Scientists in China believe new drug can stop coronavirus pandemic 'without vaccine'

May 19: A Chinese laboratory has been developing a drug it believes has the power to bring the coronavirus pandemic to a halt.

The outbreak first emerged in China late last year before spreading across the world, prompting an international race to find treatments and vaccines.

A drug being tested by scientists at China's prestigious Peking University could not only shorten the recovery time for those infected, but even offer short-term immunity from the virus, researchers say.

Sunney Xie, director of the university's Beijing Advanced Innovation Center for Genomics, told AFP that the drug has been successful at the animal testing stage.

"When we injected neutralising antibodies into infected mice, after five days the viral load was reduced by a factor of 2,500," said Xie.

"That means this potential drug has (a) therapeutic effect."

The drug uses neutralising antibodies -- produced by the human immune system to prevent the virus infecting cells -- which Xie's team isolated from the blood of 60 recovered patients.

A study on the team's research, published Sunday in the scientific journal Cell, suggests that using the antibodies provides a potential "cure" for the disease and shortens recovery time.

Xie said his team had been working "day and night" searching for the antibody.

"Our expertise is single-cell genomics rather than immunology or virology. When we realised that the single-cell genomic approach can effectively find the neutralising antibody we were thrilled."

He added that the drug should be ready for use later this year and in time for any potential winter outbreak of the virus, which has infected 4.8 million people around the world and killed more than 315,000.

"Planning for the clinical trial is underway," said Xie, adding it will be carried out in Australia and other countries since cases have dwindled in China, offering fewer human guinea pigs for testing.

"The hope is these neutralised antibodies can become a specialised drug that would stop the pandemic," he said.

China already has five potential coronavirus vaccines at the human trial stage, a health official said last week.

But the World Health Organization has warned that developing a vaccine could take 12 to 18 months.

Scientists have also pointed to the potential benefits of plasma -- a blood fluid -- from recovered individuals who have developed antibodies to the virus enabling the body's defences to attack it.

More than 700 patients have received plasma therapy in China, a process which authorities said showed "very good therapeutic effects".

"However, it (plasma) is limited in supply," Xie said, noting that the 14 neutralising antibodies used in their drug could be put into mass production quickly.

Using antibodies in drug treatments is not a new approach, and it has been successful in treating several other viruses such as HIV, Ebola and Middle East Respiratory Syndrome (MERS).

Xie said his researchers had "an early start" since the outbreak started in China before spreading to other countries.

Ebola drug Remdesivir was considered a hopeful early treatment for COVID-19 -- clinical trials in the US showed it shortened the recovery time in some patients by a third -- but the difference in mortality rate was not significant.

The new drug could even offer short-term protection against the virus.

The study showed that if the neutralising antibody was injected before the mice were infected with the virus, the mice stayed free of infection and no virus was detected.

This may offer temporary protection for medical workers for a few weeks, which Xie said they are hoping to "extend to a few months".

More than 100 vaccines for COVID-19 are in the works globally, but as the process of vaccine development is more demanding, Xie is hoping that the new drug could be a faster and more efficient way to stop the global march of the coronavirus.

"We would be able to stop the pandemic with an effective drug, even without a vaccine," he said.

Wuhan, Feb 9: President Xi Jinping strode onstage before an adoring audience in the Great Hall of the People in Beijing less than three weeks ago, trumpeting his successes in steering China through a tumultuous year and promising "landmark" progress in 2020.

"Every single Chinese person, every member of the Chinese nation, should feel proud to live in this great era," he declared to applause on the day before the Lunar New Year holiday. "Our progress will not be halted by any storms and tempests."

Xi made no mention of a dangerous new coronavirus that had already taken tenacious hold in the country. As he spoke, the government was locking down Wuhan, a city of 11 million people, in a frantic attempt to stop the virus spreading from its epicenter.

The coronavirus epidemic, which has killed more than 800 people in China as of Sunday and sickened tens of thousands, comes as Xi has struggled with a host of other challenges: a slowing economy, huge protests in Hong Kong, an election in Taiwan that rebuffed Beijing and a protracted trade war with the United States.

