One of my big fears is that this is coming. People have been emboldened and received very little pushback against forcing others to get the covid vaccine, and to prove it wherever they go. How long until we start hearing "flu vaccine saves lives, I have the right to know if someone around me isnt vaccinated, etc etc". I'm almost afraid to say it out loud, and I bet a lot of people here already support it.
Childhood vaccination against Polio and the other big and previously debilitating childhood illnesses is nothing like mandating a covid vaccine, especially during a live event where the guidance and effectiveness is changing daily.
