FDA backs second omicron booster for high-risk groups 2023-04-18T04:00:00Z While newer omicron cousins now are circulating, recent studies show the bivalent shots still are effective. Extra spring COVID booster cleared for certain Americans 2023-04-18T04:00:00Z The bivalent vaccines rolled out last fall as a booster dose and consist of half the original recipe and half protection against the BA.4 and BA.5 versions of omicron. NOT REAL NEWS: A look at what didn’t happen this week 2023-04-21T04:00:00Z Hence, variants like delta and gamma made headlines when they emerged and began to spread — but the WHO has yet to assign any variants a new Greek name since omicron surged in late 2021. The COVID virus has mutated so much since 2019 that some experts say it should be renamed SARS-CoV-3 2023-04-13T04:00:00Z Some anxious patients have been “really clamoring” for a second omicron booster, said Camille Kotton, clinical director for transplant and immunocompromised host infectious diseases at Massachusetts General Hospital in Boston. FDA to okay second omicron-targeting booster for some, officials say 2023-04-03T04:00:00Z Another omicron descendant, XBB.1.16, which is called Arcturus and is spreading rapidly in India, is responsible for about 7 percent of U.S. cases.

How the U.S. tossed in the towel and fell behind Europe during the COVID-19 pandemic 2023-04-01T04:00:00Z For months, the single-most common question I have received from readers has been when they can get a second bivalent dose, which targets the omicron strain and its subvariants. Opinion | Vulnerable people should be allowed a second bivalent shot this spring 2023-03-28T04:00:00Z Instead, we have this alphabet soup of named variants, all of which are technically different sub-strains of omicron. The COVID virus has mutated so much since 2019 that some experts say it should be renamed SARS-CoV-3 2023-04-13T04:00:00Z They noted they are not advocating the second omicron booster for young people, who might experience rare heart-related side effects.

U.S. fell behind Europe, put adults before kids with school shutdowns, experts say 2023-03-28T04:00:00Z And reinfection protection was shown to be “substantially lower” for omicron variants, which have been the dominant strains in the United States for over a year. COVID is still out there. Here's what to do if you get it now 2023-03-24T04:00:00Z Abundant research demonstrates that vaccine effectiveness wanes quickly against the dominant omicron subvariants. Opinion | Vulnerable people should be allowed a second bivalent shot this spring 2023-03-28T04:00:00Z In the past, major gaps in immunity have been followed by major surges, such as with delta and omicron. The COVID virus has mutated so much since 2019 that some experts say it should be renamed SARS-CoV-3 2023-04-13T04:00:00Z An omicron subvariant, XBB.1.5, now accounts for almost 90 percent of the cases in the United States, according to the CDC. FDA to okay second omicron-targeting booster for some, officials say 2023-04-03T04:00:00Z During the spring break travel period last year, airlines still were grappling with staffing shortages while rebounding from the effects of the omicron variant of the coronavirus, which emerged in November 2021. Leaving for spring break? Travelers have plenty of company this year. 2023-03-21T04:00:00Z But with the emergence of the highly infectious omicron variant last year, many of China’s top medical experts and officials worried zero-COVID was unsustainable. Ignoring experts, China’s sudden zero-COVID exit cost lives 2023-03-20T04:00:00Z A CDC study last year found that while the original monovalent booster was 89 percent effective at preventing hospitalization against omicron, this protection dropped to 66 percent after four to five months.

Ignoring experts, China’s sudden zero-COVID exit cost lives 2023-03-20T04:00:00Z In 2021, a significant omicron outbreak was traced to someone who contracted the virus after being confined to a quarantine hotel. Opinion | In Hong Kong, face masks are finally optional — but distrust remains 2023-03-19T04:00:00Z By February 2022, however, as the impact of omicron began to fade, travel demand rebounded. Leaving for spring break? Travelers have plenty of company this year. 2023-03-21T04:00:00Z So the country stuck to mass testing and quarantining millions of people, even as omicron evaded increasingly draconian controls. Ignoring experts, China’s sudden zero-COVID exit cost lives 2023-03-20T04:00:00Z An important study from Britain finds more evidence for the omicron variant being milder than previous variants. Opinion | The Checkup With Dr. Wen: 8 ideas from the surgeon general to address loneliness 2023-03-09T05:00:00Z Dr. Stuart Campbell Ray, an infectious disease expert at Johns Hopkins, said the current omicron variants have about 100 genetic differences from the original coronavirus strain. Pandemic 3 years later: Has the COVID-19 virus won? 2023-03-10T05:00:00Z The bivalent is a combination of the original vaccine plus a component that targets two omicron subvariants.

