SARAJEVO, Bosnia-Herzegovina — Vaccinations have started in Bosnia with Russia’s Sputnik V shots administered in the Serb-run part of the country.

The Bosnian Serb-dominated entity called Republika Srpska has acquired 2,000 vaccines from its ally Russia. The inoculation kicked off Friday with the head of the main hospital in the northwest town of Banja Luka getting the first shot.

Bosnia consists of a Serbian run and an entity run by the country’s Bosniaks, who are mostly Muslims, and Croats. The two semi-autonomous regions were established in a U.S. peace agreement that ended the 1992-95 war.

The Bosnian Serbs and neighboring Serbia have traditionally close links to Moscow. The Bosniak-Croat entity dubbed Federation of Bosnia-Herzegovina is yet to receive vaccines via the international COVAX program.
