Answers
3-in-1 Teenage Booster: frequently asked questions
Why is a tetanus booster needed as a teenager?
Protection from earlier doses gradually fades, so a teenage booster maintains immunity against tetanus, diphtheria and polio into adult life. It also means most adults do not need routine boosters unless at particular risk.
Do adults need further tetanus boosters?
Most people who complete the childhood course and teenage booster are protected for life and only need extra doses for certain wounds or travel. Your GP or a travel clinic can advise if a booster is needed.
