France, Italy, Austria, Hungary and the Czech Republic received their first shipments of the Oxford-AstraZeneca vaccine this weekend as the EU tries to ramp up its rollout.
Several European countries have already announced that they will not be supplying the vaccine to those over 65, because of the limited amount of trial data for that age group.
Now there are concerns that the vaccine may have reduced effectiveness on coronovirus variants.
UK - minority scepticism?
More than 12 million people in the UK have now received a first dose of a coronavirus vaccine. The Pfizer-BioNtech and Oxford-Astrazeneca vaccines are currently being administered across the country.
