Delhi elections 2020: Arvind Kejriwal's total assets worth Rs 3.4 crore, an increase of Rs 1.3 crore from 2015

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, Apr 3: Prime Minister Narendra Modi on Friday urged people to gather together for a unique exercise on April 5 at 9 pm to show they were together in the fight against coronavirus.

"On this Sunday, April 5, we will challenge the darkness of coronavirus threat together. On April 5, at 9 pm, I need your 9 minutes. At 9 pm, turn off all the lights in your houses and light a Diya, candle, torch or flashlight for 9 minutes at your doors, or balcony," Modi said.

The Prime Minister further said that this will send out a message that nobody among the 130 crore Indians is alone in this fight against the deadly infection.

"I have one more prayer to all of you, nobody has to gather at any place during this event. Everyone will light a Diya only at their doors, windows or balconies. The Laxman Rekha of social distancing must be followed," Modi said.
Earlier, the Prime Minister had said that 130 crore Indians are together in this fight against coronavirus and praised the countrymen for following the lockdown.

"Today when crores of people are inside homes, then some of us may think how will they fight this battle against COVID-19 alone. Such questions might come up in your mind? But please remember, none of us is alone. The strength of 130 crores of Indians is with each one of us," he said.

He also expressed gratitude towards countrymen for participating in 'Janata curfew' on March 22 and said it has become "an example for all countries" today as they are following it.

In his address to the nation on March 24, the Prime Minister had announced a 21-day lockdown in the country to contain the spread of novel coronavirus, which has infected over 2,000 people in the country.

During the last "Mann Ki Baat" on COVID-19 related issue, the Prime Minister had apologised to the countrymen for taking the tough decision of enforcing complete lockdown in the nation. "My conscience says you will forgive me," he had said.
