Indian drugmaker Bharat Biotech on June 30 said it had not received an advance payment nor supplied coronavirus vaccines to the Brazilian government, which suspended the $324-million deal following a firestorm of allegations of graft.

The company followed the procedure laid down globally for procurement of vaccines by governments, the Hyderabad-based vaccine-maker said in response to reports of “serious accusations” of irregularities.

"During the past few weeks, there have been reports in the media at large misrepresenting the procurement process of Covaxin in Brazil and other countries," the company said.

The deal has become the latest problem for Brazilian President Jair Bolsonaro who faces elections next years and is under fire for mishandling the coronavirus outbreak in the country, where 500,000 people have died of COVID.

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.
