- COVID-19 Vaccine Effectiveness Against Hospitalization in Older Adults, VEBIS Hospital Network, Europe, September 2024-May 2025Publication . Rojas-Castro, Madelyn; Verdasca, Nuno; Monge, Susana; De Mot, Laurane; Trobajo-Sanmartín, Camino; Duffy, Róisín; Túri, Gergő; Kuliese, Monika; Duerrwald, Ralf; Borg, Maria-Louise; Popovici, Odette; Gomez, Verónica; Makarić, Zvjezdana Lovrić; Launay, Odile; Marques, Diogo F.P.; Pozo, Francisco; Witdouck, Arne; Martínez-Baz, Iván; Fitzgerald, Margaret; Oroszi, Beatrix; Jančorienė, Ligita; Buda, Silke; Dziugyte, Ausra; Lazăr, Mihaela; Machado, Ausenda; Tabain, Irena; Nguyen, Liem Binh Luong; Wagner, Eva Rivas; Dufrasne, François; Castilla, Jesús; Domegan, Lisa; Velkey, Viktória; Majauskaite, Fausta; Hackmann, Carolin; Nicolay, Nathalie; Bacci, Sabrina; Rose, Angela M.C.; European Hospital Vaccine Effectiveness GroupWe estimated COVID-19 vaccine effectiveness (VE) against PCR-confirmed SARS-CoV-2 hospitalization in patients ≥ 60 years with severe acute respiratory infection, using a multicenter, test-negative, case-control study across seven sites in six European countries between September 2024 and May 2025. We included 352 cases (115 vaccinated; 33%) and 9980 controls (5024 vaccinated; 50%). VE was 42% (95% CI: 15; 61) 14-59 days post-vaccination, 32% (95% CI: -1; 54) at 60-119 days, and 36% (95% CI: 2; 60) at 120-179 days, and no effect thereafter. Among adults aged 60-79 and ≥ 80 years, we observed moderate VE against COVID-19 hospitalization for up to 2 and 4 months, respectively.
- Interim 2024/25 influenza vaccine effectiveness: eight European studies, September 2024 to January 2025Publication . Rose, Angela; Lucaccioni, Héloïse; Marsh, Kimberly; Kirsebom, Freja; Whitaker, Heather; Emborg, Hanne-Dorthe; Botnen, Amanda Bolt; O’Doherty, Mark G.; Pozo, Francisco; Shahul Hameed, Safraj; Andrews, Nick; Hamilton, Mark; Lauenborg Møller, Karina; Trebbien, Ramona; Marques, Diogo F.P.; European IVE groupThe 2024/25 influenza season in Europe is currently characterised by the co-circulation of influenza A(H1N1)pdm09, A(H3N2) and B/Victoria viruses, with influenza A(H1N1)pdm09 predominating. Interim vaccine effectiveness estimates from eight European studies conducted in 17 countries indicate an overall influenza A vaccine effectiveness of 32–53% in primary care settings and 33–56% in hospital settings, with some indications of lower effectiveness by subtype and higher effectiveness against influenza B (≥58% across settings). Where feasible, influenza vaccination should be encouraged and other preventive measures strengthened.
- Rapidly adapting primary care sentinel surveillance across seven countries in Europe for COVID-19 in the first half of 2020: strengths, challenges, and lessons learnedPublication . Bagaria, Jayshree; Jansen, Tessa; Marques, Diogo F.P.; Hooiveld, Mariette; McMenamin, Jim; de Lusignan, Simon; Vilcu, Ana-Maria; Meijer, Adam; Rodrigues, Ana Paula; Brytting, Mia; Mazagatos, Clara; Cogdale, Jade; van der Werf, Sylvie; Dijkstra, Frederika; Guiomar, Raquel; Enkirch, Theresa; Valenciano, Marta; I-MOVE-COVID-19 study teamAs 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 possibly emerging in the future. Using a qualitative approach, we describe the adaptations of seven sentinel sites in five European Union countries and the United Kingdom during the first pandemic phase (March–September 2020). Adaptations to sentinel systems were substantial (2/7 sites), moderate (2/7) or minor (3/7 sites). Most adaptations encompassed patient referral and sample collection pathways, laboratory testing and data collection. Strengths included established networks of primary care providers, highly qualified testing laboratories and stakeholder commitments. One challenge was the decreasing number of samples due to altered patient pathways. Lessons learned included flexibility establishing new routines and new laboratory testing. To enable simultaneous sentinel surveillance of influenza and COVID-19, experiences of the sentinel sites and testing infrastructure should be considered. The contradicting aims of rapid case finding and contact tracing, which are needed for control during a pandemic and regular surveillance, should be carefully balanced.
