Italian researchers claim world’s first COVID-19 vaccine: Report

Italian researchers have claimed that they have successfully developed a vaccine to contain coronavirus (COVID-19) which is likely to work on humans, a report said.

Luigi Aurisicchio, CEO of Takis, the firm developing the medication, said that a coronavirus candidate vaccine has neutralised the virus in human cells for the first time, the Arab News reported.

"This is the most advanced stage of testing of a candidate vaccine created in Italy. Human tests are expected after this summer," Aurisicchio was quoted as saying to Italian news agency ANSA.

"According to the Spallanzani Hospital, as far as we know we are the first in the world so far to have demonstrated neutralisation of the coronavirus by a vaccine. We expect this to happen in humans too," he added.

The researchers experimented with the vaccine on mice that had successfully developed antibodies that blocked the virus from infecting the cells. They further observed that the five vaccine candidates generated a large number of antibodies, and selected two with the best results.

All of the vaccine candidates currently being developed are based on the genetic material of DNA protein "spike", the molecular tip used by the coronavirus to enter human cells.

They are injected with the so-called "electroporation" technique, which consists of an intramuscular injection followed by a brief electrical impulse, helping the vaccine break into the cells and activating the immune system, the report said.

Researchers believe that this makes their vaccine particularly effective for generating functional antibodies against the "spike" protein, in particular in the lung cells, which are the most vulnerable to coronavirus.

"We are working hard for a vaccine coming from Italian research, with an all-Italian and innovative technology, tested in Italy and made available to everyone," Aurisicchio was quoted by the Arab News report.

"In order to reach this goal, we need the support of national and international institutions and partners who may help us speed up the process," he noted.

The total number of COVID-19 infections, fatalities and recoveries since the pandemic began has risen to 213,013 in the country.

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."

Jun 4: A malaria drug President Donald Trump took to try to prevent COVID-19 proved ineffective for that in the first large, high-quality study to test it in people in close contact with someone with the disease.

Results published Wednesday by the New England Journal of Medicine show that hydroxychloroquine was no better than placebo pills at preventing illness from the coronavirus.

The drug did not seem to cause serious harm, though -- about 40% on it had side effects, mostly mild stomach problems.

 “We were disappointed. We would have liked for this to work,” said the study leader, Dr. David Boulware, an infectious disease specialist at the University of Minnesota.

“But our objective was to answer the question and to conduct a high-quality study,” because the evidence on the drug so far has been inconclusive, he said.

Hydroxychloroquine and a similar drug, chloroquine, have been the subject of much debate since Trump started promoting them in March.

Hydroxychloroquine has long been used for malaria, lupus, and rheumatoid arthritis, but no large studies have shown it or chloroquine to be safe or effective for much sicker patients with coronavirus, and some studies have suggested the drugs may do harm.

Trump took a two-week course of hydroxychloroquine, along with zinc and Vitamin D, after two staffers tested positive for COVID-19, and had no ill effects, according to results of his latest physical released by his doctor Wednesday.

Federal regulators have warned against hydroxychloroquine's use except in hospitals and formal studies because of the risk of side effects, especially heart rhythm problems.

Boulware's study involved 821 people in the United States and Canada living with someone diagnosed with COVID-19 or at high risk of getting it because of their job -- doctors, nurses, ambulance workers who had significant exposure to a sick patient while not wearing full protective gear.

They were randomly assigned to get either the nutrient folate as a placebo or hydroxychloroquine for five days, starting within four days of their exposure. Neither they nor others involved in the research knew who was getting which pills.

After 14 days in the study, 12 per cent on the drug developed COVID-19 symptoms versus 14 per cent in the placebo group, but the difference is so small it could have occurred by chance, Boulware said.

“There's basically no effect. It does not prevent infection,” he said of the drug. Even if it were to give some slim advantage, “we'd want a much larger effect” to justify its use and risk of side effects for preventing illness, he said.

Results were no different among a subgroup of participants who were taking zinc or vitamin C, which some people believe might help make hydroxychloroquine more effective or fight the coronavirus.

There are some big caveats: The study enrolled people through the Internet and social media, relying on them to report their own symptoms rather than having them tracked in a formal way by doctors.

Participants were not all tested for the coronavirus but were diagnosed as COVID-19 cases based on symptoms in many cases. And not all took their medicines as directed.

The results “are more provocative than definitive,” and the drug may yet have prevention benefits if tried sooner or in a different way, Dr. Myron Cohen of the University of North Carolina at Chapel Hill wrote in a commentary in the journal.

Others were glad to see a study that had a comparison group and good scientific methods after so many weaker reports on hydroxychloroquine.

“This fits with everything else we've seen so far which suggests that it's not beneficial," said Dr. Peter Bach, director of a health policy center at Memorial Sloan Kettering Cancer Center in New York.

This study was in younger relatively healthy people, but the results “would make me very discouraged about trying to use this in older people” who are most vulnerable to serious illness from the coronavirus, Bach said.

“If it does work, it doesn't work very well.” Dr. Dan Culver, a lung specialist at the Cleveland Clinic, said there's still a chance that giving the drug sooner than four days after someone's exposure to the virus may help prevent illness.

But the study “takes 'home run' off the table” as far as hopes for the drug, he said.

The study was mostly funded by David Baszucki, founder of Roblox, a California-based game software company, and other private donors and the Minnesota university.

Boulware also is leading a study testing hydroxychloroquine for treating COVID-19. The study is finished and results are being analyzed now.

On Tuesday, the journal Lancet posted an “expression of concern” about a study it published earlier this month of nearly 15,000 COVID-19 patients on the malaria drugs that tied their use to a higher risk of dying in the hospital or developing a heartbeat problem.

Scientists have raised serious questions about the database used for that study, and its authors have launched an independent audit.

That work had a big impact: the World Health Organization suspended use of hydroxychloroquine in a study it is leading, and French officials stopped the drug's use in hospitals. On Wednesday, the WHO said experts who reviewed safety information decided that its study could resume.
