To address the challenges posed by influenza, its associated complications, and economic burden, the World Health Organization recommends a vaccination rate exceeding 75 % for populations at elevated risk of severe diseases. Presently, vaccination rates in Germany severely lag behind. To augment these rates, pilot projects have been initiated, allowing community pharmacists to administer vaccines.

Syndromic multiplex panel testing enables simultaneous detection of multiple respiratory pathogens, but limited data is available on the comparative diagnostic performance of different testing systems. In this multicenter prospective study, we aimed to compare the QIAstat-Dx Respiratory Panel 2.0 (QIAstat-Dx-RP2.

Neutralizing antibodies (nAbs) are important for the treatment of emerging viral diseases and for effective vaccine development. In this study, we generated and evaluated three nAbs (1H9, 2D7, and C4H4) against H7N9 influenza viruses and found that they differ in their ability to inhibit viral attachment, membrane fusion, and egress. We resolved the cryo-electron microscopy (cryo-EM) structures of H7N9 hemagglutinin (HA) alone and in complex with the nAb antigen-binding fragments (Fabs) and identified the HA head-located epitope for each nAb, thereby revealing the molecular basis and key residues that determine the differences in these nAbs in neutralizing H7N9 viruses.

From 2020, influenza viruses circulation was largely affected by the global coronavirus disease (COVID-19) pandemic, notably leading to the extinction of the B/Yamagata lineage and raising questions about the relevance of the quadrivalent influenza vaccine, which includes this lineage. Evaluating vaccine effectiveness (VE) against influenza infections is important to inform future vaccine programs. A test-negative case-control study was conducted in five tertiary hospitals in Hangzhou, the capital city of Zhejiang province, China, enrolling medically-attended patients aged >6 months who presented with influenza-like illness (ILI) from October 1, 2023, to March 31, 2024.

Background: Influenza A/Hong Kong/125/2017 (H7N9) virus poses a pandemic risk owing to its evolving nature. This study evaluated the immunogenicity and safety of an AS03-adjuvanted H7N9 vaccine in adults (18-64 years [younger] and ≥65 years [older]).
Methods: Participants (younger, n = 418; older, n = 420) were randomized to receive one of six adjuvanted vaccines (hemagglutinin [1.
