A batch of Russia's "high efficacy" Sputnik V COVID-19 vaccine arrived in Hungary on Tuesday, the first delivery to a European Union member, said Foreign Minister Peter Szijjarto. The news coincided with the publication of a study by independent experts that Moscow's vaccine is more than 90% effective. Hungary broke ranks with the EU last month by becoming the first bloc member to approve and order Sputnik V. "Today the first batch is arriving from Russia," Szijjarto said in a video posted on his Facebook page. The first 40,000 doses had landed with two million to be delivered over three months, enough to inoculate one million people, he said.
