Influenza A virus (IAV) and SARS-CoV-2 coinfection is a possible scenario during influenza season. Here, the authors show in a mouse model that IAV infection increases the risk of severe disease upon SARS-CoV-2 infection two days later. IAV vaccination, especially antibody-dependent, protects from severe disease during coinfection.
