Figures show 7.45 million people have now had an initial dose of a coronavirus vaccine.
Germany has said the Oxford/AstraZeneca vaccine should not be offered to people over the age of 65, a source close to the country's government has told Sky News.
It comes after Reuters reported Germany's vaccine committee made the recommendation, citing insufficient data about how effective the jab is for older people, not because of any safety concerns.
But UK prime minister Boris Johnson said he was not worried because Britain's medicines regulator had judged it is 'effective across all age groups and provides a good immune response across all age groups'.
He added "I don't agree" with the apparent assessment in Germany.
