Sir Paul McCartney “can’t wait” to have the coronavirus jab.

He said the vaccine was a “great breakthrough”.

And he added:

“I’ll have it as soon as I’m allowed.

“I’m a grandad and you don’t want grandad to collapse.

“You’ve got to stay strong, that’s all you can do, or you go under.

“I know we’ll come through this.”

Sir Paul, 78, revealed he spent most of lockdown in the UK with his daughter Mary and her family.

He told The Sun:

“A lot of friends were saying, ‘Wow, I’ve never spent so much time with my wife!’

“And it was great because I got to spend time with my daughter Mary and her family.

“So that meant I had four of my grandkids together, which was really nice.

“Great family, very loving and we’re in the countryside so, if we went out to get a breath of fresh air, we didn’t meet anyone.

“I was a little worried about telling anyone I was having a good time because I knew so many people weren’t but most people I talked to said, ‘Oh yeah, there’s a silver lining’.”

However, the former Beatle isn’t so sure people will comply with restrictions indefinitely.

He said: “You can’t just lockdown a whole country. . .  unless you’re China.

“We’re all brought up to enjoy the great freedom that we have in a democracy.”
