I am 36wks pregnant, and still working PT - peripatetic teacher. I got an email saying the school I am tomorrow has a couple cases of rubella and chicken pox. I called my doc who said if I have had them/been immunised then I will be fine. I know this must be true, and I had the rubella vaccine at high school, and had cp as a child, but still feel uneasy about going in tomorrow. Please tell me not to be silly!!
