Paris, Jul 20: Two coronavirus vaccine candidates have proven safe for humans and produced strong immune reactions among patients involved in separate clinical trials, doctors said on Monday.

The first trial among more than 1,000 adults in Britain found that the vaccine induced "strong antibody and T cell immune responses" against the novel coronavirus.

A separate trial in China involving more than 500 people showed most had developed widespread antibody immune response.

The studies, published in The Lancet medical journal, constitute a major step on the road towards a COVID-19 vaccine that is effective and safe for widespread use.

The authors of the studies said that they encountered few adverse side-effects from the vaccine candidates.

However, they cautioned that more research was needed, particularly among older adults, who are disproportionately at risk of dying of COVID-19.

Co-author Sarah Gilbert from the University of Oxford said the results "hold promise".

"If our vaccine is effective, it is a promising option as these types of vaccine can be manufactured at large scale."

Ramallah, Jul 2: Several world countries renew a call for Israel to halt contentious plans to annex parts of the occupied Palestinian territory after the regime delayed the implementation of the land garb bid in the face of a series of stumbling blocks, including internal rifts, global criticisms and the US’s failure to give Tel Aviv the go-ahead for the move.

Israel's ruling coalition, led by Prime Minister Benjamin Netanyahu, had announced July 1 as the date to begin moving forward with the plan to impose Tel Aviv’s “sovereignty” over about a third of the West Bank, including settlements and the fertile Jordan Valley.

Without clarifications, the regime, however, failed to launch the scheme on the set date amid widening differences between Netanyahu and his coalition partner, minister of military affairs Benny Gantz.

Meanwhile, there are signs that the administration of US President Donald Trump, a staunch Israel supporter, has cooled its backing for the Israeli move amid what is believed to be troubles at home and fears that it might hurt the president’s chances of re-election besides international pressure.

On Wednesday, Netanyahu's office said in a statement that he would continue to discuss a possible West bank annexation with the US administration.

“In the coming days there will be additional discussions,” the statement said.

Labor, Social Affairs and Social Services Minister Ofir Akunis said the Israel would annex portions of the West Bank in July but only after the US president issued a declaration on the matter.

The annexation “will only happen after a declaration by Trump,” he told Israeli Army Radio.

Trump had already given Tel Aviv the green light for the land grab in his self-proclaimed “deal of the century,” which was unveiled in January with the aim of re-drawing the Middle East map.

However, the Trump administration has so far refrained from offering official support for the annexation sought by Netanyahu and his right-wing allies.

Unlike the US, several countries, including some of Israel’s allies, have expressed their opposition to Israel’s planned push to consolidate its occupation of Palestine.

Germany passes anti-annexation resolution

On Wednesday, the German parliament approved a resolution calling on the government to dissuade Israel from annexing the West Bank.

The motion, which was brought in the German legislature by the three parties in Chancellor Angela Merkel's coalition, was approved without opposing votes. 

Berlin should use its “special relations and contacts [with Tel Aviv] to express to the Israeli government our concerns and our urgent demand to refrain from an annexation of parts of the West Bank and from the continued expansion of settlements, both of which contradict international law,” read the resolution.

Speaking at the parliamentary debate before the vote, German Foreign Minister Heiko Maas said, “We reject unilateral changes of borders, and we won’t recognize them.”

He also stressed that peace “cannot be achieved through unilateral steps but only through serious negotiations.”

France warns of consequences

Similarly, French Foreign Minister, Jean-Yves Le Drian warned that any Israeli annexation would be a violation of international law and would bring about consequences.

“Annexation of Palestinian territories, whatever the perimeters, would seriously throw into question the parameters to resolve the conflict,” he told a parliamentary hearing. 

The top diplomat added, “An annexation decision could not be left without consequences and we are examining different options at a national level and also in coordination with our main European partners.”

Australia raises concerns

Additionally, Australian Foreign Minister Marise Payne voiced worries about the Israeli scheme, saying she had directly expressed this view to Israeli Foreign Minister Gabi Ashkenazi.

“We are following with concern possible moves towards the unilateral annexation or change in status of territory on the West Bank,” she said in a statement.

“The focus needs to be on a return to direct and genuine negotiations between Israel and the Palestinians for a durable and resilient peace arrangement, as soon as possible,” Payne added.

Vatican summons US, Israeli envoys

Meanwhile, the Vatican announced on Wednesday that it had summoned the American and Israeli ambassadors to protest Israel’s annexation bid.

In separate meetings, Vatican Secretary of State Cardinal Pietro Parolin told Israeli Ambassador Oren David and US Ambassador Callista Gingrich of concerns “regarding possible unilateral actions that may further jeopardize the search for peace between Israelis and Palestinians, as well as the delicate situation in the Middle East,”

“As already declared … the Holy See reiterates that ... Israel and the State of Palestine have the right to exist and to live in peace and security, within internationally recognized borders,” the Vatican said in a statement.

