Supply chains are a mess and truckers are a huge issue in that mess, so definitely the solution there is a vaccine mandate on the working class laborers who already hate you. This, of course only applies to people legally entering the country. Illegal immigrants are free to come without having the vaccine.
WASHINGTON (AP) — President Joe Biden will require essential, nonresident travelers crossing U.S. land borders, such as truck drivers, government and emergency response officials, to be fully vaccinated beginning on Jan. 22, the administration planned to announce Tuesday.
A senior administration official said the requirement, which the White House previewed in October, brings the rules for essential travelers in line with those that took effect earlier this month for leisure travelers when the U.S. reopened its borders to fully vaccinated individuals.
Essential travelers entering by ferry will also be required to be fully vaccinated by the same date, the official said. The official spoke to The Associated Press on the condition of anonymity to preview the announcement.
