The Food and Drug Administration is reportedly poised to authorize a third dose of the Pfizer-BioNTech coronavirus vaccine for kids ages 12-15.

Regulators also plan to allow adolescents and adults to get the third shots five months after receiving the second dose of the Pfizers vaccine instead of the current six months, The New York Times reported, citing sources it described as familiar with the agency's deliberations. A third shot, often referred to as a booster, is also expected to be authorized for children as young as 5 with immune deficiencies.

The third dose authorization is expected "in coming days,"CNN reported, citing a source CNN said was familiar with the plan.The Times said the authorization is expected Monday.

"As the booster is already authorized for 16 and over, we are confident regulators are making every effort to look for ways to preserve a high level of protection against the virus across broad populations," Pfizer said in an email to USA TODAY.

The Centers for Disease Control and Preventions vaccine advisory committee is expected to meet next week to vote on whether to recommend the changes, the Times said. If the panel agrees, CDC director Dr. RochelleWalensky is expected to sign off immediately.

A third shot could help ease the health threat faced by millions of middle school and high school students returning to classrooms next week after the holiday break. During that break an omicron-fueled surge has driven reported daily infections across the nation to record levels.

Almost 62% of all Americans are "fully vaccinated" two shots of Pfizer or Moderna shots or one of Johnson & Johnson but only about one-third of all Americans have received a booster,according to the CDC.At least 1.8 million12- to15-years-old have tested positive for the virus,according to the CDC.

The Centers for Disease Control and Prevention on Thursday warned travelers against taking cruises as clusters of COVID-19 cases increase on the ships with the emergence of the omicron variant. FromNov. 30 toDec. 14, cruise ships operating in U.S. watersreported 162 cases of COVID-19 to the CDC. FromDec. 15 toDec. 29, cruise ships sailing in U.S. waters reported 5,013 COVID-19 casesto the CDC.

"Today, CDC increased theCruise Travel Health Notice to a Level 4, recommending people avoid cruise travel regardless of vaccination status," the CDC said in a statement.

Cruise Lines International Association, the leading industry organization, said it was "disappointed" with the CDC's decision, saying it was "particularly perplexing considering that cases identified on cruise ships consistently make up a very slim minority of the total population onboard ... and the majority of those cases are asymptomatic or mild in nature."

The United States is averaging more than 300,000 new reported coronavirus cases per day for the first time, although hospitalizationnumbers are somewhat less gloomy.

AUSA TODAY analysis of Johns Hopkins University data shows the country reported 2.11 million cases in the seven-day period ending Wednesday, an increase of 82% over the previous week as the omicron variant, holiday gatherings and frenzied testing helped push numbers higher.

Forty-sevenstates show rising case counts and 15states reported their highest-ever counts: Connecticut, Delaware, Florida, Georgia, Hawaii, Illinois, Maryland, Massachusetts, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Virginia and WashingtonandPuerto Rico.

The national pace of hospital admissions for likely COVID-19 patients was up 20.7% from a week earlier, alarming but far lower than the jump in infections. Experts say early data indicatesomicron might not be as severe as previous variants. That andtherise in vaccinated Americans havehad an impact the number of Americans now in the hospital with COVID-19 is running at around 65,000, or about half the number in January, theCenters for Disease Control and Preventionreported.

And Dr. Anthony Fauci saidthe average stay during the current surge at a major South African hospital is about four days, down from 8.8 days in previous surges. The numbers are similar to other preliminary reports, Fauci said.

"The pattern and disparity between cases and hospitalization strongly suggests that there will be a lower hospitalization to case ratio when the situation becomes more clear," Fauci said.

Thousands moreU.S.flights have been canceled or delayed Thursday,according toFlightAware, which tracks flight status.

