Russian COVID-19 Vaccine: Russia says a billion doses of its coronavirus vaccine pre-ordered by nearly 20 countries

Russian COVID-19 Vaccine: The speed at which Russia is moving to roll out its vaccine highlights its determination to win the global race for an effective product, but has stirred concerns that it may be putting national prestige before sound science and safety.

Russia has received preliminary requests for one billion doses of its COVID-19 vaccine from over 20 countries, the Indian Express reported on August 11 quoting Russian Direct Investment Fund (RDIF) CEO Kirill Dmitriev.

Earlier in the day, Russian President Vladimir Putin said Russia had become the first country in the world to grant regulatory approval to a COVID-19 vaccine after less than two months of human testing, a move hailed by Moscow as evidence of its scientific prowess.

The World Health Organisation cautioned Russia last week against rushing through the vaccine and that, coupled with the fact that Russia has only made public the results of phase one of clinical trials has led to scepticism regarding the vaccine's effectiveness and safety.

Putin, however, said the vaccine, developed by Moscow's Gamaleya Institute, was safe and that it had even been administered to one of his daughters.

"I know that it works quite effectively, forms strong immunity, and I repeat, it has passed all the needed checks," said Putin.

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.

He said he hoped the country would soon start mass producing the vaccine.

Its approval by the health ministry foreshadows the start of a larger trial involving thousands of participants, commonly known as a Phase III trial.

Such trials, which require a certain rate of participants catching the virus to observe the vaccine's effect, are normally considered essential precursors for a vaccine to receive regulatory approval.
