That's all for today. Join us tomorrow morning for all the latest updates on the coronavirus pandemic.

We're bringing our live page to a close. Here is a brief round-up of today's main headlines from the UK and around the world.

• Nineteen people who tested positive for coronavirus have died in the past 24 hours in the UK. It's more evidence of a steady fall in deaths attributed to the virus.
• More than 30m people in the UK have now received their first dose of a Covid vaccine, with Health Secretary Matt Hancock calling it "a phenomenal achievement".
• A third vaccine - the Moderna vaccine - is expected to be rolled out in the UK next month. And Culture Secretary Oliver Dowden said he was confident vaccinations remained on schedule, with the entire adult population given both doses by the end of July.
• Serbia has been inoculating citizens of neighbouring countries amid a surplus of vaccines and a reluctance among many Serbs to have the jab, BBC World Service reported. Queues were seen on the borders with North Macedonia and Bosnia.
• From 6 April, lorry drivers travelling to England from outside the UK, who stay for two days or more, with be required to take frequent tests - according to the length of their stay. Aircraft cabin crew, prison escorts and seasonal workers are also among those affected by the new rules.
• Poland reported 29,253 new coronavirus cases on Sunday, up 34% compared with one week ago. New daily infections reached all-time highs last week, exceeding 35,000 on Friday. Officials attribute the spike in infections to the highly contagious UK variant.

The Moderna jab - due to arrive in the UK next month - will give the UK "an extra line of security" after concerns were raised last week that supply chains of other vaccines may be held up.

So says Professor Adam Finn, from the Joint Committee on Vaccination and Immunisation

"The quantities that Moderna are capable of providing are likely to be many fewer doses than we are seeing from AstraZeneca and Pfizer," Prof Finn told the PA news agency.

"Partly because they are a small outfit and partly because they are primarily directing their supplies towards the US rather than Europe.

"So I don't think it's a game changer, I think it's an incremental change.

"It adds an extra string to our bow, if you like, and it gives us an extra line of security."

That means it is due to arrive in the UK in the same month that the NHS has warned of a "significant reduction" in vaccine supplies elsewhere.

Moderna is the third vaccine of seven that the UK has put in an order for - and the UK is lined up to receive 17 million doses.

Here's some more detail - and charts - on those figures from earlier.

We carried the story of a steady fall in deaths with coronavirus - 19 deaths in the past 24 hours (reported on Sunday).

The number of cases continues to dip. They are now on a par with the numbers being reported last September.

Meanwhile the government's vaccination schedule remains on track.

Some 57% of all UK adults have had a first jab, while 6% of adults have had a second dose, the government said.

However, data shows that the rate at which first vaccines were given accelerated sharply from mid-January. But it's expected to become more of a challenge in coming weeks to deliver the same number of second jabs.

Research has shown pets can have a huge benefit to our mental health - especially this past year.

"I don't know what I would have done without him," 24-year-old Francesca Balon tells Newsbeat.

She's registered blind and credits her guide dog, Sean, with getting her through a year of lockdowns.

"He's a real character and it's funny because he's so clever when he's working but he has absolutely no common sense," she says.

Francesca had Sean three years ago when her vision started to worsen, hitting her confidence.

The Met Police has urged Londoners to remain "vigilant" when lockdown restrictions ease tomorrow, with groups of up to six people, or two households, able to meet outside.

While people will also be allowed to take part in formally organised outdoor sport, large gatherings - unless certain exemptions apply - will remain unlawful and risk further spreading the virus, the force warned.

The Met's deputy assistant commissioner, Jane Connors, said: "We must not let Monday's news distract us, or usher in any complacency."

But she said the risk of Covid-19 "has not vanished" and wherever possible people should "continue to be vigilant, minimise our contact as much as possible, wear a face covering where required and keep ourselves safe".

"That means avoiding any large gathering," she added.

The force said it will continue to take enforcement action and hand out fines for "house parties or dangerous raves", adding it makes "no apology for our tough stance" on shutting down large gatherings which risk public safety.

Official government figures indicate 19 people who tested positive for coronavirus within the past 28 days have died in the past 24 hours.

This compares to the 33 deaths reported last Sunday. Figures on Sunday and Monday tend to be lower due to a lag in reporting.

