As a side note I was fully vaccinated as a baby and had it really bad with chicken pox that I was rushed to hospital. I still have a scar on my lip from it.
We don't get NHS chickenpox vaccinations here; I think you can pay for it privately though.
Should have mentioned, I grew up in Australia and received the vaccine.
I didn't think the chickenpox vaccine was introduced in Australia and NZ until 2000 onwards and only as part of the schedule from the mid-2000s... Are you certain you received it as a child?
