Rotavirus disease is common among infants and young children. It can cause severe watery diarrhea, vomiting, fever and abdominal pain. Some children with rotavirus disease lose a lot of fluids, become very dehydrated and require hospitalization.
The virus passes through a sick person's stool and spreads when a child puts something with rotavirus on it, such as their hand or a toy, in their mouth. Children can also get infected by consuming food and liquids containing rotavirus.
Vaccination is the best way to protect your child. Almost all children who get the rotavirus vaccine (85 to 98 percent) will be protected from severe rotavirus disease. Most vaccinated children will not get it at all.
There are two different vaccines. Both are given by putting drops in an infant's mouth.
The first dose of either vaccine is most effective if given before a child is 15 weeks old. Children should receive all doses before they turn 8 months old.
