Explanation

The Pentavalent vaccine is a 5-in-1 combination vaccine given to infants.
It contains components for Diphtheria, Pertussis, Tetanus (DPT), Hepatitis B, and Haemophilus influenzae type b (Hib).
The Hib component specifically provides protection against invasive diseases caused by this bacterium, including pneumonia and meningitis.
Therefore, among the choices provided, the Pentavalent vaccine is used to prevent a specific type of bacterial pneumonia in infancy.

Option B: The Rotavirus vaccine is designed to protect against rotavirus, which is the most common cause of severe diarrheal disease in infants and young children. It does not offer protection against respiratory infections like pneumonia.
Option C: This option is incorrect because only Pentavalent (Option A) prevents pneumonia. Rotavirus (Option B) does not.
Option D: This option is incorrect because the Pentavalent vaccine does provide protection against a significant cause of pneumonia in infants (Haemophilus influenzae type b).

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Childhood immunization and prevention of pneumonia as background academic context rather than a clinical decision trigger.
Nurses play a vital role in administering vaccines according to the National Immunization Schedule and educating parents on the importance of each vaccine, the diseases they prevent, and potential side effects.
Understanding combination vaccines like Pentavalent is crucial for explaining to parents how their child receives protection against multiple serious diseases with fewer injections, improving compliance and comfort.
What if a parent asks if the Pentavalent vaccine is the only 'pneumonia shot'? The nurse should explain that while Pentavalent protects against Hib pneumonia, the separate PCV (Pneumococcal) vaccine is also critical to protect against another common and serious type of pneumonia.

How to Approach the Question

First, identify the key concept in the question: a vaccine that prevents 'pneumonia' in 'infancy'.
Recall the common vaccines given to infants and the primary diseases they target.
Evaluate Option A (Pentavalent): Remember it's a 5-in-1 vaccine. What are the five components? DPT, HepB, and Hib. Does Hib cause pneumonia? Yes. So, this is a strong candidate.
Evaluate Option B (Rotavirus): What does this vaccine prevent? Severe diarrhea. This does not match the question's requirement for pneumonia prevention.
Based on the evaluation, eliminate Option B, which also automatically eliminates Option C ('Both A&B').
Since Option A is a valid answer, Option D ('None') is also incorrect. This leaves Option A as the only correct choice.
