Malaysia bigwig stalling Aircel-Maxis case probe, CBI tells Supreme Court

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.

Hyderabad, Feb 26: Hyderabad Police on Tuesday registered a case against well-known poet Imran Pratapgarhi for his statement asking why there was "no Shaheen Bagh in Hyderabad".

According to Charminar Police, the complaint was registered by Sub-Inspector S Guruswamy, who was on duty at the QQ Stadium on February 24 where an Ehtaji Mishaira (Poetry Program) against the Citizenship Amendment Act, National Register Commission and National Population Register was held.

Permission for the said event was granted by Hyderabad Additional Commissioner of Police to the program organisers with certain guidelines including that poetry program should be held on February 24 from 6 pm to 9 pm, and no speaker should give provocative speeches in the program.

However, police said that the program was started by the organisers at 6 pm and continued till 9:48 pm even after police officers asked them to end the event by 9 pm. The program was attended by around 3,000 members at QQ stadium.

According to police, while addressing the meeting Pratapgarhi said: "Mujhe hairath hai us Hyderabad mein koi Shaheen Bagh kyu nahi hai (I am surprised why there is no Shaheen Bagh in Hyderabad)", which is "provocative" and may cause fear to any section of the public.

In this regard, a case has been registered against organisers for disobeying public servants' orders and the poet has been booked for delivering provocative statements under the relevant sections of the Indian Penal Code.

Further investigation is underway.

Meanwhile, Congress leader Mohammed Ali Shabbir took to Twitter to condemn the police action.

"Hyderabad Police booked a case against poet Imran Pratapgarhi for expressing surprise on why there is no Shaheen Bagh in Hyderabad. For police, this sentence is provocative. Is Shaheen Bagh not a part of India?," Shabbir tweeted.

"Shame on TRS Government and Hyderabad Police for targeting a poet for no-fault," he added.

Mathura, Mar 2: Union Minister of state Sadhvi Niranjan Jyoti on Sunday said after the Citizenship (Amendment) Act (CAA), the Centre might bring a population control law.
