DONT FORGET The vaccine will be somewhat effective not 100% and 50% of people wont take it . This technology will still be needed in senior buildings , airlines , restaurants, schools , the fear of the Virus wont go away im sorry i dont see it happening although i wish it would even if it means me loosing major $$ but for the benifit of all mankind this needs to go away ! The reality is it will get better but never go away .. ! My 2 cents ... have a great day all !!!
