The omicron variant is making headlines as the world’s newest strain of coronavirus. In the United States, where nearly 200,000 new coronavirus cases were reported Tuesday by Johns Hopkins University, top public health officials warn Americans to stay vigilant even as vaccination rates rise and travelers from countries where the variant was first detected are shut out. 

Rochelle Walensky, director of the U.S. Centers for Disease Control and Prevention, said during a news briefing on Tuesday that the delta variant accounts for 99% of positive cases sequenced in the United States. She and other members of the White House’s COVID-19 response team asked the public for patience as researchers learn more about the omicron variant, which was first reported in South Africa on November 24.

In the U.S., 19 states have reported omicron infections, but that number is expected to rise as Americans continue to grapple with a pandemic that has persisted since the first COVID-19 case was identified in Washington state in January 2020.

“We must act together, in this moment, to address the impact of the current cases we are seeing, which are largely delta, and to prepare ourselves for the possibility of more omicron,” Walensky said. 

The jury is still out on several key questions related to the variant’s transmissibility, severity and ability to evade immune responses, according to Anthony Fauci, the White House’s chief medical adviser. But early data is encouraging, he said. Preliminary evidence from South Africa, where omicron has overtaken delta as the country’s dominant variant, shows shorter hospital visits and reduced need for ventilators.

“It’s too early to be able to determine the precise severity of disease, but … it appears that with the cases that are seen, we have not seen a very severe profile of disease,” Fauci said. “In fact, it might be – and I underscore, might – be less severe.” 

Still, Fauci said many COVID-19 variants demonstrate increased transmissibility, underscoring the interconnectedness of a pandemic where hot spots often expand to engulf larger shares of the population. Omicron may be more transmissible than the delta variant, according to Fauci.

To help fight this, Jeff Zients, the administration’s COVID-19 coordinator, said the U.S. has donated more than 300 million vaccine doses to 110 countries since Biden opened America’s vaccine reserves in June. These efforts join a new program headed by the U.S. Agency for International Development to expand access and infrastructure in countries where vaccination rates lag. The program, called the Initiative for Global Vaccine Access, pledges $400 million to shore up poorer countries’ vaccine manufacturing and delivery capabilities, especially in sub-Saharan Africa. 

Southern African countries have been the subject of recent travel restrictions after researchers in South Africa first discovered the omicron variant. The Biden administration announced November 26 that travelers from eight African countries would be barred from the United States, and on Monday, the CDC began asking travelers passing through U.S. airports to submit proof of a negative COVID-19 test.

“There are lots of unknowns about the transmissibility, the severity, the vaccine impact of omicron,” Zients said. “We understand that this limitation is causing difficulty for those in southern Africa, but we think a temporary limitation on a limited number of countries until we have the answers we need is a reasonable measure for a reasonable period of time.” 

Zients said the administration continues to make progress in vaccinating Americans: Last week, 12.5 million shots were administered, the highest weekly total since May. On Tuesday, 5 million children ages 5 to 11 received at least one dose – a “major milestone in our effort to keep our kids safe and our schools open,” Zients said.

Nearly 61% of the U.S. population is fully vaccinated against COVID-19, according to Johns Hopkins University data. CDC data show climbing demand for vaccines as the omicron variant spreads and more age groups become eligible for the shot. Nearly 2.2 million vaccines were administered last Thursday, the highest single-day total in seven months. In the past week, nearly 7 million people received a booster, according to Zients.

Though research is still under way on how effective current vaccines are against the omicron variant, Walensky, Fauci and Zients encouraged Americans to stick with tried-and-true methods of limiting the spread of the coronavirus: testing, contact tracing, physical distancing and masks.

“At a time where there is much uncertainty with omicron, we find ourselves in a far better position now than we were last year,” Walensky said. “We have gained knowledge and experience from addressing other variants, such as delta, and we have far more science, tools and treatment options available.”

