Professor Chris Witty told MPs that all the modelling suggests that is going to be a further surge in infections in the late summer or autumn, and many vulnerable people still are not protected.

Our health editor, Hugh Pym, has more details.

Yeah, the vaccination program rolls on people in Darby queuing and happy to get their jabs.

55 to 59 year olds in England now getting their invitations relief because I thought I'd have to wait quite a while.

But I got the letter yesterday and I'm booked in today, which is quite good.

Been waiting quite a long time.

Yeah, but yeah, the sooner the better for me.

Government advisers say the vaccination plan is going very well, but they warn that while people will get some protection against serious illness, the virus won't go away.

In fact, it'll probably spread faster as lockdown is eased.

Suggest there is going to find the people who work in hospitals and schools in England have opened up this week.

At this primary and knowledge, there was even a mini circus to welcome Children back and reassure them.

Officials say they need up to five weeks to see how the reopening affects the spread of the virus.

Parents meet people who perhaps weren't going into work.

Some of them may go into work.

As a result, it changes a number of things, all of which may have pressure on on transmission.

Lockdown easing in England continues provisionally from March the 29th, with some outdoor meetings and sports allowed from April.

The 12th non essential retail outdoor hospitality and some leisure facilities are set to reopen from May 17th.

Some indoor meetings and hospitality will be allowed, and June the 21st will be the earliest possible date for a full reopening.

The government advisers say.

It can't go any quicker.

What the government has been told over and again is take this study and what we don't want to do is accelerate into trouble and then have to reverse straight back out again, open things up and immediately closing down.

From Friday in Scotland, up to four people will be able to meet outdoors and some adult sports will resume.

The first minister said they were heading in the right direction, but it was too soon to take a foot off the brake.

If we continue to prioritize Children's education, as I believe we should, and indeed must our scope to make further changes will be limited while we are still rolling out the vaccine case numbers may be falling but are still relatively high.

The message from ministers and officials around the U.

K is that the grounds for hope must be balanced by caution.
