Despite the broad scope of the president’s push, most U.S. workers, more than 80 million, will still have the option of proving they are not carrying the virus by submitting to weekly Covid tests.

To boost the pace of daily shots, which have slowed down after a spike in mid-August, the president ordered the Department of Labor to create a new rule requiring any company with more than 100 employees to mandate vaccines for their employees or weekly Covid tests for workers who cite religious or health reasons for not getting vaccinated. However, those reasons for opting out are likely to be more scrutinized by employers going forward.

The new rule will be implemented by the Labor Department’s Occupational Safety and Health Administration, or OSHA. OSHA can issue an emergency temporary standard if it proves that employees are in danger and that the proposed rule can avert that danger.

Employers will also be ordered to provide paid time off for employees to get vaccinated. This applies to both the public and private sectors.

“No one should lose pay in order to get vaccinated or take a loved one to get vaccinated,” Biden said.

In his announcement, Biden questioned why 80 million Americans have still not received the shots after they were made free and accessible and were approved by the Food and Drug Administration.

“What more is there to wait for? What more is there to see?” Biden said. “We’ve been patient, but our patience is wearing thin.”

Biden appealed to those running large entertainment venues, sports arenas and movie theaters to require vaccination or proof of a negative test for entry. New York City and San Francisco already require proof of vaccination for activities such as dining indoors and attending movies and entertainment venues, with New York City requiring proof of at least one dose and San Francisco requiring proof of full vaccination.

Biden also asked physicians across the country to “reach out to unvaccinated patients … and make a personal appeal to them to get the shot.”

About 75% of U.S. adults have received at least one dose of a Covid vaccine and about 54% of all Americans are fully vaccinated, according to Centers for Disease Control and Prevention data. Experts are still split on what percentage of a population needs to be vaccinated in order for the population to reach herd immunity, though estimates range between 70% and 90%.

“This is not about freedom or personal choice. It’s about protecting yourself and those around you,” Biden said.
