"If the experts at NNK determine that the vaccine is safe, effective and can be administered as a booster jab, then commercial talks on procurement will start with the manufacturer," Minister of Foreign Affairs and Trade Péter Szijjártó said.

Szijjártó noted that the single-dose Sputnik Light vaccine is already in use in the United Arab Emirates, Bahrein, Argentina, and India, and has been given permission to be used in San Marino and is under testing in Serbia.

The minister said one of the greatest successes last year was the Hungarian-Russian cooperation regarding vaccines, which helped with immunizing nearly 1 million Hungarians.
