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, Jul 9: The Central Board of Secondary Education has strongly defended its decision to drop topics like democratic rights, citizenship, federalism, secularism etc in the name of reducing the syllabus for Classes 9 to 12 due to COVID-19 pandemic. 

The board has claimed that the dropped lessons "are either being covered by the rationalised syllabus or in the Alternative Academic Calendar of NCERT".

The CBSE said it had to come up with the clarification after realizing its decision was "interpreted differently".

"The rationalisation of syllabus up to 30 per cent has been undertaken by the Board for nearly 190 subjects of class 9 to 12 for the academic session 2020-21 as a one-time measure only. The objective is to reduce the exam stress of students due to the prevailing health emergency situation and prevent learning gaps," it said.

While it has said that no questions can be asked from the reduced syllabus in the next board exams, the CBSE has also directed schools to follow alternative calendars prepared by the NCERT.

"Therefore each of the topics that have been wrongly mentioned in media as deleted have been covered under Alternative Academic Calendar of NCERT which is already in force for all the affiliated schools of the Board," it clarified.

On Wednesday, West Bengal CM Mamata Banerjee tweeted: "Shocked to know that the central Government has dropped topics like citizenship, federalism, secularism and partisan in the name of reducing CBSE course during the COVID crisis."

"We strongly object to this and appeal the HRD Ministry to ensure these vital lessons aren't curtailed at any cost," Banerjee added.

New Delhi, Jun 27: Delhi Environment Minister Gopal Rai on Saturday called an emergency meeting here to discuss the situation following a locust attack in neighbouring Gurugram.

The minister also directed the administration to be alert, an official said.

"After the emergency meeting, an advisory will be issued on steps to be taken to deal with the situation," Rai told PTI.

He asked the officials of the Agriculture department to make field visits to areas close to Gurugram.

The development secretary, divisional commissioner, director, Agriculture department, and the district magistrates of South Delhi and West Delhi will attend the meeting, the official said.

Earlier in the day, the skies over many parts of Gurugram turned dark as swarms of locusts descended on the town.

However, the migratory pests are likely to spare the national capital for now, officials said.

The swarms of locusts, spread across two kilometres, moved from west to east. They entered Gurugram around 11.30 am, K L Gurjar of the Locust Warning Organisation, Ministry of Agriculture, told PTI.

The pests, he said, were headed towards Faridabad and Palwal in Haryana.

Alarmed at the invasion of the locusts, which settled on trees, rooftops and plants, many residents of Gurugram shared videos from their high-rise perches.

In May, India battled a devastating desert locust outbreak. The crop-destroying swarms first attacked Rajasthan and then spread to Punjab, Gujarat, Maharashtra and Madhya Pradesh.

According to experts, broadly four species of locusts are found in India – desert locust, migratory locust, Bombay locust and tree locust. The desert locust is considered the most destructive.

It multiplies very rapidly and is capable of covering 150 kilometers in a day.

This insect, a type of a grasshopper, can eat more than its body weight. A one square kilometer of locust swarm containing around 40 million locusts can in a day eat as much food as 35,000 people.

Experts blame the growing menace of desert locusts on climate change. They say breeding of locusts is directly related to soil moisture and food availability.
