Covid-19 Live Updates: Japan, Spain and France Find Cases of the New Virus Variant, Most Linked to U.K. Travel

Japan, Spain and France have found small numbers of infections involving a new, potentially more transmissible variant of the coronavirus, most linked to travel from the U.K., where it was first detected.

The rapid spread of the variant led to the lockdown of London and southern England this week, prompted a temporary French blockade of the English Channel and resulted in countries around the world barring travelers from the U.K. Because few countries have the level of genomic surveillance that Britain does, there is concern that the variant may have been traveling across the world undetected for weeks.

A recent study by British scientists found no evidence that the variant is more deadly than others but estimated that it is 56 percent more contagious.

So far, the British variant has been diagnosed in seven people in Japan, the country’s health ministry said. All had either recently traveled to the U.K. or been in contact with someone who had.

The discovery in Japan prompted the country to close its borders to all new entry by nonresident foreigners. The ban will go into effect at midnight on Monday and last through the end of January, the public broadcaster NHK reported.

In Spain, the variant was found in the capital region, local authorities said on Saturday. Antonio Zapatero, a regional health official, said that four cases had been confirmed in Madrid, while another three were being treated as suspicious. At least two of the cases involve people who had recently been to Britain and then tested positive in Madrid, as well as some of their relatives.

The first case of the new fast-spreading variant of the coronavirus was identified in France on Friday, according to the French health ministry. Officials said that the patient was a French citizen living in Britain who had traveled from London to Tours, a city in central France, on Dec. 19, a day before the British government imposed a lockdown following the emergence of the variant.

It is normal for viruses to mutate, and most of the mutations of the coronavirus have proved minor. The British variant has a constellation of 23 mutations, several of which might alter its transmissibility. Vaccine experts are confident that the available vaccines will be able to block the new variant, although that has to be confirmed by laboratory experiments that are now underway.

The European Union’s member nations are scheduled to begin vaccinating against the virus on Sunday with the Pfizer-BioNTech vaccine. Hungary began administering the vaccine a day early, on Saturday.

A few other concerning variants have also been identified, including one in South Africa and another in Nigeria. The U.K. said on Thursday that it would ban travel from South Africa after the British health secretary, Matt Hancock, said two people were confirmed to have been infected with the variant that emerged there.

Germany and Singapore have identified infections with the new variant. And Denmark, which has wider genomic surveillance than many other countries, detected 33 cases of the variant from Nov. 14 to Dec. 14, according to the Danish health authorities.

The U.S. has not yet reported any cases of the U.K. variant. But the country will require all airline passengers arriving from Britain to test negative for the coronavirus within 72 hours of their departure, the Centers for Disease Control and Prevention said Thursday. The rule will take effect on Monday.

3 European Countries Begin Coronavirus Vaccinations Early

Germany, Hungary and Slovakia began administering the Pfizer-BioNTech coronavirus vaccine on Saturday, one day ahead of the European Union’s official rollout.

A 101-year-old woman in a nursing home in eastern Germany became the country’s first recipient of the BioNTech-Pfizer vaccine on Saturday, a day ahead of the European Union’s planned immunization campaign, an ambitious effort to eventually inoculate more than 450 million people across the 27 nations in the European Union against the coronavirus.

Vaccinations also began in Hungary, where photographs showed health care workers getting the shot at the Southern Pest Central Hospital in Budapest. The authorities in Slovakia also began administering their first doses on Saturday, Reuters reported.

Ursula von der Leyen, the president of the European Union’s executive arm, released a video in advance of the official rollout on Sunday, calling the campaign “a touching moment of unity.”

Roughly two-thirds of all Germans are willing to be vaccinated against coronavirus, according to a survey conducted by YouGov for the German news agency D.P.A., but more than half of respondents said they were concerned about possible side effects.

The doses for Europe are being produced at BioNTech’s manufacturing sites in Germany, and Pfizer’s site in Puurs, Belgium, according to the two companies, and countries across the bloc have begun receiving their first deliveries.

In Germany, all 16 states received 9,750 doses of the vaccine on Saturday. Each state is to send them to regional immunization centers, and then teams of drivers are to distribute them to nursing homes and care centers for the elderly across the country.

