Actually, the mandates don’t actually end until “May 11, the same day that the COVID-19 public health emergency ends.”
The Committee to Unleash Prosperity comments:
It was clear by late 2021 that the vaccines had no meaningful effect on transmission, and that prior infection was at least as protective as vaccination. These mandates have been pure drama ever since, and the United States is among the last countries in the world to still impose them. They backfired in many ways-making many millions of Americans suspicious of Big Brother orders requiring the shots.
Late 2021 is also when omicron took over, itself basically the vaccine much of the world needed.
