Vaccine to control diarrhoea is?

Appeared in: Tripura CHO - 2021

Explanation

Rotavirus is the leading cause of severe, dehydrating diarrhea in infants and young children globally.
The Rotavirus vaccine is a live, attenuated oral vaccine specifically designed to prevent gastroenteritis caused by rotavirus infection.
It works by stimulating the immune system to build protection against the virus, significantly reducing the incidence of severe diarrhea and related hospitalizations.
The vaccine is a key public health intervention to reduce childhood morbidity and mortality from diarrheal diseases.

Option A: The Pneumococcal vaccine targets Streptococcus pneumoniae bacteria.
Option C: The Salk vaccine is the Inactivated Polio Vaccine (IPV).
Option D: The HIB vaccine targets the Haemophilus influenzae type b bacterium.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Indications for common childhood vaccines as background academic context rather than a clinical decision trigger.
The introduction of the Rotavirus vaccine into national immunization programs, like in India, has drastically reduced hospitalizations and deaths due to severe childhood diarrhea.
Nurses play a critical role in educating parents about the vaccine schedule, the importance of completing the doses, and managing mild post-vaccination side effects, which improves vaccine compliance and public health outcomes.
What if? If an infant presents with a history of intussusception (a condition where the intestine telescopes into itself), the Rotavirus vaccine is contraindicated. The nurse must screen for this history before administration.

How to Approach the Question

First, read the question carefully to identify the core concept being tested: a vaccine for controlling diarrhea.
Next, review each option and recall the primary disease it is designed to prevent.
Option A, Pneumococcal, is for respiratory and invasive bacterial infections.
Option B, Rotavirus, is known to be associated with gastroenteritis.
Option C, Salk, is for polio.
Option D, HIB, is for other specific bacterial infections.
