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.

Lukung, Jul 17: Union Defence Minister Rajnath Singh on Friday assured that not an inch of our land can be taken by any power in the world while he interacted with the Indian Army and ITBP personnel at Lukung.

Referring to the India-China border standoff, he said, "Talks are underway to resolve the border dispute but to what extent it can be resolved I cannot guarantee. I can assure you, not one inch of our land can be taken by any power in the world."

Emphasising on finding a diplomatic solution to the standoff, he further said, "If a solution can be found by talks, there is nothing better."
"Recently what happened between troops of India and China at PP14, how some of our personnel sacrificed their lives protecting our border. I am happy to meet you all but also saddened because of their loss. I pay my tributes to them," he added.

Singh interacted with the Army and Paramilitary troops here along with Chief of Defence Staff General Bipin Rawat and Army Chief General MM Naravane.

Earlier today, the Defence Minister witnessed para dropping and scoping weapons here. He also inspected a Pika machine gun.

Indian Army T-90 tanks and BMP infantry combat vehicles carried out the exercise at Stakna, Leh in presence of Singh, Chief of Defence Staff and Army Chief.

Defence Minister is on a two-day visit to Ladakh and Jammu and Kashmir. He will take stock of the situation at both the Line of Actual Control (LAC) and the Line of Control (LOC).

While Pakistan constantly violates ceasefire from across the LoC, China has continued to intrude into Indian territory in Ladakh region in recent past, escalating tensions between India and its eastern neighbour.

On June 15, twenty Indian soldiers laid out their lives during combat with Chinese forces in Galwan valley, leading to tensions between both nations. Chinese soldiers subsequently started moving back following dialogues between two countries through the military level and diplomatic level.

Singh was accompanied by the Chief of Defence Staff General Bipin Rawat and Army Chief General MM Naravane.

New Delhi, Feb 11: Cheaper lending rates in the country along with the government's booster via tax cuts seem to have had little effect on vehicle sales in January, with car sales decreasing by over 14,531 units, or slightly over 8 per cent, compared to January last year.

According to Rajan Wadhera, President of industry body Society of Indian Automobile Manufacturers (SIAM), which gives out the auto sales numbers, the overall slump in vehicle sales in India was due to the "rising cost of vehicle ownership and slower growth in GDP".

Barring three-wheelers, all other segments showed de-growth.

Vehicle sales across segments have been declining for over a year now. SIAM sales data last month compared with that of January 2019 showed that domestic passenger vehicle sales slipped 6.2 per cent to 262,714 units. The decline in car sales stood at 8.1 per cent, and two-wheelers 16.06 per cent.

Sales of commercial vehicles, an indicator of industrial health in the economy, slipped by 14.04 per cent to 75,289 units last month, while the vehicle sales across categories registered a de-growth of 13.83 per cent to 17,39,975 units from 20,19,253 units in January 2019, SIAM said.

However, Wadhera said, they were hopeful that recent government announcements on infrastructure and rural economy would support growth of vehicle sales, especially in the commercial and two-wheeler segments.

"We are looking forward to the early announcement of an incentive-based scrappage policy in the context of the recent assurances by the government," Wadhera said.
