Rotarix Vaccine Description
GSK's Rotarix is a live, attenuated rotavirus vaccine derived from the human 89-12 strain, which belongs to the G1P type. This rotavirus strain is propagated on Vero cells. After reconstitution, the final formulation (1 mL) contains at least 106.0 median Cell Culture Infective Dose (CCID50) of live, attenuated rotavirus.
Rotarix vaccine is used to help prevent disease in children. Rotarix works by exposing your child to a small dose of the virus, which causes the body to develop immunity to the disease. However, this vaccine will not treat an active infection that has already developed in the body.
The global clinical development program spanned five continents and demonstrates that Rotarix protects against the most common circulating strains (G1 and non-G1 rotavirus strains), including the emerging G9 strain.

Rotarix Vaccine Indication
Rotarix is a vaccine indicated for preventing rotavirus gastroenteritis caused by G1 and non-G1 types (G3, G4, and G9) when administered as a 2-dose series. ROTARIX is approved for use in infants 6 weeks to 24 weeks of age.
Rotavirus spreads easily among infants and young children. The virus can cause severe watery diarrhea, vomiting, fever, and abdominal pain. Children who get rotavirus disease can become dehydrated and may need to be hospitalized. The U.S. CDC recommends that infants get the rotavirus vaccine to protect against rotavirus disease. Rotarix is also able to reduce hospitalizations for all gastroenteritis, regardless of cause.
Rotarix Vaccine Dosage
The vaccination series consists of two 1-mL doses administered orally. The first dose should be administered to infants beginning at 6 weeks of age. There should be an interval of at least 4 weeks between the first and second dose, and the 2-dose series should be completed by 24 weeks of age.
What if my baby spits out the vaccine or vomits immediately after having it? The oral vaccine will be given again. Do not worry about overdosing. Even if some of the vaccine was swallowed the first time, there's no harm in having 2 doses at the same time, says the UK's NHS.

The WHO prequalification will accelerate access to the vaccine in Asia and Africa and expands on the WHO decision taken in 2007 to prequalify the vaccine for Europe and the Americas. The WHO prequalification is necessary for UN agencies and the GAVI Alliance to purchase rotavirus vaccines on behalf of developing countries.