Karsten Fischer, who is responsible for managing the response to the pandemic in the Harz district of Saxony-Anhalt, said the logistics in his region made it possible to begin vaccinations within hours of receiving the doses, and he saw no reason to wait.

“We did not want to waste a day, as the stability of the vaccine decreases over time,” Mr. Fischer told the public broadcaster M.D.R. “We wanted to begin administering immediately.”

The first inoculation was administered in the city of Halberstadt, to 101-year-old Edith Kwoizalla; 40 other residents and 11 members of the staff at the nursing home also received doses, M.D.R. reported.

“Every day we wait is one day too many,” Tobias Krüger, the director of the home, told reporters.

Germany’s eastern states have been hardest hit by the second wave of the virus. More than 1.6 million people have been infected in the country, and more than 29,400 have died, many of them older citizens, especially those living in nursing homes.

Residents of nursing homes and their caregivers, as well as emergency medical staff and individuals 80 years and older, are set to be among the first vaccinated in Germany, based on a plan that was drawn up by leaders, medical advisers and members of the national Ethics Council. Members of the government do not plan to receive inoculations before their peers, Jens Spahn, the country’s health minister, said on Saturday.

“We have deliberately said that we will begin offering the vaccine to the most fragile,” Mr. Spahn said. “If there comes a time when it makes sense, say to bolster confidence, each one of us is ready to be vaccinated.”

With bubble-enclosed Santas and Zoom-enhanced family gatherings, much of the United States played it safe over Christmas while the coronavirus rampaged across the country. But, as during Thanksgiving, a significant number of Americans traveled, raising the prospect of a spike in infections on top of the current surge.

Many European countries are under restrictions, but Christmas is celebrated so broadly — and New Year’s festivities will follow shortly — that the concern of a post-holiday spike reaches far beyond a single country.

Case numbers remain about as high as they have ever been, both in the U.S. and throughout the world. Total U.S. infections are about to reach 19 million, while the world total surpassed 80 million on Saturday afternoon, according to a New York Times database.

For now, the U.S. is no longer seeing overall explosive growth, although California’s worsening outbreak has canceled out progress in other parts of the country. The state has added more than 300,000 cases in the seven-day period ending Dec. 22. And six Southern states have seen sustained case increases in the last week: Tennessee, Alabama, Georgia, South Carolina, Florida and Texas.

The country’s virus-related deaths in general have continued to climb. And hospitalizations are hovering at a pandemic height of about 120,000, according to the Covid Tracking Project.

More than 330,000 people in the United States have died since the pandemic began, and two of the four worst days for deaths so far have been during the past week. A number of states set death records on Dec. 22 or Dec. 23, including Alabama, Wisconsin, Arizona and West Virginia, according to The Times’s data.

Holiday reporting anomalies may obscure any post-Christmas spike until the second week of January. Testing was expected to decrease around Christmas, and many states have said they would not report data on certain days. For Dec. 25, numbers for both new infections, 91,922, and deaths, 1,129, were significantly lower than the seven-day averages.

The lessons learned from Thanksgiving are mixed. Case numbers and deaths have continued to rise since, but the patterns look more like a plethora of microspreads than a mass superspreader event.

Over all, experts have told The Times, areas of the U.S. that were improving pre-Thanksgiving — like the Midwest — continued to do well afterward, while regions that were seeing higher numbers before the holiday continued to worsen.

Only time will tell whether new infections will result from increased exposure during the late-December holidays — from seeing family, passing through airports or buying food for celebrations. More than one million people passed through Transportation Safety Administration travel checkpoints on each of four recent days — Dec. 18, 19, 20 and 23 — but that was less than half the number for those days last year, according to the agency’s data. Only a quarter of the number who flew on the day after Christmas last year did so on Friday, and Christmas Eve travel was down by one-third from 2019.

So, as with Thanksgiving, Christmas will produce “a continuing ramification” of whoever is infected over the winter holidays, said Catherine L. Troisi, an infectious-disease epidemiologist at the University of Texas’ School of Public Health in Houston, so it is crucial to keep up protective measures.

What the Ghost of Christmas Yet to Come will bring, Dr. Troisi said, “is up to us.”

Ever since the race to develop a coronavirus vaccine began last spring, upbeat announcements were stalked by ominous polls: No matter how encouraging the news, growing numbers of people said they would refuse to get the shot.

