Comparing polio to SARS-CoV-2 is comparing apples to oranges. You can’t catch polio by sitting next to someone on a bus. It’s spread via the fecal–oral route. So, if everyone washes their hands and gets a polio vaccine, it goes away. A vaccine cannot eradicate a highly contagious virus like SARS-CoV-2(or Flu). The only way to stop it is the same way the Spanish Flu and SARS-CoV-1 were stopped — by it mutating into a highly contagious benign version that makes one immune to the pernicious versions.
Glad to hear you are OK.
