Pfizer and BioNTech’s COVID-19 vaccine candidate, if proven to be safe and effective by federal regulators, could reach Americans before 2020-end, according to Pfizer CEO Albert Bourla.

"I cannot say what the United States Food and Drugs Administration (FDA) will do, but I think is a likely scenario and we are preparing for it," Bourla said during American channel CBS’ “Face the Nation” segment.

He said they “will be ready” in case of good indicators from the vaccine study, FDA and advisory committee and have already “started manufacturing and have already manufactured hundreds of thousands of doses” in preparation, Fox Business reported.

According to Bourla, Pfizer’s study will show if there is a “good chance if the product works” by October-end, the distribution would depend on license issuances from regulators such as the FDA.

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.