“It thus appeals to the parties to do everything possible to reopen the process of direct negotiation, on the basis of the relevant Resolutions of the United Nations,” it added.

Amnesty urges firm action

Amnesty International called on the international community to take firm action against Israel’s annexation plan and its “law of the jungle” mentality.

“Members of the international community must enforce international law and restate that annexation of any part of the occupied West Bank is null and void,” said Saleh Higazi, deputy regional director for Amnesty Middle East and North Africa.

“They must also work to immediately stop the construction or expansion of illegal Israeli settlements and related infrastructure in the Occupied Palestinian Territories as a first step towards removing Israeli civilians living in such settlements,” he added.

Palestinians mark ‘Day of Rage'

Also on Wednesday, Palestinians held “Day of Rage” rallies both in the West Bank and the Gaza Strip against the Israeli expansionism.

In Gaza city, several thousand protesters gathered, some brandishing Palestinian national flags and placards condemning Trump.

Some demonstrators carried signs in English reading, “We Can’t Breathe Since 1948” and “Palestinian Lives Matter,” in reference to the American Black Lives Matter movement.

“The occupation has killed us and killed our children and deprived us of a good life. May God grant the Resistance victory,” a protester told the al-Aqsa TV.

“The resistance must be revived,” Gaza protester Rafeeq Inaiah told media persons. “Israel is afraid of force.”

Similar demonstrations also took place in the West Bank cities of Ramallah and Jericho.

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, Jun 9: China on Tuesday dismissed as "incredibly ridiculous" a Harvard study, which pointed to a surge in traffic outside Wuhan hospitals from August 2019 suggesting that the coronavirus hit the area far earlier than reported.

A whitepaper on coronavirus released by China on Sunday said the virus was first noticed on December 17 and Chinese virologists confirmed human-to-human transmission on January 19, prompting authorities to impose lockdown of Wuhan from January 23.

US President Donald Trump and leaders of several countries have accused China of not being transparent in reporting the deadly disease, leading to huge human casualties and economic crisis across the world.

The new study by Harvard researchers says satellite images show an increase in traffic outside five hospitals in Wuhan from late August to December.

The traffic spike coincided with a rise in online searches for information on symptoms like "cough" and "diarrhoea".

China said the study was "ridiculous" and based on "superficial" information, BBC reported.

It is believed that the virus first appeared in China some time in November. Authorities reported a cluster of pneumonia cases with an unknown cause to the World Health Organization (WHO) on December 31.

"Clearly, there was some level of social disruption taking place well before what was previously identified as the start of the novel coronavirus pandemic," Dr John Brownstein, who led the research, told ABC news.

The study has not been peer-reviewed.

The researchers examined commercial satellite data from outside five Wuhan hospitals, comparing data from late summer and autumn 2018 to the same time period in 2019.

In one case, researchers counted 171 cars parked at one of Wuhan''s largest hospitals, Tianyou Hospital, in October 2018.

Satellite data from the same time in 2019 showed 285 vehicles in the same place, an increase of 67 per cent.

A surge in online searches for words associated with the symptoms of coronavirus on the Chinese search engine Baidu seemed to emerge at the same time.

"This is all about a growing body of information pointing to something taking place in Wuhan at the time," Dr Brownstein said.

"Many studies are still needed to fully uncover what took place and for people to really learn about how these disease outbreaks unfold and emerge in populations. So this is just another point of evidence," he said.

Asked for her reaction at the media briefing, Chinese Foreign Ministry spokeswoman Hua Chunying dismissed the findings as "incredibly ridiculous".

"I think it is ridiculous, incredibly ridiculous, to come up with this conclusion based on superficial observations such as traffic volume," she said.

"(I have) Not seen the research you mentioned. If the conclusion is drawn based on traffic volumes (and) other superficial observations, it won’t be a sound conclusion," she said and referred to the allegations about the COVID-19 originating from the Wuhan Institute of Virology (WIV) by Trump.

"That allegation was proved to be wrong," she said.

When pointed out that China says it respects science based inquiry and Harvard is one of the top universities in the world, Hua said, "on the origin of virus there are lot of conspiracy theories against China”.

"That is very unfair. At the moment, the pressing task is to enhance coordination to contain the spread of the virus. Someday, I am sure the truth will be out. China deserves a fair and objective evaluation," she said and referred to the whitepaper released by the Chinese government detailing evolution of coronavirus in Wuhan and how Beijing handled the situation.

Recently, the World Health Assembly (WHA), the decision-making body of Geneva-based World Health Organization (WHO), passed a resolution to probe the origin of the virus. China also backed the resolution.

As of Monday, the overall confirmed cases on the mainland had reached 83,043, including 58 patients who were still being treated, with no one in severe condition, China’s National Health Commission, (NHC) said.

Altogether 78,351 people had been discharged after recovery and 4,634 people had died of the disease, it said.
