I'm quite curious about this actually! My doctors have finally set up an online booking system and it shows all of the vaccinations I've received since I was born and the only ones I've had was the Diptheria, Polio, And Tetanus at 3 months, a booster at 4 the again at 15 which I remember. It says I was due MMR but I never received it but when I had my blood tests after finding out I was pregnant, they said I was immune to rubella? Is it possible that I could've caught it when I was younger?
