Just wondering why you think it has to be given at 12 - 15 months.
To prevent spread of infection amongst primary and school age children.
"Later vaccinations were tried"
When?
In the 1970's and 80's when girls were vaccinated at secondary school.
Although as has been pointed out it can be v mild/asymptomatic while still being contagious which is why pregnant women shouldn't be relying on others to protect them.
Nothing wrong with suggesting that women who are trying to conceive should check their immunity. However, given that it is not possible to vaccinate everyone and some people will not plan to get pregnant and some people just won't want to go to a doctor, the most effective way of preventing CRS is to reduce the likelihood of catching MMR in the first place.
Vaccinating boys and girls pre-puberty rather than pre-school would increase the population who don't have immunity at a time when they are most likely to catch and spread infectious diseases.
No, not always looking for 100% just trying to point out that you can't just push your 'good guesses' onto people who make different decisions to you.
You don't have to agree with what I say. I am just a random on the internet.
However, the biggest reason why the current policy is unlikely to change is not me, a random on the internet. It's all the respected statisticians, epidemiologists, doctors and research scientists who advise the government, presumably because they care about children, not because they are in the pay of vaccine companies.
Anyway, whatever, mumsnet do about this board, I don't think it is likely to remove tin foil hat wearers from the internet.
