The U.S. Army's new vaccine offers ‘broad protection’ against current and future COVID variants

Rsearchers at Walter Reed Emerging Infectious Diseases Branch develop a new COVID-19 vaccine.

The number of average weekly COVID-19 cases in the U.S. has more than doubled since November 28 due to the spread of the new omicron variant. The increase has many worried that it’ll be another deadly winter in the U.S., especially for the unvaccinated.

President Biden had a dire warning for the unvaccinated this week saying they face a winter of "severe illness and death."

As our exhausted populace prepares to fight through another tough winter, there is good news on the horizon, courtesy of the U.S. Army. Recently published preclinical study results show that a new vaccine, known as the Spike Ferritin Nanoparticle (SpFN) COVID-19 developed by researchers at the Walter Reed Army Institute of Research, provides “a potent immune response” and “broad protection” against COVID-19 variants and other coronaviruses.

The vaccine was developed as part of a strategy to address the current variants as well as those that could emerge in the future.

“The accelerating emergence of human coronaviruses throughout the past two decades and the rise of SARS-CoV-2 variants, including most recently Omicron, underscore the continued need for next-generation preemptive vaccines that confer broad protection against coronavirus diseases,” Dr. Kayvon Modjarrad, Director of the Emerging Infectious Diseases Branch at WRAIR and co-inventor of the vaccine, told the U.S. Army. “Our strategy has been to develop a ‘pan-coronavirus’ vaccine technology that could potentially offer safe, effective and durable protection against multiple coronavirus strains and species.”

If the vaccine is approved by the FDA, it could act as a one-size-fits-all shot against current and future variants.

The new vaccine will have to undergo Phase 2 and Phase 3 trials before it is approved for public use. The next step for researchers is to see how the new pan-coronavirus vaccine works on those who haven’t been vaccinated nor previously infected with COVID-19.

“We need to evaluate it in the real-world setting and try to understand how does the vaccine perform in much larger numbers of individuals who have already been vaccinated with something else initially…or already been sick,” Modjarrad said.

“It's very exciting to get to this point for our entire team and I think for the entire Army as well,” Modjarrad told Defense One.

News of the Army’s new vaccine comes as the FDA announced on Wednesday that it has approved a new anti-COVID pill by Pfizer. In clinical trials the Paxlovid treatment "reduced risk of hospitalization or death by 89% (within three days of symptom onset) and 88% (within five days of symptom onset) compared to placebo; no deaths compared to placebo in non-hospitalized, high-risk adults with COVID-19."

The Biden administration has paid Pfizer $5 billion for 10 million courses of the Paxlovid treatment and 65,000 courses of the treatment are expected to be delivered next week. According to The New York Times, Pfizer will be able to supply 200,000 courses of the treatment in January and 150,000 more in February.

Homeless man catches family's two children and dogs dropped from burning apartment building

"He was right underneath and he was like 'Yes, throw your daughters out, I'm going to catch them, I'm going to get them.'"

CBS News|YouTube

Man catches entire family as they jump from burning building.

House fires are devastating for families. In a matter of minutes, you could lose all of your belongings and a place to live, or worse, you could lose loved ones. A family in Phoenix, Arizona, recently found themselves facing the reality of their own home in flames. Claudia Jimenez told CBS News that she woke up trapped in her burning apartment with her two daughters, with nothing to do but yell for help in the hopes that someone would hear her.

The mom's screams were answered by Joe Hollins, a homeless man who was camping nearby with his wife. Hollins didn't hesitate to try to find a way to help. With no way out and the fire department still nowhere on the scene, Jimenez had to trust the stranger who was standing below.

"He was right underneath and he was like 'Yes, throw your daughters out, I'm going to catch them, I'm going to get them,'" Jimenez told CBS.

Man rewatches shows from his childhood and his recaps of the bonkers storylines are priceless

Rob Anderson's hilarious recaps of shows like "Mighty Ducks," "Beethoven," and "7th Heaven" might make you wonder how they got made in the first place.

These plots makes zero sense.

