At a roundtable discussion at the Centers for Disease Control and Prevention, CDC Director Robert Redfield said he's "optimistic that the FDA will get authorized vaccines within the next several weeks and distribution work can begin."
Vice President Mike Pence, who joined him at the meeting, added, “We are maybe, Bob, just a week and a half away from what will be the likely approval of the first coronavirus vaccine."
Pence added, "Within 48 hours from the FDA approval, we could be vaccinating people literally in all 50 states and territories all across the country."
Pence said that a vaccine won't likely be available for every American until "spring or early summer."

A new CDC report is warning that the virus "has entered a phase of high-level transmission" in the U.S. and that it's more important than ever to follow public health guidelines.
On Oct. 30, the number of new cases reported in the U.S. in a single day exceeded 100,000 for the first time, and by Dec. 2, the daily case number had nearly doubled, with over 196,000 new daily cases, the report said.
"With colder weather, more time spent indoors, the ongoing U.S. holiday season, and silent spread of disease, with approximately 50% of transmission from asymptomatic persons, the United States has entered a phase of high-level transmission where a multipronged approach to implementing all evidence-based public health strategies at both the individual and community levels is essential," the report said.
The report summarizes these strategies to combat COVID-19: universal face mask use, physical distancing, avoiding nonessential indoor space, increasing testing, prompt quarantine of exposed persons, safeguarding those at increased risk for severe illness or death, protecting essential workers, postponing travel, enhancing ventilation, hand hygiene and achieving widespread COVID-19 vaccination coverage.
