How old must a baby be to receive the first dose of the pentavalent rotavirus vaccine?

The pentavalent rotavirus vaccine, commonly referred to as "pentavalent rotavirus," does not require the first dose to be administered at a specific age. However, it is recommended that the initial doses be completed between 6 and 12 weeks of age, preferably before 3 months of age.

The pentavalent rotavirus vaccine is designed to prevent rotavirus enteritis and is primarily intended for children aged 2 months to 3 years. Rotavirus infection, which mainly occurs in late autumn and early winter, is highly contagious. Both symptomatic patients and asymptomatic carriers serve as sources of infection, spreading the virus via the fecal-oral route, close contact, and respiratory droplets. Ensuring timely vaccination can effectively protect infants against rotavirus. The claim that "the first dose of the pentavalent rotavirus vaccine must be given at a certain age" is inaccurate. While individual differences may exist in vaccination schedules, it is generally recommended that the first dose be administered between 6 and 12 weeks of age (before 3 months), the second dose between 10 and 22 weeks, and the third dose between 14 and 32 weeks of age. All three doses should be completed within 8 months, with at least 4 weeks between each dose. Following this schedule typically achieves optimal immunization results.

It should be noted that if mild reactions such as low-grade fever, vomiting, or diarrhea occur after vaccination, parents need not be concerned. Encourage the child to drink plenty of warm water and ensure adequate rest.
