At what age should the Rotavirus vaccine series start?

The Rotavirus vaccine series should start at 6 weeks of age. This timing is crucial as it aligns with the period when infants are most vulnerable to severe gastroenteritis caused by rotavirus. Starting the vaccination early helps provide protection before many infants are likely to be exposed to the virus, particularly during the rotavirus season.

The vaccine series typically includes multiple doses, with the first dose given between 6 weeks and 15 weeks of age, ensuring that children receive optimal immunity as they grow. Vaccinating at this age not only contributes to the individual child’s health but also helps in reducing the overall incidence of rotavirus infection in the community, protecting those who may be more vulnerable.

In contrast, waiting until 12 months, 1 year, or 3 months would miss the early window where vaccination is most beneficial, leading to an increased risk of severe disease.
