We attempted to book a booster jab on the NHS website this afternoon and this is how long it took

Those aged 30 or over are now eligible to book their vaccine online via the NHS website, while people aged 18 to 29 can book there from Wednesday – but all UK adults can now go to a walk-in centre.

Here is what happened when we logged on this afternoon.

At 15.36 we were told “Lots of people are trying to book an appointment.”

We were number 3483 in the queue with an estimated waiting time of five minutes.

At 16.03, the website said there were "lots of people trying to book" but we had now gone back to number 4328 with an estimated waiting time of "about" five minutes.

At 16.13 we had made it to number 4179 in the queue still with a waiting time of “about five minutes”.

At 16.52, the message was: “We will tell you where you are in the queue and estimated wait time shortly.”

And at 17.39: “This service is currently facing extremely high demand and is now operating a queuing system. If you are unable to book now, please try again later today or tomorrow.”
