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, Apr 20: The US wants to send a team of experts to China to investigate coronavirus, President Donald Trump has said, a day after he warned Beijing of "consequences" if it was knowingly responsible for the spread of COVID-19 which has killed more than 165,000 people globally, including over 41,000 in America.

Describing the coronavirus as a plague, Trump, during his White House news conference on Sunday, said that he is not happy with China where the pandemic emerged in December last year in the central Chinese city of Wuhan.

“We spoke to them (Chinese) a long time ago about going in. We want to go in. We want to see what's going on. And we weren't exactly invited, I can tell you that,” the President told reporters.

“I was very happy with the (trade) deal (with China), very happy with everything and then we found out about the plague and since we found out about that I'm not happy,” he said.

The US has launched an investigation into whether the deadly virus "escaped" from the Wuhan Institute of Virology.

He has repeatedly expressed disappointment over China's handling of the coronavirus disease, alleged non-transparency and initial non-cooperation from Beijing with Washington on dealing with the crisis.

“Based on an investigation, we are going to find out,” Trump told reporters.

A day earlier, he warned China that it should face consequences if it was "knowingly responsible" for the spread of the novel coronavirus, upping the ante on Beijing over its handling of the COVID-19 pandemic.

“If they (China) were knowingly responsible… then there should be consequences. You're talking about, you know, potentially lives like nobody's seen since 1917,” Trump said on Saturday.

The opposition Democratic Party said that Trump has falsely claimed he acted early by restricting travel from China when it was little too late and he continued to downplay the virus throughout February.

The number of COVID-19 deaths in the US crossed 41,000 and the total infections were more than 764,000 so far.

New York, the epicentre of the deadly COVID-19 in the US, has 2,42,000 cases and over 17,600 fatalities so far. It has registered a 50-percent decline in new cases over an eight-day period.

The novel virus, which emerged in China in December last year, has killed over 160,000 and infected more than 2.3 million people worldwide.

Islamabad, Feb 26: Islamabad on Tuesday declared former Prime Minister Nawaz Sharif an absconder while simultaneously denying extending bail to him.

The federal cabinet presided over by Prime Minister Imran Khan, cited that Sharif failed to provide required medical reports and has violated the bail terms.

The government has also decided to freeze gas and electricity tariffs for the next four months, The Dawn reported.

"After Nawaz Sharif failed to submit his medical report of any hospital in London, the medical board rejected a medical certificate sent by him and [the government] declared him an absconder. From today, Nawaz Sharif is an absconder according to the law of land and if he does not return to the country he will be declared a proclaimed offender," said Dr Firdous Ashiq Awan, Special Assistant to the Prime Minister on Information, in a press conference.

She further asserted that the Punjab government, which was authorized by the Islamabad High Court (IHC) to decide Sharif's case on medical grounds, had written several letters asking him to submit his medical report from any hospital in London. However, he failed to do so and only sent a certificate that was not accepted by the medical board.

"If he (Nawaz Sharif) is seriously ill then why a comprehensive medical report is not being submitted to the medical board," Firdous added.

Further, she said that the office of the opposition leader was also waiting for his younger brother and Leader of the Opposition in the National Assembly Shahbaz Sharif, who was also staying in London for 'no reason'.

"He is getting a monthly salary and enjoying luxurious offices and other perks and privileges but not performing his duties required by his office and the people. Shahbaz Sahib, return to the country and justify your salary and other benefits being given from taxpayers' money," Firdous added.

On October 29 last year, the IHC granted bail for eight weeks to Sharif, who was convicted and disqualified in corruption cases, on medical grounds.

Sharif left Pakistan for London along with Shahbaz on November 19, 2019, for his medical treatments there.

Sheikhupura, May 26: Younus, the brother-in-law of Asia Bibi, a Christian woman convicted of blasphemy by a Pakistani court, was killed in Sheikhupura city of Punjab province in Pakistan on Monday.

According to the FIR, Younus had gone to his farms on May 24 and did not return home at night. His body with throat slit was traced in the farm the following morning.

It is believed that, hailing from minority Christian community, Younus was killed in a rivalry.

This is not the first time that somebody associated with Asia Bibi has been murdered in cold blood.

In 2011, Salman Taseer, the influential governor of Punjab was assassinated after he made headlines by appealing for the pardon of Asia Bibi, who had been sentenced to death for allegedly insulting Prophet Muhammad.

A month after Taseer was killed, Religious Minorities Minister Shahbaz Bhatti, a Christian who spoke out against the laws, was shot dead in Islamabad, underlining the threat faced by critics of the law.

Asia Bibi is now living in exile after the Supreme Court of Pakistan acquitted her based on insufficient evidence in October 2018.

Recounting the hellish conditions of eight years spent on death row on blasphemy charges but also the pain of exile, Asia Bibi recently broke her silence to give her first personal insight into an ordeal that caused international outrage.

French journalist Anne-Isabelle Tollet, who has co-written a book about her, was once based in the country where she led a support campaign for her."You already know my story through the media," she said in the book.

"But you are far from understanding my daily life in prison or my new life," she said. "I became a prisoner of fanaticism," she said. In prison, "tears were the only companions in the cell".

She described the horrendous conditions in squalid jails in Pakistan where she was kept chained and jeered at by other detainees.

Pakistan's blasphemy laws carry a potential death sentence for anyone who insults Islam. Critics say they have been used to persecute minority faiths and unfairly target minorities.

Pakistan's Prime Minister Imran Khan defended the country's strict blasphemy laws during his election campaigns. The status quo is still in place.

No government in Pakistan was ready to make changed to the blasphemy law due to fears of a backlash.
