The flu has a vaccine and still kills 80k in a bad flu year. So, looks like by your standards, we will stay in shut down purgatory forever.
Life has risks, no way to eliminate risk 100%. But when the survival rate without a vaccine is 99.5%+ for the majority of the population then its time to get everyone back work.
Fill up the sports stadiums, open up the movie theaters and move on. Follow Sweden’s lead. These shut downs are ridiculous. But you can stay home if you feel that’s what’s best for you personally.
