Long covid is really rough from what I have heard. That being said if enough of the population is vaccinated you won't be seeing severe covid symptoms anymore with vaccinated people and booster shots in the future. So the virus is circulating but its affect on the population is dramatically different than 2020/mid-2021. Well that is the plan anyways. The bearish hypothesis is vaccines could not be effective against newer variants and the carnage continues, could all airplane travel be banned in this scenario? Could Lockdowns continue in perpetuity? Maybe? I really doubt this scenario as history has never seen a scenario like this, looking at previous epidemics, like the swine flu of 1918 the virus ran its course in a year and half due to immunity after infection. Given we have vaccines being deployed now this should stop the virus in its tracks after more people are being immunized.
