This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.

Background and Date of Approval

The U.S. Food and Drug Administration (FDA) initially approved the Rotavirus vaccine on  April 3, 2008.

Mechanism of Action of undefined

Rotavirus vaccines work by introducing weakened forms of the virus into the body. These weakened strains stimulate the immune system to produce protective antibodies without causing the disease. If a vaccinated individual is later exposed to the rotavirus, their immune system recognizes and fights it, preventing severe diarrhea and related complications.

Uses of undefined

Rotavirus vaccines prevent rotavirus infection in pediatric healthcare in infants and young children. These vaccines effectively reduce the severity and duration of diarrhea and vomiting, which can lead to dehydration and hospitalization. They contribute to public health by lowering the overall incidence of rotavirus infections, improving child health, and supporting global health initiatives. Additionally, they establish herd immunity, protecting vulnerable populations.

undefined Drug administaration and Dosage available

Rotavirus vaccine is administered orally in liquid drops or using an oral syringe. This mode of administration is well-suited for infants and young children and involves giving the vaccine by mouth. The vaccines are typically given at specific intervals, following a recommended dosing schedule, to ensure optimal protection.

Warnings, Precautions and Side Effects of undefined


While the risk is extremely low, there is a potential association between rotavirus vaccines and intussusception, a rare intestinal condition where one part of the intestine telescopes into another. Severe allergic reactions (anaphylaxis) to vaccine components are rare but possible. Certain medical conditions, such as severe immunodeficiency disorders or a history of intussusception, may require special precautions.


Parents and caregivers should be aware of the signs and symptoms of intussusception, such as severe abdominal pain, vomiting, and bloody stools, and seek immediate medical attention if these symptoms occur after taking rotavirus. Individuals with known allergies to specific vaccine ingredients should inform their healthcare provider before vaccination.  Some medical conditions, such as severe immunodeficiency disorders, a history of intussusception, or known allergies to vaccine components, may require special precautions or considerations before vaccination.

Side Effects

Rotavirus vaccines typically have mild and temporary side effects. Common side effects can include irritability, mild diarrhea or vomiting, low-grade fever, and soreness at the injection site (for Rotarix, oral administration). Serious side effects are rare but can include a very low risk of intussusception, a rare intestinal condition, particularly after the first dose. Severe allergic reactions (anaphylaxis) are also extremely rare. 

Word Of Advice

After taking the Rotavirus vaccine, evaluate individuals with moderate to severe acute illnesses, a history of gastrointestinal disorders, previous intussusception, severe immunodeficiency disorders, known allergies to vaccine components, households with immunocompromised members, and those with special medical conditions. Additionally, premature infants and individuals who have experienced significant adverse reactions to previous vaccine doses may warrant specific precautions. It's crucial to adhere to recommended age and dosing schedules, maintain vaccine brand consistency throughout the series, and follow proper storage and handling guidelines. Open communication with healthcare professionals is essential to address any concerns or questions about vaccination precautions effectively and to ensure this vaccine's safe and effective use.
