When is the first dose of Hepatitis-B given?

Appeared in: MP CHO -2021 (Shift 1st)

Explanation

'At Birth' as per the National Immunization Schedule (NIS) in India.
This initial dose, known as the birth dose, should be administered ideally within 24 hours of life.
The primary purpose of the birth dose is to prevent perinatal transmission of the Hepatitis B virus from an infected mother to her newborn.
Even if the mother's Hepatitis B status is unknown, the birth dose is recommended to prevent potential horizontal transmission.

Option B: 14 weeks is the timing for the third primary dose of the Hepatitis B vaccine, which is administered as part of the Pentavalent vaccine combination.
Option C: While a 0, 1, and 6-month schedule exists, it is typically an alternative schedule used for older children, adolescents, or adults, not the standard for the first dose in newborns under the national program.
Option D: 9 months is the standard age for administering the first dose of the Measles-Rubella (MR) or Measles, Mumps, and Rubella (MMR) vaccine.

Clinical Relevance

Nursing practice connection: Knowing Infant Immunization Schedule: Hepatitis B Vaccine Timing helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses play a critical role in ensuring all newborns receive their Hepatitis B birth dose within the 24-hour window, a key public health intervention.
It is a crucial nursing responsibility to identify infants born to HBsAg-positive mothers and ensure they receive both the vaccine and Hepatitis B Immune Globulin (HBIG) promptly to prevent chronic infection.
Patient education is vital. Nurses must educate new mothers about the importance of the vaccination schedule to ensure compliance for subsequent doses and protect the child's long-term health.

How to Approach the Question

This is a factual recall question based on established medical guidelines.
Identify the core of the question: the timing of the first dose of the Hepatitis B vaccine.
Access your knowledge of the National Immunization Schedule (NIS) for infants.
Recall that Hepatitis B is one of the vaccines given right at birth.
Evaluate the options: 'At Birth' directly matches the NIS. The other options (14 weeks, 6 months, 9 months) correspond to other vaccine doses or different vaccines entirely.
Select 'At Birth' as the only correct timing for the initial dose.
