Advice to Travellers
Ensure the British Vaccination Schedule is complete including booster doses as teenagers.
Travellers should be aware of:
- Persistence of disease in many regions of the world to which unvaccinated individuals are susceptible.
- Waning immunity from diphtheria vaccine with increasing age.
- Ten-yearly boosters of vaccine should be given for travel to endemic areas particularly where individuals will be mixing with the local population (e.g. health workers, teachers, volunteers).
- Aid workers travelling to regions with confirmed diphtheria outbreaks, who are thus likely to be exposed to infection, should be given a booster dosedose of a diphtheria-containing vaccine if they have not had one in the last 12 months.
