I agree that mask-wearing will not be a long term 'fashion', as soon as there is a vaccine available and enough of the population gets inoculated the danger will pass. My concern is that this novel virus may have the capacity to mutate within a rather short period of time. Currently, epidemiologists feel that COVID-19 may have been around far longer before Wuhan became an epicenter for the disease. I know several individuals, including myself, feeling some symptoms around November akin to COVID although many had received Flu vaccines in and around that time. I would like to see my blood antibody titer for any traces of COVID. That would intrigue me.
