Right now a batch of "Sputnik V" is being given to the public in Russia after some tests and clinical trials done to ensure its quality and efficacy. The said vaccine was developed by Gamaleya Research Institute of Epidemiology and Microbiology it is a Russian pharmacological company.
It is the first vaccine developed by a country for CoViD-19 so it is really a breakthrough that humanity is needing to fight the Pandemic which had affected not only the economy of many nations but also the lives of hundreds of thousands of people already.
The Lancet medical journal noted there should have been a longer clinical trial with more volunteers for the said vaccine to prove its quality and effectiveness.
Now the vaccination could get done in Moscow alone at the end of the year at the very least and at the start of next year. Other countries will be the next to try the vaccine if it would be available and if it would be reasonably priced especially if other Vaccines could get developed to compote with it.
