What should I do if I missed the second dose of chickenpox vaccination?

Chicken pox and shingles are the same virus but in different forms. Chicken Pox is usually the first presentation, which typically happens in younger individuals and with a characteristic patten of blisters, crusting and a trunkal rash, while Shingles tends to happen later and can be associated with painful blisters in a nerve distribution. The varicella virus sits within the nerve endings, after the initial Chicken Pox infection, and if you become unwell or your immune system is under attack, it can develop as a secondary infection.

Chickenpox is a virus that hides inside our body forever. It hides in the nerve cells, and sometimes when your immunity is poor, it can flare up and become shingles/zoster. Our body will continue to produce antibodies (immunity) to control the virus. There is no need to get a chickenpox vaccine in this case.
