What is the schedule for the DTaP vaccine?

The DTaP vaccine schedule is accurately described by the choice that lists administration at 2 months, 4 months, 6 months, followed by doses at 15 to 18 months and again at 4 to 6 years of age. This schedule is established to provide optimal immunity against diphtheria, tetanus, and pertussis during early childhood, as well as to ensure that children maintain adequate protection as they grow.

The initial doses (2m, 4m, and 6m) help build strong immunity within the first year of life when infants are most vulnerable to these diseases. The booster doses given at 15 to 18 months and again at 4 to 6 years are critical to reinforce immunity as it begins to wane and to protect the child as they encounter these pathogens in the environment.

While other options may list certain doses, they do not present the complete and recommended schedule for the DTaP vaccine. This comprehensive schedule ensures that children receive the full range of immunizations needed to protect against serious diseases.
