  • Who should get the Tdap vaccine? Who should get the DTaP vaccine?

    Tdap and DTaP are vaccines that can help protect against three serious diseases: tetanus, diphtheria, and pertussis (whooping cough). The Centers for Disease Control and Prevention (CDC) recommends that adults age 19 or older who never received a dose of Tdap should get one. After the first dose, adults should receive Td or Tdap as a booster shot every 10 years. The CDC recommends that pregnant people receive a Tdap vaccine with every pregnancy between the 27th and 36th week, preferably in the early part of this time frame, although it could be administered at any time during pregnancy. DTaP is recommended for very young children, and Tdap is recommended for older children, adolescents, pregnant people, and adults. Talk to your doctor or pharmacist to learn more about whooping cough vaccination and when it is recommended.
