The European Union is struggling to show complete coronavirus vaccination solidarity among member nations after a week of negotiations over the distribution of extra doses.

Five EU nations that struggled most to get their vaccination drive going were given extra doses from an alliance of 19 other countries. Three nations were not part of the deal, however, showing the difficulties of compromise politics when Covid-19 cases are surging again.

At an EU summit last week, Austrian Chancellor Sebastian Kurz criticised the allocation of shots in the 27-nation bloc, saying that some countries were receiving more than their fair share at the cost of others. EU leaders failed to agree on a correction mechanism, leaving it to their EU ambassadors.

Late on Thursday, a deal was reached on how to distribute an early batch of 10 million Pfizer-BioNTech doses with Bulgaria, Croatia, Estonia, Latvia and Slovakia receiving a proportionally large number of doses. Austria, along with the Czech Republic and Slovenia, did not get additional shots.

“We are grateful for the remarkable efforts” and solidarity of fellow EU member states, Latvian Prime Minister Krisjanis Kariņs said. He said the extra shots “will bring us closer to our common goal – a collective immunity across the EU”.

Under the joint procurement programme set up by the European Commission, doses are allocated on a pro rata basis, but some nations are taking less than their share.

A large majority of EU members think the system is working well, but said some nations made a mistake to focus on AstraZeneca shots instead of diversifying their vaccine portfolios.

AstraZeneca shots are cheaper and easier to handle than vaccines from Pfizer-BioNTech or Moderna.

Overall, the EU continues to lag well behind nations like the United Kingdom and United States when it comes to vaccinations.
