We estimated XBB.1.5 vaccine effectiveness (VE) against symptomatic
SARS-CoV-2 infection among adults aged ≥65 years during the 2023/24 JN.1
lineage-predominant period in a European multi-country test-negative
case-control study at primary care level. We estimated VE adjusted by
study site, age, sex, chronic conditions and onset date. We included 220
cases and 1733 controls. The VE was 48% (95% CI: 12–71), 23% (95%
CI: -11–48) and 5% (95% CI: -92–56) among those with symptom onset
1–5 , 6–11, and ≥12 weeks after vaccination, respectively. XBB.1.5
vaccine provided short and moderate protection against JN.1 symptomatic
infection.Submitted to Influenza and other respiratory viruses Submission Checks Completed