The time frame was dangerously accelerated, many people warned. The vaccine was a scam from Big Pharma, others said. A political ploy by the Trump administration, many Democrats charged. The internet pulsed with apocalyptic predictions from longtime vaccine opponents, who decried the new shot as the epitome of every concern they’d ever put forth.

But over the past few weeks, as the vaccine went from a hypothetical to a reality, something happened. Fresh surveys show attitudes shifting and a clear majority of Americans now eager to get vaccinated.

In polls by Gallup, the Kaiser Family Foundation and the Pew Research Center, the portion of people saying they are now likely or certain to take the vaccine has grown from about 50 percent this summer to more than 60 percent, and in one poll 73 percent — a figure that approaches what some public health experts say would be sufficient for herd immunity.

Resistance to the vaccine is certainly not vanishing. Misinformation and dire warnings are gathering force across social media. At a meeting on December 20, members of an advisory panel to the Centers for Disease Control and Prevention cited strong indications that vaccine denouncements as well as acceptance are growing, so they could not predict whether the public would gobble up limited supplies or take a pass.

But the attitude improvement is striking. A similar shift on another heated pandemic issue was reflected in a different Kaiser poll this month. It found that nearly 75 percent of Americans are now wearing masks when they leave their homes.

The change reflects a constellation of recent events: the uncoupling of the vaccine from Election Day; clinical trial results showing about 95 percent efficacy and relatively modest side effects for the vaccines made by Pfizer-BioNTech and Moderna; and the alarming surge in new coronavirus infections and deaths.

Shortly after 2 p.m. on Dec. 15, Dr. Taison Bell became the second person in his hospital, UVA Health in Charlottesville, to receive a dose of Pfizer’s new coronavirus vaccine. “I feel fine,” he said. “But my right arm, if you were to interview it, is probably not excited about what’s happened to it.”

His limb experienced a bit of swelling and soreness, nothing out of the ordinary for a vaccine. It was a sign that the injection was doing its job: instructing Dr. Bell’s cells to churn out a protein called spike, which will teach his immune system to recognize and thwart the new coronavirus, should he ever encounter it. His second dose, scheduled for early January, will clinch the process.

The shot introduced a microscopic shift that will have an outsize impact on his risk of getting Covid-19. But, Dr. Bell said, little else in his life will change until more of his community joins the vaccinated pool.

Dr. Bell, 37, remains a relative rarity among the people he sees both inside and outside of work. His wife, Kristen, and their children, Alain and Ruby, are unlikely to be vaccinated before the spring or summer. They, like many others, will soon live in a home divided by the splinter-thin prick of a needle — one person vaccinated, three not. They represent a liminal state that will persist for months nationwide, as the first people to be injected navigate a new coexistence with the vulnerable at home.

Although the new vaccines have been shown to be highly effective at preventing people from developing symptomatic cases of Covid-19, little data exists on how well they can stop the spread of the virus, raising the possibility that vaccinated people, despite being much safer individually, could still pose a threat to those they love.

For that reason, “we’re still going to be taking all the same precautions,” Ms. Bell said. “Our day-to-day isn’t going to change for months, as the vaccines continue to get rolled out.

A huge truck jam at the Port of Dover in England eased further on Saturday, days after France lifted a border blockade imposed over fears of a fast-spreading variant of the coronavirus.

As many as 6,000 trucks had lined up at the height of the days-long jam, and many drivers spent a bleak Christmas sleeping in their vehicles as France demanded that all those crossing the border show proof of a negative coronavirus test.

“It was shocking to see that in a G7 country like the U.K., that such things would happen,” said Benjamin Richtzenhain, a traveler who crossed the English Channel on Thursday. He said that the authorities had communicated poorly to those in the logjam and that access to water, bathrooms and blankets had been limited.

The misery at the port added to a general sense of gloom permeating the holiday season in the country. Christmas came scarcely a week after the government announced the presence of a fast-spreading coronavirus variant sweeping the country and imposed widespread lockdowns and other tight restrictions.

By Saturday morning, officials from the transportation department said that about 1,600 vehicles remained in the traffic jam while at least 8,000 had crossed the English Channel via the Eurotunnel since Wednesday, when the authorities ramped up coronavirus testing.