Japan to ease COVID border measures for travelers from China 2023-02-27T05:00:00Z The less lethal but far more infectious omicron made curbing COVID-19 harder and the risks of its spread lower, and nearby Korea, Japan and Singapore were all loosening controls. Ignoring experts, China’s sudden zero-COVID exit cost lives 2023-03-20T04:00:00Z After the omicron variant emerged, organizers postponed last year’s event and scaled it back, allowing samba schools with their electrifying costumes and floats to parade, but barring the hundreds of roving street parties called blocos. After covid break and Brasília riot, Rio celebrates ‘Carnival of democracy’ 2023-02-21T05:00:00Z Unlike January 2022, when airlines were grappling with the effects of weather and the omicron coronavirus variant, the first quarter of 2023 is starting strong, she said. Reagan National sets passenger record in 2022 as leisure travel jumps 2023-02-18T05:00:00Z The omicron XBB.1.5 variant is the most dominant in the U.S., Catching COVID gives you ‘durable’ protection from virus, but for how long? 2023-02-17T05:00:00Z One estimate, published last year by scientists largely at Fudan University in Shanghai, used a previous omicron outbreak in Shanghai to estimate how quickly the virus might spread in mainland China.

COVID’s omicron variant, thought to be milder, can increase risk for diabetes 2023-02-14T05:00:00Z The updated booster elicits a better antibody response against omicron variants compared with the original. Opinion | Should there be an annual coronavirus booster? It depends. 2023-02-07T05:00:00Z If a person was previously infected with a COVID-19 variant other than omicron, the protection against a subsequent omicron infection was significantly lower, the research noted. Catching COVID gives you ‘durable’ protection from virus, but for how long? 2023-02-17T05:00:00Z Deadly delta and omicron waves scrambled his plans, prompting him to float a series of vaccine rules even as the variants cast doubt on the vaccines’ ability to thwart transmission from person to person. Biden: COVID-19 not gone but no longer has ‘grip’ on America 2023-02-07T05:00:00Z Zhong, the prominent doctor, presented data from Hong Kong showing omicron’s low fatality rate after the city’s last outbreak, two said. Ignoring experts, China’s sudden zero-COVID exit cost lives 2023-03-20T04:00:00Z However, it’s hard to know whether the added benefit of the bivalent booster was because it increased protection against the omicron subvariants or because less time had passed since people got it. Who should get a COVID booster now? New data offers some clarity. 2023-02-07T05:00:00Z Several studies have found that rapid tests performed just as well on the first omicron variant as they did on earlier strains of the virus. Do Rapid Tests Still Work? 2023-01-30T05:00:00Z However, if a person was previously infected with omicron, there was a higher chance of being protected against a future omicron infection — but not for the BA.4 and BA.5 subvariants, researchers wrote. Catching COVID gives you ‘durable’ protection from virus, but for how long? 2023-02-17T05:00:00Z “As we enter the fourth year of the pandemic, there is no doubt we are in a far better situation now than we were a year ago when the omicron wave was at its peak.” WHO says COVID-19 remains an international emergency but is at transition point 2023-01-30T05:00:00Z Researchers evaluated vaccine effectiveness during the time of omicron dominance, and found that protection with the Pfizer vaccine was 58 percent after 15 days, 50 percent after 31 days and 41 percent after 61 days.

