The Centers for Disease Control and Prevention (CDC) recommends that adults receive a tetanus booster shot every 10 years to maintain protection against tetanus. After an initial dose of Tdap (tetanus, diphtheria, and pertussis vaccine), adults can receive either Td (tetanus and diphtheria) or Tdap for their booster doses every decade

. For children, the vaccination schedule includes a series of DTaP shots at 2, 4, and 6 months of age, with booster doses at 15–18 months and 4–6 years. Preteens should get a Tdap booster between ages 11 and 12

. If a person sustains a wound that could be contaminated (e.g., puncture wound, deep cut, or wound exposed to dirt or saliva), a tetanus booster may be recommended if they have not had one within the past 5 years

. Although some research suggests that immunity may last longer—up to 30 years after the initial childhood series—current public health guidelines continue to recommend a 10-year booster interval for adults to ensure ongoing protection

. Summary:

  • Initial childhood series of DTaP shots plus boosters through early childhood
  • Tdap booster at age 11–12
  • Adult booster (Td or Tdap) every 10 years
  • Booster within 5 years after a high-risk wound if last booster was more than 5 years ago

This schedule helps maintain immunity against tetanus throughout life
