Last Updated: Sputnik V Cites Tests In Hungary To Prove Reliability; Denies Claims By Slovak Drug Agency The makers of world’s first registered COVID-19 vaccine- SPUTNIK V, on May 7 informed that said vaccine proved reliable after undergoing trials in Hungary. In a recent development, the makers of world’s first registered COVID-19 vaccine- SPUTNIK V, on May 7 informed that said vaccine proved reliable after undergoing trials in Hungary as the Health Ministry of The Slovak Republic has granted approval of the same. The makers of Russia's SPUTNIK V COVID-19 vaccine clarified this approval by Slovakia’s drug watchdog- State Institute for Drug Control (SUKL) succeeded their previous dissent for the drug. Apparently, Slovak regulator- SUKL, in March, claimed SPUTNIK V they had received was not “the same vaccine reviewed in the Lancet”. As a result, Russia took back 600 of the 200,000 vaccine doses that were delivered to Slovakia in March in order to carry out its own checks. Subsequently, the batch was sent to a certified lab in Hungary because according to SPUTNIK V Russian developers- Gamaleya Research Institute of Epidemiology and Microbiology, the laboratory that SUKL had used for incorrect testing was not European Union (EU)- certified to perform such a test.
