Rotavirus Vaccine (live Attenuated,oral)

Introduction

Rotavirus vaccine (live attenuated, oral) is a preventive vaccine administered to infants to protect against rotavirus infections. Rotavirus is a highly contagious virus that causes severe diarrhea, vomiting, and fever in children, often leading to dehydration. This oral vaccine is made from weakened strains of the live virus, designed to help the body build immunity without causing the illness. Early vaccination is crucial in reducing hospitalizations and complications related to rotavirus. The vaccine is given orally in multiple doses starting at 6 weeks of age and plays a significant role in child healthcare and disease prevention worldwide.

Uses of Rotavirus Vaccine (Live Attenuated, Oral)

• Prevention of rotavirus gastroenteritis in infants and young children

How Rotavirus Vaccine (Live Attenuated, Oral) Works

The vaccine contains weakened (attenuated) live rotavirus strains that stimulate the immune system to develop protection without causing illness. When administered orally, the body recognizes the virus and produces antibodies, which help the immune system respond effectively if exposed to the real virus later in life. This immunity helps prevent future rotavirus infections or reduces their severity.
