Alwar lynching: Cops give clean chit to 6 miscreants named by victim Pehlu Khan

New Delhi, May 30: An Air India flight from Delhi to Moscow on Saturday had to return midway after the airline's ground team found out that one of the pilots had tested positive for novel coronavirus, officials said.

"When the A320 plane, which did not have any passengers as it was heading to Moscow to bring back stranded Indians under Vande Bharat Mission, had reached Uzbekistan's airspace, our team on ground realised that one of the pilots had tested COVID-positive," senior Air India officials said.

"The flight was immediately asked to return. It came back to Delhi at around 12.30 pm on Saturday," the officials said. The crew has been quarantined. Another plane would be sent to Moscow to bring back the stranded Indians, according to the officials.

New Delhi, Jul 6: The Indian Academy of Sciences, a Bengaluru-based body of scientists, has said the Indian Council for Medical Research's (ICMR) target to launch a coronavirus vaccine by August 15 is "unfeasible" and "unrealistic".

The IASc said while there is an unquestioned urgent need, vaccine development for use in humans requires scientifically executed clinical trials in a phased manner.

While administrative approvals can be expedited, the "scientific processes of experimentation and data collection have a natural time span that cannot be hastened without compromising standards of scientific rigour", the IASc said in a statement.

In its statement, the IASc referred to the ICMR's letter which states that "it is envisaged to launch the vaccine for public health use latest by 15th August 2020 after completion of all clinical trials".

The ICMR and Bharat Biotech India Limited, a private pharmaceutical company, are jointly developing the vaccine against the novel coronavirus -- SARS-CoV-2.

The IASc welcomes the exciting development of a candidate vaccine and wishes that the vaccine is quickly made available for public use, the statement said.

"However, as a body of scientists including many who are engaged in vaccine development IASc strongly believes that the announced timeline is unfeasible. This timeline has raised unrealistic hope and expectations in the minds of our citizens," it said.

Aiming to launch an indigenous COVID-19 vaccine by August 15, the ICMR had written to select medical institutions and hospitals to fast-track clinical trial approvals for the vaccine candidate, COVAXIN.

Experts have also cautioned against rushing the process for developing a COVID-19 vaccine and stressed that it is not in accordance with the globally accepted norms to fast-track vaccine development for diseases of pandemic potential.

The IASc said trials for a vaccine involve evaluation of safety (Phase 1 trial), efficacy and side effects at different dose levels (Phase 2 trial), and confirmation of safety and efficacy in thousands of healthy people (Phase 3 trial) before its release for public use.

Clinical trials for a candidate vaccine require participation of healthy human volunteers. Therefore, many ethical and regulatory approvals need to be obtained prior to the initiation of the trials, it added.

The IASc said the immune responses usually take several weeks to develop and relevant data should not be collected earlier.

"Moreover, data collected in one phase must be adequately analysed before the next phase can be initiated. If the data of any phase are unacceptable then the clinical trial is required to be immediately aborted," it said.

For example, if the data collected from Phase 1 of the clinical trial show that the vaccine is not adequately safe, then Phase 2 cannot be initiated and the candidate vaccine must be discarded.

For these reasons, the Indian Academy of Sciences believes that the announced timeline is "unreasonable and without precedent", the statement said.

"The Academy strongly believes that any hasty solution that may compromise rigorous scientific processes and standards will likely have long-term adverse impacts of unforeseen magnitude on citizens of India," it said.

New Delhi, Jan 31: The Supreme Court Friday dismissed the plea filed by one of the four death row convicts in the Nirbhaya gang-rape and murder case, Pawan Gupta, seeking review of its order rejecting his juvenility claim.

The review plea filed earlier in the day was taken up for consideration in-chamber by a bench comprising Justices R Banumathi, Ashok Bhushan and A S Bopanna. 

On January 20, the apex court had rejected the plea by Pawan who had challenged the Delhi High Court's order dismissing his juvenility claim.

Advocate A P Singh, who is representing Pawan in the case, said he filed a petition on his behalf seeking review of the top court's January 20 order on Friday.

While dismissing the plea, the top court had said there was no ground to interfere with the high court order that rejected Pawan's plea and his claim was rightly rejected by the trial court as also the high court.

It had said the matter was raised earlier in the review petition before the apex court which rejected plea of juvenility taken by Pawan and another co-accused Vinay Kumar Sharma and that order has attained finality.

Singh had argued that as per his school leaving certificate, he was a minor at the time of the offence and none of the courts, including trial court and high court, ever considered his documents.

Solicitor General Tushar Mehta, appearing for the Delhi Police, had said Pawan's claim of juvenility was considered at each and every judicial forum and it will be a travesty of justice if the convict is allowed to raise the claim of juvenility repeatedly and at this point of time.

The trial court on January 17 issued black warrants for the second time for the execution of all the four convicts in the case -- Mukesh Kumar Singh (32), Pawan (25), Vinay (26) and Akshay (31) -- in Tihar jail at 6 am on February 1. Earlier, on January 7, the court had fixed January 22 as the hanging date.

As of now, only Mukesh has exhausted all his legal remedies including the clemency plea which was dismissed by President Ram Nath Kovind on January 17 and the appeal against the rejection was thrown out by the Supreme Court on January 29.

Convict Akshay's curative petition was dismissed by the top court on January 30. Another death row convict Vinay moved mercy plea before President on January 29, which is pending.

Singh has also approached the trial court seeking stay on the execution scheduled on February 1, saying the legal remedies of some of the convicts are yet to be availed.

A 23-year-old paramedic student, referred to as Nirbhaya, was gang-raped and brutally assaulted on the intervening night of December 16-17, 2012, in a moving bus in south Delhi by six people before she was thrown out on the road.
