I see the Cabal as trying to push it....but will probably get a lot of flack over it.I know you didn't. But I don't see it as a precursor, either. Sorry for not being clearer.
If vaccine passports do become necessary, I think it will be only for travelling overseas, or on cruise ships. I don't see it happening here that only vaccinated people be allowed into stores. Store owners would lose too much business. Also, store owners themselves wouldn't have to get the vaccine.
