OMICRON

The Food and Drug Administration's independent advisory committee on Thursday unanimously recommended replacing Pfizer and Moderna's original Covid vaccine used in the U.S. for everyone's first two immunizations with the new bivalent omicron shots. Instead, the drugmakers' bivalent omicron shots that target the omicron BA.5 subvariant as well as the original strain would be used for the entire vaccination series. Currently, Pfizer's and Moderna's omicron shots are only authorized as a booster, while the first two doses are still their old shots based on the original Covid strain. The FDA has proposed moving to a system that resembles how the agency updates and rolls out flu shots every year. The agency would select a Covid vaccine formulation in June to target the variant that is expected to dominate in the fall and winter.

The CDC study published Wednesday provides the first estimate of the omicron shots' real-world effectiveness against the XBB family of subvariants. For people ages 18 to 49, the omicron booster reduced the risk of mild illness by about 48% two to three months after receiving the shot. The shots provided 38% protection against mild illness for those ages 50 to 64 and 42% protection for people ages 65 and older, according to the study. They had very little protection against mild illness due to waning immunity observed with the old vaccines, Link-Gelles said. It's too early to draw conclusions about how the protection from the omicron boosters holds up over time, she said.

A preliminary study finds that seniors who received an Omicron-targeting booster shot were 81% less likely to be hospitalized with COVID-19 than those who skipped it.

The recent attempt to limit the spread of disease from China makes no sense at all.

XBB.1.5's prevalence remains highest in the Northeast, according to the CDC's latest estimates.

Yet another new and highly transmissible subvariant of the coronavirus is taking over.

The new XBB.1.5 COVID-19 mutation is popping up in new cases across the country at a concerning speed. Health experts weigh in on the latest variant of the virus.

From mental wellness to a multitude of illnesses, the past year in health and medicine has been a roller-coaster ride.

Although reports from China about this variant's characteristics are concerning, it doesn't appear to be growing too much elsewhere in the world.

U.S. health officials have focused in particular on making sure older adults stay up to date on their Covid vaccines.

The FDA on Thursday approved the use of updated COVID-19 vaccines for children younger than 5, three days after Pfizer-BioNTech applied for an emergency use authorization.

The boosters did not trigger a robust response against BQ.1.1. People with a prior history of infection who received the booster had a stronger response

Dozens of districts in major cities have now begun lifting lockdown measures despite high case numbers.

The coronavirus has continued to mutate, and two new Omicron subvariants have become dominant in the U.S., according to the CDC. The subvariants, called BQ.1 and BQ.1.1, now account for more than half of infections nationwide.

Pfizer said the booster triggered more antibodies against omicron BQ.1.1, BA.4.6, BA.2.75.2 and XBB.1 in adults older than 55 compared to the original vaccines.

Moderna’s vaccine catered to the Omicron variant produced more antibodies than the company’s original COVID shot. About 31 million U.S. citizens have received an Omicron-tailored shot.

The airport has been working with airlines and ground handlers to prepare for the busy period.

Two independent studies suggest the new Covid booster shots don't protect better against omicron BA.5 than the original vaccines.

SARS-CoV-2 is evolving "rapidly," spawning one new variant after another. But omicron continues to dominate, raising new questions about how evolution of the virus is headed.

XBB, a new version of Omicron, is evading immunity in Asia. Experts say strategic masking will help as COVID infections rise this winter.

Experts say the booster shots are to get ahead of a COVID surge before the end of the year, when more people are indoors.

The pending arrival of an Omicron booster shot marks an ambitious new phase in the nation's vaccination campaign before a possible new COVID surge.

Everyone will probably gain something from the updated vaccines. Here’s how to make the most of it.

Dr. Anthony Fauci speaks about the Omicron coronavirus variant during a press briefing at the White House in Washington, December 1, 2021. The nation's top infectious disease expert, Dr. Anthony Fauci, plans to step down from his roles running the National Institute of Allergy and Infectious Diseases and advising the White House as its chief medical advisor at the end of the year, he announced Monday. Fauci has become a household fixture during the Covid-19 pandemic, battling back misinformation, sometimes from the highest levels of government. The 81-year-old has advised seven U.S. presidents, starting with Ronald Reagan through the HIV/AIDS epidemic, West Nile virus, the 2001 anthrax attacks, pandemic influenza, various bird influenza threats, Ebola, Zika and, most recently, Covid and monkeypox. Fauci, who also runs the NIAID Laboratory of Immunoregulation, said has no intentions of retiring.

The new booster 'will become available by early to mid-September,' if the FDA and CDC authorize shots, a top White House official said this week.

Pfizer chairman and CEO Albert Bourla said he is taking Pfizer's Paxlovid pill and isolating while he recovers.

Quarantining from a sick housemate really is worth the hassle.

The conventional wisdom is that Omicron is less likely to cause serious illness, but that might have more to do with better immunity and treatments, not the virus itself.

Photo Illustration by The Daily Beast/GettyA wave of COVID infections caused by the BA.5 subvariant has crested. All over the world, daily new cases, hospitalizations and deaths are going down.But the SARS-CoV-2 virus is almost certainly here to stay. Another wave is all but inevitable as new variants and subvariants mutate, compete for dominance and find new transmission pathways.How fast that wave comes, and how bad it gets, probably comes down to a genetic competition between different mutati

U.S. regulators say they are no longer considering authorizing second COVID-19 booster shots for all adults under 50 this summer.

No one knows exactly what this will look like—only that it’s guaranteed to keep happening.

With new COVID-19 boosters expected later this year, health experts urge Californians not to put off a first or second booster shot until then.

Top U.S. health officials warned Tuesday that an expected surge in COVID-19 cases driven by the highly transmissible Omicron subvariant BA.5 has arrived, but that the country has the tools to deal with it.

Dr. Anthony Fauci said Tuesday that the Omicron BA.5 subvariant "substantially evades" antibodies from both vaccination and prior COVID-19 infection.

Compared to its ancestors, the latest Omicron subvariant, BA.5, may have an enhanced ability to create a large number of copies of the coronavirus once it gets into human cells.

A subvariant of the COVID-19 Omicron variant, BA.5, is now the dominant strain in the U.S., and its infection rates are even more harsh.

Scientists say the new variant — named BA.2.75 — appears to spread rapidly and may be able to get around immunity from vaccines and prior infection.

Omicron subvariant BA.5 is responsible for more than half of all new cases in the country, according to the CDC.

Viruses evolve, and vaccines should too. That was the big-picture takeaway from a pivotal meeting this week of the FDA’s expert advisory panel. The question before them was simple: Ahead of an expected winter surge, should vaccine manufacturers tweak their forthcoming booster shots to target Omicron, or should they stick with the tried-and-true 2020 recipe?

Advisers to the U.S. government are recommending that COVID-19 booster shots used this fall be modified to better match more recent variants of the coronavirus.

Pfizer's Omicron-only booster sparked the strongest immune response against that variant.

“Jurassic World: Dominion” dominated at the box office over Father’s Day weekend, beating out Disney’s “Toy Story” spinoff “Lightyear.” Meanwhile, "Top Gun: Maverick" is expected to earn $1 billion by July 4.

The latest version of the coronavirus is a stark reminder that the pandemic has yet to end.