At the port, officials worked intensively on Saturday to test the remaining drivers in hopes of clearing the backup. More than 15,526 have been tested, with 36 coming up positive, the department said.

Hundreds more military personnel were deployed on Friday to reinforce testing efforts and to distribute food and water provided by an array of organizations.

But almost a week after the blockages of sea, rail and air routes, the magnitude of the task made it impossible to predict when the delays would clear and whether drivers would spend yet another day in limbo and another night sleeping in their trucks.

Austria entered a third lockdown on Saturday, with all nonessential shops and schools to remain closed for three weeks and movement to be restricted, after the country eased restrictions in mid-December to allow for preparations ahead of the Christmas holiday.

Until Jan. 24, people in Austria are only allowed to leave their homes for work, shopping or to exercise outdoors, and personal contacts are limited to no more than two households.

“This is our chance to avoid a third wave, or at least do everything we can so that it does not hit us as hard, as it would have without this effort,” Chancellor Sebastian Kurz told public broadcaster ORF in an interview on Saturday.

Ice skating rinks and ski lifts in the alpine country will remain open despite the lockdown, but operating at half capacity and with distancing requirements. Nevertheless, the ski area closest to Vienna saw crowding on Friday that led to authorities closing off some sledding runs and setting up more barriers in the areas around the lifts to better enforce distancing rules.

Some ski areas are requiring people to register when they purchase a lift ticket, as a means of controlling the number of people using the lifts and preventing overcrowding.

In one video, during the lockdown in Wuhan, she filmed a hospital hallway lined with rolling beds, the patients hooked up to blue oxygen tanks. In another, she panned over a community health center, noting that a man said he was charged for a coronavirus test, even though residents believed the tests would be free.

At the time, Zhang Zhan, a 37-year-old former lawyer turned citizen journalist, embodied the Chinese people’s hunger for unfiltered information about the epidemic. She was one of several journalists, professionals and amateurs, who had flocked to Wuhan after the lockdown was imposed in late January.

The authorities were preoccupied with trying to manage the chaos of the outbreak, and for a brief period, China’s strict censorship regime loosened. Reporters seized that window to share residents’ raw accounts of terror and fury.

Now, Ms. Zhang has become a symbol of the government’s efforts to deny its early failings in the crisis and promote a victorious narrative instead.

Ms. Zhang abruptly stopped posting videos in May, after several months of dispatches. The police later revealed that she had been arrested, accused of spreading lies. On Monday, she will go to court, in the first known trial of a chronicler of China’s coronavirus crisis.

The prosecution is part of the Chinese Communist Party’s continuing campaign to recast China’s handling of the outbreak as a succession of wise, triumphant moves by the government. Critics who have pointed to officials’ early missteps have been arrested, censored or threatened by police; three other citizen journalists disappeared from Wuhan before Ms. Zhang did, though none of the rest has been publicly charged.

Prosecutors have accused Ms. Zhang of “picking quarrels and provoking trouble” — a frequent charge for government critics in China — and recommended between four and five years in prison.

Ms. Zhang appeared to know the risks of her actions. In one of her first videos, on Feb. 7, she mentioned that another citizen journalist, Chen Qiushi, had just disappeared, and another, Fang Bin, was under surveillance. Whistleblower doctors had been silenced, she added.

“But as someone who cares about the truth in this country, we have to say that if we just wallow in our sadness and don’t do something to change this reality, then our emotions are cheap,” she said.

Soon after her arrest, she began a hunger strike, according to her lawyers. She has become gaunt and drained but has refused to eat, the lawyers said, maintaining that her strike is her form of protest against her unjust detention.

PORT ELIZABETH, South Africa — When the pandemic began, global public health officials raised grave concerns about the vulnerabilities of Africa. But its countries over all appeared to fare far better than those in Europe or the Americas, upending scientists’ expectations.

Now, the coronavirus is on the rise again in swaths of the continent, posing a new, possibly deadlier threat.

In South Africa, a crush of new cases that spread from Port Elizabeth is growing exponentially across the nation. Eight countries, including Nigeria, Uganda and Mali, recently recorded their highest daily case counts all year.

“The second wave is here,” John N. Nkengasong, the head of the Africa Centers for Disease Control and Prevention, has declared.

