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.
Temporary suspension in the US
On March 22, 2010, the detection of DNA from porcine circovirus types 1 and 2 within RotaTeq and Rotarix prompted the FDA to suspend the use of rotavirus vaccines while conducting an investigation the finding of DNA from porcine circovirus-1 (PCV1) in the vaccine in collaboration with the 12 members of the Vaccines and Related Biological Products Advisory Committee (VRBPAC). On May 6, 2010, the FDA announced its decision to revoke the suspension, stating that porcine circovirus types 1 and 2 pose no safety risks in humans and concluded that health risks involved did not offset the benefits of the vaccination. In May 2010 the suspension of the Rotarix vaccine was lifted. Research
Doctors Without Borders (MSF) developed a heat-stable version named BRV-PV. Phase 3 of the clinical trials were completed in Niger on December 31, 2020.The vaccine has been associated with lower rates of type 1 diabetes. References
