I also have a low immunity to rubella, which is a bit of a concern to me as I am a primary school teacher, I was just basically told to be extra vigalent and if there was any sign of an out break I was to stay well away from school etc. I had a bit of a freak out overthe Jan school holidays because I was working Vac Care for the YMCA and I got a phone call from one of the mum saying her son had measles, I freaked out but my GP told me that because I had little contact with the boy I should be fine, I just needed to stay away from the centre for at least 2 weeks, and it was only measles not German Measles so not so bad.