When the virus was first detected, many African countries were considered particularly at risk because they had weak medical, laboratory and disease-surveillance systems and were already battling other contagions. Some were riven by armed conflict, limiting health workers’ access. In March, Tedros Adhanom Ghebreyesus, the first African director-general of the World Health Organization, cautioned, “We have to prepare for the worst.”

But many African governments pursued swift, severe lockdowns that — while financially ruinous, especially for their poorest citizens — slowed the rate of infection. Some deployed networks of community health workers. The Africa C.D.C., the W.H.O. and other agencies helped expand testing and moved in protective gear, medical equipment and pharmaceuticals.

The reported toll of the pandemic on the continent — 2.6 million cases and 61,000 deaths, according to the Africa C.D.C. — is lower than what the United States alone currently experiences in three weeks.

But that accounting is almost certainly incomplete. Evidence is growing that many cases were missed, according to an analysis of new studies, visits to nearly a dozen medical institutions and interviews with more than 100 public health officials, scientists, government leaders and medical providers on the continent.

Now, as they battle new outbreaks, doctors are convinced that deaths have also gone uncounted. Dr. John Black, the only infectious-disease specialist for adults in Port Elizabeth, said he and other physicians feared that many people were dying at home. Indeed, a government analysis showed that there had been more than twice as many excess deaths as could be explained by confirmed cases in South Africa. “We don’t know what the real number is,” he said.

Scientists are also considering other explanations for the continent’s outcome. These range from the asymptomatic or mild infections more common in youth — the median age in Africa is just 19.7, about half that of the United States — to unproven factors including pre-existing immunity, patterns of mobility and climate. If those conditions helped protect against the virus earlier, officials ask, will they do so now?

In South Africa, the continent’s leader by far in coronavirus cases and deaths, the growing devastation in its medical system has led to the rationing of care for older adults. Last week, officials announced that a new variant of the virus that may be associated with faster transmission has become dominant. With stricter control measures lifted and many people no longer seeing the virus as a threat, public health officials fear that Africa’s second wave could be far worse than its first.

Then & Now

As 2020 comes to a close, we are revisiting subjects whose lives were affected by the pandemic. When Campbell Robertson first spoke with Yanti Turang in March, she was working in a makeshift Covid-19 tent and treating patients with a novel coronavirus.

In the harrowing days of late March, Yanti Turang was a New Orleans emergency nurse with an ominously relevant résumé: Five years earlier, she had been working on the front lines of the Ebola epidemic in Sierra Leone. What had been a curious background just a few weeks earlier was now expertise in demand.

A few days later, she was working in a Covid-19 tent when she got a call from a physician colleague. “She was like, ‘Can you help me build this hospital?” Ms. Turang recalled. “I said, ‘I don’t really know what you’re talking about.’”

This is how Ms. Turang became the deputy medical operations manager for the enormous field hospital set up by the National Guard in the New Orleans convention center. She would work there for the next eight months.

Though the census of patients at the convention center waxed and waned, it was a huge undertaking. Within her first week, Ms. Turang and her small team discovered that the field hospital was in many ways set up in preparation for a different kind of patient population than it would likely be getting. With the pandemic still new, she said, it was only just becoming clear how destructive it would be for people in nursing homes.

The convention center was set up to take in a typical mix of patients in hospital intensive care units — people who could feed themselves, could walk when they felt better and could turn over in bed on their own — so Ms. Turang and her team began hurriedly transforming it into a hospital designed to care for patients who are elderly, with all the chronic complications that go along with that.

“That’s the huge pivot that we made,” she said. “That’s how we took care of Louisiana.”

All of this work (she also took on a job as a medical consultant to a group of schools in the city) devoured her year. But this month, Ms. Turang was vaccinated, the first concrete signal that an end to the pandemic could be coming.

And after her shot, she did something that she had not allowed herself to do much over the last 10 exhausting, demanding, grief-filled months: She cried.

Since the start of the pandemic, millions of Americans have lost their jobs and tens of thousands of businesses have closed. But the losses in the performing arts and related sectors have been staggering.

During the quarter ending in September, when the overall unemployment rate averaged 8.5 percent, 52 percent of actors, 55 percent of dancers and 27 percent of musicians were out of work, according to the National Endowment for the Arts. By comparison, the jobless rate was 27 percent for waiters; 19 percent for cooks; and about 13 percent for retail salespeople over the same period.

