One vaccination does not automatically offer protection
against a disease for life. Many vaccines need to be routinely boosted
to offer continued protection.
The following chart gives some idea of how often
boosters should be administered according to the UK Guidelines.
This chart is offered as a guideline and should be used together
with specialist advice from your travel health advisor.
Before travel you should ensure you have had all
of your childhood routine vaccinations.
