Abstract: Between October 2024 and February 2025, influenza A(H1N1)pdm09 initially predominated in Germany, with subsequent co-circulation of influenza B/Victoria. We provide interim estimates of 2024/2025 influenza vaccine effectiveness (VE) in Germany across primary care and secondary care. VE against any influenza in primary care was 31% (95% CI: 1-52). Interim VE was high against influenza B; however, interim estimations indicated a much lower VE against influenza A especially in the adult age group below 60 years. In secondary care, VE against any influenza was 69% (95% CI: 21-88). Our findings support promoting influenza vaccination alongside infection-preventing behavior and prompt antiviral therapy.
