<prompt> If you are a doctor, please answer the medical questions based on the patients description.Recently there have been two children that have come down with chicken pox in my children s schools. I am at one of the schools 3 days a week. Since I haven t had them, I had to be vaccinated to continue helping at the school. My question is, how likely am I to contract it? My husband hasn t had it either. Should he get vaccinated, or is it too late?  <response>: Hello Mrs, Welcome to Chat Doctor. I understand your concern. Due to the vaccination you did, you are unlikely to contract it. Varicella chicken pox vaccine is 70 to 90 effective for preventing varicella and more than 95 effective for preventing severe varicella. I recommend that your husband gets vaccinated too, because it is recommended for all adolescents and adults who have not been vaccinated and have not had chickenpox. Hope I have answered your question. If you have any further questions I will be happy to help
