ACIP recommends the following:
- All adults age 19 years and older who have not yet received a dose of Tdap should receive a dose.
- All pregnant people should receive a dose of Tdap during each pregnancy, preferably between 27 and 36 weeks’ gestation. Mothers who have never received Tdap and who do not receive it during pregnancy should receive it immediately postpartum.
- A person who has not yet received a dose of Tdap can be given a dose of Tdap regardless of the interval since the person last received a tetanus or diphtheria toxoid-containing vaccine.
- Providers should not miss an opportunity to vaccinate adults age 65 years and older with Tdap. When feasible, give Boostrix to adults age 65 and older. However, either vaccine product (Adacel or Boostrix) provides protection and is considered valid for use in people in this age group.
- For adults not previously vaccinated with Tdap who need wound management care to prevent tetanus, Tdap is preferred over Td.
- For adults who have received an initial dose of Tdap, Tdap may be administered in any situations where Td only was previously recommended, including as the decennial (every 10-years) booster dose.