FDA advisers favor retiring original covid shot and using newer version 2023-01-26T05:00:00Z “We’re still protected against severe disease, thank goodness,” even after the latest mutated omicron strains cropped up, noted FDA adviser Dr. Paul Offit, a vaccine expert at Children’s Hospital of Philadelphia. FDA’s advisers back plan to simplify COVID-19 vaccinations 2023-01-26T05:00:00Z Some limitations of the study include how fewer studies the authors included had data on the original omicron strain and its sublineages. Catching COVID gives you ‘durable’ protection from virus, but for how long? 2023-02-17T05:00:00Z The most recent booster shots are “bivalent” ones that target both the original strain and descendants of the omicron strain discovered in late 2021. FDA debates simplified, flu-like COVID vaccine campaigns; most people would get one dose 2023-01-26T05:00:00Z But the more concerning variants — think alpha, delta or the many off-shoots of omicron — can spread global illness, disability and death. COVID is spreading from humans to animals and back again 2023-01-24T05:00:00Z Advisers to the Food and Drug Administration on Thursday unanimously endorsed retiring the original coronavirus shot in favor of one that targets both the original strain of the coronavirus and the omicron variant. FDA advisers favor retiring original covid shot and using newer version 2023-01-26T05:00:00Z The updated boosters launched last fall were also tweaked to target omicron relatives that had been dominant. US proposes once-a-year COVID shots for most Americans 2023-01-23T05:00:00Z The omicron surge caused nearly 160,000 people to be hospitalized for the virus at one point. ER visits for COVID, flu, RSV declining, CDC says 2023-01-23T05:00:00Z “As awful as omicron was, it left in its wake a tremendous amount of immunity,” said Jennifer Nuzzo, an epidemiologist at Brown University School of Public Health. Covid, flu, RSV declining in hospitals as ‘tripledemic’ threat fades 2023-01-22T05:00:00Z While there's no guarantee China's outbreak will create huge problems for the rest of the world, we did see omicron and delta emerge from similar waves. COVID is spreading from humans to animals and back again 2023-01-24T05:00:00Z “China had a year to prepare,” he said, noting the end of 2021 when omicron emerged. Why China dumped its ‘zero covid’ policy so suddenly — and disastrously 2023-01-19T05:00:00Z The study identified a protein, nsp6, that plays a role in lessening the lethality of omicron compared with the ancestral strain. Lab-leak fears are putting virologists under scrutiny 2023-01-18T05:00:00Z But at that time, U.S. officials believe, Xi probably knew that the omicron variant had spread so widely that it couldn’t be contained. Opinion | Xi’s course correction reveals an agile autocrat under pressure 2023-01-19T05:00:00Z Public health officials are closely monitoring the spread of XBB.1.5, an omicron subvariant that is the most transmissible form of the coronavirus yet seen. The doctor won’t see you now: Covid winters are making long hospital waits the new normal 2023-01-12T05:00:00Z But as this winter approached, more contagious offshoots of the omicron variant began to spread, despite the harsh restrictions, and rare protests against the restrictions prompted officials to reverse course, lifting almost all of them. Is this China’s full covid data? Why the WHO is pushing for more. 2023-01-16T05:00:00Z Consumer confidence in China last year plunged to an all-time low amid the reimposition of lockdowns during the rise of the coronavirus’s omicron variant. China’s bid to leave covid behind could determine global economy’s fate 2023-01-15T05:00:00Z He noted that it used an early version of omicron, BA.1, and so the recombinant virus would not have been able to compete against later, more transmissible subvariants of omicron. Lab-leak fears are putting virologists under scrutiny 2023-01-18T05:00:00Z China’s abrupt pivot from “zero-COVID” in early December unleashed a surge of omicron infections and led to 59,938 virus-related deaths in the nation’s hospitals through Jan. 12, the National Health Commission disclosed this weekend. China’s hospital COVID death data just a 10th of total toll, experts say 2023-01-16T05:00:00Z It has already become the dominant lineage in the Northeast and will probably, at current rates, take over everywhere, outcompeting other omicron variants. The doctor won’t see you now: Covid winters are making long hospital waits the new normal 2023-01-12T05:00:00Z The numbers appear to show an outbreak