China moving ahead, talking about temples and mosques will waste our time: Ex-Navy chief

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.

These foreigners were among around 8,000 people who attended the Tabligh-e-Jamaat at Nizamuddin Markaz facility in March, many of whom have shown symptoms of COVID-19, a Union Home Ministry officlal said.

About 30 of those who attended the Nizamuddin event in mid-March tested positive and at least three have succumbed to the infection in last few days.

"Those who came on tourist visa but attended the Nizamuddin event stands being in our blacklist as they have violated the visa conditions. Tourist visa holders can't attend religious function," a Union Home ministry official said.

If a foreigner is put in the Home ministry's blacklist, he or she can't travel to India in future.

A total of 281 foreigners were found by the police at the Nizamuddin campus in the last two days.

They include 19 people from Nepal, 20 people from Malaysia, one from Afghanistan, 33 from Myanmar, one from Algeria, one from Djibouti, 28 from Kyrgystan, 72 from Indonesia, 7 from Thailand, 34 from Sri Lanka, 19 from Bangladesh, three from England, one from Singapore, four from Fiji, one from France and one from Kuwait.

Most of these foreigners came on a tourist visa, an official said.

New Delhi, Jun 4: India's Defence Secretary Ajay Kumar tested positive for COVID-19 on Wednesday, following which the defence ministry carried out a massive contact-tracing exercise, official sources said.

Kumar's condition is stable and he is currently under home-quarantine, they said.

At least 35 officials working at the ministry's headquarters in South Block in the Raisina Hills have been sent on home quarantine after reports of Kumar testing positive for the infection emerged on Wednesday morning.

There was no official comment on Kumar's health condition. The defence ministry spokesperson refused to comment on the issue.

It is learnt that Defence Minister Rajnath Singh did not attend office as part of a precautionary measure.

The offices of the defence minister, the defence secretary, the Army Chief and the Navy Chief are on the first floor of the South Block.

The sources said all laid down protocols on contact-tracing and quarantining of people are being scrupulously followed.

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.
