Administration of Rotavirus Vaccine
The rotavirus vaccine is part of the recommended vaccination schedule for children Childhood Vaccination Schedule Most doctors follow the vaccination schedule recommended by the Centers for Disease Control and Prevention (CDC—see the schedule for infants and children and the schedule for older children... read more . This vaccine is given by mouth. Two or three doses are given, depending on the formulation: at age 2 months and 4 months or at 2 months, 4 months, and 6 months.
People who have had serious allergic reactions to a previous dose of the vaccine or to a vaccine component should not be given the rotavirus vaccine.
Certain conditions may affect whether and when people are vaccinated (see also CDC: Who Should NOT Get Vaccinated With These Vaccines?). For example, rotavirus vaccine should not be given to infants who have certain immunodeficiency disorders Severe Combined Immunodeficiency (SCID) Severe combined immunodeficiency is a primary immunodeficiency disorder resulting in low levels of antibodies (immunoglobulins) and low or no T cells (lymphocytes).

Side Effects of Rotavirus Vaccine
Infants may have mild, temporary diarrhea or vomiting. They may become irritable.
When an older rotavirus vaccine was used, the risk of intussusception was increased. In intussusception, the intestine is blocked because one segment of the intestine slides into another, much like the parts of a telescope. The older vaccine was taken off the market in the United States. The newer vaccines, when given as recommended, may increase the risk of intussusception but only slightly.
