A meta-analysis of studies measuring the impact of rotavirus vaccine (RVV) on severe gastroenteritis morbidity and mortality, found a 22% herd immunity effect for severe rotavirus gastroenteritis in children less than one year of age in US and El Salvador.  In Latin America, severe gastroenteritis due to any cause was reduced by 25%.

Key Idea

A meta-analysis of data from studies measuring the impact of rotavirus vaccine (RVV) on severe gastroenteritis morbidity and mortality reported a median herd immunity effect for severe rotavirus gastroenteritis in children less than one year of age of 22% (US and El Salvador).  In studies in Latin America reporting an all-cause gastroenteritis benefit the median herd effect for severe gastroenteritis was 24.9%.
