We recently had a scare when my daughter contracted roseola & they did tests for rubella just in case as I was preggas, that was just b4 xmas, now my daughter has a couple of spots & I'm not sure if they're chicken pox or not, will wait & see. Although I had a small dose when I was 5yo, which wasn't enough to give immunity so then got it again worse at 19-20yo, so should well & truly be immune.