Data also show there have been a further 3,862 positive cases - significantly lower than in recent days and the lowest daily figure since 17 September.

As reported earlier, the number of first dose vaccinations has topped 30m - while more than 3.5m have received both doses.

The "tireless efforts" of medical staff, pharmacists and volunteers lay behind the success of the UK's vaccine programme, the vaccines minister has said.

As the number of first jabs passes 30m, Nadhim Zahawi said he was "immensely proud" of the programme's speed.

He urged those who are eligible for a jab - now all those over-50 - to come forward.

Health Secretary Matt Hancock added: “The vaccine is saving lives and is our route out of this pandemic. I want to say a massive thanks to the team.

“When you get the call - get the jab.”

The latest milestone was reached after Saturday saw 650,000 vaccinations in a single day, according to the Department of Health.

Some 57% of all UK adults have had a jab - 6% of adults have now had a second dose, the government said.

Meanwhile, the department said "real-world" data showed both the Pfizer and Oxford-AstraZeneca vaccines were "highly effective" in reducing Covid-19 among older people aged 70 years and over.

For much of the past year Westminster has felt deserted.

When Boris Johnson delivered his first stay-at-home order last March, the Palace of Westminster - better known as the Houses of Parliament - changed overnight.

The tea rooms fell silent. The pubs shut. And the seemingly endless corridors emptied, save for a smattering of hand sanitising stations.

But as many MPs Zoomed into debates from the relative comfort of home, the staff of the House of Commons Heritage Cleaning team have been present throughout.

"It's important to have the place as safe as possible for the people who are still working here," says Elizabeth Rubiopuello.

So who are the heritage cleaners, what have they been doing differently over the past year - and what challenges have they faced?

Westminster Hour's Jack Fenwick has been to Parliament to talk to them.

More than 30m people in the UK have now received the first dose of a Covid vaccine.

Health Secretary Matt Hancock tweeted that it was "a phenomenal achievement".

Public Health England figures show 25,651,406 first jabs have been administered in England. Separate figures show 2,385,709 first doses have been given in Scotland, 1,387,583 in Wales and 726,589 in Northern Ireland.

It brings the total number of first vaccinations across the four nations to 30,151,287.

Wales' first minister will set out the next steps for reopening society there on Thursday and give hospitality bosses "the certainty that it's looking for".

But Mark Drakeford warned he would not give "false assurances too far into the future" as non-essential retailers, gyms and tourism sector hope to reopen.

He said he would set out "the prospectus through the whole of April and into May".

But he told BBC One's Andrew Marr Show it was "inherently an uncertain time".

Drakeford said he hoped people would be able to enjoy outdoor hospitality by the end of April but meeting indoors would "likely have to wait until May".

On Saturday, Wales became the first UK nation to lift travel restrictions within its borders.

Can you become reinfected with coronavirus if you've already had it once?

It seems the answer lies in how our immune system works.

Serbia has been inoculating citizens of neighbouring countries amid a surplus of vaccines and a reluctance among many Serbs to have the jab, BBC World Service reported.

Queues were seen on the borders with North Macedonia and Bosnia as word got out that vaccines were being distributed for free in Belgrade.

A German doctor was also reported to be among those getting a vaccine at the main centre in Belgrade, as the rollout in Germany struggles to keep pace with a third wave of coronavirus infections there.

Serbia has also begun vaccinating refugees in camps, in a move praised by the UN Refugee Agency.

The return of the legal right in England to go for a walk in the rain with five other people feels like quite a big moment.

And that reminds us of something: alongside the health emergency, the hundreds of thousands of grieving relatives and an economic crisis, this is the ongoing era of liberties crushed for everyone.

That’s why the government is so desperate to avoid the psychological whiplash of yet another slamming on of the brakes, or a reversal.

That’s why there’s the constant refrain of the roadmap being "cautious, but irreversible".

And that’s why, despite the prime minister’s natural instinct to inject his language with optimism, there’s been a concerted effort in recent months to manage our expectations.

For this pandemic has cruelly taught us, repeatedly, that the track back to normality will contain hairpins we haven’t yet seen.

