US President, Joe Biden has announced new Covid-19 measures that require workers at large companies to be vaccinated or face weekly testing.
The measures include a vaccine mandate for millions of federal government workers
The order will affect about 80 million workers.
In an address at the White House on Thursday, Mr Biden directed the US Department of Labor to require all private businesses with 100 or more staff to mandate the jab or request proof of a negative coronavirus test from employees at least once a week.
The president had promised a “summer of freedom” from the virus, but the Delta variant has seen infections surge.
“This is not about freedom, or personal choice, it’s about protecting yourself and those around you,” the president said as he unveiled the six-point plan.
Nearly 17 million other healthcare workers at facilities receiving federal benefits will also face the same requirements, he said.
Over 650,000 Americans have died with Covid-19 and hospitals are at capacity.
