So, i seemed to have missed the memo.
Apparently, for the first time, this years new intake to uni (ie current 18 year olds) are recommended to have a Men C booster which you can get from your GP and should have before they head off.
This is because those born after Sept 1995 will have had the first round as a baby or toddler (my DD had it when she was 4, i checked) and the effectiveness wears off. if they are older and had it as a school age child (which my elder two did -8 and 10 ) it will still be effective (and they are past the second wave age of likely getting the disease)
So i thought I'd mention it in case anyone else, like me, didnt know..... put it on your departing DC's list of things to do!
