"The Russian single-component Sputnik Light vaccine against coronavirus has been approved by the Ministry of Health of the Islamic Republic of Iran", RDIF said in a statement.
The country approved Russia's two-dose Sputnik V vaccine back in January.
Sputnik Light is a one-component version of the Russian coronavirus vaccine, Sputnik V, developed by the Russian Direct Investment Fund and Gamaleya Institute. According to RDIF, Sputnik Light has shown 79.4% efficacy in preventing COVID-19, which is higher than some other two-dose vaccines.
