An updated 2013 immunization schedule for children and adolescents also recommends pregnant adolescents receive the Tdap vaccine.

It says women should receive a vaccine for tetanus, diphtheria and pertussis, together known as Tdap, toward the end of pregnancy, or between 27 and 36 weeks' gestation.
Adults can replace a dose of their regular tetanus-and-diphtheria shot, given every 10 years, with Tdap, but don't have to wait out the 10 years, according to the CDC.
If it has been more than two years since a parent or caregiver had their last tetanus shot, the Tdap vaccine will be recommended now and again about every 10 years.
