How Long Do Rotavirus Vaccine Side Effects Last?

The oral rotavirus vaccine is used to prevent group A rotavirus diarrhea in infants and young children. It is mainly recommended for children aged 2 months to 3 years, with annual vaccination advised. After taking the vaccine, brief mild vomiting or diarrhea may occur, which usually resolves spontaneously within 2–3 days. Within 1–2 weeks, temporary fever reactions may also occur. Drink plenty of water, keep warm, and if body temperature exceeds 38.5°C, antipyretics can be taken as needed. Medications for diarrhea may also be used.


There are differences between the oral rotavirus vaccine and the pentavalent rotavirus vaccine. First, the conventional oral rotavirus vaccine targets children aged 2 to 36 months. Taking this vaccine helps generate immunity and prevents diarrhea caused by this type of virus in infants and young children. The pentavalent rotavirus vaccine is an oral live-attenuated vaccine that protects against five strains of rotavirus, administered in three doses. It differs from the conventional vaccine in terms of target population, protection rate, and duration of protection. Second, the conventional oral rotavirus vaccine has an overall protection rate of 73.72%, with over 90% protection against severe diarrhea, and provides protection for about 1 year. In contrast, the pentavalent rotavirus vaccine offers up to 95.5% protection against five strains of the virus and provides long-lasting immunity for up to 7 years. Third, the conventional oral rotavirus vaccine is provided free of charge, while the pentavalent rotavirus vaccine requires out-of-pocket payment.

Can I take probiotics after taking the oral pentavalent rotavirus vaccine?
Whether probiotics can be taken after oral administration of the pentavalent rotavirus vaccine depends on the timing and physical condition. If a certain interval has passed and no discomfort occurs, probiotics can be taken normally. However, if the vaccine was just administered or gastrointestinal discomfort is present, it is advisable to delay taking probiotics. Maintain a light diet before and after taking the oral vaccine, and avoid spicy, raw, or cold foods. Probiotics should be taken with lukewarm water to prevent the active components from being destroyed by high temperatures.
