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.

United Nations, Jun 6: US President Donald Trump’s response to protests against the killing of African-American George Floyd has included language “directly associated with racial segregationists” from America's past, a group of UN human rights experts have said.

There have been widespread protests across the United States as Floyd, 46, was killed by a white police officer in Minneapolis. People from diverse backgrounds have called for justice and have voiced their support to the protests.

In the wake of protests over the killing of Floyd, Trump had tweeted that “when the looting starts, the shooting starts.”

“The response of the President of the United States to the protests at different junctures has included threatening more state violence using language directly associated with racial segregationists from the nation’s past, who worked hard to deny black people fundamental human rights," a statement issued on Friday by over 60 independent experts of the Special Procedures of the United Nations Human Rights Council said.

"We are deeply concerned that the nation is on the brink of a militarised response that reenacts the injustices that have driven people to the streets to protest,” it said.

A report in The New York Times had said that the phrase "When the looting starts, the shooting starts” was used by Miami’s former police chief Walter Headley in 1967. Headley had been “long accused of using racist tactics in his force’s patrols of black neighbourhoods,” the NYT had said.

They said the recent killing of Floyd has shocked many in the world, “but it is the lived reality of black people across the United States. The uprising nationally is a protest against systemic racism that produces state-sponsored racial violence, and licenses impunity for this violence.”

They noted that following the recent spate of killings of African-Americans, many in the United States and abroad are finally acknowledging that “the problem is not a few bad apples” but instead the problem is the very way that economic, political and social life are structured in a country that prides itself in liberal democracy, and with the largest economy in the world.

Separately, 28 UN experts called on the US Government to take decisive action to address systemic racism and racial bias in the country's criminal justice system by launching independent investigations and ensuring accountability in all cases of excessive use of force by police.

“Exactly 99 years after the massacre in Tulsa, involving the killing of people of African descent and the massive loss of life, destruction of property and loss of wealth on ‘Black Wall Street’, African Americans continue to experience racial terror in state-sponsored and privately organised violence,” the experts said.

Strongly condemning the killings of Ahmaud Arbery, Breonna Taylor and George Floyd, the experts called for systemic reform and justice. “Given the track record of impunity for racial violence of this nature in the United States, Black people have good reason to fear for their lives.”

Taylor, a 25-year-old emergency medical technician was shot in her bed when police raided the wrong house; Arbery, 25, was fatally shot while jogging near his home by three white men who chased and cornered him; and Floyd was accused of using counterfeit currency in a store and died in the street while a white officer knelt on his neck and three others participated and observed.

“The origin story of policing in the United States of America starts with slave patrols and social control, where human property of enslavers was ‘protected’ with violence and impunity against people of African descent. In the US, this legacy of racial terror remains evident in modern-day policing,” the experts said.

The experts also raised concern about the police response to demonstrations in several US cities, termed by some the ‘Fed Up-rising’, that have been marked by violence, arbitrary arrest, militarisation and the detention of thousands of protesters. Reporters of colour have been targeted and detained, and some journalists have faced violence and harassment.

“Statements from the US Government inciting and threatening violence against protesters stand in stark contrast to calls for leniency and understanding which the Government had issued in the wake of largely white protests against COVID-19 restrictions on services like barbershops, salons, and spas,” the experts said.

Six months since the new coronavirus outbreak, the pandemic is still far from over, the World Health Organization said Monday, warning that "the worst is yet to come".

Reaching the half-year milestone just as the death toll surpassed 500,000 and the number of confirmed infections topped 10 million, the WHO said it was a moment to recommit to the fight to save lives.

"Six months ago, none of us could have imagined how our world -- and our lives -- would be thrown into turmoil by this new virus," WHO chief Tedros Adhanom Ghebreyesus told a virtual briefing.

"We all want this to be over. We all want to get on with our lives. But the hard reality is this is not even close to being over.

"Although many countries have made some progress, globally the pandemic is actually speeding up.

"We're all in this together, and we're all in this for the long haul.

"We will need even greater stores of resilience, patience, humility and generosity in the months ahead.

"We have already lost so much -- but we cannot lose hope."

Tedros also said that the pandemic had brought out the best and worst humanity, citing acts of kindness and solidarity, but also misinformation and the politicisation of the virus.

In an atmosphere of global political division and fractures on a national level, "the worst is yet to come. I'm sorry to say that," he said.

"With this kind of environment and condition, we fear the worst."
