Canadian researchers are developing a DNA vaccine for SARS-CoV-2, the coronavirus that causes COVID-19 and has currently infected nearly 5,00,000 people worldwide and crippled the global economy.

Entos Pharmaceuticals, a health-care biotechnology company headed by a University of Alberta researchers, develop new therapeutic compounds using the company's proprietary drug-delivery platform and has begun manufacturing vaccine candidates against the novel coronavirus.

"Given the urgency of the situation, we can have a lead candidate vaccine within two months. Once we have that it's a race to get it into clinical trials," said John Lewis, CEO of Entos and a Professor at the University of Alberta in Canada.

Lewis said in comparison to a traditional vaccine, DNA-based vaccines hold several advantages.

Nucleic acids are introduced directly into the patient's own cells, causing them to make pieces of the virus--tricking the immune system into mounting a response without the full virus actually being present, the researcher said.

According to the company, the approach is recognised as being easier to move into large-scale manufacturing, offers improved vaccine stability and works without needing an infectious agent.

In the current absence of a vaccine for COVID-19, several companies around the world are mounting efforts to begin similar work.

The first clinical trial using a DNA-based vaccine developed by Moderna Inc.in the US on March 13.

Their approach allows for antibodies to be made in the human trial volunteers against a specific protein on the surface of the coronavirus that lets the virus enter human cells.

The hope is that the antibodies will stop the interaction.

Though this approach is designed to be effective against COVID-19 specifically, Lewis said Entos is taking a different tack.

The company plans to use plasmid DNA to amplify the production of key coronavirus surface and structural proteins with each injection, with an eye to the bigger picture.

"Many of the structural proteins in the virus are pretty well conserved across all the coronaviruses, including SARS and MERS," said Lewis.

"We're hoping that if we express more of the structural proteins that are common to most coronaviruses, we can inhibit the current COVID-19, and also potentially protect against all coronaviruses both past and future," Lewis added.

To move the project forward quickly, the company is seeking financial support from both provincial and federal levels of government.

"We have the opportunity to save a lot of lives, and I think it's really upon us and governments to find solutions for that," Lewis said.

Madrid, Mar 26: More than three billion people around the world were living under lockdown on Wednesday as governments stepped up their efforts against the coronavirus pandemic which has left more than 20,000 people dead.

As the number of confirmed cases worldwide soared past 450,000, UN Secretary General Antonio Guterres warned that only a concerted global effort could stop the spread of the virus.

In Spain, the number of fatalities surpassed those of China, where the novel coronavirus first emerged three months ago, making it the hardest-hit nation after Italy.

A total of more than 20,800 deaths have now been reported in 182 countries and territories, according to an AFP tally.

Stock markets rebounded after the US Congress moved closer to passing a $2.2 trillion relief package to prop up a teetering US economy.

In Washington, President Donald Trump said New York, the epicenter of the US outbreak with over 30,000 cases, likely has a few "tough weeks" ahead but he would decide soon whether unaffected parts of the country can get back to work.

"We want to get our country going again," Trump said. "I'm not going to do anything rash or hastily.

"By Easter we'll have a recommendation and maybe before Easter," said Trump, who had been touting a strong US economy as he faces an election in November.

UN chief Guterres said the world needs to ban together to stem the pandemic.

"COVID-19 is threatening the whole of humanity -- and the whole of humanity must fight back," Guterres said, launching an appeal for $2 billion to help the world's poor.

"Global action and solidarity are crucial," he said. "Individual country responses are not going to be enough."

India's stay-at-home order for its 1.3 billion people is now the biggest, taking the total number of individuals facing restrictions on their daily lives to more than three billion.

Anxious Indians raced for supplies after the world's second-biggest population was ordered not to leave their houses for three weeks.

Russia, which announced the death of two patients who tested positive for coronavirus on Wednesday, is expected to follow suit.

President Vladimir Putin declared next week a public holiday and postponed a public vote on controversial constitutional reforms, urging people to follow instructions given by authorities.

In Britain, heir to the throne Prince Charles became the latest high-profile figure to be infected, though he has suffered only mild symptoms.

The G20 major economies will hold an emergency videoconference on Thursday to discuss a global response to the crisis, as will the 27 leaders of the European Union, the outbreak's new epicenter.

China has begun to relax its own draconian restrictions on free movement in the province of Hubei -- where the outbreak began in December -- after the country reported no new cases.

Crowds jammed trains and buses in the province as people took their first opportunity to travel.

But Spain saw the number of deaths surge to more than 3,400 after 738 people died in the past 24 hours and the government announced a 432-million-euro ($467 million) deal to buy medical supplies from Beijing.

The death toll in Italy jumped in 24 hours by 683 to 7,503 -- by far the highest of any country.

The number of French deaths was up by 231 on Wednesday to more than 1,330, and metro and rail services in Paris were cut to a minimum.

Spain and Italy were joined by France and six more EU countries in urging Germany and the Netherlands to allow the issue of joint European bonds to cut borrowing costs and stabilise the eurozone economy.

The call is likely to fall on deaf ears when EU leaders talk on Thursday -- with northern members wary of pooling debt with big spenders -- but they will sign off on an "unprecedented" recovery plan.

At La Paz University Hospital in Madrid, nurse Guillen del Barrio sounded bereft as he related what happened overnight.

"It is really hard, we had feverish people for many hours in the waiting room," the 30-year-old told AFP.

"Many of my colleagues were crying because there were people who are dying alone, without seeing their family for the last time."

Coronavirus cases are also spreading in the Middle East, where Iran's death toll topped 2,000, and in Africa, where Mali declared its first case and several nations announced states of emergency.

