European Influenza Surveillance Scheme
The European Influenza Surveillance Scheme was a coordinated regional network for monitoring seasonal and pandemic influenza across the European region, designed to link national systems, laboratories, and clinical sites to inform World Health Organization policy and guide national European Commission preparedness. It integrated data streams from sentinel primary care, hospital, and virology laboratories to support situational awareness for European Centre for Disease Prevention and Control, World Health Organization Regional Office for Europe, United Nations health policy, and national public health agencies including Public Health England, Robert Koch Institute, and Santé publique France. The Scheme contributed to vaccine composition advice delivered by the Global Influenza Surveillance and Response System and influenced decisions by National Institutes of Health partners and international bodies such as the Centers for Disease Control and Prevention.
History
The Scheme emerged in the mid-1990s amid increasing attention to influenza after events involving 1997 H5N1 outbreak, 1997–1998 influenza season, and earlier pandemics like the 1918 influenza pandemic, prompting coordination among institutions such as the World Health Organization Regional Office for Europe, European Commission Directorate-General for Health and Food Safety, European Centre for Disease Prevention and Control predecessor initiatives, and national bodies including Instituto Superiore di Sanità, Statens Serum Institut, and Karolinska Institutet. Its development paralleled surveillance expansions after outbreaks such as 2003 SARS outbreak, 2009 swine flu pandemic, and interactions with networks like the Global Health Security Agenda and the Network for European Surveillance of Antimicrobial Resistance. Over time the Scheme adapted to new laboratory methods from groups at Pasteur Institute, Shipboard laboratories, and university centres including University of Oxford, Imperial College London, Helsinki University Hospital, and Charité – Universitätsmedizin Berlin. Reforms integrated data-sharing practices promoted by the European Medicines Agency and collaborative research with entities like Wellcome Trust, European Research Council, and multinational consortia including PREPARE.
Objectives and Scope
Primary objectives included early detection of seasonal and novel influenza strains to inform vaccine strain selection advised to the World Health Organization and to support national responses by agencies such as Public Health Scotland, FISABIO, and Instituto de Salud Carlos III. The Scheme sought to harmonize surveillance definitions used by National Public Health Institute counterparts, standardize virological methods employed by networks such as the European Reference Laboratory Network, and provide data for modelling teams at London School of Hygiene & Tropical Medicine, Institute Pasteur, and ETH Zurich. Scope covered sentinel primary care, hospitalizations, severe acute respiratory infections tracked by hospitals like Rigshospitalet, Hôpital Necker-Enfants Malades, and long-term surveillance across territories including Iceland, Norway, Spain, Poland, Italy, Germany, France, United Kingdom, and Portugal.
Surveillance Methods
Surveillance methods combined clinical surveillance from sentinel providers associated with centres such as Karolinska University Hospital and laboratory confirmation by reference centres like National Institute for Public Health and the Environment (RIVM). Syndromic surveillance drew on emergency department reporting mechanisms used by Helsinki University Central Hospital and general practice networks modelled at McMaster University collaborations, while virological surveillance used techniques refined at Institut Pasteur, Erasmus Medical Center, and University College London. Epidemiological approaches incorporated age-stratified incidence estimation used in analyses at University of Cambridge, vaccine effectiveness study designs informed by experts from Centers for Disease Control and Prevention, and statistical modelling frameworks from Imperial College London and European Centre for Disease Prevention and Control teams.
Data Collection and Reporting
Data collection combined weekly reports from national focal points such as Robert Koch Institute and Instituto de Salud Carlos III with laboratory submissions to reference centres like Statens Serum Institut and National Institute for Communicable Diseases. Reporting fed into regional bulletins produced in collaboration with World Health Organization Regional Office for Europe, and datasets were used by modelling groups at European Molecular Biology Laboratory, Max Planck Institute for Infection Biology, and London School of Hygiene & Tropical Medicine. The Scheme navigated data standards and interoperability influenced by European Commission directives and privacy frameworks shaped by institutions like the European Data Protection Supervisor and informed by researchers at University of Copenhagen and Trinity College Dublin.
Laboratory Network and Virology
A distributed laboratory network linked national reference laboratories such as Statens Serum Institut, Robert Koch Institute, National Institute for Public Health and the Environment, Instituto Superiore di Sanità, and Pasteur Institute branches, enabling antigenic and genetic characterisation, sequencing contributions to databases used by Global Initiative on Sharing Avian Influenza Data participants, and antiviral resistance monitoring informed by studies at Karolinska Institutet and University of Oxford. Techniques included RT-PCR protocols standardised with input from Centers for Disease Control and Prevention laboratories, virus isolation methods used at Erasmus Medical Center, and next-generation sequencing workflows developed through collaborations with Wellcome Sanger Institute and European Bioinformatics Institute.
Public Health Impact and Response
Outputs informed vaccine composition meetings that influenced seasonal vaccine recommendations by World Health Organization advisory groups, supported national immunisation campaigns at organisations like NHS England, Istituto Superiore di Sanità, and Santé publique France, and guided antiviral stockpiling strategies considered by ministries including Ministry of Health (United Kingdom), Ministry of Health (Italy), and Bundesministerium für Gesundheit. Surveillance findings underpinned pandemic preparedness plans that referenced historic events such as the 2009 swine flu pandemic and collaborated with emergency response actors like European Civil Protection and Humanitarian Aid Operations and UNICEF for risk communication and vaccine distribution logistics.
Governance and Collaboration
Governance involved coordination among World Health Organization Regional Office for Europe, European Centre for Disease Prevention and Control, national public health institutes including Robert Koch Institute, Public Health England, Instituto de Salud Carlos III, and academic partners such as Imperial College London and Karolinska Institutet. Collaborative frameworks incorporated research funding by European Commission Framework Programmes, partnerships with philanthropic bodies like Wellcome Trust, and legal and policy guidance from entities such as the European Commission and European Parliament. The Scheme interfaced with global initiatives including the Global Influenza Surveillance and Response System and contributed to capacity-building efforts in countries across the European Region.
