We have a DS who is 5. He was exposed to chicken pox last Thursday, played all afternoon in an enclosed space with a child whose spots came out two days later. So, he probably has it unless he has some sort of immunity or whatever.
DN (17) has lived with us since he was 12 before that he was brought up by his GM. As soon as I found out I asked him to check with GM what happened with his chicken pox - she has just got back to me and she is SURE he hasn't had it.
What should I do? Should he get the vaccine?
