I had my DS done at Breakspear, same as dinny. They were excellent (crap for parking spaces though!!!)
Rubella is licenced in this country separately because if a woman who is going to have kids is not immune, they need the jab. eg you may be found in your first pg not to be immune (everyone is tested) so once you have had the baby, they vaccinate you to protect future babies of yours.
Measles and mumps are not licenced in this country. IMO this is because the government wants everyone to have MMR and GPs try to scare parents (myself included) with "You're putting unlicenced drugs into your child". Actually, the vaccines given at Breakspear are imported and fully and properly licenced in their country of origin, which is USA, Switzerland, France etc usually (they show you the packet and provide you with the manufacturers instructions).
wheresthehamster: I really don't want to frighten you, but I am going to give you a truthful answer to your question. When MMR was first introduced (+ a few years later), I was a schoolgirl and it was given to kids of approx. your DD's age as they wouldn't have been done as babies/toddlers. I personally know a girl in my school who was severely affected at this age. I won't say anymore as I know it is controversial, but the effects are not limited to young kids. Personally, if I were you, I would get single jabs from a reputable source.
