Slovakian Drug Institute Unable to Evaluate Sputnik V ‘Due to Lack of Data’ Slovakia, one of Europe’s hardest-hit countries by the pandemic, has bought 200,000 doses of the Russian vaccine but has yet to start administering shots. Federico Parra / AFP Slovakia’s State Institute for Drug Control has told the country’s Health Ministry it has been unable to evaluate the risks and benefits of Russia’s Sputnik V vaccine due to a lack of data and inconsistencies in dosages, the watchdog’s spokeswoman Magdaléna Jurkemíková told The Moscow Times on Wednesday. Slovakia, one of Europe’s hardest-hit countries by the pandemic, received 200,000 doses of the Russian vaccine on March 1 amid accusations of political maneuvering but has yet to start administering shots.
