In good news amid the surging novel coronavirus infection, Russia is preparing for a mass vaccination campaign against the novel coronavirus infection in October. Russia is the first country to complete the human clinical trial of a COVID-19 vaccine.

According to Russia’s Health Minister Mikhail Murashko, the Gamaleya Institute, a state research facility in Moscow, had completed clinical trials of the vaccine and paperwork is being prepared to register it, reported news agency Reuters citing Interfax.

The Gamaleya Institute has been working on an adenovirus-based vaccine, said the report.

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.

Russia’s first potential COVID-19 vaccine would secure local regulatory approval in August and be administered to health workers soon thereafter, said the report citing sources.

More than 6.8 lakh people have died of COVID-19 globally and 1.78 crore tested positive for the disease, according to Johns Hopkins University data.

In a bid to stop the pandemic, many countries are trying to develop the COVID-19 vaccine. More than 100 possible vaccines are being developed around the world to try to stop the contagion. Of these, at least four are in final Phase-III human trials, including three developed in China and another in Britain, according to the World Health Organization (WHO) data.
