR would opt for singles if they could afford and access them.
