The Department of Homeland Security has announced amendments to Title 19 regulations in two phases.  First, beginning in November, U.S. Customs and Border Protection will begin to allow fully vaccinated visitors to enter the U.S. from Mexico and Canada for non-essential purposes via land and ferry border ports of entry. Second, beginning in early January 2022, all foreign national travelers crossing land or ferry ports of entry will be required to be fully vaccinated for COVID-19 and to provide proof of vaccination, whether they are entering the U.S. for essential or non-essential reasons. Secretary Mayorkas to Allow Fully Vaccinated Travelers from Canada and Mexico to Enter U.S. at Land Borders and Ferry Crossings | Homeland Security (dhs.gov)
