The makers of the Russian vaccine Sputnik-V have succeeded in developing a single-dose vaccine for COVID-19. The name of this vaccine is Sputnik Light and it is 79.4% effective against the infection. It is a new vaccine of the same Sputnik family, which is currently being used in 60 countries of the world. India has also approved Sputnik-V. Its first shipment has arrived in India on May 1st. Therefore, it is expected that its new single-shot vaccine may be approved in the country in the coming time. Notably, NITI Aayog has ordered 200 viles for testing in India.
Sputnik Light is developed by the Gamalaya Research Institute of Moscow. Like Sputnik-V, it is also financed by the Russian Direct Investment Fund (RDIF).CEO of RDIF Kirill Dimitriev told that its price worldwide would be less than $10.
The phase-3 trial of this vaccine involved 7000 people. The trials were conducted in Russia, UAE and Ghana. Data of trials was analysed 28 days later. The results found that this vaccine is effective on all new strains of the virus. Its data suggests that it is more effective than many other double dose vaccines.

India approved 3 vaccines so far
It is a viral vector vaccine. It uses the adenovirus ChAD0x1 found in chimpanzee to produce a spike protein similar to that of the coronavirus. It develops protection against those spikes. Which ultimately gives protection from the virus.
It is developed in a traditional manner of using the attenuated virus. In other words, the dead virus is injected into the body. This causes antibody response and the body produces antibodies to detect and fight the virus.
It is also a viral vector vaccine. But unlike COVISHIELD, it is made up of two viruses rather than one. Both doses of this vaccine contain different vectors.
