After what age should the BCG vaccine not be administered?

Appeared in: MP CHO -2019 (Shift-1)

Explanation

According to India's National Immunization Schedule (NIS), the BCG vaccine is recommended at birth or as early as possible, but only up to 1 year of age.
Administering the vaccine after the age of one is not standard practice because its protective efficacy against tuberculosis is considered to be significantly reduced.
The likelihood of developing more pronounced local reactions, such as swelling of the lymph nodes in the armpit (suppurative lymphadenitis), increases in children vaccinated after infancy.

Option A: This is incorrect. If a child misses the BCG vaccine at birth, it can be given at any time up to the age of 1 year.
Option C: This is incorrect. Administering the BCG vaccine after 1 year of age is not recommended under the national schedule due to reduced benefits.
Option D: This is incorrect. This age is well beyond the recommended window for BCG vaccination, where its utility is considered doubtful.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain The concept tested is the knowledge of the upper age limit for the administration of the BCG vaccine as per the National Immunization Schedule in India as background academic context rather than a clinical decision trigger.
A nurse's primary responsibility is to adhere strictly to the National Immunization Schedule to ensure patient safety and vaccine efficacy.
Before administering the BCG vaccine, the nurse must confirm the child's age. If the child is over one year old, the vaccine should be withheld, and the parents should be counseled appropriately.
What if? If a 14-month-old child is brought for immunization and has no record or scar of a BCG vaccine, the nurse should not administer it. The correct action is to inform the parents that the window for routine BCG vaccination has passed and proceed with other age-appropriate vaccines.

How to Approach the Question

First, identify the key subject of the question, which is the 'BCG vaccine'.
Next, recognize that the question is asking for a specific guideline: the upper age limit for administration ('after what age... not be administered').
This is a factual recall question that relies on knowledge of the National Immunization Schedule.
Recall or deduce that BCG is given at birth or very early in life.
Evaluate the options. The standard cut-off for catch-up BCG vaccination in India is 1 year. Options like 2 and 5 years are too late, and 6 months is within the acceptable period.
