[1] on the influenza vaccination in the COVID-19 era. The current COVID-19 pandemic poses the need to take preventive evidence -based actions by policy makers with the aim of both curbing the spread of the infection and protecting people susceptible to a severe disease. In our recent article [2] we highlighted that patients with history of recent influenza or influenza like illnesses (ILI) has been found to incur greater risk and severity of COVID-19; we hypotesized that previous ILI or influenza could therefore represent a predisposing factor for subsequent COVID-19 infection. Findings of our study showed that 63.6% of 190 COVID-19 patients reported in their clinical history a recent ILI (1 -3 weeks prior to the appearance of COVID-19 related symptoms); previous flu vaccination was reported in only 26.3% of patients. To date, concerns is arising in the northern hemisphere in view of the coming soon of fall and winter seasons which are notoriously overburdened by high rates of influenza and ILIs [3] . Given these findings, we suggest policy-makers actions aimed at : 1) providing vaccinations against influenza and pneumonia: vaccination against influenza should be provided both to minimize the individual susceptibility to Covid-19 [3] and to avoid superimposed infection from influenza viruses in patients suffering from Covid-19 [4] ; moreover, as influenza and ILIs can disguise the diagnosis of COVID-19 (since they may have a similar symptomatology) flu vaccination may help disclosure COVID-19 in people suffering from SARS-CoV-2 infection.
