Billionaire philanthropist Bill Gates has hailed India's scientific innovation and capability in its endeavour to tackle the Coronavirus pandemic. 

A day after Prime Minister Narendra Modi announced that India will soon start the world largest vaccination drive, Bill gates took to micro-blogging site Twitter to say, "It's great to see India's leadership in scientific innovation and vaccine manufacturing capability as the world works to end the COVID-19 pandemic."

Bill Gates' endorsement also comes close on the heels of the Drug Controller General of India approving Serum Institute of India's 'Covishield' vaccine and Bharat Biotech's 'Covaxin' for emergency use against coronavirus.

Prime Minister Narendra Modi had on Monday hailed the scientists and technicians for their contributions. 

"The impact of any research is commercial, social and expands our understanding. Many times other potential future uses of research can't be estimated in advance, but it's for sure that research is never wasted. Just as it's said in our shastras that soul is immortal, so is research," Prime Minister Modi has said.

The World Health Organisation also hailed the first emergency use authorization given to a COVID-19 vaccine in the WHO South-East Asia region.

"This decision taken today by India will help intensify and strengthen the fight against COVID-19 pandemic in the Region. The use of the vaccine in prioritized populations, along with the continued implementation of other public health measures and community participation will be important in reducing the impact of COVID-19," the WHO said in a statement.
