Is it necessary to take the oral rotavirus vaccine?

Oral rotavirus vaccine is used to prevent diarrhea caused by rotavirus infection and is an important component of health protection for infants and young children. Its necessity is reflected in the following aspects: 1. **Prevention of severe illness**: Rotavirus is the main pathogen causing diarrhea in infants and young children, easily leading to severe dehydration and even life-threatening conditions. The vaccine can effectively prevent the occurrence of severe illness. 2. **Symptom relief**: Even if infected, vaccination can alleviate symptoms of diarrhea, shorten the duration of illness, and reduce the risk of complications. 3. **Herd immunity**: Widespread vaccination helps establish a herd immunity barrier, reducing the risk of virus transmission. Please consult a doctor before vaccination to ensure your child receives the vaccine in a healthy condition. After vaccination, observe your child closely, and seek medical attention promptly if any adverse reactions occur.
