The Centers of Excellence for Influenza Research and Response (CEIRR) Network is a multidisciplinary and collaborative research network funded by the National Institute of Allergy and Infectious Diseases (NIAID) to study the natural history, transmission, and pathogenesis of influenza and provide an international research infrastructure to address influenza outbreaks.

CEIRR Centers conduct studies to study key influenza research areas and provide pandemic response. CEIRR projects aim to better understand the immune response to influenza vaccination and infection, and identify immunological factors that contribute to disease severity. Surveillance projects investigate how influenza viruses infect, evolve, and transmit in both human and animal infections. Although CEIRR is primarily focused on influenza, the Network also studies severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes COVID-19, as well as other emerging viruses of pandemic potential.
