Answer 1

Correct Answer: Three doses at one month intervals

Rationale:

DPT (Diphtheria, Pertussis, and Tetanus) vaccine is an essential part of the primary vaccination schedule for children. It provides immunity against three potentially serious bacterial infections.
In primary vaccination, DPT is administered in three doses at one-month intervals. This schedule ensures that the child develops adequate immunity over a relatively short period.
The first dose is typically given at 6 weeks of age, followed by the second dose at 10 weeks, and the third dose at 14 weeks. This timing aligns with the recommended immunization schedule by health authorities.

Explanation of Other Options:

Three doses at three month intervals

Rationale: Administering DPT at three-month intervals would delay the complete primary immunization process, leaving the child vulnerable to the diseases for a longer period. This is not the recommended schedule for primary vaccination.

Five doses at one month intervals

Rationale: While booster doses of DPT are given later in childhood, the primary vaccination consists of only three doses. Administering five doses in quick succession is unnecessary and not part of the standard immunization protocol.

Single dose

Rationale: A single dose of DPT is insufficient to build the necessary immunity against diphtheria, pertussis, and tetanus. Multiple doses are required to ensure adequate and long-lasting protection.

Conclusion:

The correct schedule for primary DPT vaccination involves administering three doses at one-month intervals. This ensures timely and effective immunization against these serious bacterial infections, following the recommended guidelines by health authorities.
