What is the recommended age range for administering the DPT vaccine?

The recommended age range for administering the DPT (Diphtheria, Pertussis, and Tetanus) vaccine is indeed within 6, 10, and 14 weeks. This schedule is part of a vaccination series that typically begins at 6 weeks of age to help protect infants from these serious diseases early in life. Administering the vaccine at these specific intervals allows the immune system to develop an adequate response to the vaccine components, ensuring that children receive the maximum possible benefit from the immunization in a timely manner.

The option that includes 4-6 weeks is too early for the initial DPT vaccine, as the immune system of infants at that age may not be fully capable of responding effectively to the vaccine. Similarly, while 12-15 months and 18 months are crucial times for additional doses of the DPT vaccine (booster doses), they do not represent the critical initial series recommended for early childhood immunization. Therefore, selecting the age range of 6, 10, and 14 weeks aligns with the established guidelines for optimal vaccination timing.