While there are no doubt some timeless classics from our childhood that remain every bit as amazing as we remember, many are straight-up cringey upon a later viewing. Really, it’s to be expected as societal viewpoints change…sort of a marker of how far we’ve collectively come.

And so, what do we do with these problematic pieces of old-school pop culture? Well, we can certainly update them to better reflect a more modern attitude, but that also comes with a set of potential problems. Or we could simply never watch them again. Certainly an option given all the content out there. But then we might miss an opportunity to better understand what seemed to work for the mainstream then, and why it doesn’t work now.

And then there’s the third option—allow ourselves to be entertained by their cringiness.

That’s certainly the route taken by Rob Anderson. Over on TikTok, Anderson has taken ultra-popular movies and television shows from his childhood and given them hilarious recaps capturing how absurd some of the storylines are.

A mom who admitted she packs her 2-year-old a meal when they go out to dinner has started an interesting debate on TikTok about restaurant etiquette and how it applies to young children.

“Call me cheap, call me whatever, but if we’re going out to a restaurant, I’m packing my kid a meal," Smith, 21, said in her post. "I do this for many reasons. On Friday nights, my family and I get together, and tonight, we’re getting food out. My son is not getting food out.”

Woman decides that she is the love of her life and marries herself at her retirement home

“I said, you know what, I’ve done everything else. Why not?”

KCEN|YouTube

77-year-old woman decides she's the love of her life and marries herself.

We joke about marrying ourselves or a platonic friend if some arbitrary amount of time has passed without a proposal from an imaginary suitor. And sure, some people do wind up marrying a friend in more of a business arrangement, but it's not very common that someone follows through with marrying themselves.

Dorothy "Dottie" Fideli, decided that she was going to break the mold. The 77-year-old sat down and thought about all of the things she had done in life and who was with her the entire time cheering her on. It was an easy answer: herself. She was her biggest cheerleader, the person who always showed up and the love of her life, so Fideli made the plan to marry herself.

On a beautiful May day, friends and family gathered in the O’Bannon Terrace Retirement Community, where Fideli is a resident, to witness the ceremony.

12-year-old Texas girl saves her family from carbon monoxide poisoning

She knew something was wrong with her mom and brother, which wound up saving her whole family.

WFAA|YouTube

Fort Worth 12-year-old helps save family from carbon monoxide poisoning.

Carbon monoxide is called a silent killer for a reason. Many people don't realize they're experiencing carbon monoxide poisoning before it's too late. The gas is colorless and odorless and tends to have a sedating effect that causes people to sleep through the fatal poisoning. Having carbon monoxide detectors is one of the most effective ways to identify the gas before it's too late to get out of the house, but not every home has one.

A little girl in Fort Worth, Texas, experienced a terrifying encounter with the deadly gas, but her quick actions saved her entire family. Jaziyah Parker is being held up as a hero after she realized something was wrong with her family members and called for help.

The girl called 911 after she noticed her mom pass out. On the call with the dispatcher, Jaziyah says she thinks her mother has died before explaining that there was something now wrong with her baby brother, who was just 5-months-old.

Drew Barrymore speaks during the FLOWER Beauty launch at Westfield Parramatta on April 13, 2019, in Sydney, Australia.

Drew Barrymore, 48, has been in the public consciousness since she starred as Gertie in 1982’s mega-blockbuster, “E.T.: The Extra-Terrestrial,” a performance that earned her an Oscar nomination for Best Supporting Actress. So, it makes sense that many people of a certain age feel as if they’ve grown up with her.

Barrymore has consistently starred in hit films and movies that are rewatchable cable-TV staples, such as “Charlie's Angels” (2000), “Never Been Kissed” (1999), “Scream” (1996), “The Wedding Singer” (1998), “50 First Dates” (2004) and “Fever Pitch” (2005).

Now, she’s an even more significant part of people’s lives as the host of “The Drew Barrymore Show,” which runs every weekday on CBS. So far, the show has been a big success, attracting an average of 1.21 million views per show, and ranks as the #4 talk show in syndication. It was recently renewed through the 2024 season.
