Jan. 4: Companies with 100 or more employees must ensure either that their workers are fully vaccinated by this date or that they test negative for the coronavirus at least once a week.

Jan: 4: Health care workers are required to be vaccinated by the same deadline but with no option for weekly testing in lieu of vaccination. The rule covers all employees — clinical and nonclinical that receive federal funding from Medicare or Medicaid.

Nov. 22: The deadline for federal employees to be vaccinated. There is no testing option. Federal contractors have until Jan. 4.
