"Cambodia has become the 71st nation, where the use of Sputnik V vaccine is approved. The registration was made under the emergency use authorization. The total population of all the countries that approved Sputnik V amounts to 4 billion people or more than 50% of the population of the Earth," the RDIF statement reads.
Sputnik V was unveiled on 11 August 2020 to become the world's first registered coronavirus vaccine. It is based on a human adenovirus vector platform. According to RDIF, which supported the creation of the Sputnik V vaccine developed by the Gamaleya Centre, the vaccine's efficacy is 97.6%, based on the analysis of data on the incidence of the COVID-19 infection among Russians vaccinated with both vaccine components between 5 December 2020 and 31 March 2021.
