How existing immunity affects the spread of influenza viruses in the air

Official title: Role of preexisting immunity on airborne transmission of influenza viruses

Funded at Emory University · NIH-11007241 · Data updated 2026-11-12

This study looks at how having had the flu before affects how easily the flu spreads in the air, using ferrets to help understand this, and it also checks how changes in immunity and the virus itself influence this spread, while testing different vaccines to see how well they protect against new flu strains.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals with a history of influenza infections or vaccinations who may be at risk for airborne transmission of the virus.

Less likely to help

Patients who have never been infected with influenza or vaccinated against it may not benefit from this research.

What this research studies

This research investigates how pre-existing immunity from previous influenza infections influences the ability of influenza viruses to spread through the air. Using ferrets as a model, the study aims to identify the immunological and viral factors that affect susceptibility to airborne transmission. It will also explore how seasonal changes in population immunity and the evolution of the virus impact transmission dynamics. Additionally, the research will assess the effectiveness of different vaccine platforms in providing protection against new strains of the virus.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for preventing the spread of influenza viruses, potentially reducing the incidence of seasonal epidemics and pandemics.

How similar studies have gone: Previous studies using similar approaches have shown promising results in understanding the role of immunity in influenza transmission, indicating that this research builds on established findings.
