The EU's drugs regulator has approved the use of the AstraZeneca COVID vaccine for people aged over 18.
The vaccine, co-developed by Oxford University, is the third to be approved by the bloc.
Individual countries can still decide who the vaccines should be given to, once they have been approved.
Earlier this week, Germany's vaccine commission said it could not recommend the use of the jab in people aged over 65.
It cited a lack of data on how it affected this age group.
The U.K. has already started administering the AstraZeneca vaccine.