New York City is forging ahead with modified plans for its annual New Year's Eve ball drop in Times Square on Friday despite record numbers of COVID-19 cases across the city and nationwide.In 2020, revelers were banned from thecelebration as a result of the pandemic, and only essential workers, media members and police were atTimes Square as the ball dropped.This year,the citywill require revelersto show proof of vaccination and photo ID and to wear masks.The event normally hosts 58,000 people, but this year will be limited to about 15,000 attendees and won't allow entry until 3 p.m. ET,de Blasio announced last week.

"We want to show that were moving forward, and we want to show the world that New York City is fighting our way through this,"Mayor Bill de Blasio said Thursday on NBC'sTODAY Show.

The number of people in the hospital with COVID-19 has reached a pandemic record high in Ohio, and Gov. Mike DeWine has ordered additional members of the state National Guard into hospitals to help with the surge.Ohio had 5,356 people in the hospital with the coronavirus Wednesday the highest per-capita hospitalization rate in the country, said Robert Wylie, chief medical operations officer at the Cleveland Clinic.More than nine of every 10 people hospitalized with COVID-19 since June have been unvaccinated, DeWine said.

If youre vaccinated, the chances of you ending up in the hospital are pretty darn slim, he said.

Federal officials are defending theCenters for Disease Control and Prevention's decision to cut to five days from 10 days the amount of recommended time people should isolate after testing positive for the coronavirus. Some have rejoiced in the shortened isolation period, while others have criticized the decision, arguing the CDC turned its back on science and bowed to business interests.

The announcement came days after Delta Airline's CEO publicly asked the CDC for a shorter isolation period, and in the midst of thousands of canceled flights, which airlines have blamed on staffing shortages because ofthe latest surge in coronavirus infections.

CDC Director Rochelle Walensky said the new recommendation is backed by science. The most amount of COVID-19 transmission happens in the one or two days prior to developing symptoms and in the two to three days after developing symptoms, Walensky said totaling five days.The decision is backed by behavioral science, too, she said.

It really had a lot to do with what we thought people would be able to tolerate, Walensky told CNN'sKaitlan Collins.

Some professional associations have pushed back on the new guidelines, saying they'll be harmful to workers. The American Nurses Associationurged the CDC to reconsider its decision,saying guidance "is especially problematic when reliable testing is not widely available, and particularly difficult to access in places experiencing surge conditions."

Dr. Anthony Fauci, the nations top infectious disease expert, warned Americans to stay away from large-scale New Years parties and opt for small gatherings with vaccinated and boosted people.

If you were in a situation with a family setting, in your home, with family parents, children, grandparents and everyone is vaccinated and boosted, although the risk is never zero in anything, the risk is low enough that we feel you should continue to go through with those plans, Fauci said during a news briefing Wednesday.

Cities around the world have canceled their large New Years Eve celebrations amid the rapid spread of the omicron variant of the coronavirus. New York City put an attendance cap of 15,000 on its annual Times Squareparty and will require proof of vaccination. Events in Los Angeles and Seattle have also been canceled.

If your plans are to go to a 40- or 50-person New Years Eve party with all the bells and whistles and everybody hugging and kissing and wishing each other a Happy New Year, I would strongly recommend that this year we do not do that, Fauci said.

"We are moving closer to a safe reopening of school next week," Michael Mulgrew, head of the United Federation of Teachers in New York City schools, said."But we arenot there yet."

Testing positive for COVID-19 starts a confusing, disruptive and at times frightening process one that millions of Americans will likely go through in the coming week.

First, you need to isolate. Thats a more intense version of quarantining it means cutting off contact with other people as much as possibleso you reduce the chanceof infecting them. Thisalso means forgoing travel, not going to work and even limiting contact with people in your own household who aren't infected.

The CDC says isolating is a necessary step whether youre vaccinated or unvaccinated, and whether you havesymptoms or feelfine.

Everyone who tests positive for COVID-19 should monitor their symptoms. And people who are unvaccinated or at high risk for severe disease should be extra-vigilant for symptoms that might require emergency care. Call your doctor for early treatment options.

How long should you isolate? How long will I be contagious?What if you are in close contact with someone who tested positive?Hereswhat you should know about omicron and COVID-19 this holiday season.