In many areas, arts venues — theaters, clubs, performance spaces, concert halls, festivals — were the first businesses to close, and they are likely to be among the last to reopen.

The public may think of performers as A-list celebrities, but most never get near a red carpet or an awards show. The overwhelming majority, even in the best times, don’t benefit from Hollywood-size paychecks or institutional backing. They work season to season, weekend to weekend or day to day, moving from one gig to the next.

Jennifer Koh, a classical violinist with a dazzling technique, has ridden a career that any aspiring Juilliard grad would dream about — appearing with leading orchestras, recording new works, and performing on some of the world’s most prestigious stages.

Now, nine months into a contagion that has halted most public gatherings and decimated the performing arts, Ms. Koh, who watched a year’s worth of bookings evaporate, is playing music from her living room and receiving food stamps.

“My fear is we’re not just losing jobs, we’re losing careers,” said Adam Krauthamer, president of Local 802 of the American Federation of Musicians in New York. He said 95 percent of the local’s 7,000 members were not working on a regular basis because of the mandated shutdown. “It will create a great cultural depression,” he added.

At the marine terminal in South Brooklyn this month, a sign that said “funeral director” pointed to the left of a vast warehouse just past the guard gate. A row of 53-foot refrigerated trailers, about 20 in all, sat in the black-tarred parking lot.

New York City officials believe this little-known site will help them avoid a repeat of one of the most shocking tragedies of Covid-19’s first wave: the crush of bodies that overwhelmed the city’s capacity for dealing with the dead.

The city experienced a harrowing wave of fatalities as it became the global epicenter of the virus in the spring, with 17,507 confirmed virus deaths between March 14 and June 18. At the peak of the pandemic in early April, about 800 people died in a single day.

More than 135 refrigerated trailers were deployed to the streets around hospitals, in what became one of the most enduring images of the city’s crisis.

As of Dec. 4, the city’s facility at the marine terminal still held 529 bodies in long-term storage and 40 in refrigerated trailers — most of which had been there frozen for months. There is room for hundreds more. (The Wall Street Journal first reported that bodies were still being held at the facility.)

The city has not set a time limit on how long a body can remain there, as long as there are discussions underway with the family for a final resting place. The service is free, said Dr. Barbara Sampson, the city’s chief medical examiner.

How to find somewhere safe to store hundreds of bodies for long stretches was one of the hardest and most traumatic lessons in the first wave of the crisis, one that hospitals, funeral directors and the city medical examiner’s office are reviewing as the second wave of Covid-19 grows in New York.

During the first wave, shelves were placed inside the trailers at hospitals to double their storage capacity. But they were unstable and some collapsed when the trailers were moved. So the city sent strike teams of National Guard and medical examiner staff to hospitals to collect more than 2,000 bodies and bring them to the pier.

This time, the medical examiner has told hospitals not to install shelves, so trailers can be towed full to the pier.

Resilience

Much as the pandemic has been a story of devastation and loss, it has also been one of resilience — of individual people, families and entire communities not only surviving a deadly threat but seeing in the moment a chance to serve others. We asked our correspondents around the world to share stories from this year that speak to the strength of the human spirit, and to how disruption can bring out the best in us.

The teacher had inherited $300,000 and was planning to buy a new car.

But when the virus came, and with it remote learning, he made a U-turn, instead deciding to buy 343 tablets for elementary school students shut out of class because their families could not afford the equipment.

For good measure, the teacher, Hoseein Asadi, also bought the children 30,000 masks to protect them from infection.

Some of his friends and family members thought he had lost his mind.

But Mr. Asadi, 50, has dedicated 28 years to educating elementary school children from villages and nomadic tribes around Khuzestan Province. A father of five who lives in Andimeshk, he said his conscience would not allow him to buy a car when hundreds of students were at the risk of losing an academic year.

“They told me, ‘You will never be able to buy a new car or house on a teacher’s salary,’” Mr. Asadi said in a telephone interview. “But for me seeing the sweet smile on the children’s faces and knowing I had given them the gift of education is enough.”

Overnight, Mr. Asadi became a national hero, appearing on state television and written about in local media outlets. The minister of education telephoned him to personally express his gratitude.

