6 killed, over 20 missing after dam in Ratnagiri breached

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, Dec 24: The Delhi Police said that a head constable was killed during clashes over the Citizenship Amendment Act (CAA) in northeast Delhi today.

Deputy Commissioner of Police, Shahdara, Amit Sharma was also injured during clashes, a senior official said. Sharma suffered injuries to his head and hand. He was hospitalised and is doing fine, the official added.

Tension escalated in northeast Delhi with protesters torching at least two houses and a fire tender in the Jaffrabad and Maujpur areas, where pro and anti-CAA groups clashed for the second consecutive day on Monday and hurled stones at each other.

Violence was also reported from the Chandbagh area in Jaffrabad.

Police fired tear gas shells and also resorted to lathicharge to disperse the protesters.

According to officials, a fire tender was damaged by the protesters after it responded to a fire call in the area.

The Delhi Metro closed entry and exit at the Jaffrabad and Maujpur-Babarpur stations as an uneasy calm prevailed in the area.

"Entry & exit of Jaffrabad and Maujpur-Babarpur are closed. Trains will not be halting at these stations," the Delhi Metro Rail Corporation (DMRC) said in a tweet.

Entry and exit were closed at the Jaffrabad metro station for over 24 hours.

Clashes broke out on Sunday evening between pro and anti-CAA groups near Jaffrabad after a large number of people protesting against the Citizenship (Amendment) Act (CAA) blocked a road, while similar sit-ins were launched in several other parts of the national capital.

Delhi chief minister Arvind Kejriwal has urged lieutenant governor of Delhi and the Union home minister to restore order.

Nobody should be allowed to orchestrate violence, he said.

Delhi Lt Governor Anil Baijal instructed the police commissioner to maintain law and order in the national capital in the wake of violence.

"Instructed @DelhiPolice and @CPDelhi to ensure that law and order is maintained in North East Delhi. The situation is being closely monitored. I urge everyone to exercise restraint for maintenance of peace and harmony," Baijal tweeted.

Delhi minister and Babarpur MLA Gopal Rai on Monday urged the people in the area to maintain peace, saying some people were purposely trying to disturb the atmosphere.

"With folded hands, I request people in Babarpur Assembly to maintain peace. Some people are purposely trying to spoil the atmosphere. I have spoken to Delhi LG and he has assured me that more policemen will be deployed to bring the situation under control," Rai said in a tweet.

Mumbai, Feb 3: Maharashtra Chief Minister Uddhav Thackeray, whose party severed ties with the BJP after the state elections, on Monday said that if somebody breaks a promise, "pain and anger is obvious".

"No, I did not get any shock," Thackeray said in an interview with Shiv Sena mouthpiece Saamana while talking about forming an alliance with NCP and Congress, and becoming the Maharashtra Chief Minister.

"I am a son of Shiv Sena Pramukh (Balasaheb Thackeray), several people tried to give a shock to me but they didn't succeed. This is a field where you have to accept in the beginning that there will be a bit pushing and pulling," Thackeray said.

He added that accepting the Chief Minister's post was not a shock for him and neither was it his "dream at any point of time".

"But I can say one thing for sure that I had decided to go to any level to fulfil the promise which I made to Balasaheb Thackeray. I want to further clear it that me becoming Chief Minister is not the fulfilling of the promise made to Shiv Sena Pramukh but it's just a step towards that. I will fulfil every promise which I made to my father," Uddhav Thackeray said.

"There are several types of shock. Did people like it or not, it is the important part. I have spoken on this issue (alliance with NCP and Congress) several times and even people have understood this. Making promises and keeping them are two different things. If someone breaks a promise, pain and anger is obvious," he added.

The Chief Minister said that he does not know if BJP "has come out their shock till now or not."

"But I have to say if they had kept their promise what would have happened, what a big deal had I asked for? Did I ask for stars and moon? I only asked for what was decided before Lok Sabha polls, when we decided seat distribution," he said.

He further said, "Maharashtra and the country are watching (who betrayed/shocked whom), I don't need to say much on this."

Soon after the Assembly election results, Shiv Sena demanded rotation of the chief minister's post and equal power-sharing in the state government, which was rejected by then ally BJP. The weeks of political stalemate led to the imposition of President's rule on November 13.

Firm on its demands, Sena, the second-largest party in the state, did not hesitate to cobble up with the ideological opponents -- NCP and Congress -- and was given the chief minister's post.
