What

Scientists and clinicians from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and the California Institute of Technology discuss key considerations for developing a universal influenza vaccine in a meeting report appearing in the October 17 issue of Immunity. The report summarizes discussions from a workshop NIAID held June 28-29, 2017, in Rockville, Maryland, entitled, “Pathway to a Universal Influenza Vaccine.” The workshop brought together U.S. and international experts from academia, industry and government to identify knowledge gaps in influenza research and to set goals to fill these knowledge gaps. NIAID will use the report to develop a strategic plan and research agenda aimed at the development of a universal influenza vaccine.

Licensed influenza vaccines provide suboptimal protection against seasonal influenza, must be updated regularly to match circulating influenza strains, and offer little or no protection against newly emerged pandemic influenza strains. Thus, a key public health goal is to develop a universal influenza vaccine that would protect against most or all seasonal strains of influenza virus and potential pandemic strains. Scientists have been developing universal influenza vaccine strategies, including vaccines that target conserved areas of the influenza virus that remain relatively unchanged season-to-season. However, critical scientific questions remain unanswered and must be addressed to accelerate this research.

Meeting attendees noted the need for improved influenza surveillance (especially in certain regions and subpopulations), as well as a better characterization of how influenza viruses are transmitted. They also encouraged more research on immune responses to influenza vaccination and infection, including the impact of pre-existing immunity on responses to future vaccinations or influenza exposures. One way to address these questions, the report notes, would be to conduct long-term natural history studies that include people of various ages from different regions of the world. Such studies could also help define other factors that affect host immunity and delineate mediators of viral pathogenesis. Standardized human challenge models—studies in which healthy adult volunteers are purposely infected with influenza under careful medical supervision in an inpatient setting—could serve as another tool to help understand immunity to influenza and rapidly assess new vaccine candidates.

Meeting attendees discussed limitations in current influenza diagnostics, and the report calls for improved techniques to define and measure correlates of protection against influenza infection. They also debated the pros and cons of using various animal models to test vaccine candidates, study influenza transmission and better understand viral pathogenesis and the immune response to influenza. The report concludes by emphasizing the need for improved coordination among various scientific disciplines to prioritize and ultimately realize shared research goals.

Dr. Marta Lopez De Diego, Research Assistant Professor in the Topham Lab, receives University Research Award to further analyze NS1 protein variability in the current seasonal influenza A H1N1 and H3N2 viruses and characterize the effect of the identified mutations on evading host innate immune responses and in modulating viral pathogenesis The project is entitled “Role of NS1 mutations in interferon responses, inflammation and pathogenesis induced by seasonal human influenza A viruses,” and is a collaboration between Dr. Marta Lopez De Diego and Dr. Aitor Nogales Gonzalez in the at the University of Rochester.
