Greenberg Traurig has mandated COVID-19 vaccines for attorneys and staff in all 30 of its U.S. offices, the Am Law 100 firm told the Daily Business Review on Thursday. It joins an expanding number of major U.S. firms to mandate vaccines while other Florida-based Am Law 200 firms have yet to issue such mandates.

A firm spokesperson said individual office leaders were asked to consider mandating vaccines after the Delta variant caused a spike in case numbers and hospitalizations. The firm is nearly 90% vaccinated, the spokesperson said.