Now Xi faces an accelerating health crisis that is also a political one: a profound test of the authoritarian system he has built around himself over the past seven years. As the Chinese government struggles to contain the virus amid rising public discontent with its performance, the changes that Xi has ushered in could make it difficult for him to escape blame.

"It’s a big shock to the legitimacy of the ruling party. I think it could be only second to the June 4 incident of 1989. It’s that big," said Rong Jian, a writer about politics in Beijing, referring to the armed crackdown on Tiananmen Square protesters that year.

"There’s no doubt about his control over power," he added, "but the manner of control and its consequences have hurt his legitimacy and reputation."

Xi himself has recognized what is at stake, calling the outbreak "a major test of China’s system and capacity for governance."

Yet as China’s battle with the coronavirus intensified, Xi put the country’s No. 2 leader, Li Keqiang, in charge of a leadership group handling the emergency, effectively turning him into the public face of the government’s response. It was Li Keqiang who traveled to Wuhan to visit doctors.

Xi, by contrast, receded from public view for several days. That was not without precedent, though it stood out in this crisis, after previous Chinese leaders had used times of disaster to try to show a more common touch. State television and newspapers almost always lead with fawning coverage of Xi’s every move.

That retreat from the spotlight, some analysts said, signaled an effort by Xi to insulate himself from a campaign that may falter and draw public ire. Yet Xi has consolidated power, sidelining or eliminating rivals, so there are few people left to blame when something goes wrong.

"Politically, I think he is discovering that having total dictatorial power has a downside, which is that when things go wrong or have a high risk of going wrong, then you also have to bear all the responsibility," said Victor Shih, an associate professor at the University of California San Diego who studies Chinese politics.

Much of the country’s population has been told to stay at home, factories remain closed, and airlines have cut service. Experts warn that the coronavirus could slam the economy if not swiftly contained.

The government is also having trouble controlling the narrative. Xi now faces unusually sharp public discontent that even China’s rigorous censorship apparatus has been unable to stifle entirely.

The death of an ophthalmologist in Wuhan, Dr. Li Wenliang, who was censured for warning his medical school classmates of the spread of a dangerous new disease in December, has unleashed a torrent of pent-up public grief and rage over the government’s handling of the crisis. Chinese academics have launched at least two petitions in the wake of Li’s death, each calling for freedom of speech.

State media still portray Xi as ultimately in control, and there’s no sign that he faces a serious challenge from within the party leadership. The crisis, though, has already tainted China’s image as an emerging superpower — efficient, stable and strong — that could eventually rival the United States.

How much the crisis might erode Xi’s political standing remains to be seen, but it could weaken his position in the long run as he prepares to take a likely third term as Communist Party general secretary in 2022.

In 2018, Xi won approval to remove the constitutional limits on his term as the country’s president, making his plan for another five-year term seem all but certain.

If Xi comes out of this crisis politically insecure, the consequences are unpredictable. He may become more open to compromise within the party elite. Or he may double down on the imperious ways that have made him China’s most powerful leader in generations.

"Xi’s grip on power is not light," said Jude Blanchette, the Freeman Chair in China Studies at the Center for Strategic and International Studies.

"While the ham-fisted response to this crisis undoubtedly adds a further blemish to Xi’s tenure in office," Blanchette added, "the logistics of organizing a leadership challenge against him remain formidable."

In recent days, despite a dearth of public appearances, state media have portrayed Xi as a tireless commander-in-chief. This week they began calling the government’s fight against the virus the "people’s war," a phrase used in the official readout of Xi’s telephone call with President Donald Trump on Friday.

There are increasing signs that the propaganda this time is proving less than persuasive.

The Lunar New Year reception in Beijing where Xi spoke became a source of popular anger, a symbol of a government slow to respond to the suffering in Wuhan. Xi and other leaders appear to have been caught off guard by the ferocity of the epidemic.

Senior officials would almost certainly have been informed of the emerging crisis by the time national health authorities told the World Health Organization on Dec. 31, but neither Xi nor other officials in Beijing informed the public.

