Vaccines your family may need

There are three types of combination vaccines that protect against diphtheria: DTaP, Tdap, and Td.

Babies and children younger than 7 years old receive DTaP, while older children and adults receive Tdap and Td.

Babies and children

Babies

Babies need 3 shots of DTaP to build up high levels of protection against diphtheria. CDC recommends these shots at the following ages:

  • 2 months
  • 4 months
  • 6 months

Children

Children need 2 booster shots of DTaP at the following ages to maintain that protection through early childhood:

  • 15 through 18 months
  • 4 through 6 years

Preteens and teens

Preteens should get one shot of Tdap between the ages of 11 and 12 years to boost their immunity. Teens who didn’t get Tdap as a preteen should get one shot the next time they visit their healthcare provider.

Adults

To maintain protection, CDC recommends all adults get vaccinated against diphtheria every 10 years. Once an adult has received a dose of Tdap, they can get Td or Tdap for their booster doses

Tdap vaccination during pregnancy‎‎

CDC recommends women get Tdap during the early part of the 3rd trimester of every pregnancy. While Tdap also helps protect against tetanus and diphtheria, the main goal is to protect babies from whooping cough in the first few months of life.
