Joe Biden is set to address the nation Tuesday with a stark warning for unvaccinated people

Joe Biden is to address the nation Tuesday to outline extra steps he will take to deal with the Omicron coronaviruses variant and deliver a "stark warning" to people who remained unvaccinated.

The president will announce new steps the Administration is taking to help communities in need of assistance, while also issuing a stark warning of what the winter will look like for Americans that choose to remain unvaccinated, said Jen Psaki on Saturday.

The president will detail how we will respond to the challenge.

He will remind Americans that they can protect themselves from severe illness by getting their booster shot when they are eligible.

The White House has changed their messaging. More than 200 million Americans have had at least one dose of a vaccine as of December 16.

The seven-day average of daily cases was up from December 1 to December 18. The Omicron variant drove case surge in other countries.

According to early data, Omicron may be more transmissible but cause less severe illness than other coronaviruses.

The Centers for Disease Control and Prevention predicts that there will be more than 40,000 deaths in the US by January 8, with its latest model.

The state of New York reported 21,027 new COVID-19 cases in a single day.

Boosters for all adults and expanded at- home testing were some of the extra measures outlined by Biden.

Vice President Harris said the administration didn't see the Delta or Omicron variant coming.

She told the Los Angeles Times that they didn't see Delta coming. Most scientists didn't see Delta coming because of their advice and direction.

We didn't see Omicron coming. This awful virus has been, as it turns out, has different types of genes.
