This is coming whether you like it or not. You'll have to prove you're vaccinated to get on a plane, train, bus, any other long distance transportation. Your employer may even require you to get vaccinated before you can come back to work in an office. And that may be by the federal or state guidelines, not necessarily a business decision. Swallow your conspiracy theories and your righteous indignation about losing your liberties and get the shot. Sooner you do that, the sooner we can get on with life.
The federal government can't mandate vaccinations for ppl, anymore than they can for face masks. Biden may be able to do something about how airlines run their screening procedures and make vaccinations part of TSA procedure though, i'm not sure. As for employers, i saw a video where many owners were allowing employees a choice to get vaccinated or not, but like i said before. That's all fine and dandy, until your business suddenly ends up like those meat packing plants we all heard about that became super spreader events and had to shut down because everyone got sick with covid. No business is going to risk upending their entire livelihood because they're allowing ppl the "freedom" not to be vaccinated. Imagine shutting down your office because one worker got covid, or imagine having to fight a lawsuit because a customer got covid at your establishment.
