Who should consider the chickenpox vaccine?
Most UK adults had chickenpox as children and are immune for life, so the vaccine is aimed at those who have never had it and are not immune. The NHS offers the varicella vaccine to non-immune people at higher risk, and for travellers it can be sensible before long trips, for those in close contact with local communities, or where access to medical care is limited, because chickenpox tends to be more severe in adults.
How it works
The vaccine is given as two doses, usually a few weeks apart. Because it is a live vaccine, your pharmacist will check it is suitable for you, particularly if you are pregnant or have a weakened immune system. If you are unsure whether you have had chickenpox, a conversation at the appointment will help decide whether the vaccine or a check is the right step.
What to expect
Most people have only a sore arm, and occasionally a few spots or mild tiredness as the vaccine works. Serious reactions are rare. Your pharmacist goes through the patient information first; suspected reactions can be reported to the MHRA Yellow Card scheme.
Timing
Allow time for two doses before travel where possible. If your trip is sooner, your pharmacist will advise on what is achievable and worthwhile.
Common questions
Q: I had chickenpox as a child, do I need the vaccine?
A: Usually not. Childhood chickenpox generally gives lifelong immunity; the vaccine is for those who never had it.
Q: How many doses are needed?
A: Two doses, usually a few weeks apart.
Q: Why consider it for travel?
A: Chickenpox can be more serious in adults, so non-immune adults may want cover before longer trips.