Xi’s first acknowledgment of the epidemic came Jan. 20, when brief instructions were issued under his name. His first public appearance after the lockdown of Wuhan on Jan. 23 came two days later, when he presided over a meeting of the Communist Party’s top body, the Politburo Standing Committee, which was shown at length on Chinese television. "We’re sure to be able to win in this battle," he proclaimed.

Back then, the death toll was 106. As it rose, Xi allowed other officials to take on more visible roles. Xi’s only appearances have been meeting foreign visitors in the Great Hall of the People or presiding over Communist Party meetings.

On Jan. 28, Xi met with the executive director of the World Health Organization, Dr. Tedros Adhanom Ghebreyesus, and told Tedros that he "personally directed" the government’s response. Later reports in state media omitted the phrase, saying instead that Xi’s government was "collectively directing" the response.

Since nothing about how Xi is portrayed in state media happens by accident, the tweak suggested a deliberate effort to emphasize shared responsibility.

Xi did not appear on official broadcasts again for a week — until a highly scripted meeting Wednesday with the authoritarian leader of Cambodia, Hun Sen.

There is little evidence that Xi has given up power behind the scenes. Li Keqiang, the premier in formal charge of the leadership group for the crisis, and other officials have said that they take their orders from Xi. The group is filled with officials who work closely under Xi, and its directives emphasize his authority.

"The way the epidemic is being handled now from the top just doesn’t fit with the argument that there’s been a clear shift toward more collective, consultative leadership," said Holly Snape, a British Academy Fellow at the University of Glasgow who studies Chinese politics.

The scale of discontent and the potential challenges for Xi could be measured by repeated references online to the nuclear accident at Chernobyl. Many of them came under the guise of viewer reviews of the popular television miniseries of the same name, which is still available for streaming inside China.

"In any era, any country, it’s the same. Cover everything up," one reviewer wrote.

The Soviet Union of 1986, however, was a different country than China in 2020.

The Soviet state was foundering when Chernobyl happened, said Sergey Radchenko, a professor of international relations at Cardiff University in Wales who has written extensively on Soviet and Chinese politics.

"The Chinese authorities, by contrast, are demonstrating an ability to cope, a willingness to take unprecedented measures — logistical feats that may actually increase the regime’s legitimacy," he added.

Radchenko compared Xi’s actions to those of previous leaders in moments of crisis: Mao Zedong after the Cultural Revolution or Deng Xiaoping after the Tiananmen Square crackdown.

"He’s doing what Mao and Deng would have done in similar circumstances: stepping back into the shadows while remaining firmly in charge."

Washington, Jul 14: Florida on Sunday reported a record 15,300 new coronavirus cases, the most by any state in a single day even as the coronavirus cases in the country have surged to 3,363,056.

The Washington Post reported that the huge number was result of both increased testing and widespread community transmission. The numbers shattered previous highs of 11,694 reported by California last week and 11,571 reported by New York on April 15.

Natalie E. Dean, an assistant professor of biostatistics at the University of Florida wrote that with Florida largely open for business, he doesn't expect this surge to slow.

Nationally, the conversation over reopening has become increasingly fraught amid the newly soaring case numbers, with much of the debate centering on whether schools should open their doors in the fall, reported the Post.

The Health workers in California and Texas too are facing an influx of COVID-19 patients where officials reported seven day averages for new cases - 8,664 and 9060 respectively.

According to the report, Florida has reported nearly 70,000 cases in last week alone, the most of any state.

Even though the COVID-19 cases are surging, Florida Gov. Ron DeSantis has stuck to an aggressive reopening plan with state officials recently ordering schools to reopen five days a week in the new academic year.

The state is also set to hold the Republican National Convention next month in Jacksonville's VyStar Veterans Memorial Arena, an indoor facility that seats about 15,000, reported Washington Post.

Seven-day averages for new cases -- considered a more reliable indicator of the virus's impact than single-day totals -- hit new highs in Alabama, Florida, Mississippi, Montana, North Carolina, Oklahoma and Puerto Rico.
