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.

Beijing, Mar 12: The number of fresh infections at the epicentre of China's coronavirus epidemic dropped to a new low on Thursday but the country imported more cases from abroad.

Another 11 people died, the lowest daily increase since late January, bringing the toll in China to 3,169 deaths, according to the National Health Commission.

There were only eight new cases in Wuhan, the city where the virus first emerged in December before growing into a national crisis and a pandemic.

It is the first time that new cases in Wuhan, the capital of Hubei province, have fallen to single-digits since figures started to be reported in January.

With cases falling dramatically in recent weeks, authorities this week began to loosen some restrictions on Hubei's 56 million people, who have been under quarantine since late January.

Healthy people living in low-risk areas of the province can now travel within Hubei. While Wuhan is not included, some of the city's companies were told they could resume work.

Only one other non-imported case was recorded elsewhere in the country.

But as global hotspots emerge elsewhere, China fears that cases arriving from abroad could undermine its progress.

On Thursday there were six more imported cases reported, bringing the total of infections from overseas to 85, health officials said.

Beijing has ordered a 14-day quarantine for everyone arriving in the city from any country.

Travellers flying into Beijing Capital International Airport from high-risk countries are now handled separately from other passengers.

A total of 80,793 people have now been infected in China.

President Xi Jinping said this week during his first visit to Wuhan since the crisis erupted that the spread of the disease has been "basically curbed" in China.

Washington, May 30: US President Donald Trump on Friday said that America is terminating its relationship with the World Health Organization as he blamed it and China for the deaths and destruction caused by the COVID-19 pandemic across the globe.

Stating that the funding of the WHO would now be diverted to other global public health organisations, Trump announced a series of decisions against China including issuing proclamation to deny entry to certain Chinese nationals and tightening of regulations against Chinese investments in America.

"Because they (WHO) have failed to make the requested and greatly needed reforms, we will be today terminating our relationship with the World Health Organization and redirecting those funds to other worldwide and deserving urgent global public health needs, Trump said.

Singapore, Jul 11: Singapore Prime Minister Lee Hsien Loong has secured a “clear mandate” with his ruling People’s Action Party (PAP) winning 83 of the 93 contested parliamentary seats in the general election held amidst the Covid-19 pandemic, with the Opposition gaining ground by winning a record 10 seats.

The ruling party, in power since independence in 1965, secured 61.24 percent of the total votes cast in the election, down from 69.9 percent in 2015. About 2.6 million Singaporeans voted on Friday.

“We have a clear mandate, but the percentage of the popular vote is not as high as I had hoped for,” 68-year old Lee told a PAP’s post-results press conference on Saturday morning.

The opposition Workers’ Party secured 10 seats and defeated a team in the Group Representation Constituency of Sengkang led by former Minister in the Prime Minister’s Office Ng Chee Meng who is also the Secretary-General of the power National Trades Union Congress (NTUC).

The Prime Minister assured it is “only right” that Workers’ Party’s Indian-origin secretary-general Pritam Singh be “formally designated” as the Leader of the Opposition, and that he will be provided with “appropriate staff support and resources to perform his duties”.

Lee took the results in “these circumstances” as an “endorsement” of the party’s policies and plans as he had called the elections amidst Covid-19 pandemic.

“We’ll take this forward and work with Singapore to realise those plans and solve the problems which we have,” Channel News Asia quoted the premier as saying.

Lee, who leads the PAP as secretary-general, said, “Singaporeans understand what’s at stake and why we must come together to uphold our national interests.”

He pledged to use this mandate “responsibly” to deal with the Covid-19 situation and economic downturn, to take Singapore “safely through the crisis and beyond”.

“The results reflect the pain and uncertainty that Singaporeans feel in this crisis, the loss of income, the anxiety about jobs, the disruption caused by the circuit breaker and the safe distancing restrictions,” he said.

This was not a “feel-good” election, said Lee, Singapore’s third prime minister who faces the city state’s worst recession with the economy projected to shrink between 7 and 4 per cent.

Lee acknowledged that the result also showed a “clear desire” for a diversity of voices in Parliament.

“Singaporeans want the PAP to form the government, but they, and especially the younger voters, also want to see more opposition presence in parliament,” he noted.

Lee added that he looks forward to the participation and contribution of the Opposition in parliament.

Singh, whose Workers’ Party team retained Aljunied Group Representation Constituency (GRC), will have 10 elected MPs now, up from six previously. His fellow member also retained the Hougang single-member constituency seat.

“Whether it works out… and whether it’s seen as a strengthening of Singapore will depend not only on what the PAP does but also on what the Opposition does because the Opposition now has 10 MPs elected from constituencies,” said Lee.

He assured that the ruling party will listen to Singaporeans and do its best to address their concerns, and “try to win” their support, whether or not they voted for the PAP.

When asked by the media if the party had lost the youth vote, he noted that different generations have different life experiences, and the young have significantly different life aspirations and priorities compared to the older generations.

“That’ll have to be reflected in our political process and in the government’s policies because, in the end, the government’s policies must be to achieve the aspirations of every generation of Singaporeans,” Lee said, assuring Singaporeans.

He hoped that the new generations of Singaporeans “look critically, but with an open mind” at what previous generations have done, “examine what’s relevant and what continues to make sense to them in a new environment” and “learn from these experiences hard-won by their parents and grandparents”.

This is so that they do not have to “learn them all over again and pay a high price which has already been paid”.

Lee added that he was, naturally, disappointed at the loss of the newly formed Sengkang GRC, which the Workers’ Party won with 52.13 percent of the valid votes.

“Ng Chee Meng and his team -- Lam Pin Min, Amrin Amin and Raymond Lye -- always knew it was going to be a tough fight,” he said.

“They gave it their all, but Sengkang voters have spoken, and we respect their decision.”

Lee described it as a “major loss to my team” and to the fourth-generation leaders, especially as Ng is the secretary-general of the Labour Movement, the NTUC.

Singh, 43, told a press conference following the results that his team would “continue to endeavour for good outcomes on the ground” and to represent voters “faithfully in parliament”.

“Today’s results are positive, but we have to hit the ground running. We should not get over our head with the results. There’s much work to do. And I can assure you this Workers’ Party team is committed to serve Singapore,” he stressed.

The PAP contested all 93 seats and the Workers’ Party 21 seats. Nine other political parties also contested the elections.

A total of 192 candidates contested for seats through 17 Group Representation Constituencies (GRCs).
