Rotavirus Serotype G9 Is Associated with More‐Severe Disease in Latin America

Abstract

The association between rotavirus serotypes and severity is not well established. Analysis of a clinical trial conducted in Latin America points at more-severe disease associated with serotype G9. Thus, demonstration of efficacy against G9 will be an important asset of any rotavirus vaccine to be introduced into a Latin American country or any country where G9 has been shown to be prevalent.
