When should adolescents who received a dose of Tdap (Adacel, Sanofi; Boostrix, GSK) at age 11–12 years receive their next dose of Td or Tdap?

As of January 2020, ACIP recommends that Td or Tdap may be administered in any situation when only Td vaccine was previously recommended. Someone who received a dose of Tdap at age 11 or 12 years should receive a booster dose of Td or Tdap vaccine ten years later, unless tetanus prophylaxis is required sooner due to an injury or if Tdap vaccination is needed during pregnancy.
