One dose of Tdap vaccine is recommended for: 1  Kids aged 7 to 10 years who who did not get all 5 doses of DTaP vaccine. 2  Adolescents aged 11 to 18 years (preferably at 11 or 12 years of age). 3  Pregnant women need to get Tdap vaccine at each pregnancy, even if they've been vaccinated before.
Tetanus, diphtheria, and pertussis (Tdap) vaccine should be given during each pregnancy irrespective of the womanâs history of receiving Tdap. To maximize maternal antibody response and passive antibody transfer to the infant, optimal timing for Tdap administration is between 27 and 36 weeks of gestation, although it may be given at any time during pregnancy.
