"The efficacy results of the one-shot Sputnik Light vaccine against the Delta variant of coronavirus significantly outperform those of a number of two-shot vaccines. Crucially, the data from the Gamaleya Center confirms that the one-shot Sputnik Light vaccine is among the best vaccines against coronavirus," Dmitriev said.
