Can the pentavalent rotavirus vaccine be delayed by a few days?

The pentavalent rotavirus vaccine usually refers to the pentavalent reassortant rotavirus attenuated live vaccine, which can generally be delayed by up to 30 days. The detailed explanation is as follows:

After administration of the pentavalent reassortant rotavirus attenuated live vaccine, immunity is typically stimulated in the body, protecting infants and young children against gastroenteritis caused by five serotypes of rotavirus—G1, G2, G3, G4, and G9. Usually, three doses are required. If a child is unwell during the scheduled appointment, vaccination may be postponed, but the delay should not exceed 30 days. Excessively prolonging the interval may reduce the vaccine's protective effect or interfere with subsequent vaccinations.

If rotavirus infection occurs, patients are advised to actively seek proper medical treatment under a doctor’s guidance to prevent severe diarrhea from adversely affecting health.
