“It’s a huge success and I want to say many, many thanks to all those involved including half of all adults who’ve come forward.”
He added: “It’s so important because this vaccine is our way out of this pandemic, so when you get the call, please, come forward and get the jab and join the majority of adults who’ve now been jabbed.
“The UK vaccination programme is a big success story. It’s down to the hard work of many, many people.
“This isn’t easy but we’re making massive strides.”
