How often is a tetanus booster recommended?

• A. Every 10 years
• B. Every 5 years
• C. Every 20 years
• D. Never

Answer: (A)

Immunity from the tetanus vaccine wanes over time, so a booster is needed to keep protection at a protective level. The standard practice for adults is to receive a tetanus booster every 10 years. This interval reliably restores antibody levels and keeps the immune system ready to respond if exposed to the toxin. Often this booster is given as Tdap once in adulthood to also cover pertussis, followed by Td boosters every 10 years thereafter. In wound situations, a booster may be advised sooner if the last dose was more than 5 years ago for a dirty or severe wound, but the regular interval for ongoing protection remains 10 years.
