Is Proving You Are Vaccinated a New Form of Discrimination?

In this seg­ment, Lori Duke gives a report of a Flori­da land­lord that is threat­en­ing to evict ten­ants that are not vac­ci­nat­ed. After about 18 months of hav­ing land­lords not being able to evict because non-pay­ments by renters dur­ing the COVID Pan­dem­ic, why is now okay to evict some­one because of their COVID vac­ci­na­tion sta­tus. Is this legal?
