Vaccine manufacturers have expressed confidence that they will be able to rapidly adapt their jabs if the Omicron variant spreads.
The new strain – previously known as B.1.1.529 – features some “concerning” mutations, and early evidence suggests it brings an increased risk of reinfection.
There are also fears that the variant could be more resistant to the vaccines that have now been rolled out to billions of people around the world.

If this is the case, Pfizer and BioNTech expects “to be able to develop and produce a tailor-made vaccine against that variant in approximately 100 days, subject to regulatory approval”.
Moderna said it has advanced a “comprehensive strategy to anticipate new variants of concern” since early 2021 – including three levels of response if the immunity offered by its jabs wanes.

Novavax added it has already started creating a COVID-19 vaccine based on the known genetic sequence of B.1.1.529 “and will have it ready to begin testing and manufacturing within the next few weeks”.
Yesterday, the World Health Organisation designated B.1.1.529 as a “variant of concern”, meaning it has now officially been given the name Omicron, a letter from the Greek alphabet.

Although no infections linked to the Omicron variant have been detected in the UK or the US so far, there has been a case in Belgium involving an unvaccinated person who had travelled abroad.
Salim Abdool Karim, one of South Africa’s top epidemiologists, told Sky News he “would expect it to be in the UK” by now.
Health Secretary Sajid Javid has warned that there is a “possibility it might have a different impact on individuals” who get coronavirus.
However, he stressed the UK remains in a “strong position” due to the high vaccination take-up – adding that Omicron’s presence means getting a booster jab is even more important now.
British scientists first became aware of the new strain on 23 November after samples were uploaded on to a COVID variant tracking website from South Africa, Hong Kong and then Botswana. A total of 59 samples have been uploaded so far.
Amid the concerns, flights to the UK from South Africa and five other southern African countries – Namibia, Lesotho, Botswana, Eswatini and Zimbabwe – have been suspended until 4am on Sunday.

‘Huge international concern’ over variant
These nations have now been added to the red list, and from Sunday, British nationals returning from these destinations will be required to quarantine in government-approved hotels for 10 days.
Mr Javid confirmed the government is still following Plan A for managing COVID-19 this autumn and winter but warned “if we need to go further, we will”.
England’s chief medical officer, Professor Chris Whitty, has said his “greatest worry” is whether the public would accept fresh restrictions if they were required.
In the long Gaza war, this is a significant moment.
For the people of Gaza, for the hostages and their families – this could be the moment it ends. But we have been here before, so many times.
The key question – will Hamas accept what Israel has agreed to: a 60-day ceasefire?
At the weekend, a source at the heart of the negotiations told me: “Both Hamas and Israel are refusing to budge from their position – Hamas wants the ceasefire to last until a permanent agreement is reached. Israel is opposed to this. At this point only President Trump can break this deadlock.”
The source added: “Unless Trump pushes, we are in a stalemate.”
The problem is that the announcement made now by Donald Trump – which is his social-media-summarised version of whatever Israel has actually agreed to – may just amount to Israel’s already-established position.
We don’t know the details and conditions attached to Israel’s proposals.
Would Israeli troops withdraw from Gaza? Totally? Or partially? How many Palestinian prisoners would they agree to release from Israel’s jails? And why only 60 days? Why not a total ceasefire? What are they asking of Hamas in return? We just don’t know the answers to any of these questions, except one.
We do know why Israel wants a 60-day ceasefire, not a permanent one. It’s all about domestic politics.
If Israeli Prime Minister Benjamin Netanyahu was to agree now to a permanent ceasefire, the extreme right-wingers in his coalition would collapse his government.
Itamar Ben-Gvir and Bezalel Smotrich have both been clear about their desire for the war to continue. They hold the balance of power in Mr Netanyahu’s coalition.
If Mr Netanyahu instead agrees to just 60 days – which domestically he can sell as just a pause – then that may placate the extreme right-wingers for a few weeks until the Israeli parliament, the Knesset, is adjourned for the summer.
It is also no coincidence that the US president has called for Mr Netanyahu’s corruption trial to be scrapped.
Without the prospect of jail, Mr Netanyahu might be more willing to quit the war safe in the knowledge that focus will not shift immediately to his own political and legal vulnerability.
The Women’s Euros begin in Switzerland today – with extreme heat warnings in place.
Security measures have had to be relaxed by UEFA for the opening matches so fans can bring in water bottles.
Temperatures could be about 30C (86F) when the Swiss hosts open their campaign against Norway in Basel this evening.
Players have already seen the impact of heatwaves this summer at the men’s Club World Cup in the US.

