My grandson aged 3 has just had his MMR, polio, whooping cough and diphtheria vaccines. The nurse told my daughter that he should stay away from anyone on Chemo for 2 weeks. They are all due to come to me for lunch on Sunday. I called the specialist nurse at my hospital and she said that she had never heard of this and as long as he is well, no runny nose, sneezes etc it should be fine. Has anyone else come across this before? I wonder if the nurse is following some written guidelines or just being ultra cautious.
