In recent days, Texas-based Vinson & Elkins and Florida-based Holland & Knight and Greenberg Traurig have imposed vaccine mandates, as has Lathrop GPM, which has a heavy footprint in the Midwest. The earliest firms to require COVID-19 vaccinations among employees and office visitors were based disproportionately in the Northeast and the West Coast.
