"The reason the government has dug in is that MMR is manufactured here, is effective and safe." Having spoken to someone at GSK - manufacturers of Priorix - and Sanofi Pasteur MSD - manufacturers of MMR-VaxPro, that comment is not necessarily true, if "here" you meant as England - it depends where exactly "here" is.
Try to find out for yourself exactly where (location wise) the 2 licenced MMR vaccines are manufacturered. You will be for a surprise.
Anyway, cockneysparrow1977,
I don't know if you are still reading this thread, but just to say that I know how you feel as my family is in the same position. My oldests have had the single vaccines and I was intending for this to be the case for my youngest.
However, the GP who previously gave the single vaccines to my other children has moved, so I had to find an alternative clinic -a long way away. Then I discovered that Merck no longer manufacture Attenuvax and Rouvax's export from France has been restricted by the French Government. Anyway, to cut a long story short (OP can PM for the longer version), I have opted out for the MMR for my youngest. Probably against my better judgement, we will find out in 10 - 20 day's time or whenever.
My husband and I rarely row, but this issue has caused serious friction between us. My husband says single vaccine or nothing. I have opted for the MMR. Time will tell if that was the correct decision.
In the meantime, I would like to give you a massive hug. Whatever decision you chose, will be the right one.
