Nah definitely had it twice when I was little, the certificatey thing is somewhere - though I might check that later, just to see. It 's maybe something like they did an extra dose due to a measles outbreak but then I'm sure that others would have had the injection too.. Am dithering over phoning GP tommorow anyway so may mention this if I do, dunno. Think you are right about it not having any effects though, something tells me the immune system would just fight off the injection if given again (but it's a long time since I've done anything human biology related..)
That said, there is an NHS website saying that the MMR was introduced in 1988 and the booster in 1996 so apparently people born pre 1992 only got one injection.. Even *that* doesn't add up as my mum remembers me having two!
