  • Tdap for Adolescents & Adults

Should I make an effort to give teenagers a Tdap dose, even if they’ve had a dose of Td at age 11–12 years?

Yes. All adolescents should receive one dose of Tdap vaccine to protect them from pertussis, even if they have already received Td. It is important to do this right away (no minimal interval is required), especially if they are in contact with an infant younger than age 12 months, work in a healthcare setting where they have direct contact with patients, or live in a community where pertussis is occurring.
