“Mandates are working,” said John Swartzberg, a physician and professor at the School of Public Health at the University of California, Berkeley. “If you define ‘working’ by the percentage of people getting vaccinated and not leaving their jobs in droves.”
Unlike other incentives — “prizes, perks, doughnuts, beer, we’ve seen just about everything offered to get people vaccinated” — mandates are among the few levers that historically have been effective in increasing compliance, said Dr. Swartzberg, who has tracked national efforts to increase rates of inoculation.
The various mandates in place are arriving as many employers await further guidance from the Biden administration, which announced sweeping actions in September, including a mandate that all companies with more than 100 workers require vaccination or weekly testing. Mr. Biden also moved to mandate shots for health care workers, federal contractors and a vast majority of federal workers, who could face disciplinary measures if they refuse.
