Government says working with Pfizer for 'earliest possible import' of COVID vaccine

Buying vaccines internationally is not similar to buying off-the- shelf items. Vaccines are in a limited supply and companies have their own priorities, game plans and compulsions, the government has said.

The government has said it has been in talks with all major international vaccine manufacturers, including Pfizer, from mid-2020 for procuring COVID-19 vaccines.

"As soon as Pfizer indicated vaccine availability, the central government and the company are working together for the earliest possible import of the vaccine," the government said in a press release on May 27.

India’s effort to step up vaccination has been hobbled by a shortage, with several states forced to put on hold jabs for the 18-45 age group. Some states launched global tenders for vaccines but haven’t met with much success, with most vaccine makers insisting on dealing with the Union government only.

Multiple rounds of discussions have been held with Pfizer, Johnson & Johnson and Moderna. The government offered all assistance to have them supply or manufacture their vaccines in India, it said.

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.
