Global Experience With Rotavirus Vaccines.

Rotavirus is a major cause of severe pediatric diarrhea worldwide. In 2006, 2 live, oral rotavirus vaccines, Rotarix and RotaTeq, were licensed for use in infants and were rapidly adopted in many high- and middle-income settings where efficacy had been demonstrated in clinical trials. Following completion of successful trials in low-income settings, the World Health Organization (WHO) recommended rotavirus vaccination for all infants globally in 2009. In 2018, 2 new rotavirus vaccines, Rotasiil and Rotavac, were prequalified by WHO, expanding global availability. As of March 2021, rotavirus vaccines have been introduced nationally in 106 countries. Since, Rotavirus vaccines have demonstrated effectiveness against severe disease and mortality, even among age groups in eligible for vaccination. Cross-genotypic protection has been demonstrated, and the favorable benefit-risk profile of these vaccines continues to be confirmed. Ongoing research seeks to better understand reasons for the geographic disparities in effectiveness observed, in order to optimize vaccine strategies worldwide. © The Author(s) 2021.
