You need a tetanus shot every 10 years to maintain protection against tetanus. After completing the initial series of tetanus vaccinations in childhood, booster shots are recommended every 10 years throughout adulthood
. Details on the vaccination schedule:
- Children: Receive a series of 5 DTaP shots at 2 months, 4 months, 6 months, 15–18 months, and 4–6 years old
- Preteens and Teens: One Tdap booster shot at 11 to 12 years old
- Adults: A Tdap or Td booster every 10 years
If you get a wound that is deep, dirty, or contaminated, and it has been more than 5 years since your last booster, you may need a tetanus shot sooner
. There is some research suggesting that immunity might last longer than 10 years, possibly up to 30 years after the initial series, but current official recommendations still advise boosters every 10 years for adults
. In summary, the standard medical guidance is to get a tetanus booster shot every 10 years to ensure ongoing protection.
