At what ages should the DTaP vaccine be administered?

The DTaP vaccine, which protects against diphtheria, tetanus, and pertussis, is typically administered in a series during infancy and early childhood. The recommended schedule includes administering the first dose at 2 months of age, followed by doses at 4 months and 6 months. This schedule is designed to provide early protection as infants are particularly vulnerable to these diseases.

The vaccine is generally given in a series of five doses, with the earlier doses crucial for building immunity as the child grows. While other ages mentioned in the options may include doses for other vaccines or additional recommended doses, the established guideline for the primary series of the DTaP is indeed at 2, 4, and 6 months of age. This reflects the current vaccine schedule endorsed by health authorities.
