So far, 8% of the U.S. population has received one or more doses of COVID-19 vaccines, according to official figures released Friday by the U.S. Department of Health and Human Services.

In total, 35,203,710 vaccine doses have been administered nationwide. About 27.9 million people -- 8% of the population -- have received one or more doses, while 6.9 million people -- 2% of the population -- have received two doses.

U.S. President Joe Biden's administration announced Friday that 1,110 active-duty military personnel will be deployed across the country to assist with COVID-19 vaccinations.

The announcement was made during a press briefing at the White House in Washington, D.C.

The troops, sourced from across the U.S. Army, Air Force, Navy and Marine Corps, will be split up into five teams of 222 personnel that will be assigned to support five COVID-19 vaccination centers run by the U.S. Federal Emergency Management Agency (FEMA), according to a fact sheet on the initiative released by the Office of the Secretary of Defense.

FEMA and the U.S. Department of Defense will jointly determine when the troops are no longer needed for vaccination support, according the fact sheet.

The U.S. Senate approved a budget resolution early Friday morning that would allow for the passage of President Joe Biden's $1.9 trillion COVID-19 relief package without the threat of a filibuster from Republican lawmakers who oppose it.

Vice President Kamala Harris broke a 50-50 tie in the Senate by casting a vote in favor of the Democratic measure, which was approved by the House of Representatives on Wednesday. The resolution now goes back to the House for final approval.

Biden has said he hopes to garner Republicans' support for his sweeping COVID-19 relief package, billed as the American Rescue Plan, though Democrats are working to push it through Congress with or without the GOP.

University of Oxford researchers said Friday that the COVID-19 vaccine they developed with British-Swedish pharmaceutical giant AstraZeneca remains effective against a new, more contagious variant of the novel coronavirus currently circulating in the United Kingdom.

A preprint of ongoing work to assess effectiveness of the Oxford/AstraZeneca vaccine shows that the existing version has similar efficacy against the so-called B117 variant to previously circulating variants. The preprint also describes recent analysis showing that the vaccination "results in a reduction in the duration of shedding and viral load, which may translate into a reduced transmission of the disease," according to a press release from the university.

"Data from our trials of the ChAdOx1 vaccine in the United Kingdom indicate that the vaccine not only protects against the original pandemic virus, but also protects against the novel variant, B117, which caused the surge in disease from the end of 2020 across the UK," Andrew Pollard, professor of pediatric infection and immunity at the University of Oxford and chief investigator on the Oxford vaccine trial, said in a statement.

The B117 variant was first identified last September in Kent, England, and has since spread to dozens of other countries.

"We are working with AstraZeneca to optimize the pipeline required for a strain change should one become necessary," Sarah Gilbert, professor of vaccinology at the University of Oxford and chief investigator on the Oxford vaccine trial, said in a statement. "This is the same issue that is faced by all of the vaccine developers, and we will continue to monitor the emergence of new variants that arise in readiness for a future strain change."

January marked the nation's deadliest month of the coronavirus pandemic, with a death total approximately four times the reported number of COVID-19 deaths recorded by the U.S. in any month between June and October 2020, according to an ABC News' analysis of data compiled by The COVID Tracking Project, a volunteer-run effort to track the U.S. outbreak.

In total, the virus has claimed the lives of over 440,000 people in the U.S., which translates to about 1 in every 747 Americans, according to an ABC News analysis of data collected by Johns Hopkins University.

The U.S. death toll is approximately 147 times the total lives lost during the terrorist attacks on Sept. 11, 2001, and is around 65% of the total number of deaths that were recorded nationwide during the 1918 influenza pandemic.

Although the country's seven-day average of daily COVID-19 deaths appears to be plateauing, the U.S. is still reporting an average of just over 3,100 new deaths from the disease per day, according to The COVID Tracking Project data.

More than 6 million COVID-19 infections were diagnosed nationwide during the month of January, making it the country's second-worst month of the pandemic in terms of confirmed cases, data shows.

Over the weekend, the country's cumulative tally of confirmed cases surpassed 26 million, which signifies that one in every 12 Americans has now tested positive for COVID-19. However, the national seven-day average of daily COVID-19 cases has dropped by 32.3%, the lowest average the country has seen since mid-November, according to The COVID Tracking Project data.

COVID-19 hospitalizations also continue to decline rapidly across the country. The number of COVID-19 patients currently hospitalized nationwide is the lowest since late November.

In total, more than 800,000 people have been hospitalized with COVID-19 in the U.S. since the start of the pandemic, according to The COVID Tracking Project data.
