COVID-19 is a test run to see how amenable populations will be to power overreaches. Media sensationalizing will help promote the annual sense of crisis and furnish justification for authorities to impose ever increasing restrictions on healthy people "in the interest of public health". Multiple (sham) studies will be widely published and reported concerning the annual cost the seasonal flu exacts on economies and individuals. The flu shot will become mandatory- and an annual certification of having received one will be a common credential requested as a condition of doing business and travelling.
Nonetheless, the vaccine's effectiveness will still only be about 25%-40% setting the stage for the recurring crisis because of "unexpected" explosion of cases involving "unusually virulent" strains and mutations. Current Inf-V (Influenza Vaccine) cards will be commonly demanded at entrances to many venues- sporting events, concerts, restaurants, bars, retail establishments, etc. In preparation for regular emergency decrees, businesses will receive designations upon being licensed- classifying them on relative scale of essential- in the event a public health emergency is declared and lock-down orders are issued.
Further, select civil "watchdogs" will be tasked with supervising the population in general and report violations to municipal and state health authorities who will assess penalties- eventually including prison time for people breaking quarantine and curfew orders without approved emergency work and travel permits. Public endangerment and violating civic curfew will become a common charge and anonymous tipsters will employ a new type of "swatting" by reporting people (some innocent) as violators, unleashing investigative teams- their membership rolls include people who want to be cops because they like having and abusing power- who employ military style tactics to force entry into private homes and perform inspections and lengthy interrogations and intrusive "medical" examinations.
Anyone objecting to this will be branded a right wing radical and Nazi sympathizer. These designations will become a part of one's searchable background information and together with "Repeated Public Health Risk" will be "just cause" for denying employment, housing, medical services, access to one's own money, etc. Public health as an issue works to soften resistance to tyranny because people see themselves and their families as vulnerable to the whims of an increasingly uncivil population that is at best indifferent to the well being of other people. They will welcome the increased government authority as necessary for their well being.
