There’s signs a new way of nudging unvaccinated workers into COVID-19 shots may be working.

It’s been two weeks since Delta Air Lines DAL, +3.63% said it would start giving unvaccinated workers $200 monthly surcharges and the airline is already seeing the announcement move the needle on its internal vaccination rate, according to its top medical official.

In the brief span of time, the company’s vaccination rate climbed to 78% from 74%, Dr. Henry Ting, senior vice president and chief health officer at Delta said Thursday.

A Florida judge ruled Wednesday that the state cannot enforce a ban on public schools mandating the use of masks to guard against the coronavirus, while an appeals court sorts out whether the ban is ultimately legal.

Leon County Circuit Judge John C. Cooper lifted an automatic stay of his decision last week that Republican Gov. Ron DeSantis and state education officials exceeded their authority by imposing the blanket ban through executive order and tagging defiant pro-mask local school boards with financial penalties.
