U.S. health authorities said Thursday that 16- and 17-year-olds should get a booster dose of Pfizer's COVID-19 vaccine once they're six months past their last shot.

The U.S. and many other nations already were urging adults to get booster shots to pump up immunity that can wane months after vaccination, calls that intensified with the discovery of the worrisome new omicron variant.

On Thursday, the Food and Drug Administration gave emergency authorization for 16- and 17-year-olds to get a third dose of the vaccine made by Pfizer and its partner BioNTech. And hours later, the Centers for Disease Control and Prevention lifted the last barrier — saying those teens should get their booster as soon as it's time.

CDC Director Rochelle Walensky told The Associated Press the boosters are important considering that protection against infection wanes over time and “we’re facing a variant that has the potential to require more immunity to be protected.”

“Vaccination and getting a booster when eligible, along with other preventive measures like masking and avoiding large crowds and poorly ventilated spaces, remain our most effective methods for fighting COVID-19,” Dr. Janet Woodcock, acting FDA commissioner, said in a statement.

The Pfizer vaccine is the only option in the U.S. for anyone younger than 18, either for initial vaccination or for use as a booster. It’s not yet clear if or when teens younger than 16 might need a third Pfizer dose.

Vaccinations for children as young as 5 just began last month, using special low-dose Pfizer shots. By this week, about 5 million 5- to 11-year-olds had gotten a first dose.

The extra-contagious delta variant is causing nearly all COVID-19 infections in the U.S., and in much of the world. It’s not yet clear how vaccines will hold up against the new and markedly different omicron mutant. But there’s strong evidence that boosters offer a jump in protection against delta-caused infections, currently the biggest threat.

Complicating the decision to extend boosters to 16- and 17-year-olds is that the Pfizer shot -- and a similar vaccine made by Moderna -- have been linked to a rare side effect. Called myocarditis, it’s a type of heart inflammation seen mostly in younger men and teen boys.

The FDA said rising COVID-19 cases in the U.S. mean the benefits of boosters greatly outweighed the potential risk from the rare side effect, especially as the coronavirus itself can cause more serious heart inflammation.

Health officials in Israel, which already gives boosters to teens, have said the side effect continues to be rare with third doses.

A U.S. study this week offered additional reassurance. Researchers from children’s hospitals around the country checked medical records and found the rare side effect usually is mild and people recover quickly. The research was published Monday in the journal Circulation.

Elizabeth Holmes Awaits Jury's Verdict in Day 6 of Deliberations
Jurors in the trial against Theranos CEO Elizabeth Holmes have entered day six of deliberations. Holmes is accused of lying to investors about the functionality of a newly developed blood-testing technology. Andrew George, partner at Baker Botts, joined Cheddar to break down key points in the case and what the jury might be considering during their deliberations. He also noted that the rest of Silicon Valley, including Holmes' business partner, Ramesh "Sunny" Balwani, who is facing identical charges, is closely watching the outcome of deliberations — as it could set the tone for future regulations and Balwani's own trial.
Wildfires Out In The West Impacting California's Carbon Cap-and-Trade Program
According to researchers, the state of California's cap-and-trade program is currently being undermined by forest fires caused primarily by climate change. Over the past few years, trees that were set aside for the program have been releasing carbon as they continue to burn in fires. Climate Researcher and Policy Director at CarbonPlan Danny Cullenward, joined Cheddar to discuss more.
How the CDC Decided to Shorten COVID Quarantines
The CDC's latest update to its COVID-19 quarantine guidelines reduces the isolation period from ten days to just five for people who test positive but are asymptomatic. Dr. Bayo Curry-Winchell, regional clinical director at Carbon Health, spoke to Cheddar's Baker Machado about the new guidance. She noted that while the reduced quarantine time "makes sense," the CDC should also require that a person test negative after their quarantine and before interacting with the public. "There is science behind it. We know that the majority of illness happens, or transmission, one to two days before the onset of symptoms and then two to three days as you have symptoms. So there is science behind the reducement of the actual five days," she said.
Gas Prices to Rise in 2022 amid Soaring Demand, Omicron Spread
Prices at the pump this year reached a seven-year high, and a new forecast from GasBuddy shared with CNN predicts that gas prices will only continue to rise in 2022 and that the national average could even reach $4.00 a gallon; however, analysts at GasBuddy say anything could happen when it comes to gas prices in the future, as the pandemic has made it difficult to make any predictions about the economy. Consumer Energy Alliance federal policy advisor Michael Zehr joins Cheddar News' Closing Bell to discuss.

New COVID-19 Cases in U.S. Hit Highest Numbers Since January
As 2021 winds down, the number of positive COVID-19 cases has surged dramatically with numbers not seen since the heights of the pandemic. Dr. Laolu Fayanju, the regional medical director at primary care provider Oak Street Health, joined Cheddar to discuss the numbers, how the healthcare system is handling the surge this time around, and what it means that the CDC just cut the quarantine time guideline in half for those who are infected. "These are incredibly high numbers because they reflect the transmissibility of the omicron variant," Fayanju said.
