What Are the Side Effects of the Rotavirus Vaccine?
Oral rotavirus vaccine generally has no significant adverse reactions. However, due to individual constitution or other factors, some children may experience mild diarrhea, vomiting, low-grade fever, or rashes. Parents need not worry excessively—these unpleasant reactions typically resolve on their own within 2–3 days. Clinically, among children under five years old who receive the rotavirus vaccine, the following adverse symptoms have been observed: 1) After the first dose, low-grade fever, loss of appetite, irritability, and reduced activity are relatively common within five days. 2) After the second dose, only mild fever may occur as an adverse reaction. 3) The third dose usually causes no side effects or adverse reactions.
Rotavirus gastroenteritis primarily affects infants and young children under three years of age and is a serious threat to children's health. It peaks in prevalence during late autumn and early winter and is highly contagious. The virus spreads through close contact with infected individuals via the digestive and respiratory tracts, often leading to outbreaks. Clinical symptoms include fever, vomiting, abdominal pain, watery diarrhea, and sometimes concurrent respiratory infection symptoms.
Paying close attention to hygiene and taking protective measures for young children, along with enhancing their immunity and resistance, helps maintain good health and reduces the risk of various illnesses. We hope this information is helpful to you. Wishing you good health and a happy life!
