"One hundred and eighty-three foreign military attaches from 34 countries of the [Commonwealth of Independent States] CIS, Asia, Africa, Europe and Latin America voluntarily took part in the vaccination campaign against coronavirus with the Russian Sputnik V," the ministry said in a statement.
It added that all of them underwent a mandatory health checkup prior to inoculation. Those who had not previously had COVID-19 and had no contraindications were admitted to vaccination.
Russia's Sputnik V vaccine ranks among the world's top three and is approved in 50 countries across the world. In early February, the prestigious Lancet medical magazine published a peer-reviewed study confirming the vaccine efficacy at 91.6 percent.