It is raising new concerns in the global players’ union about whether the stars of the sport are being protected in hot and humid conditions.
FIFPRO has asked FIFA to allow cooling breaks every 15 minutes rather than just in the 30th minute of each half.
There’s also a request for half-time to be extended from 15 to 20 minutes to help lower the core temperature of players.

FIFPRO’s medical director, Dr Vincent Gouttebarge, said: “There are some very challenging weather conditions that we anticipated a couple of weeks ago already, that was already communicated to FIFA.
“And I think the past few weeks were confirmation of all worries that the heat conditions will play a negative role for the performance and the health of the players.”
Football has seemed focused on players and fans baking in the Middle East – but scorching summers in Europe and the US are becoming increasingly problematic for sport.

Wildfires erupt in Italy and France amid heatwave
FIFA said in a statement to Sky News: “Heat conditions are a serious topic that affect football globally.
“At the FCWC some significant and progressive measures are being taken to protect the players from the heat. For instance, cooling breaks were implemented in 31 out of 54 matches so far.
“Discussions on how to deal with heat conditions need to take place collectively and FIFA stands ready to facilitate this dialogue, including through the Task Force on Player Welfare, and to receive constructive input from all stakeholders on how to further enhance heat management.
“In all of this, the protection of players must be at the centre.”
Around 14 million people could die across the world over the next five years because of cuts to the US Agency for International Development (USAID), researchers have warned.
Children under five are expected to make up around a third (4.5 million) of the mortalities, according to a study published in The Lancet medical journal.
Estimates showed that “unless the abrupt funding cuts announced and implemented in the first half of 2025 are reversed, a staggering number of avoidable deaths could occur by 2030”.
“Beyond causing millions of avoidable deaths – particularly among the most vulnerable – these cuts risk reversing decades of progress in health and socioeconomic development in LMICs [low and middle-income countries],” the report said.

March: ‘We are going to lose children’: Fears over USAID cuts in Kenya
USAID programmes have prevented the deaths of more than 91 million people, around a third of them among children, the study suggests.
The agency’s work has been linked to a 65% fall in deaths from HIV/AIDS, or 25.5 million people.
Eight million deaths from malaria, more than half the total, around 11 million from diarrheal diseases and nearly five million from tuberculosis (TB), have also been prevented.
USAID has been vital in improving global health, “especially in LMICs, particularly African nations,” according to the report.

Queer HIV activist on Trump and Musk’s USAID cuts
Established in 1961, the agency was tasked with providing humanitarian assistance and helping economic growth in developing countries, especially those deemed strategic to Washington.
But the Trump administration has made little secret of its antipathy towards the agency, which became an early victim of cuts carried out by the Department of Government Efficiency (DOGE) – formerly led by Elon Musk – in what the US government said was part of a broader plan to remove wasteful spending.

What is USAID?
In March, US Secretary of State Marco Rubio said more than 80% of USAID schemes had been closed following a six-week review, leaving around 1,000 active.
The US is the world’s largest humanitarian aid donor, providing around $61bn (£44bn) in foreign assistance last year, according to government data, or at least 38% of the total, and USAID is the world’s leading donor for humanitarian and development aid, the report said.
Between 2017 and 2020, the agency responded to more than 240 natural disasters and crises worldwide – and in 2016 it sent food assistance to more than 53 million people across 47 countries.
The study assessed all-age and all-cause mortality rates in 133 countries and territories, including all those classified as low and middle-income, supported by USAID from 2001 to 2021.
