Rotavac vaccine is a monovalent, liquid, frozen vaccine given orally to prevent rotavirus gastroenteritis, a common cause of severe diarrhea in infants and young children. This vaccine uses a live, weakened (attenuated) rotavirus strain.
Key Characteristics of Rotavac Vaccine
Here's a breakdown of what makes Rotavac a unique vaccine:
- Type: Live attenuated oral vaccine
- Strain: Contains a specific rotavirus strain, 116E
- Production: Prepared in Vero cells
- Formulation: Liquid and frozen
- Dosage: Each 0.5 ml dose has at least 105.0 FFU (Fluorescent Focus Units) of live rotavirus 116E.
- Purpose: To prevent rotavirus gastroenteritis
How Rotavac Works
Rotavac works by introducing a weakened form of the rotavirus into the body. This triggers an immune response, allowing the body to develop antibodies that will protect against future infections from the wild-type rotavirus.
Additional Insights
- Administration: Since Rotavac is an oral vaccine, it is given as drops into the baby's mouth.
- Storage: The liquid vaccine is stored frozen to maintain its potency.
Who Should Receive Rotavac?
Rotavac is primarily intended for infants and young children, who are most susceptible to rotavirus infections.