And for every fleeting moment of feeling like we are getting there - it’s still another fortnight in England, at least, before it’s legal to go to the hairdressers.

The abnormal has become normal, but it’s worth reminding ourselves just how remarkable it still is.

We've heard that lorry drivers will be subject to a new testing regime if they come to England from outside the UK for more than two days.

Now it emerges that aircraft cabin crew, prison escorts and seasonal workers are also among those affected by the new rules.

From 6 April, people who stay in the country for 48 hours or more - but who are exempt from quarantine because of their job - will have to take a lateral flow test by the end of the second day.

Those remaining in the UK for any longer than 2 days will then be required to take a further test every 3 days - typically on days five and eight.

The tougher measures are to "ensure we keep track of any future coronavirus variants of concern", Grant Shapps wrote on Twitter. The new rules will primarily affect hauliers entering from Europe.

It's worth a quick re-cap of our top story this afternoon.

The government is "confident" everyone in the UK will get a second dose of the Covid vaccine within 12 weeks of their first, the culture secretary has said.

Oliver Dowden said "we always knew there would be ups and downs" but the timetable was on track.

He told the BBC's Andrew Marr it was "essential" to provide second doses and it would not require mixing vaccines.

Mr Dowden added that the Moderna jab was due to arrive in the UK in April.

New coronavirus variants that escape the protection offered by current vaccines are a "risk", and the answer is to vaccinate as many people as soon as possible, a leading immunologist has said.

Prof Robin Shattock, of Imperial College London, told BBC Radio 4's The World This Weekend that a rise in overall infection rates could "potentially knock us off course" as lockdown begins to ease.

"If we can keep [the rates] low, then hopefully cautiously we can go through these different stages of unlocking always remembering that we may need to turn back if we see a spike in cases," Shattock said.

New variants of the virus that make current jabs "less effective" mean ministers should take extra care when unlocking restrictions, he said.

He also described a second dose as being important for protection and that speeding these up could offer a better defence against new variants.

President Vladimir Putin has said he expects Russia to reach herd immunity by the end of the summer.

Speaking on television, the president said he was aiming to lift all coronavirus restrictions at the same time.

Mr Putin, who was vaccinated this week with a Russian-made vaccine, also said the only side effects he experienced post jab werea brief muscle ache and some discomfort at the site of the injection.

Last Monday the president revealed 6.3 million Russians had so far received one dose of a Covid vaccine - around 5% of Russia's adult population.

His target is to protect 60% of adults by July - sufficient for "collective immunity" to stop the virus spreading.

But that would require boosting the current vaccination rate from just a few thousand to more than 700,000 every day - and that's just a single dose of the vaccine, reports the BBC's Sarah Rainsford.

The daily count of deaths with coronavirus in Russia has reached 95,818 since the pandemic began - though the number of excess deaths recorded so far is some four times higher.

The UK's year of lockdowns has had a profound effect on crime and criminal justice.

From the first coronavirus fines for everyday activity, to sudden fluctuations in offences because of the impact of restrictions on our lives, these changes to community safety will have a lasting impact for years to come.

From fewer thefts in lockdown to a spike in recorded drug offences, the BBC's Dominic Casciani & Ben Butcher have taken a deeper look.

The Irish Government has said it is "not aware of any specific plans" by the UK to share its vaccine supply "at this stage".

It follows a story in the Sunday Times which reported the UK was planning to give 3.7 million vaccines to Ireland when it had spare capacity.

"The UK has previously indicated that once it has achieved a high level of vaccination of its own population, it would consider sharing vaccines with other countries," a spokesman for the Irish Government said on Sunday.

But added there were no "specific plans" currently.

"The Irish and UK governments maintain close contact across all matters of common interest."

Speaking on Sunday morning, Culture Secretary Oliver Dowden said there was no vaccine surplus at present.

"We clearly don't currently have a surplus of vaccines. Should we get to the point where we have a surplus of vaccines we'd make a decision on the allocation of that surplus."

"Our first priority is to deliver vaccines in the UK," he told Sky News' Sophy Ridge.

Earlier this month, the NHS warned of a significant reduction in jabs available in England in April, and there has been a delay to Oxford-AstraZeneca shipments from India.
