Background

The emergence of the new SARS-CoV-2 virus and the accompanying prevention and control measures (eg non-pharmaceutical interventions (NPIs)) have had a major impact on the global circulation of other respiratory viruses, including influenza. The low levels of influenza activity observed since the start of the COVID-19 pandemic may have led to an increased proportion of susceptible subjects in the population and there is the strong potential for a resurgence of influenza cases in the coming season, especially with a scenario where NPIs are relaxed. Scenarios which consider the local context of NPIs and vaccination coverage rates (VCRs) of Influenza and COVID-19 are therefore required to support vaccine policy recommendations and ultimately best protect vulnerable populations.
