Canadian researchers developing DNA vaccine against COVID-19

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.

Apr 29: US President Donald Trump doubled down on China for failing to tame the coronavirus at its very origin, saying it has led to 184 countries "going through hell", as several American lawmakers demanded steps to reduce dependence on Beijing for manufacturing and minerals.

Trump has been publicly blaming China for the global spread of the "invisible enemy" and launched an investigation against it. He has also indicated that the US may be looking at "a lot more money" in damages from China than the USD 140 billion being sought by Germany from Beijing for the pandemic.

Leaders of the US, the UK and Germany believe that the deaths and the destruction of the global economy could have been avoided, had China shared the information about the virus in its early phases.

"It's in 184 countries, as you hear me say often. It's hard to believe. It's inconceivable," Trump told reporters at White House Tuesday. "It should have been stopped at the source, which was China. It should have been stopped very much at the source, but it wasn't. And now we have 184 countries going through hell.”

The virus, which originated in China's Wuhan city in mid-November, has killed more than two lakh people and infected over three million globally. The largest number of them are in the US: nearly 59,000 deaths and over one million infections.

The massive outbreak in the US has put Trump under increasing pressure from American lawmakers to decrease US dependence on Beijing and they have also sought compensation from China.

Senator Ted Cruz and his colleagues have urged Defence Secretary Mark Esper and Interior Secretary David Bernhardt to support the development of a fully domestic supply chain of rare earths and other minerals that are critical for manufacturing defence technologies and supporting national security.

“It is clear that our dependence on China for vital rare earths threatens our US manufacturing and defence-industrial base. As the October 2018 Defence Industrial Base Report states: ‘China represents a significant and growing risk to the supply of materials deemed strategic and critical to US national security.' [...] Ensuring a US supply of domestically sourced rare earths will reduce our vulnerability to supply disruptions that poses a grave risk to our military readiness," the Senators wrote.

The US is 100 percent import-dependent for rare earths as well as 13 other metals and minerals on the US Government Critical Minerals List and more than 75 percent import reliant for an additional 10 minerals.

Congressman Brian Mast on Tuesday introduced a legislation to hold China accountable for its "coronavirus deception". The resolution would empower the US to withhold payments on debts owed to China equal to the costs incurred by the US in response to COVID-19.

“China's total lack of transparency and mishandling of the coronavirus outbreak has cost tens of thousands of lives, millions of jobs and left untold economic destruction. Congress must hold China accountable for their cover-up and force them to pay back the taxpayer dollars that have been spent as a result,” Mast said.

Cruz, member of the Senate Foreign Relations Committee, announced his intention to introduce a legislation to cut off Hollywood studios from assistance they receive from the Department of Defence if those studios censor their films for screening in China.

This legislation is part of Sen. Cruz's comprehensive push to combat China's growing influence over what Americans see and hear, which includes legislation targeting information warfare from the Chinese Communist Party across higher education, sports, films, radio broadcasts, and more.

Indian-American Congressman Ami Bera and Congressman Ted S. Yoho, both members of the House Foreign Affairs Committee, will lead a bipartisan virtual Special Order to highlight the importance of US global leadership during the COVID-19 pandemic.

“If we abdicate our place as a leader in global health, there is another country eager to take the reins. China has not been subtle in asserting itself on global health issues, and often not for the benefit of other nations. China's recent coronavirus debacle should be evidence enough that their communist regime cannot be trusted to lead with accountability, transparency, or pragmatism, traits that are essential when fighting widespread disease,” Yoho said.

“As for how China would fare as a global health leader, look no further than the disastrous initial response by the WHO to coronavirus, one that was clearly influenced by Beijing. Information was slow-walked, warnings from nations like Taiwan were ignored at crucial turning points, and cooperation with outside health experts was spurned until it was too late. And it has resulted in the largest public health disaster the world has seen in over a century,” he said.

In an interview to Fox News, Senator Marco Rubio alleged that if China had acted when those warnings were being made, instead of silencing the people that were talking about it, they could have limited the spread.

“So there was no doubt that that was a deliberate decision made on their part. The one way to hold them accountable is to do what we should be doing anyway. That is moving the means of production to become less and less dependent upon them. What you're going to see after this pandemic is that more and more countries are going to prioritize their healthcare manufacturing capabilities and other industries,” he said.

