I chose to have my three vaccinated. Although many children who have been vaccinated still get the disease, it is almost always a much milder dose. Interestingly, after I had DS and he had his Varicella vaccine I mentioned to the GP that I had never had chicken pox. We checked my immunity with a BT and I had NO immunity. Odd, because I have worked in medical for the past 15 years but had somehow managed to avoid exposure to chicken pox - which is a nasty disease in adults. I also chose to be vaccinated and my immunity is now good!
