Abstract
- Cocirculation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses could pose unpredictable risks to health systems globally, with recent studies suggesting more severe disease outcomes in coinfected patients. The initial lack of a readily available coronavirus disease 2019 (COVID-19) vaccine has reinforced the importance of influenza vaccine programs during the COVID-19 pandemic. Live attenuated influenza vaccine (LAIV) is an important tool in protecting against influenza, particularly in children. However, it is unknown whether LAIV administration influences the outcomes of acute SARS-CoV-2 infection or disease. To investigate this, quadrivalent LAIV was administered to ferrets 3 days before or after SARS-CoV-2 infection. LAIV administration did not exacerbate the SARS-CoV-2 disease course or lung pathology with either regimen. In addition, LAIV administered before SARS-CoV-2 infection significantly reduced SARS-CoV-2 replication and shedding in the upper respiratory tract. This study demonstrated that LAIV administration in close proximity to SARS-CoV-2 infection does not exacerbate mild disease and can reduce SARS-CoV-2 shedding.
