Objective: In Europe, the age indication for the MF59-adjuvanted quadrivalent influenza vaccine (aQIV) has recently been extended from ≥65 to ≥50 years. Considering that the earliest approval of its trivalent formulation (aTIV) in Italy was for people aged ≥12 years, we aimed to systematically appraise data on the immunogenicity, efficacy, and safety of aTIV/aQIV in non-elderly adults.
Methods: A systematic literature review was conducted according to the available guidelines and studies were searched in MEDLINE, Biological Abstracts, Web of Science, Cochrane Library and clinical trial registries.

The immune escape capacities of XBB variants necessitate the authorization of vaccines with these antigens. In this study, we produce three recombinant trimeric proteins from the RBD sequences of Delta, BA.5, and XBB.

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.

The spread of multidrug-resistant strains of poses a great challenge in gonorrhea treatment. At present, vaccination is the best strategy for gonorrhea control. However, given the extensive antigenic variability of , the effectiveness of monovalent vaccines is limited.

The continued emergence of SARS-CoV-2 variants and the threat of future Sarbecovirus zoonoses have spurred the design of vaccines that can induce broad immunity against multiple coronaviruses. Here, we use computational methods to infer ancestral phylogenetic reconstructions of receptor binding domain (RBD) sequences across multiple Sarbecovirus clades and incorporate them into a multivalent adenoviral-vectored vaccine. Mice immunized with this pan-Sarbecovirus vaccine are protected in the upper and lower respiratory tracts against infection by historical and contemporary SARS-CoV-2 variants, SARS-CoV, and pre-emergent SHC014 and Pangolin/GD coronavirus strains.
