Hungarian lab to examine Sputnik V for Slovakia â deputy premier The decision was made during Fridayâs visit to Budapest by Slovakian deputy premier and Finance Minister Igor Matov PRAGUE, April 10. /TASS/. A formal review of Russia’s Sputnik V vaccine for Slovakia will be carried out by a Hungarian lab, part of Europe’s OMCL (Official Medicines Control Laboratory) network. The decision was made during Friday’s visit to Budapest by Slovakian deputy premier and Finance Minister Igor Matovic, who recently had to resign from the post of the country’s premier. His resignation came as a result of a governmental crisis triggered by Sputnik V purchases, made before the jab’s use is officially authorized in the European Union.
