Moderna CEO warns vaccine antibody levels could be up to EIGHT TIMES lower against Omicron variant and it may take 90 days before updated jab is available: Shares in firm soar 10%
Stephane Bancel told CNBC’s Squawk Box that his company is researching the variant and trying to determine how much of a risk it poses to Americans.
He fears that the antibodies Moderna’s COVID-19 vaccine provides to fight against the virus could be eight times lower against the new strain.
Die variant, which emerged last week, is believed to be the most infectious yet and could have the ability to evade vaccine protection.
While it has not yet been detected in the United States, health officials are on high alert and already preparing for it to cause yet another Covid surge in the nation.

The COVID-19 vaccines work by attacking the virus’s spike protein. Omicron is a rare strain that has more than 30 mutations of the protein, leading some experts to believe it can dodge vaccine protections.

‘There are two key things that we don’t know yet and will find out in [komende] weke],’ Bancel said.
‘One is vaccine efficacy. What is the impact of this new variant on the vaccine efficacy, and we should know that in around two weeks.’
Omicron was first discovered last week in South Africa, and is believed to have originated in nearby Botswana.
The variant was sequenced in at least 77 South Africans, and was also detected in those who had recently traveled out of the country.
‘We believe this [variant] is highly infectious… it seems to be much more infectious than Delta,’ Bancel said.
Not much is known about the variant yet, but experts are fearful that it can evade vaccines due to the number and type of mutations it has.
Unlike other variants, like Delta or Beta, the Omicron mutations are on the spike protein, the part of the virus the mRNA vaccines – like Moderna’s – target.
The variant also has over 30 mutations on the spike protein, a high amount when compared to other variants.
‘Given the large level of mutation it is highly possible that the efficacy of the vaccines, all of them, is going down,’ Bancel said.
He said it still take anywhere from two to six weeks for his company to really know how the vaccine interacts with the vaccines, wel.
Bancel also reports that his company could have an updated version of its Covid jab ready for Americans within the next 60 aan 90 days if it is determined to be needed.
Moderna is already testing a higher dose Covid booster – as the booster it received authorization for in recent weeks includes a smaller amount of the vaccine than the oringal two-shot regimen had.
It is also working on two separate booster candidates the company had previously designed fearing a vaccine resistant variant would form and an Omicron-specific booster shot is being fast-tracked.
Vir nou, wel, the world is stuck in a waiting game as health officials worldwide investigate the variant more.
Starting Monday, die VSA. will join a host of other nations banning incoming flights from seven African countries that are believed to be at risk.
Steeds, wel, the variant is already managing to spread around the world.
Botswana, South Africa and Hong Kong were the first nations to detect cases last week.
Quickly, many European countries like Austria, België, Tsjeggiese Republiek, Denemarke, Duitsland, Italië, Netherlands and Portugal all sequenced cases of the variant over the past few days.
Omicron cases were also detected in the United Kingdom over the weekend as well.
Op Sondag, the variant was first found in North America, when two cases were sequenced in Canada – a frightening prospect for the U.S.
Bancel believes that the variant has already spread across the world – even to places that instituted a travel ban – and will soon be detected almost everywhere.
‘We also believe it is already present in most countries,’ hy het gesê.
The emergence of Omicron has also led to an increased call for vaccine equity across the globe, as some believe new variants will be prevented with a more robust vaccine campaign worldwide.
In Afrika, where the variant was first detected, less than six percent of people have received at least one shot of a COVID-19 vaccine, and some countries have partially vaccinated less than two percent of people.
Bancel said Moderna is working on closing the vaccine gap, but it has run into some issues.
‘We have right now between 50-70 million doses of our vaccine in our warehouse ready to ship that have either customs issues or people in some countries have too many vaccines right now and not enough who want to get vaccinated,’ hy het gesê.
The Moderna vaccine is among the most used in the world, and only trails the Pfizer BioNTech vaccine in usage in America.

