ACIP Has Updated Its Recommendations on the Use of Tdap Vaccine in Pregnant Women and Children

At its October 2016 meeting, the Advisory Committee on Immunization Practices (ACIP) voted to update two of its recommendations for the use of Tdap vaccine (tetanus-, diphtheria-, pertussis-containing vaccine).

  1. For all pregnant women, Tdap vaccine is now recommended to be administered “early” in the 27- through 36-week gestational age window to maximize passive antibody transfer to the infant. Previously, the recommendation was to vaccinate women at any time between 27 and 36 weeks’ gestation.
  2. Children 7 to 10 years of age who receive a dose of Tdap as part of a catch-up series may be given an additional dose of Tdap for the routinely recommended adolescent dose at 11 to 12 years of age. Previously the recommendation was to not give an additional dose of Tdap at age 11 to 12 years in this situation.

Both recommendations are included in the 2017 U.S. immunization schedules, which means they are officially recommended by the Centers for Disease Control and Prevention (CDC).
