I don't think it's a given that there'll be a next flu season. In my jurisdiction, I calculated that we've reduced the incidence of cold/flu symptoms by about an order of magnitude with social distancing measures. (Based on normal incidence of cold/flu symptoms, and rate of covid-19 testing which is open to anyone with cold/flu symptoms.) Note also that the herculean effort to reduce all other cold/flu viruses by an order of magnitude only reduced R of covid-19 to around 1.
