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.

Washington, Jan 12: The US State Department has described the recent visit of envoys of 15 countries to Jammu and Kashmir as an "important step" but expressed concern over the continued detention of political leaders and restrictions on internet in the region.

Alice Wells, the Acting Assistant Secretary of State for South Asia, tweeted on Saturday that she was "closely following" the visit of the envoys to Kashmir, describing it an "important step".

Wells, who will be visiting India this week, added: "We remain concerned by detention of political leaders and residents and Internet restrictions. We look forward to a return to normalcy."

The group of diplomats made a two-day visit to the Union Territory on Thursday and Friday to see the conditions thereafter Jammu and Kashmir's special constitutional status was removed last August.

While some US politicians and media have criticised the action by Prime Minister Narendra Modi's government, the US has officially appeared to support the abrogation of the Constitution's Article 370 on the special status.

Last October, Wells told the House of Representatives Subcommittee on Asia and the Pacific that the State Department supported the objectives behind it, while not directly mentioning the abrogation.

"The Indian government has argued that its decision on Article 370 was driven by a desire to increase economic development, reduce corruption, and uniformly apply all national laws in Jammu and Kashmir, particularly in regard to women and minorities.

"While we support these objectives, the Department remains concerned about the situation in the Kashmir Valley, where daily life for the nearly eight million residents has been severely impacted since August 5," she had said.

Washington has banked on India's democratic institutions - the judiciary and public debates - being able to steer the country.

Bearing this out, the Supreme Court last week ordered the government to review its decision to shut down the internet in Kashmir, which it declared was a fundamental right, thus taking a step to address Wells's concern.

Seoul, Jul 26: North Korean authorities have imposed a lockdown on the border city of Kaesong after discovering what they called the country's first suspected case of the novel coronavirus, state media reported Sunday.

Leader Kim Jong Un convened an emergency politburo meeting on Saturday to implement a "maximum emergency system and issue a top-class alert" to contain the virus, official news agency KCNA said.

If confirmed, it would be the first officially recognised COVID-19 case in the North where medical infrastructure is seen as woefully inadequate for dealing with any epidemic.

KCNA said a defector who had left for the South three years ago returned on July 19 after "illegally crossing" the heavily fortified border dividing the countries.

But there have been no reports in the South of anyone leaving through what is one of the world's most secure borders, replete with minefields and guard posts.

Pyongyang has previously insisted not a single case of the coronavirus had been seen in the North despite the illness having swept the globe, and the country's borders remain closed.

The patient was found in Kaesong City, which borders the South, and "was put under strict quarantine", as would anybody who had come in close contact, state media said.

It was a "dangerous situation... that may lead to a deadly and destructive disaster", the media outlet added.

Kim was quoted as saying "the vicious virus could be said to have entered the country", and officials on Friday took the "preemptive measure of totally blocking Kaesong City".

The nuclear-armed North closed its borders in late January as the virus spread in neighbouring China and imposed tough restrictions that put thousands of its people into isolation, but analysts say the North is unlikely to have avoided the contagion.

South Korea is currently recording around 40 to 60 cases a day.

Earlier this month Kim warned against any "hasty" relaxation of anti-coronavirus measures, indicating the country will keep its borders closed for the foreseeable future.
