Global and Swedish review of rotavirus vaccines showed considerable reductions in morbidity and mortality

Abstract

Rotavirus infections cause severe gastroenteritis in small children, with both high morbidity and mortality. The rotavirus vaccine has been recommended by the World Health Organization since 2009 and was being used by 108 countries by 2019. It joined Sweden's national immunisation programme that year, after 5 years of selective regional use. This review summarises the baseline facts and evidence, the most common vaccines and the global direct and indirect effects, with a special focus on Sweden. Conclusion: The vaccine has had a considerable impact on global and Swedish morbidity and mortality, but some indirect effects and socioeconomic differentials need research.
