JACKSON, MISS. First lady Jill Biden visited one of the states least vaccinated against COVID-19 on Tuesday, encouraging residents of Mississippi to get their shots and telling them, “The White House, our administration — we care about you.”

Mississippi and Tennessee have consistently ranked among the U.S. states with the fewest number of residents vaccinated against COVID-19, along with Alabama. Approximately 30% of Mississippi’s total population is fully vaccinated, according to the state Department of Health.

The first lady said she wanted to visit states like Mississippi and Tennessee because the current vaccination rates are “just not enough.”
