ABVP, AISA activists clash over blocking of Umar Khalid’s visit to Ramjas college

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.

Jaipur, Mar 11: A 85-year-old man in Jaipur, who had returned from Dubai on February 28, has tested positive for coronavirus, a state government official said on Wednesday.

The man has been kept in isolation at the SMS Hospital here.

“The man came to the hospital on Monday with symptoms of the virus. After the first test, his wife and son too have been kept in isolation at the hospital. The two, however, do not have coronavirus affliction symptoms,” Singh said.

A total of 235 people who came in contact with the octogenarian and his family have already been traced and are being monitored, he said.

New Delhi, Feb 11: Delhi BJP chief Manoj Tiwari on Tuesday said the party will review why it failed to meet its own expectations in the Assembly polls and saw a moral victory in the fact that the party's vote share has increased since 2015.

"Delhi must have given mandate after careful thinking. Our vote percentage has increased from 32 per cent to around 38 per cent. Delhi did not reject us and the increase (in vote share) is a good sign for us," he told reporters.

He said the BJP hopes that there would be less blame game and more work in the national capital and congratulated Arvind Kejriwal on his party's victory in the polls.

After winning the Patparganj seat, AAP senior leader Manish Sisodia accused the BJP of indulging in the politics of hate.

"We indulge in politics of development not politics of hate. We're against the roadblock in Shaheen Bagh as we were earlier," he said.
