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...
Vaccine effectiveness against influenza hospitalisation in adults during the 20...
Rose, Angela M. C.; Pozo, Francisco; Martínez‐Baz, Iván; Mazagatos, Clara; Bossuyt, Nathalie; Cauchi, John Paul; Petrović, Goranka; Loghin, Isabela I.We conducted a multicentre hospital-based test-negative case–control study to measure vaccine effectiveness (VE) against PCR-confirmed influenza in adult patients with severe acute respiratory infection (SARI) during the 2022/2023 influenza season in Europe. Among 5547 SARI patients ≥18 years, 2963 (53%) were vaccinated against influenza. Overall VE against influenza A(H1N1)pdm09 was 11% (95% CI: −23–36); 20% (...
Health and economic impact of seasonal influenza mass vaccination strategies in...
Sandmann, Frank; van Leeuwen, Edwin; Bernard-Stoecklin, Sibylle; Casado, Itziar; Castilla, Jesús; Domegan, Lisa; Gherasim, Alin; Hooiveld, MariëtteIntroduction: Despite seasonal influenza vaccination programmes in most countries targeting individuals aged ≥ 65 (or ≥ 55) years and high risk-groups, significant disease burden remains. We explored the impact and cost-effectiveness of 27 vaccination programmes targeting the elderly and/or children in eight European settings (n = 205.8 million). Methods: We used an age-structured dynamic-transmission model to ...
Excess all-cause mortality during the COVID-19 pandemic in Europe – preliminary...
Vestergaard, Lasse S.; Nielsen, Jens; Richter, Lukas; Schmid, Daniela; Bustos, Natalia; Braeye, Toon; Denissov, Gleb; Veideman, Tatjana; Luomala, OskariA remarkable excess mortality has coincided with the COVID-19 pandemic in Europe. We present preliminary pooled estimates of all-cause mortality for 24 European countries/federal states participating in the European monitoring of excess mortality for public health action (EuroMOMO) network, for the period March–April 2020. Excess mortality particularly affected ≥ 65 year olds (91% of all excess deaths), but al...
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 ...
Exploring the effect of previous inactivated influenza vaccination on seasonal ...
Valenciano, Marta; Kissling, Esther; Larrauri, Amparo; Nunes, Baltazar; Pitigoi, Daniela; O'Donnell, Joan; Reuss, Annicka; Horváth, Judit KrisztinaBACKGROUND: Results of previous influenza vaccination effects on current season influenza vaccine effectiveness (VE) are inconsistent. OBJECTIVES: To explore previous influenza vaccination effects on current season VE among population targeted for vaccination. METHODS: We used 2011/2012 to 2016/2017 I-MOVE primary care multicentre test-negative data. For each season, we compared current season adjusted VE (aVE)...
Estimates of pandemic influenza vaccine effectiveness in Europe, 2009-2010: res...
Valenciano, Marta; Kissling, Esther; Cohen, Jean-Marie; Oroszi, Beatrix; Barret, Anne-Sophie; Rizzo, Caterina; Nunes, Baltazar; Pitigoi, DanielaA multicentre case-control study based on sentinel practitioner surveillance networks from seven European countries was undertaken to estimate the effectiveness of 2009-2010 pandemic and seasonal influenza vaccines against medically attended influenza-like illness (ILI) laboratory-confirmed as pandemic influenza A (H1N1) (pH1N1).
