Influenza vaccine effectiveness in Europe: Results from the 2022–2023 VEBIS (Va...
Maurel, Marine; Pozo, Francisco; Pérez‐Gimeno, Gloria; Buda, Silke; Sève, Noémie; Oroszi, Beatrix; Hooiveld, Mariette; Gómez, Verónica; Domegan, LisaBackground: Influenza A(H3N2) viruses dominated early in the 2022-2023 influenza season in Europe, followed by higher circulation of influenza A(H1N1)pdm09 and B viruses. The VEBIS primary care network estimated the influenza vaccine effectiveness (VE) using a multicentre test-negative study. Materials and methods: Primary care practitioners collected information and specimens from patients consulting with acut...
Rapidly adapting primary care sentinel surveillance across seven countries in E...
Bagaria, Jayshree; Jansen, Tessa; Marques, Diogo F.P.; Hooiveld, Mariette; McMenamin, Jim; de Lusignan, Simon; Vilcu, Ana-Maria; Meijer, AdamAs the COVID-19 pandemic began in early 2020, primary care influenza sentinel surveillance networks within the Influenza - Monitoring Vaccine Effectiveness in Europe (I-MOVE) consortium rapidly adapted to COVID-19 surveillance. This study maps system adaptations and lessons learned about aligning influenza and COVID-19 surveillance following ECDC / WHO/Europe recommendations and preparing for other diseases pos...
Effectiveness of influenza vaccine against influenza A in Europe in seasons of ...
Kissling, Esther; Pozo, Francisco; Buda, Silke; Vilcu, Ana-Maria; Rizzo, Caterina; Gherasim, Alin; Krisztina Horváth, Judit; Brytting, MiaIntroduction: Influenza A(H3N2) viruses predominated in Europe in 2016–17. In 2017–18 A(H3N2) and A(H1N1)pdm09 viruses co-circulated. The A(H3N2) vaccine component was the same in both seasons; while the A(H1N1)pdm09 component changed in 2017–18. In both seasons, vaccine seed A(H3N2) viruses developed adaptations/alterations during propagation in eggs, impacting antigenicity. Methods: We used the test-negative ...
Measuring the impact of influenza vaccination programmes among the elderly popu...
Mazagatos, Clara; Machado, Ausenda; Dijkstra, Frederika; Kissling, Esther; Larrauri, Amparo; Kislaya, Irina; van Gageldonk-Lafeber, RianneMeasuring the number of influenza-associated events prevented by influenza vaccination among the elderly in the European Union would allow a better understanding of the overall impact of influenza vaccination programmes, particularly in seasons with low influenza vaccine effectiveness (IVE). This study measured the number of medically attended influenza-confirmed cases in primary care (MAICC) among those ≥65 ye...
Impact of influenza vaccination programmes among the elderly population on prim...
Machado, Ausenda; Mazagatos, Clara; Dijkstra, Frederika; Kislaya, Irina; Gherasim, Alin; McDonald, Scott A.; Kissling, Esther; Valenciano, MartaTo increase the acceptability of influenza vaccine, it is important to quantify the overall benefits of the vaccination programme.AimTo assess the impact of influenza vaccination in Portugal, Spain and the Netherlands, we estimated the number of medically attended influenza-confirmed cases (MAICC) in primary care averted in the seasons 2015/16 to 2017/18 among those ≥ 65 years.We used an ecological approach to ...
2015/16 I-MOVE/I-MOVE+ multicentre case control study in Europe: moderate vacci...
Kissling, Esther; Valenciano, Marta; Pozo, Francisco; Vilcu, Ana-Maria; Reuss, Annicka; Rizzo, Caterina; Larrauri, Amparo; Horváth, Judit KrisztinaBackground:During the 2015/16 influenza season in Europe, the co-circulating influenza viruses were A(H1N1)pdm09 and B/Victoria, which was antigenically distinct from the B/Yamagata component in the trivalent influenza vaccine. Methods:We used the test negative design in a multicentre case–control study in twelve European countries to measure 2015/16 influenza vaccine effectiveness (VE) against medically-attend...
