Pentavalent vaccine is a combination of the following vaccine. Choose the right answer?

Appeared in: KPSC Staff Nurse - 2021

Explanation

The Pentavalent vaccine is a 5-in-1 combination vaccine that provides protection against five different life-threatening diseases.
Its components are Diphtheria, Pertussis (whooping cough), and Tetanus (often grouped as DPT), plus Hepatitis B (HepB) and Haemophilus influenzae type b (Hib).
This formulation simplifies the immunization schedule by combining multiple antigens into a single shot, which helps improve vaccination coverage and timeliness.

Option A: This option is incorrect as it includes Hepatitis A and influenza strains (H3N1, H3N2), which are not part of the standard Pentavalent vaccine.
Option B: This option incorrectly includes the pneumococcal vaccine and Inactivated Polio Vaccine (IPV).
Option C: This option is incorrect because it includes both the Inactivated Polio Vaccine (IPV) and the pneumococcal vaccine.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Composition of Pentavalent Vaccine as background academic context rather than a clinical decision trigger.
Understanding combination vaccines like Pentavalent is crucial for nurses to ensure adherence to the national immunization schedule and provide accurate information to parents.
Nurses must know the correct administration: 0.5 mL given intramuscularly (IM) in the anterolateral aspect of the mid-thigh for infants.
Common side effects include fever, irritability, and local pain/swelling. Nurses should advise parents on managing these with paracetamol and cold compresses.

How to Approach the Question

First, identify the key term in the question: 'Pentavalent vaccine'.
Recall the meaning of the prefix 'penta,' which means five. This tells you the vaccine combines protection against five diseases.
Systematically review the components listed in each option.
The standard Pentavalent vaccine in the Universal Immunization Programme (UIP) in India combines DPT (Diphtheria, Pertussis, Tetanus), Hepatitis B, and Haemophilus influenzae type b (Hib).
Eliminate options that include incorrect vaccines like Hepatitis A, influenza strains, pneumococcal vaccine, or IPV.
Select the option that correctly lists all five components: Diphtheria, pertussis, tetanus, hepatitis B, and Haemophilus influenza type B.
