If there is no documentation of a pregnant person ever receiving Td or Tdap, what schedule should we follow?

The recommended schedule for the primary series given to an unvaccinated person is dose 1 now, dose 2 in 4 weeks, and dose 3 in 6 to 12 months. Tdap should replace at least 1 dose of Td, preferably between 27 and 36 weeks’ gestation to maximize the maternal antibody response and passive antibody transfer to the infant.
