DTP Vaccines

Diphtheria, tetanus, and pertussis were among the first vaccines that were developed:

  • diphtheria vaccine – 1888
  • first tetanus vaccine – 1914
  • first pertussis vaccine – 1915

It wasn’t until 1949 that they were improved and combined into the DTP vaccine though.

A separate Td vaccine was licensed for adults in 1953.

Today, all children get their first dose of the latest DTaP vaccines when they are two months old, completely a three dose primary series by the time they are six months old. Children get booster doses of DTaP when they are 15 to 18 months old and again at age four to six years.

A Tdap booster is given at age 11 to 12 years.
