How often are Td/Tdap boosters recommended?

The recommendation for Td/Tdap (tetanus and diphtheria, and tetanus, diphtheria, and pertussis) boosters is generally every 10 years. This schedule is based on the need to maintain immunity against these infections, particularly tetanus and diphtheria, which can be serious conditions.

The Td booster is usually given every 10 years for adults, and if a person has never received Tdap, they should receive it at least once in place of a Td booster. After the initial series, the Td booster continues to be indicated every 10 years to ensure adequate protection.

Given this guidance, a 10-year interval allows for sustained immunological protection while also acknowledging that immunity may decrease over time. Regular adherence to this schedule is crucial in reducing the risk of these preventable diseases.
