Is it necessary to get vaccinated against rotavirus?
Generally, vaccination is recommended for children under 5 years of age and adult travelers going to areas where rotavirus is prevalent. However, healthy adults or individuals who have previously been infected with rotavirus and have recovered may not require vaccination. Detailed analysis is as follows:

Rotavirus is one of the primary causes of severe diarrhea in infants and young children, particularly common among children under 5 years old. Receiving the rotavirus vaccine can stimulate the body to develop immunity against rotavirus, thereby reducing the risk of infection. For adult travelers visiting regions where rotavirus is prevalent, vaccination can decrease the risk of infection and help protect both themselves and those around them.
The rotavirus vaccine primarily targets infants and young children who are more susceptible to rotavirus infection, especially those under 3 years of age. Therefore, healthy adults generally do not need the rotavirus vaccine unless in special circumstances. Individuals who have previously been infected with rotavirus and have recovered may have developed some immunity, resulting in a relatively lower risk of reinfection, and therefore also do not require vaccination.
When considering whether to receive the vaccine, it is recommended to consult with a healthcare professional to make an informed decision based on individual circumstances.
