Global leaders have lauded India's leadership in scientific innovation and decisive action to combat the COVID-19 pandemic, as the country gets set to begin the world's largest vaccination drive against the novel coronavirus.

The Drug Controller General of India on Sunday approved the Oxford COVID-19 vaccine Covishield, manufactured by the Serum Institute and indigenously developed Covaxin of Bharat Biotech, for restricted emergency use in the country, paving the way for a massive inoculation drive.

'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, co-chair of the Bill & Melinda Gates Foundation, said in a tweet on Monday, tagging the Prime Minister's Office.

Director-General of the World Health Organization Tedros Adhanom Ghebreyesus tweeted that India 'continues to take decisive action & demonstrate its resolve to end #COVID19 pandemic'.

'As the world’s largest vaccine producer, it’s well placed to do so. If we #ACTogether, we can ensure effective & safe vaccines are used to protect the most vulnerable everywhere,' Ghebreyesus said and tagged Prime Minister Narendra Modi in his tweet.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.

A day after India's drug regulator approved two vaccines for restricted emergency use, Prime Minister Modi said the world's biggest inoculation drive against coronavirus was set to begin in the country.

Praising the scientists and technicians for the 'Made in India' vaccines, he said the country was proud of them.

'World's biggest COVID-19 vaccination programme set to begin in India. For this, the country is proud of the contributions of its scientists and technicians,' Modi said.

Addressing scientists at the National Metrology Conclave, Modi had said it must be ensured that 'Made in India' products not only have global demand but also global acceptance.

Modi has assured the global community that India’s vaccine production and delivery capacity will be used to help all humanity in fighting the crisis of the COVID-19 pandemic.

'Even during these very difficult times of the raging pandemic, the pharmaceutical industry of India has sent essential medicines to more than 150 countries,' Modi had said in his pre-recorded video statement to the General Debate of the 75th session of the UN General Assembly in September last year.

In a strong assurance to the international community, that is battling the devastating coronavirus pandemic, Modi said, 'As the largest vaccine producing country in the world, I want to give one more assurance to the global community today. India’s vaccine production and delivery capacity will be used to help all humanity in fighting this crisis.'
