Pentavalent vaccine is given at

Appeared in: Tripura CHO - 2021

Explanation

The Pentavalent vaccine is administered as a three-dose primary series at 6, 10, and 14 weeks of age.
This schedule is recommended by the National Immunization Schedule (NIS) in India to provide timely protection against five major diseases.
The schedule involves giving the first dose at 6 weeks, followed by the second and third doses at intervals of 4 weeks each.
Administering the vaccine at these specific ages ensures the infant builds immunity as the protection from maternal antibodies decreases.

Option A: The schedule of 4, 8, and 12 weeks is not the standard for the Pentavalent vaccine under the Indian National Immunization Schedule (NIS).
Option B: The schedule of 5, 10, and 15 weeks is incorrect. The intervals between doses are not standard, and the start time is not aligned with the NIS.
Option D: The schedule of 4, 8, and 16 weeks is incorrect. The interval between the second and third doses (8 weeks) is too long for the primary series of the Pentavalent vaccine.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Immunization schedule for Pentavalent vaccine as per the National Immunization Schedule (NIS) of India as background academic context rather than a clinical decision trigger.
Adherence to the 6, 10, 14-week schedule is critical for public health, as it ensures infants are protected from five life-threatening diseases before they are most vulnerable.
As a nurse, it is essential to educate parents on the importance of completing the full three-dose series on time to ensure their child develops adequate immunity.
Combination vaccines like Pentavalent are a key strategy to improve vaccination coverage by reducing the number of injections, which in turn decreases infant distress and increases parental compliance.

How to Approach the Question

First, identify the core of the question, which is asking for the specific administration schedule of the Pentavalent vaccine.
Recognize that this is a factual recall question based on a standardized public health program.
Recall the National Immunization Schedule (NIS) for India, which is the standard for government-provided vaccinations.
Systematically compare each option with the known NIS schedule.
The NIS clearly states three doses of Pentavalent vaccine are given at 6, 10, and 14 weeks of age.
Select the option that perfectly matches this official schedule.
