President Joe Biden laid out hopeful new steps Monday to expand coronavirus vaccinations but also echoed the stern warnings of a top public health official who told Americans she has a recurring feeling of “impending doom” that a fourth wave of the virus may be on its way.

“We still are in a war with this deadly virus and we"re bolstering our defenses, but this war is far from won. Together, we have so much to be proud of in the past three weeks, passed more than three weeks, past 10 weeks. We also have so much to be sorrowful about.

Nearly 1,000 Americans a day are still dying from COVID-19 as we approach 550,000 deaths in a single year”, - he said.

The president addressed the nation from the White House Monday, declaring, “if we let our guard down now, we can see the virus getting worse, not better. People are letting up on precautions, which is a very bad thing”.