He has also inspired others to act.

State-owned industries, the private sector and ordinary Iranians have mobilized to raise money for tablets. Iranians in the diaspora as far away as Australia have also offered to help. So far, Mr. Asadi said, the education department has received and distributed 12,000 tablets to low-income school districts in several provinces.

“Creating happiness for kids who have nothing is the most rewarding feeling,” Mr. Asadi said.

The end of the pandemic is finally in view. So is rescue from the most traumatic global economic catastrophe since the Great Depression. As coronavirus vaccines enter the bloodstream, recovery has become reality.

But the benefits will be far from equally apportioned.

Wealthy nations in Europe and North America have secured the bulk of limited stocks of vaccines, positioning themselves for starkly improved economic fortunes. Developing countries — home to most of humanity — are left to secure their own doses.

The lopsided distribution of vaccines appears certain to worsen a defining economic reality: The world that emerges from this terrifying chapter in history will be more unequal than ever. Poor countries will continue to be ravaged by the pandemic, forcing them to expend meager resources that are already stretched by growing debts to lenders in the United States, Europe and China.

The global economy has long been cleaved by profound disparities in wealth, education and access to vital elements like clean water, electricity and the internet. The pandemic has trained its death and destruction of livelihood on ethnic minorities, women and lower-income households. The ending is likely to add another division that could shape economic life for years, separating countries with access to vaccines from those without.

“It’s clear that developing countries, and especially poorer developing countries, are going to be excluded for some time,” said Richard Kozul-Wright, director of the division of globalization and development strategies at the United Nations Conference on Trade and Development in Geneva. “Despite the understanding that vaccines need to be seen as a global good, the provision remains largely under control of large pharmaceutical companies in the advanced economies.”

International aid organizations, philanthropists and wealthy nations have coalesced around a promise to ensure that all countries gain the tools needed to fight the pandemic, like protective gear for medical teams as well as tests, therapeutics and vaccines. But they have failed to back their assurances with enough money.

The leading initiative, the Act-Accelerator Partnership — an undertaking of the World Health Organization and the Bill and Melinda Gates Foundation among others — has secured less than $5 billion of a targeted $38 billion.

The United States has secured claims on as many as 1.5 billion doses of vaccine, while the European Union has locked up nearly two billion doses — enough to vaccinate all of their citizens and then some. Many poor countries could be left waiting until 2024 to fully vaccinate their populations.

India is home to pharmaceutical manufacturers that are producing vaccines for multinational companies including AstraZeneca, but its population is unlikely to be fully vaccinated before 2024, according to TS Lombard, an investment research firm in London. Its economy is likely to remain vulnerable.

“You need to vaccinate health care workers globally so you can reopen global markets,” said Clare Wenham, a health policy expert at the London School of Economics. “If every country in the world can say, ‘We know all our vulnerable people are vaccinated,’ then we can return to the global capitalist trading system much quicker.”

Expanded unemployment benefits were set to lapse for millions of struggling Americans on Saturday, a day after President Trump expressed more criticism of a $900 billion pandemic relief bill that was awaiting his signature and would extend them.

The sprawling economic relief package that Congress passed with overwhelming bipartisan support would extend the amount of time that people can collect unemployment benefits until March and revive supplemental unemployment benefits for millions of Americans at $300 a week on top of the usual state benefit.

If Mr. Trump signs the bill on Saturday, states will still need time to reprogram their computer systems to account for the new law, according to Michele Evermore of the National Employment Law Project, but unemployed workers would still be able to claim the benefits.

Further delays could prove more costly. States cannot pay out benefits for weeks that begin before the bill is signed, meaning that if the president does not sign the bill by Saturday, benefits will not restart until the first week of January. But they will still end in mid-March, effectively trimming the extension to 10 weeks from 11.

Mr. Trump blindsided lawmakers on Tuesday when he hinted he may veto the measure, which he decided at the last minute was unsatisfactory. The most pressing issue prompted by the president’s delay was the fate of unemployment benefits. At least a temporary lapse in those benefits is now inevitable.

The country is also facing a looming government shutdown on Tuesday and the expiration of a moratorium on evictions at the end of the year because of the president’s refusal to sign the bill.
