Will a “vaccine passport” become a requirement?

U-S representatives in South Carolina are imploring the state’s governor to do what he can to forbid the idea of “vaccine passports” taking hold in the state.  It’s a concern not only confined to South Carolina, but in other states, as well, where there’s concern that travel groups might insist travelers prove that they’ve been inoculated against COVID-19.  Among those who are behind a letter sent to Governor McMaster is the Third District representative, Jeff Duncan of Laurens.
