Take a look at the graph at the bottom of this page:

Each data point represents results of a seroprevalence (antibody) study. If you hover over the datapoints you'll see more info about each study.
As I understand it, if you've gotten the vaccination, you should test positive for antibodies to the spike protein. These are the light orange points on the graph. As of November, 2021, around 88% to 98% of Americans exhibited seroprevalence for the spike protein, depending on the study.
If you've been infected, you'll likely test positive for both nucleocapsid and spike proteins. Those results appear on the graph too.
So in November, 2021, the percentage of Americans with immunity from previous infection and vaccination probably exceeded 90%. What's happened since then? An Omicron wave that infected more Americans than any of the previous waves. Over 95% of Americans now probably have protection because of vaccinations and infection. Vaccine mandates don't really matter, because many of those who've been infected have better immunity than those who've only been vaccinated.
The Supreme Court has struck down Biden's proposed vaccine mandate for private businesses. The vaccine mandate for federal employees is now on hold because of court rulings. The Biden administration would have to get a favorable Supreme Court to remove the hold, and it's doubtful they'll try that.
Only six states now have mask mandates, California, Hawaii, Illinois, New Mexico, Oregon and Washington. I can't think of anyone on this board who hails from one of those states and who opposes mask mandates.
So why are CNN, MSNBC, Fox, and many politicians still howling about this? Answer: to sell commercials and raise money for PAC's. As a wise man, Salty Again, said, it doesn't matter any more. We can argue for the sake of arguing, and I'm as guilty of that as anyone here. But at this point this just serves to divide us. It's time to go back to worrying about real problems, like the national debt.
