Live-attenuated influenza vaccine (LAIV) delivered by large droplet intranasal spray is efficacious against infection. However, many of the large droplets are trapped in the external nares and do not reach the target nasal airway tissues. Smaller droplets might provide better distribution yielding similar protection with lower doses. We evaluated 20 and 30 μm aerosol delivery of influenza virus in mice. A 15s aerosol exposure optimally protected against homologous and heterologous influenza infection and induced a robust immune response. These results demonstrate the feasibility of nasal vaccination using aerosolized particles, providing a strategy to improve vaccine efficacy and delivery.

Rhabdomyolysis or Crush syndrome-related AKI (RM/CS-AKI) has high mortality, and there is no effective early on-site treatment method. The critical pathogenic factor of RM/CS-AKI is the excessive free myoglobin (Mb) in blood circulation. Here, based on the concept of creating a "mobile barrier", we develop an anti-Mb rabbit monoclonal antibody (RabMAb) with high specificity, affinity, stability, and broad species reactivity.

Rose Bengal antigen and smooth lipopolysaccharide (s-LPS) were produced from a field strain of ("homologous" antigens) and from the reference strain S99 ("heterologous" antigens); they are currently used for the diagnosis of brucellosis in cattle, water buffaloes, sheep, goats, and pigs, as recommended in the Manual of Diagnostic Tests and Vaccines for Terrestrial Animals of the World Organization for Animal Health (WOAH). "Homologous" and "heterologous" antigens were used in a rapid serum agglutination test (Rose Bengal test, RBT) and a competitive ELISA assay (c-ELISA) to test a panel of sera, blood, and other body fluids (cerebrospinal fluid, pericardial fluid, tracheal fluid, and aqueous humor) collected from 71 individuals belonging to five cetacean species (; ; ; ; and ), which were found stranded on the Italian coastline. Six animals were positive for spp.

Background: Vaccination has played a crucial role in mitigating the spread of COVID-19 and reducing its severe outcomes. While over 90% of Bangladesh's population has received at least one COVID-19 vaccine dose, the comparative effectiveness of homologous versus heterologous booster strategies, along with the complex interplay of factors within the population, remains understudied. This study aimed to compare antibody responses between these booster approaches.
