My DD (5) had the MMR today, she had one single measles and rubella when she was a baby, but was told she wasn't covered.
She had it today and boy did she scream 
I gave the red book to the nurse and she just shoo'd use out of the room and told me to fill it in. Surely she should do that as it had batch numbers etc.
Or does it really not matter, she's had it which is the main thing.
