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.
Study Overview
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.