similar to the waves of omicron that washed over other countries a year ago. Is this China’s full covid data? Why the WHO is pushing for more. 2023-01-16T05:00:00Z After mass protests against those measures in late November and a surge in omicron cases, authorities suddenly dropped those restrictions on Dec. 7. China sharply revises death toll linked to covid outbreak to 60,000 from 37 2023-01-14T05:00:00Z But it was still much deadlier in these mice than omicron. Lab-leak fears are putting virologists under scrutiny 2023-01-18T05:00:00Z When omicron hit South Korea, daily deaths quickly climbed to nearly seven for every 1 million people. China’s hospital COVID death data just a 10th of total toll, experts say 2023-01-16T05:00:00Z Still, for more than a year, all of the new circulating versions of the virus have been subvariants of omicron and have not shown signs of making people sicker. The doctor won’t see you now: Covid winters are making long hospital waits the new normal 2023-01-12T05:00:00Z But he noted the situation was nothing like it was a year ago, when the then-new omicron variant was causing the largest national surge of COVID-19 hospitalizations since the pandemic began. Holidays didn’t lead to feared bump in flu cases, CDC says 2023-01-13T05:00:00Z Health officials have tried to reassure the public by citing the relatively low fatality rate resulting from infection by the omicron variant. China, engulfed in covid chaos, braces for Lunar New Year case spike 2023-01-11T05:00:00Z This suggested that the spike protein wasn’t the only element of omicron making it less lethal. Lab-leak fears are putting virologists under scrutiny 2023-01-18T05:00:00Z In a lab experiment, the researchers combined the spike protein of an early lineage of omicron with the backbone of the original strain that emerged in Wuhan, China. Coronavirus ‘chimera’ made in lab shows what makes omicron seemingly less deadly 2023-01-11T05:00:00Z The U.S. population had much more immunity from vaccines and previous infections, but the omicron variant was leaps and bounds more transmissible than previous ones. The doctor won’t see you now: Covid winters are making long hospital waits the new normal 2023-01-12T05:00:00Z In late November 2021, when South African scientists flagged omicron as a worrisome new strain, I supported travel restrictions. Opinion | The coronavirus testing requirement for Chinese travelers is misguided 2023-01-09T05:00:00Z New covid variant: XBB.1.5, a new covid variant pegged by the World Health Organization as “the most transmissible” descendant yet of the omicron variant, is quickly becoming the dominant strain in the U.S. China, engulfed in covid chaos, braces for Lunar New Year case spike 2023-01-11T05:00:00Z It is outcompeting a soup of new omicron variants that have arisen in recent months. Opinion | The coronavirus is speaking. It’s saying it’s not done with us. 2023-01-08T05:00:00Z The chimeric virus grew just like omicron in cell cultures. Coronavirus ‘chimera’ made in lab shows what makes omicron seemingly less deadly 2023-01-11T05:00:00Z Since the omicron variant ignited an explosion of cases last winter, it spawned a host of descendants that are even more adept at slipping past antibodies and caused most infections in the United States. New variant XBB.1.5 is ‘most transmissible’ yet, could fuel covid wave 2023-01-08T05:00:00Z At that time, the restrictions were meant to buy us time to vaccinate more elderly people and, crucially, to study omicron, about which little was known. Opinion | The coronavirus testing requirement for Chinese travelers is misguided 2023-01-09T05:00:00Z The evidence is still being collected on the power of vaccines and the bivalent booster, which is formulated with a component aimed at a previous version of omicron. No, vaccines aren’t making new COVID-19 variants worse 2023-01-08T05:00:00Z Hospitalizations have risen among seniors to levels only the first omicron wave surpassed. Opinion | The coronavirus is speaking. It’s saying it’s not done with us. 2023-01-08T05:00:00Z The research showed that omicron’s heavily mutated spike protein plays a role in making the variant less pathogenic than the ancestral strain. Coronavirus ‘chimera’ made in lab shows what makes omicron seemingly less deadly 2023-01-11T05:00:00Z While XBB.1.5’s mutations have sparked scientific intrigue, experts caution it doesn’t substantially change circumstances for ordinary people navigating pandemic life with omicron’s descendants as the dominant strains since last spring. New variant XBB.1.5 