Dominic also dropped proof-of-vaccine requirements not so long ago, but surely proof-of-vaccine requirements are still permitted and maybe some businesses still require them.
In some U.S state, all Republican, proof-of-COVID-19 vaccine requirements are banned altogether. An example is Florida, under Governor Ron DeSantis, a republican who does not want discrimination in his state; "I want people to be able to live their life, whether you're gay or whether you're religious".
Apparently, he also wants people to live their lives whether or not they are vaccinated against COVID-19, and possibly whether or not they are vaccinated against any other respiratory illness as he has no problem with typical requirements for vaccines against non-respiratory illnesses such as polio and measles. Ron has also rejected implementing restrictions applying to vaccinated as well as unvaccinated people, that is, the sort of restrictions applied around the world before there was a vaccine.
Many here refuse to believe the vaccines block transmission but there is data showing the infection rates are a lot lower among the vaccinated.
