Austrian Chancellor Sebastian Kurz said on Friday that some EU countries could secretly from other states sign contracts for additional supplies of vaccine against the COVID-19, Western media quoted him as saying.

Kurz said there was evidence that indicates that there have been additional agreements between EU member states and pharmaceutical companies. He admitted that some EU countries ended up receiving more vaccines than they were supposed to according to the drug distribution rules based on the population of the states.

According to Kurz, the supply system does not correspond to the per capita quota system.

The Netherlands will not only receive more vaccines per capita by the end of June than Germany, but almost twice as much as Croatia, he added.

Vaccinations in the EU began last December. The European regulator has so far approved four coronavirus vaccines from Pfizer / BioNTech, Moderna, AstraZeneca and Johnson & Johnson.
