  • Tdap for Adolescents & Adults

If a teen or adult patient never received Tdap but received a dose of Td vaccine 2 years ago, should I wait 8 more years before administering a dose of Tdap to the patient?

No. ACIP recommends that people age 11 years and older who have not yet received Tdap receive a dose of Tdap now. ACIP specifies no waiting interval between administering Td and Tdap.
