The Mongolian ambassador to Moscow and some other embassy staffers have been inoculated against COVID-19 with Russia’s Sputnik V vaccine, the diplomatic mission reported on Friday.

“I am glad to announce that diplomats from our embassy were vaccinated a long time ago, with Sputnik, to be precise. The ambassador was the first to be inoculated”, an embassy spokesperson said.

The vaccination took place at the ambassador’s initiative; most diplomatic staff members have already received the vaccine, the embassy continued.

“One or two people felt slightly weak in the first days [after the jab], while everything was fine with others”, the diplomatic mission added.

Sputnik V, developed by the Gamaleya Epidemiology and Microbiology Centre and registered by the Russian Health Ministry on 11 August, was the world’s first vaccine against the novel coronavirus. The vaccine shows 91.6 percent efficacy and is 100 percent effective against severe complications. The vaccine consists of two components that are administered to a person within a 21-day interval.
