European Commission President Ursula von der Leyen warned the bloc would halting shipments the UK while Britain had a higher coverage rate than its own.
She said she was “ready to use whatever tool we need” to ensure the EU had the vaccines it needed.
Reacting this afternoon Boris Johnson warned restrictions would “endanger global efforts to fight the virus”.
The Prime Minister’s official spokesman said “the global recovery from covid relies on international collaboration” as he urged the EU to stand by its commitment” not to restrict exports of vaccines.
The No10 official said: “I would point you back to the conversation the Prime Minister had with Ursula von der Leyen earlier this year.
“She confirmed then that the focus of their mechanism was on transparency and not intended to restrict exports by companies where they are fulfilling their contractual responsibilities.
“It remains the case we would expect the EU to continue to stand by its commitment.”
