My 11-year-old patient received a dose of Tdap when he was 7 years old. He also received a dose of Td 6 months later in order to finish a primary series of tetanus-toxoid. Can I give him a dose of Tdap now?

Yes. The January 2020 ACIP updated statement on the use of Tdap (available at www.cdc.gov/mmwr/volumes/69/wr/pdfs/mm6903a5-H.pdf) states that a child who receives a dose of Tdap from age 7–9 years as part of the catch-up series (as in this case), should receive another dose of Tdap at age 11 or 12 years.
