Prime Minister Boris Johnson has warned that Britain faces another wave of coronavirus infections, following rising cases in Europe.
Mr Johnson said he expected the third wave of Covid-19 infections, seen in countries such as France and Italy, to "wash up on our shores as well".
But Mr Johnson said he did not think the European Union wanted to block vaccine exports from reaching the UK, following suggestions Brussels could stop supplies from crossing the Channel amid struggles with its own rollout.
Speaking to broadcasters at BAE Systems in Lancashire on Monday, Mr Johnson said: "I've talked to our (European) friends repeatedly over the period - we're all facing the same pandemic, we all have the same problems.
"If there is one thing that is worth stressing it's that on the continent right now you can see sadly there is a third wave under way.
"People in this country should be under no illusions that previous experience has taught us that when a wave hits our friends, it washes up on our shores as well.
"I expect that we will feel those effects in due course.
"That's why we're getting on with our vaccination programme as fast as we can but a vaccination campaign and developing vaccines, rolling them out - these are international projects and they require international co-operation."
His comments come after several regions in France, including Paris, spent their first weekend under a limited month-long lockdown.

Care minister Helen Whately, speaking earlier, said it was "premature" to consider booking a holiday abroad with coronavirus rates on the rise elsewhere and urged Britons to "hold off" on making foreign travel plans.
She told BBC Breakfast: "What I would counsel is caution at the moment for people to hold off on booking because, as anybody can see, we are in a situation where there are rising rates in many countries in Europe and we know that also something that comes with rising rates is increased rates of variants."
