England’s chief medical officer Professor Chris Whitty has warned that the UK will go through the “most dangerous time” of the pandemic in the weeks before the vaccine rollout has an effect.
Speaking to BBC Breakfast, Whitty urged people to “double down” and stop any “unnecessary contacts”.
He said: “What we need to do before the vaccines have had their effect - because it’s going to take several weeks before that happens - is we need to really double down.
“This is everybody’s problem, any single unnecessary contact with someone is a potential link in a chain of transmission that will lead to a vulnerable person.
“We’ve all got to, as individuals, help the NHS, help our fellow citizens, by minimising the amount of unnecessary contacts we have.”
The professor added that the virus can be passed on in any place where people from different households get together, explaining that it can spread through meeting in homes, in shops and even outdoors.
“It doesn’t care who you are, it doesn't care whether you’re friends. If you meet from another household, the virus has an opportunity to be transmitted,” Whitty said.
‘Take the rules very, very seriously’
Whitty urged members of the public to take the current rules “very, very seriously” and said that people should be looking to cut out any necessary contacts they have.
He said: “In a sense tinkering with the rules may be useful, but the far more important thing is that everybody abides by the spirit of the rules that are there at the moment.
“Everybody knows what they need to do. And I think that’s the key thing - minimise the number of contacts.”
Vaccines minister Nadhim Zahwai said: “These rules are not boundaries to be pushed at, they are rules to help all of us bring down the death rate, bring down the pressure on the NHS and help us, help me, keep vaccinating so that we can actually get ahead of the virus.”

These are the new rules currently in place in England, Scotland, Northern Ireland and Wales at a glance.
