Although influenza activity was historically low during the 2020/21 influenza season, we could experience an influenza activity surge this coming season with relaxed COVID-19 mitigation strategies, increased travel and the reopening of schools and businesses. Influenza vaccination remains the best available preventive measure against influenza particularly in groups recommended vaccination. Even in cases when influenza vaccination does not completely prevent infection, studies have shown [20] it can reduce the duration and severity of illness and help prevent serious complications, including hospitalisation and death. Vaccination is going to be especially important in the 2021/22 season if influenza and SARS-CoV-2 viruses would co-circulate. In this possible scenario, influenza vaccination and the strengthening of an integrated surveillance of influenza viruses and SARS-CoV-2 are critical elements in preparing for a possible resurgence of influenza in the 2021/22 season.
