Gov. Ron DeSantis said Monday he will expand COVID-19 vaccinations to law-enforcement officers, firefighters and K-12 teachers who are age 50 or older.

DeSantis told reporters he would issue an executive order later Monday that will mark an additional expansion of vaccinations that have focused since late December on people age 65 or older.

After focusing almost exclusively since December on vaccinating seniors, Gov. Ron DeSantis has cleared the way for more people under age 65 to receive shots if they are “extremely vulnerable” to COVID-19.

Marking a significant change in Florida’s vaccination strategy, Gov. Ron DeSantis on Tuesday said teachers and law enforcement officers ages 50 and older will have access to COVID-19 vaccine doses in the coming days as four federally supported vaccination sites open in the state.
