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.

Washington, Feb 25: Democratic presidential front-runner Senator Bernie Sanders on Monday slammed President Donald Trump for selling weapons to India, saying that the US should instead partner with New Delhi to fight climate change to save the planet.

Sanders, who has won the Nevada and New Hampshire primaries and tied in Iowa, made the comments after Trump, who is on a two-day visit to India, on Monday announced that the US will sign defence trade deals worth USD 3 billion with India.

In an address at a massive "Namaste Trump" rally at Motera stadium in Ahmedabad, Trump announced that deals to sell state-of-the-art military helicopters and other equipment worth over USD 3 billion will be sealed with India on Tuesday.

“Instead of selling USD 3 billion in weapons to enrich Raytheon, Boeing and Lockheed, the United States should be partnering with India to fight climate change,” Sanders said in a tweet, the first by a Democratic presidential candidate on Trump's India visit.

“We can work together to cut air pollution, create good renewable energy jobs, and save our planet,” he said.

However, a former White House official defended the US' decision to sell arms and weapons to India.

“I'm proud of my service in the White House, in which we poured enormous energy into deepening climate and green tech cooperation w/ India... and also advancing security cooperation and defense sales. I'd like to think both can be part of a strong, values-based partnership,” Joshua White said.

According to the US State Department, India plays a vital role in the US vision for a free and open Indo-Pacific.

In 2016, the US designated India as a Major Defence Partner. Commensurate with this designation, India in 2018 was granted Strategic Trade Authorization tier 1 status, which allows New Delhi to receive license-free access to a wide range of military and dual-use technologies that are regulated by the Department of Commerce.

Bilateral defence trade with India in a little over a decade has increased from near zero in 2008 to USD20 billion.

Among some of the key foreign military sales notified to Congress include MH-60R Seahawk helicopters (USD2.6 billion), Apache helicopters (USD2.3 billion), P-8I maritime patrol aircraft (USD3 billion), and M777 howitzers (USD737 million).

India was the first non-treaty partner to be offered a Missile Technology Control Regime Category-1 Unmanned Aerial System – the Sea Guardian UAS manufactured by General Atomics.

The State Department is also advocating for the Lockheed Martin F-21 and Boeing F/A-18 – two state of the art fighter aircraft that India is currently evaluating.

These platforms provide critical opportunities to enhance India's military capabilities and protect shared security interests in the Indo-Pacific region, it argued.

The top categories of DCS to India include aircraft, electronics and gas turbine engines.

As of Saturday morning, the overall number of infections increased to 1,698,416, while the tally of those who recovered from the deadly disease stood at 376,677, according to the varsity's Center for Systems Science and Engineering (CSSE).

In terms of cases, the US had the highest in the world at 501,301, followed by Spain 158,273, Italy 147,577 and France 125,931.

Italy accounted for the highest death toll at 18,849, with the US in the second place with 18,769 fatalities.

Other countries with more than 10,000 deaths include Spain (16,081) and France (13,197).

Geneva, Jul 4: The World Health Organization has updated its account of the early stages of the COVID crisis to say it was alerted by its own office in China, and not by China itself, to the first pneumonia cases in Wuhan.

The UN health body has been accused by US President Donald Trump of failing to provide the information needed to stem the pandemic and of being complacent towards Beijing, charges it denies.

On April 9, WHO published an initial timeline of its communications, partly in response to criticism of its early response to the outbreak that has now claimed more than 521,000 lives worldwide.

In that chronology, WHO had said only that the Wuhan municipal health commission in the province of Hubei had on December 31 reported cases of pneumonia. The UN health agency did not however specify who had notified it.

WHO director Tedros Adhanom Ghebreyesus told a press conference on April 20 the first report had come from China, without specifying whether the report had been sent by Chinese authorities or another source.

But a new chronology, published this week by the Geneva-based institution, offers a more detailed version of events.

It indicates that it was the WHO office in China that on December 31 notified its regional point of contact of a case of "viral pneumonia" after having found a declaration for the media on a Wuhan health commission website on the issue.

The same day, WHO's epidemic information service picked up another news report transmitted by the international epidemiological surveillance network ProMed -- based in the United States -- about the same group of cases of pneumonia from unknown causes in Wuhan.

After which, WHO asked the Chinese authorities on two occasions, on January 1 and January 2, for information about these cases, which they provided on January 3.

WHO emergencies director Michael Ryan told a press conference on Friday that countries have 24-48 hours to officially verify an event and provide the agency with additional information about the nature or cause of an event.

Ryan added that the Chinese authorities immediately contacted WHO's as soon as the agency asked to verify the report.

US President Donald Trump has announced that his country, the main financial contributor to WHO, will cut its bridges with the institution, which he accuses of being too close to China and of having poorly managed the pandemic.

The WHO denies any complacency toward China.