is ‘most transmissible’ yet, could fuel covid wave 2023-01-08T05:00:00Z The XBB.1.5 strain is a recombined version of variants that spun off from omicron, the form of the coronavirus that caused havoc last winter. New omicron variant considered ‘most transmissible’ yet blankets Northeast 2023-01-06T05:00:00Z Bhattacharyya pointed to a study he led last year showing that vaccination probably didn’t accelerate the initial omicron wave — omicron spread equally fast in highly vaccinated states as in poorly vaccinated states. No, vaccines aren’t making new COVID-19 variants worse 2023-01-08T05:00:00Z Will we see a whole new family of variants arise that are distinct from the omicron family? Opinion | The coronavirus is speaking. It’s saying it’s not done with us. 2023-01-08T05:00:00Z The delta and omicron variants developed in places that also had large outbreaks, which can be a breeding ground for new variants. EXPLAINER: Is China sharing enough COVID-19 information? 2023-01-05T05:00:00Z It’s already shown it can spot coronavirus variants early — detecting omicron variants BA.2 and BA.3 and reporting them to a global database weeks before others did. As COVID surges in China, US begins testing more travelers 2023-01-05T05:00:00Z A pilot program was expanded around the time the first omicron variant emerged in the U.S. more than a year ago. As COVID surges in China, U.S. begins testing more travelers 2023-01-05T05:00:00Z Two versions of the omicron variant BA.2 must have infected the same person at the same time and swapped genetic material to produce something new. No, vaccines aren’t making new COVID-19 variants worse 2023-01-08T05:00:00Z But the last Greek-named variant, omicron, emerged more than a year ago and left no room for the emergence of other, significantly different strains. What we know about the ‘kraken’ COVID variant XBB.1.5 and why it’s causing concern 2023-01-05T05:00:00Z Khean, noting that South Africa’s early warning about omicron led to bans on travelers from the country, said there is a need to foster an environment where countries can share data without fear of repercussions. EXPLAINER: Is China sharing enough COVID-19 information? 2023-01-05T05:00:00Z Experts believe that a widespread perception that the omicron variant is less severe than previous versions of the coronavirus has led to lowered demand in other nations. Amid low demand, global coronavirus vaccination set to slow in 2023 2023-01-04T05:00:00Z It’s already shown it can spot coronavirus variants early - detecting omicron variants BA.2 and BA.3 and reporting them to a global database weeks before others did. As COVID surges in China, U.S. begins testing more travelers 2023-01-05T05:00:00Z According to a statement from the WHO, sequencing data provided by China shows that cases there are largely offshoots of the omicron variant and that no new variant has been detected. Restrictions on travelers from China mount as covid numbers there surge 2023-01-04T05:00:00Z To summarize, XBB.1.5 is great at evading immunity, but it doesn't seem to cause more severe hospitalizations or death than other omicron strains. Why the new COVID variant XBB.1.5 is taking over the U.S. so quickly 2023-01-04T05:00:00Z They want more people to get bivalent booster shots that attack both the original strain of the virus and the omicron variants that are circulating now. Biden enters the 2024 cycle with firm progress on COVID-19, though hurdles loom 2023-01-03T05:00:00Z It might delay transmission of a new variant, although China is now afflicted mostly with omicron, which is already widespread in the United States and elsewhere. Opinion | China’s covid explosion shows why we need a genomic early warning radar 2022-12-31T05:00:00Z As surveillance continues, scientists believe that the omicron variant BF.7, which is extremely adept at evading immunity, is driving China’s current surge. As COVID surges in China, U.S. begins testing more travelers 2023-01-05T05:00:00Z “It is worrisome given the apparent capacity of this omicron subvariant to evade the immune response generated by past infection and/or vaccination,” he added. ‘Highly contagious’ XBB variant dominant as coronavirus levels rise in Boston wastewater 2022-12-30T05:00:00Z And as we saw in January 2022, if a strain like omicron is contagious enough, even a relatively "mild" version of the virus can spread chaos just through sheer volume of cases. Why the new COVID variant XBB.1.5 is taking over the U.S. so quickly 2023-01-04T05:00:00Z In February, omicron set a new high of over 64,700 new