Made by the Gamaleya Research Institute of Epidemiology and Microbiology in Moscow, Sputnik V is a two-dose Covid-19 vaccine. It is the third Covid-19 vaccine which is approved by Govt of India to be administered. The Indian drug regulator has approved the emergency use of the Russian-made vaccine. According to the trial results, Sputnik V is considered to be safe for mass inoculation and has 92% efficacy which is highest among most of the vaccines available against Covid-19. The following are certain questions that people may have about Sputnik V and their answers.
The clinical trials conducted in the late phase revealed that Russia’s Sputnik V coronavirus vaccine gives around 92% protection against COVID-19.
The vaccine has generated a good immune response and is well-tolerated by people aged 18 years or older.
The vaccine uses two types of viruses (adenoviruses) that lead to the common cold in man.
The genetic information from the two viral vectors, which are the basis of infection, is separated. This is combined with a gene that leads to the SARS-CoV-2 spike protein output. The SARS-CoV-2 virus is scattered with proteins that it utilizes to enter human cells. These supposed spike proteins make an attractive target for budding vaccines and treatments.
Sputnik V is the only vaccine with two different vectors for the two shots. This creates a stronger immune response and makes the vaccine more effective against mutant coronavirus strains. This makes Sputnik V different from other COVID- 19 vaccines available.
As of now, two doses within 21 days will be administered. Sputnik V is the only vaccine that uses two different vectors for the administration of both shots. The usage of two different adenovirus vectors is said to create a more robust immune response and has made this vaccine more successful against mutants of coronavirus.
Sputnik is the first vaccine to be approved globally for Covid-19. It is one of the only three vaccines that has shown an efficacy rate of above 90%. In India, no side effects seen as of now.
With the approval of the Drugs Controller General of India (DCGI), India has become the 60th nation to allow the administration of Sputnik V amid the 2nd wave of Covid–19. The vaccine is priced at Rs 1145 in India in Private Hospitals.
The Sputnik V is a Russian vaccine, the third one after Covishield and Covaxin to be launched in India. The Russian Direct Investment Fund CEO Kirill Dmitriev has stated that Sputnik V is highly effective against British variants as well as against other new variants.
Sputnik V is supposed to be the only vaccine so far that is administered in two different doses. This mixing of vaccine doses is said to have positive results against mutants. Considering how most of the new cases in India are of the British variant, this vaccine could be a game-changer.
