My nephew has been diagnosed with a probable mild case of Measles. He has had the MMR but my ds 22mths hasn't, I've been holding off giving him the MMR and finally booked him in for it next friday. What should i do he has been around ds, ds has a cold and has been sick and sleepy, should i phone doctors, could he have it? I thought you couldn't get Measles if you've had the MMR. Anyone got any advice
