What are the recommendations for use of rotavirus vaccines?

Two rotavirus vaccines are available in the United States. RotaTeq (RV5; Merck) is recommended for routine oral administration for all infants as a 3-dose series. The usual schedule is at ages 2, 4, and 6 months. Rotarix (RV1; GlaxoSmithKline) is recommended as a 2-dose series at ages 2 and 4 months.

The minimum interval between doses of rotavirus vaccine is 4 weeks. The minimum age for the first dose is 6 weeks and the maximum age for dose #1 is 14 weeks 6 days. Vaccination should not be initiated for infants age 15 weeks 0 days or older because there are insufficient data on the safety of dose #1 in older infants. The maximum age for the last dose of rotavirus vaccine is 8 months and 0 days.
