Epidemiological, Observational and Post Marketing Study of Rotarix™ in Children With Severe Gastroenteritis in Belgium

January 16, 2017 updated by: GlaxoSmithKline

Epidemiological, Observational, Post Marketing Study of the Genetic Stability of GSK Biologicals' Rotavirus Vaccine (Rotarix™) in Children <5 Years of Age Diagnosed With Severe Gastroenteritis, in Belgium

The main aim of this study is to investigate cases of rotavirus gastroenteritis in Belgian children with opportunity to receive Rotarix™ to monitor the potential occurrence of genetic drifts (point mutations) in the vaccine strain and the occurrence of genetic shifts (re-assortments) between vaccine and naturally circulating wild-type strains in Belgium population after the introduction of Rotarix™. The study will also detect if there is any alteration in rotavirus pathogenicity conferred by re-assortment and if the mutated vaccine strain is still efficacious in preventing rotavirus gastroenteritis.

Detailed Description

This study is conducted in two phases: Phase I and Phase II. Phase I will be retrospective and consist of re-using the data collected in RotaBel (EPI-ROTA-111426) study. Phase II will be prospective and consist of maintaining the active surveillance system to identify rotavirus cases in several hospitals in Belgium.
