Austria on Tuesday announced it plans to funnel 651,000 shots of BioNTech and Pfizer’s COVID-19 vaccine to 6 countries of the Western Balkans by August as part of a European Union scheme to assist neighboring countries and Africa.

The European Commission outlined its plans for a vaccine- sharing mechanism in January. Austria said it would serve as that mechanism’s coordinator for the Western Balkans, and that this first distribution of jabs may be followed by others.

Serbia has one of the highest inoculation rates in Europe, but the 4 other non-EU countries of the former Yugoslavia and Albania have had less success. In Bosnia, the shortage of vaccines has led to street demonstrations.

“With this initiative we are showing that we are not leaving the region behind,” Austrian Foreign Minister Alexander Schallenberg told a news conference. His country, the successor state to an empire that once stretched deep into the Balkans, maintains close relations with countries in the region.

Austria has negotiated agreements between BioNTech and Pfizer and the recipient countries, its Foreign Ministry said. It will provide bridge financing of 11 million euros ($13 million), though the shots will be paid for from EU assistance funds for EU candidate and potential candidate countries.

“There is absolutely no connection here to the provision of vaccines in Austria and in other (EU) member states,” said Schallenberg, whose government faces rising public frustration with the slow pace of inoculations.

“These shots are not from a national quota. These are vaccine doses that the EU explicitly secured from the beginning for the purpose of passing them on to partners.”

He said they will be distributed from early May according to which countries need them most. Bosnia will get the biggest share with 214,000 jabs, followed by Albania with 145,000 and North Macedonia with 119,000. Serbia is last with 36,000.
