BSP leader shot dead at farmhouse in south Delhi

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.

Agra, Feb 25: The architectural grandeur of 17th century Taj Mahal and the story of its construction by Mughal Emperor Shah Jahan left US President Donald Trump "impressed" during his visit to the famed mausoleum, according to the guide who accompanied him.

Nitin Kumar, an Agra-based guide, said the first word the president said after laying his eyes on the marble marvel was "incredible".

He and First Lady Melania Trump visited on Monday the iconic Taj Mahal in Agra, the second stop on his little less than 36-hour-long trip of India, and marvelled at the Mughal-era mausoleum built as a monument of love.

After Dwight David Eisenhower (1959) and Bill Clinton (2000), he became the third US president to visit the architectural icon.

"I told them the story of the Taj Mahal, the construction, and the story behind it. President Trump got very emotional after knowing the story of Shah Jahan and his wife Mumtaz Mahal. How he was kept under house arrest by his own son Aurangzeb, and buried here at Taj, next to Mumtaz's grave, after his death," Kumar told reporters.

The couple was left speechless on the first sight of the monument, and showed interest when they were told about the history and architecture of the dome, and the design details, Kumar said.

"Melania Trump asked about the mud-pack treatment and was amazed when she got to know the details of the process," he said.

One of the most photographed sites in the world, it is always high on the itinerary of head of states visiting India.

The monument was built over a period of nearly 20 years by Shah Jahan in memory of his wife after her death in 1631.

"The Taj Mahal inspires awe, a timeless testament to the rich and diverse beauty of Indian Culture!' Thank You, India," the US President and First Lady jointly wrote in the visitors' book before signing it.

According to Mohammed Zafar, who lives close to Taj Mahal complex, Nitin has been conducting guided tours for many years. "He was selected for this VVIP visit," he said.

"Many people were taking selfies with him, after the end of the visit. So, many media persons interacted with him. He has got some instant fame of sorts," Zafar said.

Authorities at Archaeological Survey of India had "advanced the dates" for mud-pack treatment for the graves of Shah Jahan and Mumtaz Mahal at Taj Mahal in view of the US President Trump's visit to Taj, a senior official had earlier said.

New Delhi, Mar 31: India is likely to blacklist about 300 foreigners who came from 16 countries, including Malaysia and Thailand, on tourist visas but attended an Islamic congregation at Nizamuddin here that has become a key source for the spread of coronavirus in the country, officials said on Tuesday.
