Travel Vaccination

Chickenpox Vaccine

Protection for adults without natural immunity, especially before long trips abroad.

What is chickenpox, and why does immunity matter for travel?

Chickenpox is caused by the varicella-zoster virus and spreads easily through respiratory droplets and contact with the rash. It causes an itchy, blistering rash along with fever and tiredness, and tends to be more severe in adults than in children.

Most people in the UK catch it in childhood and are immune for life, but some adults never had it. That matters more abroad, where access to care may be limited, and it's particularly relevant for anyone planning a pregnancy or working closely with children or vulnerable people overseas.

Questions about the chickenpox vaccine

Do I need this if I had chickenpox as a child?

No. Natural infection generally gives lifelong immunity, so the vaccine is mainly for those who haven't had it.

What if I'm not sure whether I've had it?

A simple blood test can confirm whether you're already immune before deciding on vaccination.

Can I have this vaccine if I'm pregnant?

No, it's a live vaccine and isn't suitable during pregnancy. It should be completed before you try to conceive.

Are there any side effects?

A mild rash or soreness at the injection site can occur. Your clinician will talk you through what to expect.