Washington, Apr 24: President Donald Trump has favoured a phased reopening of the US economy, devastated by the coronavirus pandemic, which has claimed nearly 50,000 lives and infected over eight lakh people in the country.

More than 95 per cent of the country's 330 million people are under stay-at-home order as a result of the social mitigation measures, including social distancing, being enforced till May 1.

Trump on Thursday indicated that the stay-at-home order might be extended beyond May 1, but vehemently advocated the need to gradually open up the economy.

In the past few weeks, more than 26 million Americans have filed for unemployment benefits and the figure is soon likely to cross 40 million.

Both the World Bank and the International Monetary Fund (IMF) have projected a negative growth in the US in 2020.

To keep America gaining momentum, every citizen needs to maintain the vigilance, and we all understand that very well we've gone over it many, many times this includes practising good hygiene, maintaining social distance, and the voluntary use of face covering, Trump said.

Safe and phased reopening of our economy -- it's very exciting, but it does not mean that we are letting down our guard at all in any way; on the contrary, continued diligence is an essential part of our strategy to get our country back to work to take our country back, he told reporters at his daily White House news conference on coronavirus.

The data and facts on the ground suggest that the US is making great progress, he said.

In 23 states, new cases have declined. In the peak week, 40 per cent of the American counties have seen a rapid decline in new cases. As many as 46 states report a drop in patients showing coronavirus-like symptoms, he said.

Trump said the US is very close to finding a vaccine for COVID-19.

We are very close to testing... when testing starts it takes a period of time but we will get it done, he said.

According to Vice President Mike Pence, data continues to show promising signs of progress in the New York Metro area, New Jersey, Connecticut, Detroit and New Orleans. All appear to be passed their peak and we are seeing consistent declines in hospitalisation and cases in regions across the country, he said.

Jun 2: A new female billionaire has emerged from one of Asia's most-expensive breakups.

Du Weimin, the chairman of Shenzhen Kangtai Biological Products Co., transferred 161.3 million shares of the vaccine maker to his ex-wife, Yuan Liping, according to a May 29 filing, immediately catapulting her into the ranks of the world's richest.

The stock was worth $3.2 billion as of Monday's close.

Yuan, 49 this year, owns the shares directly, but signed an agreement delegating the voting rights to her ex-husband, the filing shows. The Canadian citizen, who resides in Shenzhen, served as a director of Kangtai between May 2011 and August 2018. She's now the vice general manager of subsidiary Beijing Minhai Biotechnology Co. Yuan holds a bachelor's degree in economics from Beijing's University of International Business and Economics.

Kangtai shares have more than doubled in the past year and have continued their ascent since February, when the company announced a plan to develop a vaccine to fight the coronavirus. They slipped for a second day Tuesday following news of the divorce terms, losing 3.1% as of 9:43 a.m. in Hong Kong and bringing the company's market value to $12.9 billion.

Du's net worth has now dropped to about $3.1 billion from $6.5 billion before the split, excluding his pledged shares.

The 56-year-old was born into a farming family in China's Jiangxi province. After studying chemistry in college, he began working in a clinic in 1987 and became a sales manager for a biotech company in 1995, according to the prospectus of Kangtai's 2017 initial public offering. In 2009, Kangtai acquired Minhai, the company Du founded in 2004, and he became the chairman of the combined entity.

China's rapidly growing economy has been an engine for the country's richest, and Du is not the only tycoon who's had to pay a steep price for a divorce. In 2012, Wu Yajun, at one point the nation's richest woman, transferred a stake worth about $2.3 billion to her ex-husband, Cai Kui, who co-founded developer Longfor Group Holdings Ltd. In 2016, tech billionaire Zhou Yahui gave $1.1 billion of shares in his online gaming company, Beijing Kunlun Tech Co., to ex-wife Li Qiong after a civil court settlement.

Sometimes, a goodbye can be time-consuming too. South Korean tycoon Chey Tae-won's wife filed a lawsuit in December asking for a 42.3% stake in SK Holdings Co. valued at $1.2 billion. That would make her the second-largest shareholder of the company should she win the case, which is still ongoing.

The most expensive divorce in history is that of Jeff and MacKenzie Bezos. The Amazon.com Inc. founder gave 4% of the online retailer to Mackenzie, who now has a $48 billion fortune and is the world's fourth-richest woman.
