Single MRR Vaccines - London, Who and where?

[Gnomehead]

Can anyone recommend a doctor who is particularly knowledgeable about the MMR vaccine both single and combined?
Also, for those who live in London who have gone for the singles where did they go to have them? At the moment I have a company called e-med who can do it and they are based out of St John and Lizzies.

Thanks!
