Imran Khan now marries his spiritual guide Bushra Maneka

New Delhi, Mar 21: A couple was deboarded from a Delhi-bound Rajdhani train on Saturday after co-passengers observed a home quarantine seal on the husband's hand, the Railways said Saturday.

Officials said the Delhi-based couple boarded the Bangalore City-New Delhi Rajdhani at Secunderabad on Saturday morning.

When the train reached Kazipet in Telangana at 9:45 am, a co-passenger noticed the quarantine mark authorities are putting on suspected coronavirus cases —on the husband's hand when he was washing his hands. Other co-passengers then informed the TTE onboard.

The train was briefly detained and the couple was taken to a hospital. The coach was completely sanitised in Kazipet and was locked, officials said.

The air conditioning was also switched off.

The train left for its destination at 11.30 am.

People fleeing quarantine has been a common problem reported from different parts of the country.

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.

New Delhi, Feb 5: Taking on Delhi Chief Minister Arvind Kejriwal after Shaheen Bagh shooter Kapil Baisala was identified as an AAP worker by police, BJP chief J P Nadda on Tuesday said it exposed the party and Kejriwal who were playing with the country's security.

The Aam Aadmi Party hit back, questioning the police investigation.

In a series of tweets, Nadda said people of the country and Delhi today have seen the "dirty face" of AAP.

"For political longing, Kejriwal and his people even sold the security of the country. Earlier, Kejriwal used to insult the Army and advocate terrorists, but today relations with those who carry out their terrorist activities came to light," he said.

Nadda said he wanted to make it clear to Kejriwal that this country is bigger than any election, any government, and "this nation will not forgive those who play with its security. Kejriwal and his entire team have been exposed. The people of Delhi will give a befitting reply".

He claimed the entire country has seen "photos of Imam Hussain, the MLA and former minister of the Delhi government, with a radical terrorist organisation, PFI".

Days before Delhi goes to polls, police claimed that Baisala is a member of the Aam Aadmi Party. They said Baisala joined the party in early 2019 along with his father.

Police said it had photos of Baisala purportedly joining AAP along with his father Gaje Singh last year.

AAP's Rajya Sabha MP Sanjay Singh alleged that photos which were part of investigation were leaked to the BJP. He also said the party will approach the Election Commission to raise this issue, which has cropped up four days before the polling date.

"On whose instance, the police is giving statement? How did the photos which were part of the investigation reach the BJP? Before the news came out, Manoj Tiwari in the morning stated that the accused was from AAP. How did Manoj Tiwari get this news," Singh questioned in a press conference.

Union minister and BJP's in-charge for the Delhi polls, Prakash Javadekar, in a press conference alleged that "their (AAP's) designs are very clear from the beginning and they are trying every trick".

The whole conspiracy of AAP is to "divide society, cause fear in a community and create a vote bank," he charged.

Javadekar also claimed that photos of Baisala were recovered by police from his mobile phone although they were erased.

He also claimed that Baisala and his father were welcomed by Sanjay Singh at their joining of AAP.

"This proves AAP misleads youth and pushes them on the wrong path. AAP's strategy is to divide two communities, they want to instigate riots in Delhi," Javadekar alleged.

He further alleged that AAP leader Sanjay Singh had said violence would take place in Delhi. Their "conspiracy has been exposed by Delhi Police," he claimed.

"We condemn this politics of AAP," he said.

Javadekar also claimed this was "not an isolated incident" as AAP member Amanatullah Khan made a "very provocative speech" and the party supported Shaheen Bagh and did not give permission for the prosecution of members of the "tukde-tukde gang".

He hinted the BJP could approach the Election Commission against AAP over the issue.
