New Delhi, May 25: Mahindra Group Chairman Anand Mahindra on Monday said lockdown extensions are not just economically disastrous but also create another medical crisis.

While acknowledging that choices are not easy for policymakers, he said a lockdown extension will not help.

"Lockdown extensions aren't just economically disastrous, as I had tweeted earlier, but also create another medical crisis," Mahindra said in a tweet.

He was referring to an article that highlighted "the dangerous psychological effects of lockdowns & the huge risk of neglecting non-COVID patients".

Mahindra, who had earlier proposed a comprehensive lifting after 49 days of lockdown, further said, "The choices aren't easy for policy makers but a lockdown extension won't help".

He said, "The numbers (coronavirus cases) will continue to rise & the focus must be on rapid expansion of field hospital beds with oxygen lines".

He further said, "The army has enormous expertise in this".

On March 22, before the government announced nationwide lockdown, Mahindra had proposed such a move expressing concerns over reports that India was likely to have already reached stage 3 of coronavirus transmission.

New Delhi, Mar 10: A military transport aircraft of the Indian Air Force (IAF) brought back 58 Indians from coronavirus-hit Iran on Tuesday, official said.

The aircraft, a C-17 Globemaster, was sent to Tehran on Monday evening.

About 2,000 Indians are living in Iran, a country that has witnessed increasing numbers of coronavirus cases in the last few days.

"The IAF aircraft has landed. Mission completed. On to the next," External Affairs Minister S Jaishankar tweeted.

In an earlier tweet, he said, "First batch of 58 Indian pilgrims being brought back from Iran. IAF C-17 taken off from Tehran and expected to land soon in Hindon."

"Thanks to the efforts of our Embassy @India_in_Iran and Indian medical team there, operating under challenging conditions. Thank you @IAF_MCC. Appreciate cooperation of Iranian authorities. We are working on the return of other Indians stranded there (sic)," Jaishankar added.

The aircraft landed at Hindon airbase in Ghaziabad, from where the passengers were take to a medical facility.

According to latest reports, 237 people have died of novel coronavirus in Iran while the number of positive cases stands at around 7,000.

It is the second such evacuation by the C-17 Globemaster in the last two weeks.

On February 27, 76 Indians and 36 foreign nationals were brought back from the Chinese city of Wuhan by the aircraft of the Indian Air Force.

The C-17 Globemaster is the largest military aircraft in the IAF's inventory. The plane can carry large combat equipment, troops and humanitarian aid across long distances in all weather conditions.

Four days ago, a Mahan airline plane brought swab samples of 300 Indians from Iran to India.

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.
