Several of the Sunday papers report on Covid vaccination plans - and the Telegraph's headline is: "All over-18s could have jab by end of June".
Ministers, it reports, are "increasingly optimistic" that they will be able to meet this target, as the distribution of coronavirus vaccines speeds up.
Whitehall sources tell the paper that the government is looking at inoculating between 4 and 5 million people each week within months.
But the paper says that - while this is what ministers are privately aiming for - officials at the Department of Health are "reluctant to publicly acknowledge a deadline".
The Sunday Mirror accepts that the UK is doing better than many countries in rolling out the vaccines - but it thinks that "better does not mean good enough".
Its leader points out that frontline health workers face a much greater risk than most people of catching Covid-19 - and argues that they should not have to wait three months for the second booster jab.
It also believes that teachers, police and firefighters should be vaccinated as soon as possible.
"Brits are fed up to the back teeth with Covidiots breaking the rules", laments the Sun on Sunday.
More than half of the people questioned in a YouGov poll for the paper felt the police were not being tough enough on those flouting lockdown measures.
Its opinion column states that "with the NHS at breaking point, the public is in no mood to tolerate anyone who plays with the nation's health".
There are details in the Sunday Times of how England rugby star Maro Itoje is trying to give disadvantaged pupils access to laptops, so they can get the most out of home schooling.
It describes how the player - who is known by fans as "Super Maro" - has been inspired by the free school meals campaign led by the footballer, Marcus Rashford.
Itoje tells the paper: "The absolute priority right now is guaranteeing children have devices to learn."
The Mail on Sunday reports that British billionaire Sir Jim Ratcliffe is facing a "revolt" by farmers in Iceland - because he has bought "large tracts of the country's pristine wilderness", in order to secure fishing rights to rivers there.
It says Sir Jim, the founder of the Ineos chemicals group, has spent more than £36m buying farms, as part of his project to conserve North Atlantic salmon.
The Mail reports that his lack of connection to Icelandic communities has led to concern about future use of the land.
But a spokesman for an angling club run by Sir Jim tells the paper that suspicions about his motives are "ludicrous", and his sole mission is conservation.
'King of K2'
Finally, several of the front pages feature the same photo of Nirmal Purja, the former Gurkha who led a team of Nepalese Sherpas to the first successful winter ascent of the K2 peak.
He is pictured at altitude in his mountaineering gear, gazing into the distance with an enigmatic smile.
The Observer's headline is: "King of K2". It suggests the achievement marks the end of climbing as "an imperialist and colonialist enterprise" - when the Sherpas were the backbone of expeditions, but received none of the glory or benefits.
