What a mess. Given that we’re under a new administration that would presumably be more reluctant to impose travel bans, perhaps those vaccines should be offered to the general public.
Better to give vaccines to the Border agents, ICE, Immigration, and Homeland Security officers (DHS),
who are more likely than most to run into infected migrants under normal working conditions.
They are all our 'first line of defense' for infectious diseases coming into the country, regardless of which administration controls the border.
