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.
Donald Trump has agreed to send “top of the line weapons” to NATO to support Ukraine – and threatened Russia with “severe” tariffs if it doesn’t agree to end the war.
Speaking with NATO secretary general Mark Rutte during a meeting at the White House, the US president said: “We’ve made a deal today where we are going to be sending them weapons, and they’re going to be paying for them.
“This is billions of dollars worth of military equipment which is going to be purchased from the United States,” he added, “going to NATO, and that’s going to be quickly distributed to the battlefield.”
Weapons being sent include surface-to-air Patriot missile systems and batteries, which Ukrainehas asked for to defend itself from Russian air strikes.

Mr Trump also said he was “very unhappy” with Russia, and threatened “severe tariffs” of “about 100%” if there isn’t a deal to end the war in Ukraine within 50 days.
The White House added that the US would put “secondary sanctions” on countries that buy oil from Russia if an agreement was not reached.
It comes after weeks of frustration from Mr Trump against Vladimir Putin’s refusal to agree to an end to the conflict, with the Russian leader telling the US president he would “not back down”from Moscow’s goals in Ukraine at the start of the month.

Trump says Putin ‘talks nice and then bombs everybody’
During the briefing on Monday, Mr Trump said he had held calls with Mr Putin where he would think “that was a nice phone call,” but then “missiles are launched into Kyiv or some other city, and that happens three or four times”.
“I don’t want to say he’s an assassin, but he’s a tough guy,” he added.
After Mr Trump’s briefing, Russian senator Konstantin Kosachev said on Telegram: “If this is all that Trump had in mind to say about Ukraine today, then all the steam has gone out.”
Meanwhile, Mr Zelenskyy met with US special envoy Keith Kellogg in Kyiv, where they “discussed the path to peace” by “strengthening Ukraine’s air defence, joint production, and procurement of defence weapons in collaboration with Europe”.
He thanked both the envoy for the visit and Mr Trump “for the important signals of support and the positive decisions for both our countries”.
At least 30 people have been killed in the Syrian city of Sweida in clashes between local military groups and tribes, according to Syria’s interior ministry.
Officials say initial figures suggest around 100 people have also been injured in the city, where the Druze faith is one of the major religious groups.
The interior ministry said its forces will directly intervene to resolve the conflict, which the Reuters news agency said involved fighting between Druze gunmen and Bedouin Sunni tribes.
It marks the latest episode of sectarian violence in Syria, where fears among minority groups have increased since Islamist-led rebels toppled President Bashar al Assad in December, installing their own government and security forces.

In March, Sky’s Stuart Ramsay described escalating violence within Syria
The violence reportedly erupted after a wave of kidnappings, including the abduction of a Druze merchant on Friday on the highway linking Damascus to Sweida.
Last April, Sunni militia clashed with armed Druze residents of Jaramana, southeast of Damascus, and fighting later spread to another district near the capital.
But this is the first time the fighting has been reported inside the city of Sweida itself, the provincial capital of the mostly Druze province.
The Syrian Observatory for Human Rights (SOHR) reports the fighting was centred in the Maqwas neighbourhood east of Sweida and villages on the western and northern outskirts of the city.
It adds that Syria’s Ministry of Defence has deployed military convoys to the area.
Western nations, including the US and UK, have been increasingly moving towards normalising relations with Syria.

Concerns among minority groups have intensified following the killing of hundreds of Alawites in March, in apparent retaliation for an earlier attack carried out by Assad loyalists.
That was the deadliest sectarian flare-up in years in Syria, where a 14-year civil war ended with Assad fleeing to Russia after his government was overthrown by rebel forces.
The city of Sweida is in southern Syria, about 24 miles (38km) north of the border with Jordan.
The man convicted of the murder of British student Meredith Kercher has been charged with sexual assault against an ex-girlfriend.
Rudy Guede, 38, was the only person who was definitively convicted of the murder of 21-year-old Ms Kercher in Perugia, Italy, back in 2007.
He will be standing trial again in November after an ex-girlfriend filed a police report in the summer of 2023 accusing Guede of mistreatment, personal injury and sexual violence.
Guede, from the Ivory Coast, was released from prison for the murder of Leeds University student Ms Kercher in 2021, after having served about 13 years of a 16-year sentence.

Since last year – when this investigation was still ongoing – Guede has been under a “special surveillance” regime, Sky News understands, meaning he was banned from having any contact with the woman behind the sexual assault allegations, including via social media, and had to inform police any time he left his city of residence, Viterbo, as ruled by a Rome court.
Guede has been serving a restraining order and fitted with an electronic ankle tag.
The Kercher murder case, in the university city of Perugia, was the subject of international attention.
Ms Kercher, a 21-year-old British exchange student, was found murdered in the flat she shared with her American roommate, Amanda Knox.
The Briton’s throat had been cut and she had been stabbed 47 times.

Ms Knox and her then-boyfriend, Raffaele Sollecito, were placed under suspicion.
Both were initially convicted of murder, but Italy’s highest court overturned their convictions, acquitting them in 2015.
