Just weeks after he mandated federal workers get a shot or face rigorous testing and masking protocols, Biden has signed an new executive order to require vaccination for employees of the executive branch and contractors that do business with the federal government, according to a person familiar with the matter.

The step comes ahead of the president’s speech Thursday afternoon outlining a six-pronged plan to address the latest rise in coronavirus cases and the stagnating pace of COVID-19 shots.

It wasn’t immediately clear if Biden’s order includes exceptions for workers or contractors seeking religious or medical exemptions from vaccination. The person spoke on the condition of anonymity to discuss Biden’s plans before they were publicly released.

Biden is also expected to outline plans to increase virus testing in schools, in an effort to keep them open safely, amid other measures to show that his administration working to tackle the alarming rise in COVID-19 cases, which Biden has blamed for last month’s weaker-than-expected jobs report. He’s warned could further imperil the nation’s economy as some pandemic safety net protections are expiring.

Biden has encouraged COVID-19 vaccine requirements in settings likes schools, workplaces and university campuses, and the White House hopes the strengthened federal mandate will inspire more businesses to follow suit.

More than 208 million Americans have received at least one dose of a COVID-19 vaccine and 177 million are fully vaccinated, but confirmed cases of the virus have shot up in recent weeks to an average of about 140,000 per day with on average about 1,000 Americans dying from the virus daily, according to data from the Centers for Disease Control and Prevention.

Most of the spread—and the vast majority of severe illness and death—is occurring among those not yet fully vaccinated against the virus. So-called breakthrough infections in vaccinated people occur, but tend to be far less dangerous.

Federal officials are moving ahead with plans to begin administering booster shots of the mRNA vaccines to bolster protection against the more transmissible Delta variant of the virus. Last month Biden announced plans to make them available beginning on Sept. 20, but only the Pfizer vaccine will likely have received regulatory approval for a third dose by that time. Federal regulators are seeking additional data from Moderna that will likely delay its booster approval until October.

Officials are aiming to administer the booster shots about eight months after the second dose of the two-dose vaccines.
