The SARS-CoV-2 strain was isolated in NIV and transferred to Bharat Biotech, which has developed the indigenous, inactivated vaccine at its biosafety level-3 (BSL-3) high containment facility located in Genome Valley on the outskirts of Hyderabad.

Bharat Biotech is committed to advancing vaccine development as a matter of national importance to demonstrate India's strength in handling future pandemics, Joint Managing Director Suchitra Ella, was quoted as saying in the statement.

Bharat Biotech's Covid vaccine candidate Covaxin is set to undergo human clinical trials in July.

CanSino added that it can not guarantee the vaccine - which had its phase one and two clinical trials done in China - will ultimately be commercialised.

Also in the race are the China National Biotec Group (CNBG), who said on Sunday that early human test results for a coronavirus vaccine candidate suggested it could be safe and effective, the second vaccine candidate from the firm to show encouraging results in a clinical trial.

"Our collaboration with ICMR and NIV has been instrumental in this development".

He was in 2001's Ocean's Eleven and its two sequels as conman Saul Bloom , and had a double act with Mel Brooks . On the show , Reiner would guest star as temperamental show host Alan Brady, and would write numerous episodes.

Other companies, such as Jansen Pharmaceuticals, will start clinical trials based on adenovirus-based vaccines, but said they expect the first results only next year.

Shots will not be able to get approval if studies only show that they lead to the development of antibodies in the bloodstream, which is not proof that the vaccine can actually prevent coronavirus infection.

The 50% threshold is a gauge similar to the one used to measure the effectiveness of typical flu vaccines, said Harvard's public health immunologist and professor Barry Bloom.

In the bouquet of 16 Vaccines it has developed and markets, with necessary global regulatory approvals and WHO-pre-qualifications are the Polio, Rabies, Rotavirus, Japanese Encephalitis, Chikungunya and Zika.

China is just one of several countries rushing to produce a vaccine for the novel coronavirus, which has now infected more than 10.3 million people worldwide and killed at least 505,000.

The COVID-19 vaccine, developed by researchers at the University of Oxford, led by Irish scientist Adrian Hill, is the "leading candidate" for a working vaccine, the World Health Organization has stated.
