Explanation

According to the National Immunization Schedule (NIS) in India, the first (birth) dose of the Hepatitis B vaccine is administered at birth.
This dose should be given as early as possible, preferably within 24 hours of birth.
The primary reason for the birth dose is to prevent perinatal (mother-to-child) transmission of the Hepatitis B virus, which is a significant mode of transmission.
Early vaccination also protects the infant from horizontal transmission (from other infected individuals) during early childhood.

Option B: 4 months is not the time for the first dose of the HBV vaccine. The primary series under the NIS is typically completed by 14 weeks.
Option C: The NIS schedule for the HBV vaccine includes a dose at 10 weeks as part of the Pentavalent vaccine, but this is the second dose, not the first.
Option D: 15 months is incorrect for the first dose of HBV. This age is typically associated with booster doses for other vaccines like MMR and DPT.

Clinical Relevance

Nursing practice connection: Use the key finding related to National Immunization Schedule (NIS) for Hepatitis B vaccine to guide bedside assessment, documentation, and the next nursing action.
Nurses are at the forefront of implementing the National Immunization Schedule. They are responsible for administering vaccines correctly, maintaining the cold chain, and educating parents on the schedule and potential side effects.
Accurate documentation on the immunization card is a critical nursing responsibility. It serves as a legal record and ensures the child receives all doses at the appropriate time.
What if? If an infant is born to a mother who is a known HBsAg-positive carrier, the infant must receive both the Hepatitis B vaccine and Hepatitis B Immune Globulin (HBIG) within 12-24 hours of birth at different injection sites to provide immediate passive and active immunity.

How to Approach the Question

This is a factual recall question based on the National Immunization Schedule (NIS).
Identify the key phrase in the question: "first dose" of "HBV vaccine".
Recall the standard list of vaccines administered immediately after birth in India.
The at-birth vaccines are BCG, Oral Polio Vaccine (OPV-0), and the birth dose of Hepatitis B.
This knowledge directly points to "At birth" as the correct answer.
Eliminate the other options as they correspond to timings for subsequent doses or different vaccines within the infant immunization schedule.
