President Biden issued a strong warning to those unvaccinated while unveiling "six-pronged strategy" to stop the spread of COVID-19 and get more Americans vaccinated. "Listen to the voices of unvaccinated Americans who are lying in hospital beds, taking their final breath saying, 'if only I'd gotten vaccinated. If only.' It's a tragedy. Please don't let it become yours," Biden said. In this new strategy, Biden will require businesses with more than 100 employees to ensure their workers are vaccinated or tested weekly. He will also mandate vaccine requirements for health care providers that receive Medicare and Medicaid funding and for teachers and staff at federal programs like Head Start and schools run by the Department of Defense and Bureau of Indian Education. In total, the new plan is expected to affect about 100 million workers in the U.S.
