COVID-19 updates: Anti-vaccine protesters halt vaccinations at Dodger Stadium

There were 152,478 new cases of COVID-19 confirmed in the United States on Wednesday, according to a real-time count kept by Johns Hopkins University.

Wednesday's case count is far less than the country's all-time high of 300,282 newly confirmed infections on Jan. 2, Johns Hopkins data shows.

An additional 3,943 fatalities from COVID-19 were registered nationwide on Wednesday, down from a peak of 4,466 new deaths on Jan. 12, according to Johns Hopkins data.

COVID-19 data may be skewed due to possible lags in reporting over the Martin Luther King Jr. Day holiday weekend.

A total of 25,598,062 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 429,195 have died, according to Johns Hopkins data. The cases include people from all 50 U.S. states, Washington, D.C., and other U.S. territories as well as repatriated citizens.

Much of the country was under lockdown by the end of March as the first wave of pandemic hit. By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up over the summer.

The numbers lingered around 40,000 to 50,000 from mid-August through early October before surging again to record levels, crossing 100,000 for the first time on Nov. 4, then reaching 200,000 on Nov. 27 before topping 300,000 on Jan. 2.

So far, the U.S. Food and Drug Administration has authorized two COVID-19 vaccines for emergency use -- one developed by U.S. pharmaceutical giant Pfizer and its German partner BioNTech, and another developed by American biotechnology company Moderna and the National Institute of Allergy and Infectious Diseases. More than 24 million vaccine doses have been administered nationwide, according to the latest data from the Centers for Disease Control and Prevention.

A draft request for assistance between the Federal Emergency Management Agency and the U.S. Department of Defense is under discussion that would seek as many as 10,000 service members to support administering COVID-19 vaccine shots up at 100 sites nationwide, according to a FEMA official who spoke on condition of anonymity because the details were not final.

A defense official, who also spoke on condition of anonymity, confirmed discussions are under way, but the final number of personnel is not settled.

It is also unclear what kind of active duty or National Guard mix it could be, and whether it includes National Guardsmen already helping in the vaccine effort around the country.

Dr. Anthony Fauci, chief medical adviser to U.S. President Joe Biden, told Fox News' "America Reports With John Roberts & Sandra Smith" that there’s no official recommendation yet on wearing double masks.

"The CDC doesn't officially recommend wearing double masks," Fauci said. "You know what would be a good start? If everybody wears at least one mask."

When Oregon health officials found themselves trapped on a road in a snowstorm, they walked car to car to administer leftover COVID-19 vaccine doses.

The staff and volunteers from Josephine County Public Health Department held a mass vaccination event at a high school Tuesday before getting trapped in the storm, they said.

"The team had six doses of COVID-19 vaccinations left to administer," but the doses would have expired before reaching their next destination, the department said.

"Not wanting to waste any doses, dedicated JCPH staff members began walking from car to car, offering stranded motorists a chance at receiving the vaccine," the department said. "In the end, all six doses were administered," including one to a sheriff’s office employee who had missed the mass vaccination event.
