Why are children still getting chicken pox?

Growing up in the 80s chicken pox was fairly common. But when I had my own kids I thought it was a disease of the past. We have vaccines now and I hadn't heard of it for many years. Then my daughter woke up with some suspicious spots. Too many to be an attack of mosquitos in the middle of winter. Dr Deb Levy is a paediatrician and mum. She explains why chicken pox is still around, how to identify it and what to do about it.See omnystudio.com/listener for privacy information.
