WHO recommendations for routine immunization - summary tables (January 2025)
WHO recommends that the first dose of rotavirus vaccine be administered as soon as possible after 6 weeks of age. A minimum interval of 4 weeks should be maintained between doses. Note: The rotavirus vaccination series for each child should be completed with the same product whenever feasible. However, if the product used for a prior dose is unavailable or unknown, the series should be completed with any available licensed product.
