A 2014 review of available clinical trial data from countries routinely using rotavirus vaccines in their national immunization programs found that rotavirus vaccines have reduced rotavirus hospitalizations by 49–92% and all-cause diarrhea hospitalizations by 17–55%. Schedule
The World Health Organization recommends the first dose of vaccine be given right after six weeks of age. Types
Rotarix
Rotarix is a monovalent, human, live attenuated rotavirus vaccine containing one rotavirus strain of G1P[8] specificity. Rotarix is indicated for the prevention of rotavirus gastroenteritis caused by G1 and non-G1 types (G3, G4, and G9) when administered as a 2-dose series in infants and children. It was approved in Europe in 2006 and by the U.S. FDA in April 2008. It is administered by mouth. RotaTeq
RotaTeq is a live, oral pentavalent vaccine that contains five rotavirus strains produced by reassortment. The rotavirus A parent strains of the reassortants were isolated from human and bovine hosts. Four reassortant rotaviruses express one of the outer capsid, VP7, proteins (serotypes G1, G2, G3, or G4) from the human rotavirus parent strain and the attachment protein VP4 (type P7) from the bovine rotavirus parent strain. The fifth reassortant virus expresses the attachment protein VP4, (type P1A), from the human rotavirus parent strain and the outer capsid protein VP7 (serotype G6) from the bovine rotavirus parent strain. In February 2006, the U.S. Food and Drug Administration approved RotaTeq for use in the United States. In August 2006, Health Canada approved RotaTeq for use in Canada.
At US$5 per dose, the estimated cost per life saved was $3,015, $9,951 and $11,296 in low-, lower-middle-, and upper-middle-income countries, respectively.Safety and efficacy trials in Africa and Asia found that the vaccines dramatically reduced severe disease among infants in developing countries, where a majority of rotavirus-related deaths occur. A 2019 Cochrane review concluded that RV1, RV5, and Rotavac vaccines are safe and are effective at preventing diarrhea.Rotavirus vaccines are licensed in more than 100 countries, and more than 80 countries have introduced routine rotavirus vaccination. The incidence and severity of rotavirus infections has declined significantly in countries that have acted on the recommendation to introduce the rotavirus vaccine. In Mexico, which in 2006 was among the first countries in the world to introduce rotavirus vaccine, the diarrheal disease death rates from rotavirus dropped by more than 65% among children age two and under during the 2009 rotavirus season. In Nicaragua, which in 2006 became the first developing country to introduce the rotavirus vaccine, investigators recorded a substantial impact, with rotavirus vaccine preventing 60% of cases against severe rotavirus and cutting emergency room visits in half. In the United States, vaccination has reduced rotavirus-related hospitalizations by as much as 86% since 2006. In April 2016, the World Health Organization released statistics for the period of 2000–2013, which showed developing countries that have introduced rotavirus vaccines experienced significant decreases in deaths and hospitalizations from rotavirus diarrhea after introduction.Additionally, the vaccines may also prevent illness in non-vaccinated children by limiting exposure through the number of circulating infections.
