Those not proud of Trump calling Modi father of the nation don’t consider themselves Indians: Jitendra Singh

Riyadh, Apr 27: The government of Saudi Arabia has signed a SR995 million (approx. Dh972m) contract with China to provide Covid-19 tests for nine million people in the Kingdom.

The Saudi Press Agency, SPA, reported that the decision came "as a result of a phone call made today (Sunday) between the Custodian of the Two Holy Mosques King Salman bin Abdulaziz Al Saud and Chinese President Xi Jinping."

The contract includes providing necessary equipment and supplies, making available of 500 Chinese specialists and technicians who are specialised in performing tests, establishing six large regional laboratories throughout the Kingdom; including a mobile laboratory with a capacity of performing 10,000 tests per day. Saudi cadres will also be trained to conduct daily tests and comprehensive field tests, under the new agreement

The contract was co-signed by the National Unified Procurement Company and Chinese company Huo-yan Laboratories by Dr. Abdullah Al Rabeeah, Advisor at the Royal Court, on behalf of the Government of Saudi Arabia, and Chinese Ambassador to the Kingdom Chen Weiqing, as a representative of the Chinese Government.

The contract is one of the largest contracts that will provide diagnostic tests for the novel Coronavirus.

Tests were also purchased from several other companies from the United States, Switzerland and South Korea, bringing the number of available tests to 14.5 million, covering around 40 percent of Saudi Arabia's population, SPA added.

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.

Mumbai, Jun 1: Singer-composer Wajid Khan of music director duo Sajid-Wajid, popular for their work on superstar Salman Khan's films such as "Wanted", "Dabangg" and "Ek Tha Tiger", died in early hours of Monday in a city hospital due to complications arising from a kidney infection. He was 42.

Music composer Salim Merchant, who confirmed the news of Wajid's death, said the composer was hospitalised few days ago at Surana Hospital, Chembur where his condition deteriorated.

"He had multiple issues. He had a kidney issue and had a transplant a while ago. But recently he got to know about kidney infection... He was on the ventilator for the last four days, after his situation started getting worse. Kidney infection was the beginning and then he got critical," Salim told PTI.

The music composer duo made their Bollywood debut with Salman's 1998 movie "Pyaar Kiya Toh Darna Kya" and went on to work on actor's various films including "Garv", "Tere Naam", "Tumko Na Bhool Payenge", "Partner" and the popular "Dabangg" franchise.

Wajid also did playback for Salman in chartbusters like "Mera He Jalwa", "Fevicol Se" and for Akshay Kumar in "Chinta Ta Chita Chita" from the film "Rowdy Rathore", among others. He recently co-composed Salman's songs "Pyaar Karona" and "Bhai Bhai", which the actor released on his YouTube channel.

Wajid along with his brother Sajid served as mentor on singing reality shows "Sa Re Ga Ma Pa 2012" and "Sa Re Ga Ma Pa Singing Superstar".

The composer duo also scored IPL 4 theme song, "Dhoom Dhoom Dhoom Dhadaka", which was sung by Wajid.

Soon after the news of the composer's demise broke, many from the film fraternity took to Twitter to pay tributes.

Actor Priyanka Chopra said she will always remember Wajid's smile.

"The one thing I will always remember is Wajid bhai's laugh. Always smiling. Gone too soon. My condolences to his family and everyone grieving. Rest in peace my friend. You are in my thoughts and prayers," she posted on Twitter.

Actor Parineeti Chopra said Wajid was one of the "nicest" men in the industry.

"Always singing. All heart. Always positive. You will truly be missed Wajid bhai," she tweeted.

Actor Varun Dhawan shared a picture of his filmmaker-father David Dhawan with Wajid and remembered the musician as one of the most positive people in Bollywood.

"Shocked hearing this news @wajidkhan7 bhai was extremely close to me and my family. He was one of the most positive people to be around. We will miss you Wajid bhai thank you for the music," he wrote.

Music composer-singer Vishal Dadlani said he was "heartbroken" after hearing the news.

"Both @SajidMusicKhan and @wajidkhan7 have been close & true friends. The kind who might see the light on and show up at our studio in the middle of the night just to meet and talk and share a laugh. Can't believe Wajid and I will never speak again," he wrote.

Singer-composer Shankar Mahadevan said he was still unable to come to terms with the news of Wajid's demise.

"Shocking ! Good bye dear brother.. love you .. till we meet on the other side ! Prayers for your peaceful journey Wajid bhai," he tweeted.

Singer Javed Ali posted, "Feeling Deeply Saddened after hearing shocking news of the sudden demise of Wajid Khan. May his Soul Rest in Peace. My heartfelt condolences to his family. May Allah give strength to the family."
