Hi. I have read that the majority of children`s vaccinations do not contain any live culture in Australia. The exceptions - and I have found some debate on this to whether the following is true is the Chicken Pox and MMR vaccine. My second son will be 18mths next month. Thus old enough for the Chicken Pox vaccine. I will be nearly 30 weeks gestation at this point. My question is- Is it safe to vaccinate children with a live virus vaccination while pregnant?
