The government hopes to receive the COVID-19 vaccine developed by global pharmaceutical giants Pfizer and Moderna this year, said Dr VK Paul, member (health) of Centre's topmost think tank NITI Aayog.

The conditions put forth by Pfizer and Moderna are "alien to us", Dr VK Paul who is also Chairman, National Task Force, COVID-19,  said, adding that the government is working towards finding a middle ground. Dr Paul was said this during an interview to CNBC TV18 on June 21.

Dr Paul said that India has made huge progress in procuring the two vaccines in terms of working together with the companies to reach a common ground vis-à-vis viability and contract-related commitment.

"We hope to find a positive way forward. The final decision has to be compatible with Indian and with the protection that the constitution of India provides... therefore I would like to leave the point here that please trust the government of India. We have been indulged in talks with the companies to make it possible for these vaccines to come to India. Otherwise, why would go out of the way to dilute the condition of trials," he said.

Reports have claimed that both Pfizer and Moderna have sought indemnity from the Indian government. Such an indemnity has not been offered the three vaccine manufacturers whose jabs have been cleared in India so far.

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.

"And, yes  your question whether it will be this year, for these vaccines it will be this year, yes our hope is that it should be possible to have vaccines doses from these vaccine manufacturers (Pfizer and Moderna) this year," Dr Paul said.

Dr Paul also announced that Bharat Biotech has submitted its phase 3 trial efficacy data results of COVAXIN vaccine to Drug Controller General of India (DCGI) over the weekend.

"We are in touch with the key manufacturers on a very continuous basis. It is my understanding that Phase 3 data has already been submitted DCGI over the weekend. So my information is that they have made progress," he said.
