dc.description.abstractIntroduction: From September to November 2025, many European countries launched COVID-19 vaccination campaigns, when SARS-CoV-2 incidence was decreasing after a period of high circulation.1 These campaigns targeted specific groups, including older adults (ie, individuals aged at or above a minimum threshold that varied from age 60 to 70 years across countries). We estimated the effectiveness of COVID-19 vaccines administered during these seasonal vaccination campaigns in Europe against medically attended, symptomatic SARS-CoV-2 infection among older adults, from September 29, 2025, to January 10, 2026.eng
dc.description.abstractPlain language summary: This case-control study examines COVID-19 vaccine effectiveness against symptomatic SARS-CoV-2 infection among older adults in Europe.eng
dc.description.sponsorshipThis study was funded by the framework contract ECDC/2021/019 from the European Centre for Disease Prevention and Control (ECDC).
