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.

Paris, Apr 17: The number of coronavirus-related deaths in France has increased by 753 to 17,920 over the past 24 hours, with the total case count now standing at 108,847, Jerome Salomon, the head of the state health agency, said on Thursday.

On Wednesday, the country reported a total of 106,206 cases, including a record 1,438 new fatalities. Salomon specified that it was not the daily death toll, as the data had been compiled over the last three-day weekend.

"The total number of victims since March 1 is 17,920," Salomon said at a briefing on Thursday.
He noted that 11,060 of them had died in hospitals, and 6,860 others in social and medical-social facilities.

President Emmanuel Macron on Monday extended nationwide movement restrictions, which had been introduced due to the epidemic, until May 11. Afterwards, the country is set to gradually reopen kindergartens, schools and universities.

New Delhi, Feb 21: Global terror financing watchdog FATF on Friday decided continuation of Pakistan in the "Grey List" and warned the country that stern action will be taken if it fails to check flow of money to terror groups like the LeT and the JeM, sources said.

The decision has been taken at the Financial Action Task Force's plenary in Paris.

The FATF decided to continue Pakistani in the "Grey List". The FATF also warned Pakistan that if it doesn't complete a full action plan by June, it could lead to consequences on its businesses, a source said.

New Delhi, Mar 16: Due to the coronavirus pandemic, most airlines in the world will be bankrupt by the end of May and only a coordinated government and industry action right now can avoid the catastrophe, said global aviation consultancy firm CAPA in a note on Monday.

"As the impact of the coronavirus and multiple government travel reactions sweep through our world, many airlines have probably already been driven into technical bankruptcy, or are at least substantially in breach of debt covenants," it stated.

Across the world, airlines have announced drastic reduction in their operations in the wake of the coronavirus outbreak. For example, Atlanta-based Delta Air Lines stated on Sunday that it would be grounding 300 aircraft in its fleet and reduce flights by 40 per cent.

The US has suspended all tourist visas for people belonging to the European Union, the UK and Ireland. Similarly, the Indian government has suspended all tourist visas and e-visas granted on or before March 11.

CAPA, in its note on Monday, said, "By the end of May-2020, most airlines in the world will be bankrupt. Coordinated government and industry action is needed - now - if catastrophe is to be avoided."

Cash reserves are running down quickly as fleets are grounded and "what flights there are operate much less than half full", it added.

"Forward bookings are far outweighed by cancellations and each time there is a new government recommendation it is to discourage flying. Demand is drying up in ways that are completely unprecedented. Normality is not yet on the horizon," it said.

India's largest airline IndiGo -- which has around 260 planes in its fleet -- said on Thursday that it has seen a decline of 15-20 per cent in daily bookings in the last few days.

The low-cost carrier had stated that it expects its quarterly earnings to be materially impacted due to such decline.

CAPA said the failure to coordinate the future will result in protectionism and much less competition.

"The alternative does not bear thinking about. An unstructured and nationalistic outcome will not be survival of the fittest.

"It will mostly consist of airlines that are the biggest and the best-supported by their governments. The system will reek of nationalism. And it will not serve the needs of the 21st century world. That is not a prospect that any responsible government should be prepared to contemplate," the consultancy firm said.
