Unfortunately I have not enough time to look at the site you mention, but statistics are just statistics; my mother once spoke to a friend paediatrician (in Italy) - what I remember is that he was as surprised as we were that measles is now regarded as a killer when it used to be an ordinary childhood ailment nobody was afraid of; it was a necessary evil and families often got their children to infect each other, to get it over and done with; I had it at 2, my sister at 5, and I simply cannot accept that it causes the things you say; mumps only causes male infertility if caught by an adult male, not if caught by a child; rubella causes deformity and deafness in the unborn child if caught by a pregnant mother, not if caught by a child. Therefore, mumps and rubella inoculations could be given at any time before puberty. They don't need to be given at one year of age; another point is that I know from experiece (I have loads of friends with young children, my daughter's friends) that in reality, most children are vaccinated some time between 12 and 18 months and almost never the minute they are 12 months; so assuming that measles is the killer they say it is (and I simply cannot accept that) then it would be quite alright to give a single injection for measles at 12 months exactly, and wait for the other injections. Another point: the government claim (but don't give reasons so far as I know) that separate injections will not protect the child's immature immune system unless the gap is 12 months; in Japan, separate injections are given for measles and rubella on the same day (or so I read in a newspaper a few days ago), mumps is only given on request; yet the "complications" have gone right down, so the point about having to wait 12 months cannot be right; sorry I can't remember the newspaper, but we read the Guardian, the Observer, the Independent and the Eve Standard, so I can never remember which.
