New Delhi, Jul 1: 18,653 COVID-19 cases have been reported in India in the last 24 hours, taking the country's tally of coronavirus cases to 5,85,493, informed the Union Health and Family Welfare Ministry on Wednesday.

As per the Ministry, there are presently 2,20,114 active cases in the country. The number of patients cured/discharged and migrated stands at 3,47,979.

507 deaths due to COVID-19 were reported in the last 24 hours taking the total deaths due to the virus to 17,400.

According to the ministry, Maharashtra is the worst-affected state by the virus with 1,74,761 cases including 7,855 fatalities.

Tamil Nadu is the second worst-hit state with 90,167 cases including 1,201 deaths. Meanwhile, Delhi has a total of 87,360 cases.

The Indian Council of Medical Research said that a total number of 86,26,585 tested up to June 30 of which 2,17,931 samples were tested on Tuesday.

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, May 29: With the highest spike of 7,466 more COVID-19 cases and 175 deaths reported in the past 24 hours, India's COVID-19 tally reached 1,65,799 on Friday, according to the Union Ministry of Health and Family Welfare.

The number of active coronavirus cases stands at 89,987 while 71,105 people have been cured or recovered and one patient has migrated, it said. The death toll due to the infection has reached 4,706 in the country.

Maharashtra is the worst affected state with 59,546 cases. Tamil Nadu has recorded as many as 19,372 cases while Gujarat and Delhi have recorded 15,562 and 16,281 coronavirus cases respectively.