As South Africa struggles with a new surge of COVID-19 infections due to the omicron variant of the coronavirus, a new study suggests omicron could be less severe than other forms of the virus.

The New York Times reports doctors at the Steve Biko Academic and Tshwane District Hospital Complex in Pretoria observed 42 patients who had been admitted last week with COVID-19.They found that 29 patients were breathing ordinary air, while four of 13 patients who were using supplemental oxygen were doing so for reasons unrelated to the virus.

Dr. Fareed Abdullah, the director of the Office of HIV/AIDS and Tuberculosis Research at the South African Medical Research Council, told the Times that the 166 coronavirus patients who were admitted to the hospital between November 14 and November 29 had an average hospital stay of 2.8 days, with fewer than 7 percent dying.

In comparison, COVID-19 patients at the hospital over the previous 18 months stayed an average of 8.5 days, with 17 percent dying.

The report also says 80 percent of the 166 patients were under 50 years old, a change from earlier waves of COVID-19 patients, who were older. It says that suggests a high vaccination rate in South Africans over age 50.

Dr. Abdullah cautioned that the study has not been peer-reviewed, and it is not known how many patients were diagnosed with the omicron variant.

South Africa’s National Institute for Communicable Diseases says new coronavirus infections have reached more than 16,000, up dramatically from 2,300 cases reported last Monday.

The NICD says the rapid increase in cases is “unprecedented” in the trajectory of the pandemic, now in its fourth phase in South Africa.

Ian Sanne, an infectious disease specialist who serves on South Africa’s COVID-19 presidential advisory committee, is advising hospitals to prepare for “significant surges” of patients in coming weeks and months, and to make sure they have plenty of oxygen.

Meanwhile, the U.S. Centers for Disease Control and Prevention has designated France and other nations as “very high” risk for travelers to contract COVID-19.The other nations on the CDC’s “Level 4” list are Andorra, Cyprus, Jordan, Liechtenstein, Portugal and Tanzania. The nations join 78 other destinations the CDC is urging Americans to either avoid or ensure they are fully vaccinated before traveling.

Rohingya refugees from Myanmar are suing Meta Platforms Inc, formerly known as Facebook, for $150 billion over allegations that the social media company did not take action against anti-Rohingya hate speech that contributed to violence. 

A U.S. class-action complaint, filed in California on Monday by law firms Edelson PC and Fields PLLC, argues that the company’s failures to police content and its platform’s design contributed to real-world violence faced by the Rohingya community. In a coordinated action, British lawyers also submitted a letter of notice to Facebook’s London office. 

Facebook did not immediately respond to a Reuters request for comment about the lawsuit. The company has said it was “too slow to prevent misinformation and hate” in Myanmar and has said it has since taken steps to crack down on platform abuses in the region, including banning the military from Facebook and Instagram after the February 1 coup. 

Facebook has said it is protected from liability over content posted by users by a U.S. internet law known as Section 230, which holds that online platforms are not liable for content posted by third parties. The complaint says it seeks to apply Burmese law to the claims if Section 230 is raised as a defense. 

Although U.S. courts can apply foreign law to cases where the alleged harms and activity by companies took place in other countries, two legal experts interviewed by Reuters said they did not know of a successful precedent for foreign law being invoked in lawsuits against social media companies where Section 230 protections could apply. 

Anupam Chander, a professor at Georgetown University Law Center, said that invoking Burmese law wasn’t “inappropriate.” But he predicted that “It’s unlikely to be successful,” saying that “It would be odd for Congress to have foreclosed actions under U.S. law but permitted them to proceed under foreign law.” 

More than 730,000 Rohingya Muslims fled Myanmar’s Rakhine state in August 2017 after a military crackdown that refugees said included mass killings and rape. Rights groups documented killings of civilians and burning of villages. 

Myanmar authorities say they were battling an insurgency and deny carrying out systematic atrocities. 

