Rotavirus is a highly contagious virus that can cause severe diarrhea and vomiting in infants and young children. Although it is rarely fatal, it can be very uncomfortable and lead to dehydration if not treated promptly. Fortunately, the rotavirus vaccine has become available in recent years, providing protection against this virus for young children. The rotavirus vaccine is highly effective at preventing severe cases of rotavirus disease and has been shown to reduce hospitalizations due to rotavirus by up to 98%. This makes it an important tool for protecting young children from the effects of this virus.
