Why Sputnik V vaccine rollout may not hit full capacity until August-September

Imports of the vaccine from Russia are delayed because of heavy orders from several countries and a likely diversion of supplies for local inoculation drives amid a spike in infections caused by the Delta variant of the coronavirus

The Sputnik V COVID-19 vaccine rollout in India may not reach full capacity until August-September because manufacturers in Russia are struggling to keep pace with export orders, sources told Moneycontrol.

Additionally, Russia and other countries are seeing a surge of COVID-19 infections linked to the Delta variant and the authorities may divert some of the supplies to their local inoculation drives.

The vaccine developed by Gamaleya National Center of Epidemiology and Microbiology in Moscow with backing from Russia’s sovereign wealth fund is produced by Binnopharm, R-Pharm, Generium and other pharmaceutical companies. Binnopharm can produce 1.5 million doses of the vaccine per year.

The Indian government currently estimates it will get at least 100 million doses of Sputnik V by December, compared with a projection in May of about 156 million doses. The procurement is part of a plan to vaccinate all of India’s adult population against COVID-19 by December 31.

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.
