Austria's Chancellor Sebastian Kurz on Friday suggested that some European countries may have signed "secret contracts" with vaccine companies to receive more vaccines than they were entitled to based on EU rules.
EU members have agreed that vaccines should be distributed among countries based on population size, but Kurz said that after comparing total procurement between member states, it became clear that "deliveries do not follow the per capita quota system".
"There are clues that point to so-called bazaars where additional agreements between member states and pharmaceutical companies were made," Kurz said.
"Malta will receive three times as many doses per capita as Bulgaria until the end of July," he said.
"The Netherlands would not only receive more doses of vaccine per capita until the end of June than Germany, but almost twice as many as Croatia," Kurz said.
"This is in clear contradiction to the political goals of the EU," he said.