In Japan, which has postponed this year's Olympic Games, Tokyo's governor urged residents to stay home this weekend, warning of a possible "explosion" of the coronavirus.

Jerusalem's Church of the Holy Sepulchre, believed by Christians to house Christ's tomb, was shut as Israel tightened movement restrictions.

The impact of the pandemic is also hitting European football, with leagues and tournaments cancelled, while the fate of the Wimbledon tennis tournament could be decided next week.

The economic damage of the virus -- and the lockdowns -- could also be devastating, with fears of a worldwide recession worse than the financial meltdown more than a decade ago.

But financial markets rose after US leaders reached agreement on a stimulus package worth roughly 10 percent of the US economy, an injection Senate Majority Leader Mitch McConnell said represented a "wartime level of investment."

Meanwhile, more than half of all Americans have been told to stay at home, including residents of the largest state, California.

The United States has at least 65,700 cases and 942 people have died.

Beijing, Jan 25: The death toll due to the novel coronavirus (2019-nCoV) outbreak in China has soared to 41, while the number of infected persons were 1,287, the National Health Commission said on Saturday.

The Commission said that 444 fresh cases were reported since Friday, with 237 patients in serious conditions, while 38 had been cured and discharged from hospitals, reports Efe news.

Health authorities have carried out check-ups on 15,197 people who have come into close contact with the infected persons. Nearly 14,000 of them continue to be monitored for symptoms.

The others cases outside of China were reported in France (two), Australia (one), Thailand (four including two cured), Japan (two including one cured), South Korea (two), the US (two), Vietnam (two), Singapore (three), Nepal (one), Hong Kong (five), Macao (two) and Taiwan (three).

The symptoms of the new coronavirus, provisionally designated by the World Health Organization as 2019-nCoV, are similar to those of cold but may be accompanied by fever and fatigue, dry cough and dyspnea (shortness of breath).

The WHO has so far to declared the outbreak as an international health emergency.

Strict measures were being carried out in China, which include complete suspension of transport in around a dozen cities in Hubei province and also cancelling Chinese New Year celebrations.

Traditional events at Lama Temple and Ditan Park in Beijing were cancelled due to the risk of spreading the virus, authorities reported Friday, while the famous Forbidden City has also been closed indefinitely.

Wuhan, the capital of Hubei, where the virus was first reported, has been on lockdown since Thursday to prevent further spread of the virus and the city's authorities have begun to build a "special hospital" with 1,000 beds for infected patients.

"Construction of the special hospital with a capacity of 1,000 beds for patients with #nCoV2019 has begun in Wuhan," official China Daily said on Twitter.

The hospital in Wuhan will be based on the model of a similar facility that was built in just seven days in Beijing to deal with SARS in 2003.

Washington/Seoul, Apr 26: A special train possibly belonging to North Korean leader Kim Jong Un was spotted this week at a resort town in the country, according to satellite images reviewed by a Washington-based North Korea monitoring project, amid conflicting reports about Mr. Kim's health and whereabouts.

The monitoring project, 38 North, said in its report on Saturday that the train was parked at the “leadership station” in Wonsan on April 21 and April 23. The station is reserved for the use of the Kim family, it said.

Though the group said it was probably Kim Jong Un's train, Reuters has not been able to confirm that independently, or whether he was in Wonsan.

“The train's presence does not prove the whereabouts of the North Korean leader or indicate anything about his health but it does lend weight to reports that Kim is staying at an elite area on the country's eastern coast,” the report said.

Speculation about Mr. Kim's health first arose due to his absence from the anniversary of the birthday of North Korea's founding father and Mr. Kim's grandfather, Kim Il Sung, on April 15.

North Korea's state media last reported on Mr. Kim's whereabouts when he presided over a meeting on April 11.

China has dispatched a team to North Korea including medical experts to advise on Kim Jong Un, according to three people familiar with the situation.

A third-generation hereditary leader who came to power after his father's death in 2011, Kim has no clear successor in a nuclear-armed country, which could present major international risk.

On Thursday, U.S. President Donald Trump downplayed reports that Mr. Kim was ill. “I think the report was incorrect,” Mr. Trump told reporters, but he declined to say if he had been in touch with North Korean officials.

Mr. Trump has met Mr. Kim three times in an attempt to persuade him to give up a nuclear weapons program that threatens the United States as well as its Asian neighbors. While talks have stalled, Mr. Trump has continued to hail Mr. Kim as a friend.

Reporting from inside North Korea is notoriously difficult because of tight controls on information.

A Trump administration official said continuing days of North Korean media silence on Mr. Kim's whereabouts had heightened concerns about his condition, and that information remained scant from a country U.S. intelligence has long regarded as a ”black box.”

The U.S. State Department did not immediately respond to questions about the situation on Saturday.

Daily NK, a Seoul-based website that reports on North Korea, cited one unnamed source in North Korea on Monday as saying that Kim had undergone medical treatment in the resort county of Hyangsan north of the capital Pyongyang.

It said that Mr. Kim was recovering after undergoing a cardiovascular procedure on April 12.

Since then, multiple South Korean media reports have cited unnamed sources this week saying that Mr. Kim might be staying in the Wonsan area.

On Friday, local news agency Newsis cited South Korean intelligence sources as reporting that a special train for Mr. Kim's use had been seen in Wonsan, while Mr. Kim's private plane remained in Pyongyang.

Newsis reported Mr. Kim may be sheltering from COVID-19, the respiratory disease caused by the novel coronavirus.

Mr. Kim, believed to be 36, has disappeared from coverage in North Korean state media before. In 2014, he vanished for more than a month and North Korean state TV later showed him walking with a limp.

Speculation about his health has been fanned by his heavy smoking, apparent weight gain since taking power and family history of cardiovascular problems.
