U.S. President Joe Biden has announced new vaccine mandates, that could affect up to 100 million Americans, or roughly two-thirds of the country's workers.
Biden on Thursday unveiled new measures that would require all federal workers and contractors to get vaccinated against COVID-19.
He also announced that companies with 100 or more employees should ensure that they are fully vaccinated or provide a negative test once a week.
Biden underlined that the measures are necessary, as a quarter of the adult population has yet to get a single shot.
The U.S. has also doubled fines to 500 U.S. dollars for those violating mask mandates when using public transport.
