The CDC recommends the Tdap vaccine for all adults ages 19 and older who have never received the vaccine, especially:
- Health care workers who have direct contact with patients
- Caregivers of infants under 1 year old, including parents, grandparents, and babysitters
- Pregnant women in their third trimester (ideally 27th through 36th week), even if they have previously received Tdap vaccine; this can protect a newborn from whooping cough in the first months of life.
- New mothers who have never received the Tdap
- People who travel to countries where pertussis is common