In 2018, U.N. human rights investigators said the use of Facebook had played a key role in spreading hate speech that fueled the violence. A Reuters investigation hat year, cited in the U.S. complaint, found more than 1,000 examples of posts, comments and images attacking the Rohingya and other Muslims on Facebook. 

The International Criminal Court has opened a case into the accusations of crimes in the region. In September, a U.S. federal judge ordered Facebook to release records of accounts connected to anti-Rohingya violence in Myanmar that the social media giant had shut down. 

The new class-action lawsuit references claims by Facebook whistleblower Frances Haugen, who leaked a cache  of internal documents this year, that the company does not police abusive content in countries where such speech is likely to cause the most harm. 

The complaint also cites recent media reports, including a Reuters report last month, that Myanmar’s military was using fake social media accounts to engage in what is widely referred to in the military as “information combat.”

More than 5 million people worldwide have had their lives cut short by COVID-19, and the number keeps rising as many countries experience another wave of transmission. 

The best defense against this disease is a vaccine, experts say.   

Since the outbreak was first reported in 2019, the best scientists all over the world have been working on a vaccine to protect against SARS‑CoV‑2, the virus that causes COVID-19. The acronym stands for “severe acute respiratory syndrome coronavirus 2” to distinguish it from the first SARS outbreak in 2003. 

Historically, when scientists make vaccines, they have used a live virus that is so weak it can’t reproduce, or they use a dead virus. When these weakened or inactive viruses are injected into the body, the body recognizes them as intruders, produces antibodies and fights them off.  

Polio vaccines have used both weakened live viruses as well as dead ones with enormous success. The Global Polio Eradication Initiative reports that polio cases were reduced by 99.9% between 1988, when the global effort to eliminate polio was started, and 2021. The U.S. Centers for Disease Control and Prevention reports that without the global polio vaccination program, more than 18 million people who are currently healthy would have been paralyzed by the virus. 

As of December 6, three children in the entire world have contracted the wild polio virus in 2021. 

Three of the vaccines developed against COVID-19 are vector vaccines. A vector is simply a delivery system. In this case, scientists use an adenovirus — a cold virus, for example — to deliver a fragment of the coronavirus. The fragment is a gene from a spike on the crown of the coronavirus. This trains the body to fight off any other similar infections, including COVID-19. 

The spike cannot infect someone with the coronavirus.  

The Oxford-AstraZeneca vaccine uses a chimpanzee virus, not a human one. The Johnson & Johnson and Sputnik V vaccines use human adenoviruses. J&J uses a rare adenovirus. Sputnik V uses the same virus in its first dose. In its second dose, Sputnik V uses a common adenovirus that some people might be immune to. For this reason, many scientists are concerned that Sputnik V may not be an effective vaccine. 

Once injected, the viruses enter the cells and start to produce the spike protein, but not COVID-19. Then, the body mounts an attack.  

Dr. Andrea Cox, a professor with a specialty in immunology at the Johns Hopkins University School of Medicine, says our bodies don’t just mount an immune response to the adenovirus, but they also produce an immune response to the spike protein from the coronavirus. In this way, the body learns to fight off the coronavirus if it sees it again.  

The World Health Organization has authorized use of the AstraZeneca and Johnson & Johnson vaccines but not Sputnik V. The WHO says it needs more data from the Sputnik V trials.  

Cox says the AstraZeneca and Johnson & Johnson vaccines are preferred because they have been given to hundreds of millions of people worldwide. Scientists have more information about their side effects and their immune responses than Sputnik V’s simply because Sputnik has been used far less frequently and there are fewer international studies that have assessed it.  

Another issue with Sputnik V, Cox says, is “that the data are not showing the kinds of efficacy rates that we would like to see in a vaccine.”  

Some scientists expect COVID-19 to be with us for three to four years. But even with the best scientists in the world working on vaccines, they are concerned that as the virus continues to infect unvaccinated people and mutate, at some point, the vaccines we have now won’t be able to offer full protection against COVID-19.

