We are moving to Australia from the UK for 3 years. I have heard that kids in Australia are vaccinated against chicken pox as part of their childhood vaccination schedule. My almost 6 year old and 2 year old have not had chicken pox and I was wondering whether to vaccinate them privately before we go. It seems they are unlikely to catch in during our time there and then I’m worried, particularly about DS2 catching it, when he’s 9 or older. Is there a way of checking whether your child is immune? DS2 sat next to a child at his childminders who came out in the spots 24 hours later and he never caught it!