infections. Indonesia lifts all COVID curbs, shifts to endemic approach 2022-12-30T05:00:00Z Its elderly are under-vaccinated, and the population lacks natural immunity to omicron. Opinion | China’s covid explosion shows why we need a genomic early warning radar 2022-12-31T05:00:00Z Health-care experts noted that comparably strict measures did not stop the omicron variant from spreading last winter. Countries rush to control China travel, but covid risks low, experts say 2022-12-29T05:00:00Z The daily average of deaths is now 11, which is lower than the daily death rate during the initial omicron surge. ‘Highly contagious’ XBB variant dominant as coronavirus levels rise in Boston wastewater 2022-12-30T05:00:00Z The new variant is spreading so fast that it rivals the omicron surge in late 2021 and early 2022 in its ability to cause so much illness so fast. Why the new COVID variant XBB.1.5 is taking over the U.S. so quickly 2023-01-04T05:00:00Z “Under the omicron variants, the mandated initial regimen no longer constitutes appropriately sufficient vaccination,” lead researcher Soham Sinha, a member of the University of Chicago’s Department of Public Health Sciences, told The Washington Times. Original COVID vaccines haven’t protected nursing homes in over a year, study finds 2022-12-29T05:00:00Z Fortunately, subsequent sequencing showed they were infected with omicron, not a new variant. Opinion | China’s covid explosion shows why we need a genomic early warning radar 2022-12-31T05:00:00Z The European Commission said Thursday that the BF7 omicron variant prevalent in China was already active in Europe and that its threat has not significantly grown. EU assesses impact China’s rollback of COVID measures 2022-12-29T05:00:00Z The XBB omicron subvariant has now become the dominant strain in New England, according to this week’s variant update from the CDC. ‘Highly contagious’ XBB variant dominant as coronavirus levels rise in Boston wastewater 2022-12-30T05:00:00Z Despite his institute’s high projections, Mokdad said he doesn’t believe new travel restrictions are warranted, particularly given that omicron subvariants are already circulating widely around the world. U.S. to impose new coronavirus testing requirements for travelers from China 2022-12-28T05:00:00Z But a separate study of nursing home residents, published Dec. 7 in the same journal, found infections and hospitalizations dropped in two large systems that required boosters for staff during the delta and omicron waves. Original COVID vaccines haven’t protected nursing homes in over a year, study finds 2022-12-29T05:00:00Z An aggressive new offspring of omicron, XBB.1.5, is taking hold in New York and the Northeast. Opinion | China’s covid explosion shows why we need a genomic early warning radar 2022-12-31T05:00:00Z “What we want to avoid is having a variant enter into the U.S. and spread like we saw with delta or omicron,” said Matthew Binnicker, director of clinical virology at Mayo Clinic in Rochester, Minnesota. U.S. will require COVID-19 testing for travelers from China 2022-12-28T05:00:00Z Children who have already completed that series aren’t yet eligible for the booster that targets omicron. Getting vaccinated this holiday season? Here’s how to stay up-to-date on your COVID shots 2022-12-27T05:00:00Z “A Chinese guy coming with omicron is not going to harm me at all.” U.S. to impose new coronavirus testing requirements for travelers from China 2022-12-28T05:00:00Z Mr. Sinha said 20,000 fewer residents would have died in nursing homes had they all increased average staff vaccination rates by 10 percentage points before omicron. Original COVID vaccines haven’t protected nursing homes in over a year, study finds 2022-12-29T05:00:00Z "We were just coming out of the omicron wave, the winter had been bad. There was no guarantee we were going to have the recover or that it was going to be strong."

Opinion | I’m a doctor. Here’s why my kids won’t wear masks this school year. 2022-08-23T04:00:00Z Dr. William Schaffner, an infectious diseases specialist who teaches at Vanderbilt University Medical Center, said the study also confirms that “general population immunity” has made omicron infections “much less severe.” Medical study finds patients unaware of omicron infections 2022-08-17T04:00:00Z In addition, the omicron subvariants cause less severe disease compared with previous variants. Opinion | The CDC’s updated covid school guidance is ushering in a new normal 2022-08-11T04:00:00Z Last year, the omicron wave caused an enormous amount of disruption.

