The aim of this study is to monitor any impact in the change from the lyophilised formulation to the liquid formulation of the Rotarix™ vaccine on hospitalisations for rotavirus gastroenteritis. This is planned to be assessed by comparing trends of hospitalisations due to laboratory confirmed rotavirus gastroenteritis in children <=5 years of age, before and after introduction of the liquid formulation of the vaccine in Belgium.

Primary Outcome Measures:
  • Occurrence of rotavirus in hospitalised children aged ≤5 years during pre-introduction, introduction and post-introduction period of liquid formulation Rotarix™ [ Time Frame: up to 2 years post-introduction of liquid formulation of Rotarix™. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Occurrence of rotavirus detected by laboratory tests in children of various age, gender and location (centre and region). [ Time Frame: up to 2 years post-introduction of liquid formulation of Rotarix™. ] [ Designated as safety issue: No ]
  • Occurrence of rotavirus detected by laboratory tests at a specific time (month and year). [ Time Frame: up to 2 years post-introduction of liquid formulation of Rotarix™. ] [ Designated as safety issue: No ]
  • Occurrence of rotavirus detected by various types of rotavirus laboratory tests. [ Time Frame: up to 2 years post-introduction of liquid formulation of Rotarix™. ] [ Designated as safety issue: No ]
  • Occurrence of rotavirus vaccination with a specific brand of vaccine (Rotarix and RotaTeq) among children ≤5 years of age in the Belgian population. [ Time Frame: up to 2 years post-introduction of liquid formulation of Rotarix™. ] [ Designated as safety issue: No ]

Groups/Cohorts Assigned Interventions
Cohort A
Children aged <=5 years in Belgium, with opportunity to receive Rotarix, requiring hospitalisation during which rotavirus detection test was performed and with available results.
Other: Data collection
Data collected when only the lyophilised formulation of Rotarix was in use (which is considered as baseline) will be specifically compared to data collected post the introduction of the liquid formulation. The results will also be compared to available vaccine coverage data for those rotavirus vaccines being used in Belgium.


Ages Eligible for Study:   up to 5 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Children hospitalised due to laboratory confirmed rotavirus gastroenteritis in approximately 8 hospitals across Belgium.


Inclusion Criteria:

All subjects must satisfy ALL the following criteria at study entry:

  • Child aged ≤5 years with opportunity to receive lyophilised or liquid formulation of Rotarix™;
  • Hospitalised at one of the participating centres in Belgium;
  • A stool sample has been provided for a rotavirus detection test during the study period;
  • Laboratory test result of rotavirus is available.

Exclusion Criteria:

• None.
