Does anybody know if it is possible to get measles or german measles even if MMR jab was given at 15 months? My DS1 is nearly 4 and has all the symptoms of measles - apart from the pin-prick pink/red rash - his is white, rough, bumpy skin. But he has dry cough, sneezing, aches in limbs, fatigue, swollen lymph nodes behind both ears.