You could have been spreading the omicron variant without knowing it, study says 2022-08-19T04:00:00Z Vaccination, while less protective against symptomatic disease due to omicron, continues to provide excellent protection against severe illness. Opinion | I’m a doctor. Here’s why my kids won’t wear masks this school year. 2022-08-23T04:00:00Z The revision by the CDC of its coronavirus guidance is the most significant move by the agency since the massive outbreak of infections from omicron last winter. CDC loosens coronavirus guidance, signaling strategic shift 2022-08-11T04:00:00Z Both the Pennsylvania and U.S. figures stop at the end of 2021, when the omicron surge was getting underway. Years into the COVID pandemic, hospital care still may not save you from dying 2022-08-11T04:00:00Z Some have also been moving away from test-to-stay programs that became unmanageable during surges of the omicron variant last school year. CDC drops quarantine, screening recommendations for COVID-19 2022-08-11T04:00:00Z Indeed, from the primordial alpha variant to the delta variant to omicron, new variants emerge when unique mutations make a strain either more contagious, or more capable of evading immunity from previous infections and vaccines. Why BA.5 became the dominant COVID variant 2022-08-10T04:00:00Z It said it plans to release revamped vaccines tailored to the latest omicron variants as early as October, which could lead to a fall booster campaign. BioNTech reports strong first half, expects demand to grow 2022-08-08T04:00:00Z The CDC had been recommending a 10-day isolation period up to that point, but omicron quickly decimated the labor force and the agency abruptly cut isolation guidance in half.

COVID boosters in WA: What to know amid our lackluster rate of follow-up 2022-08-06T04:00:00Z The omicron variants are even more transmissible than delta. Why BA.5 became the dominant COVID variant 2022-08-10T04:00:00Z It said that Lauterbach has had four vaccine shots and his infection “shows that, with the highly contagious omicron variant, an infection can’t be entirely ruled out even with utmost caution.” Germany’s health minister tests positive for COVID-19 2022-08-05T04:00:00Z Although the latest omicron subvariant, BA.5, has fueled a wave of infections in many parts of the country over the past two months, the great majority of those cases have not required hospitalization. CDC loosens coronavirus guidance, signaling strategic shift 2022-08-11T04:00:00Z Indeed, omicron's mutations have a remarkable ability to evade immunity from vaccines, previous infection, or both. How many times can you get reinfected with COVID? Here's what experts say 2022-08-06T04:00:00Z Infection levels were on the decline after an explosion of summer delta cases, and the omicron variant hadn’t yet taken hold in the state. COVID boosters in WA: What to know amid our lackluster rate of follow-up 2022-08-06T04:00:00Z The first version of omicron was estimated to have a R-naught value of 9.5, meaning one infected person would, in an uncontrolled situation, spread it to an average of 9.5 others. Why BA.5 became the dominant COVID variant 2022-08-10T04:00:00Z Germany, like many other countries, has seen large — though recently declining — numbers of cases this summer as new subvariants of omicron drive infections. Germany’s health minister tests positive for COVID-19 2022-08-05T04:00:00Z Vaccines: For people under 50, second booster doses are on hold while the Biden administration works to roll out shots specifically targeting the omicron subvariants this fall. CDC loosens coronavirus guidance, signaling strategic shift 2022-08-11T04:00:00Z "If you got caught delta towards the end of its wave in October you could totally get infected again in January by omicron because omicron is really different from delta," Bhattacharya said. How many times can you get reinfected with COVID? Here's what experts say 2022-08-06T04:00:00Z “Two doses does not cut it with omicron.” COVID boosters in WA: What to know amid our lackluster rate of follow-up 2022-08-06T04:00:00Z "I don't think that it's going to drift so much that a vaccine that contains either of those existing omicron epitopes is going to not work," Tan said.
