MMR Vaccine

Im having to have some jabs ready for my trip. Today I went to my GP and questions were raised over whether I was protected against measels of all things. I had assumed I was, however the balance of probability suggested not. The measels jab was introduced in 1968 but the national uptake was low. I had had everything going at the time but was measels offered. Not sure. To be safe I could be re-immunised but it would mean the combined MMR vaccine. Did the protection offered outweigh the perceived risk. At the end of the day you sometimes have to put your trust in the professionals you have selected to look after you. I had the injection.
