As I noted elsewhere, in many jurisdictions it is, as is testing.
In fact, as the very article upon which you are commenting notes, under the new OSHA rules those who do not want to get vaccinated can simply take a test once a week instead!
I admit, some mornings I have a bit of dry mouth, but after my morning coffee I always have enough spit to hock a loogie into a cup. For science and the greater good.
