The Italian government has blocked the export of an Oxford-AstraZeneca vaccine shipment to Australia.

The decision affects 250,000 doses of the vaccine produced at an AstraZeneca facility in Italy.

Italy is the first EU country to use the bloc's new regulations allowing exports to be stopped if the company providing the vaccines has failed to meet its obligations to the EU.
