"We have the tools to prevent this new wave of Covid from shutting down our businesses, our schools, our society as we saw happen last year," the veteran Democrat said in a speech on his administration´s new initiatives.The White House said ahead of the address that all four million federal employees and on-site contractors "will be asked to attest to their vaccination status."Those who do not declare they are fully vaccinated will be required to wear a mask on the job regardless of location, physically distance from co-workers, and be tested either once or twice a week.The moves stop short of a vaccination mandate for federal workers -- something that was being considered as the administration was mulling ways to protect federal workers and set an example for the private sector.But they mark a dramatic return to controversial restrictions that Biden had predicted would be relics of the past in June, when he proclaimed America would be able to enjoy a "summer of freedom" including more socializing and in-person celebrations.Today, with hospitalizations and infections up nationwide, Americans need to remain vigilant, Biden said."We are not fully out of the woods, because what is happening in America right now is a pandemic, a pandemic of the unvaccinated," Biden said, in words sure to antagonize some who have declined to take the shots."If in fact you are unvaccinated, you present a problem -- to yourself, to your family, and to those with whom you work."Nevertheless, the president urged citizens not to politicize the issues of vaccinations or masks."This is not about red states and blue states. It´s literally about life and death."
