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.

Hong Kong, Apr 20: Oil prices collapsed to more than two-decade lows Monday as traders grow concerned that storage facilities are reaching their limits, while equities were mixed, with some support coming from signs that the coronavirus may have peaked in Europe and the United States.

US crude benchmark West Texas Intermediate briefly plunged almost 20 percent to below 15 -- its lowest since 1999 -- as stockpiles continue to build owing to a crash in demand caused by the COVID-19 pandemic.

Analysts said this month's agreement between top producers to slash output by 10 million barrels a day was having little impact on the oil crisis because of lockdowns and travel restrictions that are keeping billions of people at home.

WTI was hit particularly hard as its main US storage facilities in Cushing, Oklahoma, were filling up.

ANZ said "crude oil prices remained under pressure, as projections of weaker demand weigh on sentiment".

"Despite the OPEC+ alliance agreeing to an unprecedented cut in output, the physical market is awash with oil," it said, referring to the Organization of the Petroleum Exporting Countries and non-OPEC partners.

And AxiCorp's Stephen Innes added: "It's a dump at all cost as no one... wants delivery of oil, with Cushing storage facilities filling by the minute.

"It hasn't taken long for the market to recognise that the OPEC+ deal will not, in its present form, be enough to balance oil markets." Stock traders were in slightly more buoyant mood as governments start to consider how and when to ease lockdowns that have crippled the global economy.

Italy, Spain, France and Britain reported drops in daily death tolls and slowing infection rates.

"We are scoring points against the epidemic," said Prime Minister Edouard Philippe, while insisting "we are not out of the health crisis yet".

Meanwhile, in the US, Andrew Cuomo, governor of badly hit New York state, said the disease was "on the descent", though he cautioned it was "no time to get cocky".

Mounting evidence suggests that the lockdowns and social distancing are slowing the spread of the virus.

That has intensified planning in many countries to begin loosening curbs on movement and easing the crushing pressure on national economies.

Adding to the sense of hope was a report indicating promising research on a drug to treat coronavirus.

Hong Kong, Shanghai and Seoul were each up 0.1 percent, while Wellington added 0.4 percent.

However, Tokyo went into the break 0.9 percent lower, while Sydney and Manila dropped one percent apiece. There were also losses in Taipei, Singapore and Jakarta.

"The longer investors have to contemplate future economic issues while they wait for more countries to be on the downward slope of the pandemic curve, the more scope there is of risk assets pricing in a difficult future," Chris Iggo, of AXA Investment Managers UK, said.

Investors are keeping an eye on Washington, where Congress and the White House are working towards a 450 billion economic relief plan for small business to add to the trillions already pledged to support the economy.

Big-name companies including IBM, Netflix and Coca-Cola are due to deliver their earnings reports.

Mar 3: Just hours after the ending of a week-long “reduction” in violence that was crucial for Donald Trump’s peace deal in Afghanistan, the Taliban struck again: On Monday, they killed three people and injured about a dozen at a football match in Khost province. This resumption of violence will not surprise anyone actually invested in peace for that troubled country. The point of the U.S.-Taliban deal was never peace. It was to try and cover up an ignominious exit for the U.S., driven by an election-bound president who feels no responsibility toward that country or to the broader region.

Seen from South Asia, every point we know about in the agreement is a concession by Trump to the Taliban. Most importantly, it completes a long-term effort by the U.S. to delegitimize the elected government in Kabul — and, by extension, Afghanistan’s constitution. Afghanistan’s president is already balking at releasing 5,000 Taliban prisoners before intra-Afghan talks can begin — a provision that his government did not approve.

One particularly cringe-worthy aspect: The agreement refers to the Taliban throughout  as “the Islamic Emirate of Afghanistan that is not recognized by the United States as a state and is known as the Taliban.” This unwieldy nomenclature validates the Taliban’s claim to be a government equivalent to the one in Kabul, just not the one recognised at the moment by the U.S. When read together with the second part of the agreement, which binds the U.S. to not “intervene in [Afghanistan’s] domestic affairs,” the point is obvious: The Taliban is not interested in peace, but in ensuring that support for its rivals is forbidden, and its path to Kabul is cleared.

All that the U.S. has effectively gotten in return is the Taliban’s assurance that it will not allow the soil of Afghanistan to be used against the “U.S. and its allies.” True, the U.S. under Trump has shown a disturbing willingness to trust solemn assurances from autocrats; but its apparent belief in promises made by a murderous theocratic movement is even more ridiculous. Especially as the Taliban made much the same promise to an Assistant Secretary of State about Osama bin Laden while he was in the country plotting 9/11.

Nobody in the region is pleased with this agreement except for the Taliban and their backers in the Pakistani military. India has consistently held that the legitimate government in Kabul must be the basic anchor of any peace plan. Ordinary Afghans, unsurprisingly, long for peace — but they are, by all accounts, deeply skeptical about how this deal will get them there. The brave activists of the Afghan Women’s Network are worried that intra-Afghan talks will take place without adequate representation of the country’s women — who have, after all, the most to lose from a return to Taliban rule.

But the Pakistani military establishment is not hiding its glee. One retired general tweeted: “Big victory for Afghan Taliban as historic accord signed… Forced Americans to negotiate an accord from the position of parity. Setback for India.” Pakistan’s army, the Taliban’s biggest backer, longs to re-install a friendly Islamist regime in Kabul — and it has correctly estimated that, after being abandoned by Trump, the Afghan government will have sharply reduced bargaining power in any intra-Afghan peace talks. A deal with the Taliban that fails also to include its backers in the Pakistani military is meaningless.

India, meanwhile, will not see this deal as a positive for regional peace or its relationship with the U.S. It comes barely a week after Trump’s India visit, which made it painfully clear that shared strategic concerns are the only thing keeping the countries together. New Delhi remembers that India is not, on paper, a U.S. “ally.” In that respect, an intensification of terrorism targeting India, as happened the last time the U.S. withdrew from the region, would not even be a violation of Trump’s agreement. One possible outcome: Over time the government in New Delhi, which has resolutely sought to keep its ties with Kabul primarily political, may have to step up security cooperation. Nobody knows where that would lead.

The irresponsible concessions made by the U.S. in this agreement will likely disrupt South Asia for years to come, and endanger its own relationship with India going forward. But worst of all, this deal abandons those in Afghanistan who, under the shadow of war, tried to develop, for the first time, institutions that work for all Afghans. No amount of sanctimony about “ending America’s longest war” should obscure the danger and immorality of this sort of exit.

Hubei, Mar 25: As a bus departed from its terminus at Hankou Railway Station at 5:25 am Wednesday morning, Wuhan started to resume bus service after nine weeks of lockdown.

Apart from a driver, a safety supervisor was also on each bus, whose duty was to make sure all passengers are healthy.
"For those who do not use smartphones, they should bring with them a health certificate issued by the health authorities," said Zhou Jingjing, a safety supervisor aboard bus No. 511 departing from the Wuchang Railway Station complex.
The once hardest-hit city in central China's Hubei Province during the COVID-19 outbreak took unprecedented traffic restrictions on Jan 23. All of its public transport and all outbound flights and trains had been suspended in an attempt to contain the virus within the region.
