Europe has nearly eight million doses of AstraZeneca vaccine sitting unused, European Centre for Disease Prevention and Control data shows as of Sunday.
That is more than half the total number of doses distributed to European nations, the data shows.
It shows 14,851,497 doses have been distributed, while 6,895,411 have been used – leaving 7,970,323 doses unused.
Only Lithuania has used its full allocation, the data shows.
The ECDC notes that member states are asked to upload data at least twice a week, on Tuesdays for the preceding week and Friday for the current week, so there may be a lag in reporting.
