What age group should receive the Tdap booster?

The Tdap booster is recommended for individuals aged 11-12 years as part of their routine vaccinations. This age group is critical for receiving the booster because it helps to ensure they are protected against tetanus, diphtheria, and pertussis (whooping cough), especially as they transition into adolescence when risks for these conditions can rise.

The recommendation is based on the need to enhance immunity that might have waned since the childhood vaccinations. Specifically, this booster is particularly important for preteens as it prepares them for potential exposure during adolescence and adulthood, especially since pertussis can continue to circulate in the community. Additionally, ensuring robust immunity in this age group is beneficial in protecting infants and others who may be more vulnerable to infections.

Infants under 1 year cannot safely receive the Tdap vaccine, while children aged 5-10 may have already received their primary series of vaccinations but are generally not within the age range for the Tdap booster. Adults over 30 are also not in the typical age group targeted for this specific booster, although they may receive Tdap for other clinical reasons, particularly if they are in contact with infants or pregnant women.
