BUDAPEST, Jan 22 (Reuters) - Hungary has signed a deal to buy Russia's Sputnik V COVID-19 vaccine, the first European Union country to do so, Foreign Minister Peter Szijjarto told a briefing during talks in Moscow on Friday.

In a live video posted on his Facebook page, Szijjarto told a joint briefing with Russia's health minister that the vaccines would arrive in three tranches, and that details about the size of the shipments would be released later.

The agreement comes days after Hungary's drug regulator gave approval for use of Britain's AstraZeneca and Russia's Sputnik V vaccines against the coronavirus, as Budapest strives to lift coronavirus lockdown measures to boost the economy. The EU's medicines regulator has yet to approve the Russian or AstraZeneca vaccine.

"I am very happy to announce that we have signed an agreement today under which Hungary can purchase a large quantity of Russia's vaccine in three tranches," Szijjarto said.

He said this could allow Hungary to lift restrictions to curb the pandemic sooner.

The European Medicines Agency (EMA) is expected to decide on the vaccine developed by AstraZeneca and Oxford University on Jan. 29.

Scientists have raised concern about the speed at which Moscow has launched its vaccine, giving the regulatory go-ahead for the shot at home and beginning mass vaccinations before full trials to test its safety and efficacy had been completed.

Moscow has said Sputnik V is 92% effective at protecting people from COVID-19 based on interim results, but has not yet released the full dataset for the trials.

Russia on Wednesday filed for registration of the Sputnik V vaccine in the EU before an EMA review next month. (Reporting by Krisztina Than and Anita Komuves; Editing by Kevin Liffey)
