WASHINGTON—Many employers will have to ensure by Jan. 4 that their workers are vaccinated or tested weekly for Covid-19 under a set of new vaccine requirements by the Biden administration that will cover more than 80 million employees.
The requirements released Thursday by the Labor Department implement a vaccine directive that President Biden announced in September. They apply to employers with 100 or more employees. While the administration has said the requirements are necessary to curb the Covid-19 pandemic, they have drawn opposition from many Republicans.