Three 2021 Nobel Prize laureates said Monday that climate change is the biggest threat facing the world — yet they remain optimistic — as this year’s winners began receiving their awards at scaled-down local ceremonies adapted for pandemic times. 

For a second year, COVID-19 has scuttled the traditional formal banquet in Stockholm attended by winners of the prizes in chemistry, physics, medicine, literature and economics, which were announced in October. The Nobel Peace Prize is awarded separately in Oslo, Norway. 

Literature laureate Abdulrazak Gurnah was first to get his prize in a lunchtime ceremony Monday at the Swedish ambassador’s grand Georgian residence in central London.

Ambassador Mikaela Kumlin Granit said the U.K.-based Tanzanian author had been awarded the Nobel Prize in literature for his “uncompromising and compassionate penetration of the effects of colonialism and the fate of the refugee in the gulf between cultures and continents.” 

“Customarily you would receive the prize from the hands of His Majesty, the king of Sweden,” she told Gurnah at the ceremony attended by friends, family and colleagues. “However, this year you will be celebrated with a distance forced upon us because of the pandemic.” 

Gurnah, who grew up on the island of Zanzibar and arrived in England as an 18-year-old refugee in the 1960s, has drawn on his experiences for 10 novels, including “Memory of Departure,” “Pilgrims Way,” “Afterlives” and “Paradise.” He has said migration is “not just my story — it’s a phenomenon of our times.” 

Italian physics laureate Giorgio Parisi was receiving his prize at a ceremony in Rome. U.S.-based physics laureate Syukuro Manabe, chemistry laureate David W.C. MacMillan and economic sciences laureate Joshua D. Angrist will be given their medals and diplomas in Washington. 

MacMillan, German physics prize winner Klaus Hasselmann and economics prize winner Guido Imbens, who is Dutch but lives in the United States, had a joint virtual news conference Monday where they were asked what they consider the biggest problem facing humanity and what they worry about most. All three answered climate change, with Imbens calling it the world’s “overarching problem.” 

“Climate change is something which is clearly going to have a large impact on society,” MacMillan said. “But at the same time given the science, given the call to arms amongst scientists, I really feel more optimism. And I feel there’s a real moment happening with scientists moving towards trying to solve this problem.” 

“I would bet on that fact that we would solve this problem,” MacMillan said. 

Hasselmann, whose work on climate change won him the prize, said he’s more hopeful because the world’s youth and movements like Fridays for the Future “have picked up the challenge and are getting across the message to the public that we have to act and respond to the problem.”

Hasselmann said he’s more optimistic now about climate change than 20 or 30 years ago. 

Imbens said he also is disturbed that misinformation, especially about COVID-19 and vaccines, is splitting society apart. He recalled growing up in the Netherlands and nearly everyone agreed on the need for the polio vaccine. 

“And yet, here we don’t seem to have found a way of making these decisions that we can all live with,” Imbens said. “And that’s clearly made it much harder to deal with the pandemic.” 

More ceremonies will be held throughout the week in Germany and the United States. On Friday — the anniversary of the death of prize founder Albert Nobel — there will be a celebratory ceremony at Stockholm City Hall for a local audience, including King Carl XVI Gustav and senior Swedish royals. 

A Nobel Prize comes with a diploma, a gold medal and a $1.5 million (10-million krona) cash award, which is shared if there are multiple winners. 

The Nobel Peace Prize is awarded in Oslo because Nobel wanted it that way, for reasons he kept to himself. A ceremony is due to be held there Friday for the winners — journalists Maria Ressa of the Philippines and Dmitry Muratov of Russia. 

The Norwegian news agency NTB said the festivities would be scaled down, with fewer guests and participants required to wear face masks. Norway has seen an uptick in cases of the new omicron variant, and a spokesman for the Norwegian Nobel Committee told NTB it was “in constant contact with the health authorities in Oslo.”
