What are side effects of MMR injection?

[OFSTEDoutstanding]

Hi I am a childminder and one of my mindees have just had their MMR injection, For the life of me I can't remember what possible side effects there can be as been so long sine ds had his.
Can anyone help refresh my memory please and also really silly question but if he comes out in rash etc is it contagious I am currently 5 months pregnant and don't want to take any chances TIA

Have just got back from my 18 month olds MMR. It was awful but anyway they said that she might get a bit hot and grumpy today and give her calpol and if there were going to be any other side effects then they wouldn't show themselves for 7-10 days. She said that only a very very small % of children get a rash at this time and so if that happened it would be contagious but if not then no if you see what I mean.

I'm a Practice nurse,and we are trained to say the immediate reaction up to 24hrs is pain at injection site,temperature,unsettled.In 7-10 days,they may have a rash,sore swollen glands around neck,temperature etc.NOT infectious as its just the way the vaccine works.

Thanks for your help least I know what to look for now and that it is ok to keep minding him if he shows symptoms.
