How should Rotarix (RV1) be administered?

Rotarix (RV1) is administered as a 2-dose oral series with the first dose given at 2 months of age and the second dose at 4 months of age. This dosing schedule aligns with recommendations to ensure effective immunity against rotavirus infection, which is a leading cause of severe gastroenteritis in infants and young children.

The first dose at 2 months allows the infant’s immune system to begin responding to the vaccine, while the second dose at 4 months enhances the immune response and provides optimal protection. Following this regimen is critical, as it has been shown to improve vaccine efficacy and reduce the risk of rotavirus-related hospitalizations and complications.

Timing and the proper number of doses are essential because administering the vaccine too early or not adhering to the schedule could compromise its effectiveness. Therefore, the 2-dose oral series approach for Rotarix is the recommended method for safe and effective immunization against rotavirus.