Vanaf Maandagoggend, die VSA. Centers for Disease Control and Prevention reports that the Moderna vaccine has been adminsitered 173 million times and fully vaccinated 71.5 miljoen mense.
Just under 70 percent of Americans have received at least one dose of a COVID-19 vaccines, en 59 persent is ten volle ingeënt.
Pfizer’s vaccine has been adminsitered 264 million times to fully vaccinated 108 miljoen mense, per the CDC data.
Albert Bourla, CEO of Pfizer, told Squawk Box that his company is acting quickly to respond to the threat posed by Omicron.
‘Friday we made our first DNA template which is the first part of the development process of a new vaccine,’ Het Bourla gesê.
‘We would be able to have a vaccine in less than 100 days.’
BioNTech, a German company partnering with Pfizer to develop and distribute the vaccine, reports that it will have more information of the variant – and how its vaccine will respond to it – within the next two weeks.
Why is Omicron so scary?
What is so concerning about the variant?
Experts say it is the ‘worst variant they have ever seen’ and are alarmed by the number of mutations it carries.
The variant — which the World Health Organization has named Omicron — has 32 mutations on the spike protein — the most ever recorded and twice as many as the currently dominant Delta strain.
Experts fear the changes could make the vaccines 40 per cent less effective in a best-case scenario.
This is because so many of the changes on B.1.1.529 are on the virus’s spike protein.
The current crop of vaccines trigger the body to recognise the version of the spike from older versions of the virus.
The Botswana variant has around 50 mutations and more than 30 of them are on the spike protein. The current crop of vaccines trigger the body to recognize the version of the spike protein from older versions of the virus. But the mutations may make the spike protein look so different that the body’s immune system struggles to recognize it and fight it off. And three of the spike mutations (H665Y, N679K, P681H) help it enter the body’s cells more easily. Intussen, it is missing a membrane protein (NSP6) which was seen in earlier iterations of the virus, which experts think could make it more infectious. And it has two mutations (R203K and G204R) that have been present in all variants of concern so far and have been linked with infectiousness
But because the spike protein looks so different on the new strain, the body’s immune system may struggle to recognise it and fight it off.
It also includes mutations found on the Delta variant that allow it to spread more easily.
Experts warn they won’t know how much more infectious the virus is for at least two weeks and may not know its impact on Covid hospitalizations and deaths for up to six weeks.
What mutations does the variant have?
The Botswana variant has more than 50 mutations and more than 30 of them are on the spike protein.
It carries mutations P681H and N679K which are ‘rarely seen together’ and could make it yet more jab resistant.
These two mutations, along with H655Y, may also make it easier for the virus to sneak into the body’s cells.
And the mutation N501Y may make the strain more transmissible and was previously seen on the Kent ‘Alpha’ variant and Beta among others.
Two other mutations (R203K and G204R) could make the virus more infectious, while a mutation that is missing from this variant (NSP6) could increase its transmissibility.
It also carries mutations K417N and E484A that are similar to those on the South African ‘Beta’ variant that made it better able to dodge vaccines.
But it also has the N440K, found on Delta, and S477N, on the New York variant — which was linked with a surge of cases in the state in March — that has been linked to antibody escape.
Other mutations it has include G446S, T478K, Q493K, G496S, Q498R and Y505H, although their significance is not yet clear.
Is it a variant of concern?
The World Health Organization has classified the virus as a ‘variant of concern’, the label given to the highest-risk strains.
This means WHO experts have concluded its mutations allow it to spread faster, cause more severe illness or hamper the protection from vaccines.
Where has the variant been detected so far?
The variant has so far been spotted in five nations: Suid-Afrika, Botswana, Hongkong, Israel and Belgium.
Most cases have been spotted in Gauteng, a province in north east South Africa where Johannesburg is based.
The first case was uploaded to international variant database GISAID by Hong Kong and was spotted in someone who travelled to the country from South Africa.
No cases have been seen in the UK. But scientists do not sequence every positive Covid sample in the UK and not everyone who catches the virus will take a test.
This means there could be people infected with the variant in Britain.
What is the UK doing about the variant?
The Health Secretary announced last night six countries would be added to the red list from midday on Friday November 26.
The red-listed countries are: Suid-Afrika, Botswana, In Swaziland, Lesotho, Namibia and Zimbabwe. This means all direct flights from these countries to the UK are banned.
Anyone arriving in England between midday today and 4am on Sunday from these countries — or who has been in the countries in the 10 previous days — must complete a passenger locator form, quarantine at home and should take a PCR test.
Anyone arriving from these countries after 4am on Sunday must stay in a managed quarantine hotel for 10 days and take a Covid test on or before the second day of their stay, as well as another test on or after day eight.
And the UK Health Security Agency classified B.1.1.529 as a Variant Under Investigation, which means it has worrying mutations.
Experts will now conduct a risk assessment and may increase its ranking to Variant of Concern if it is confirmed to be more infectious, cause more severe illness or make vaccines and medicines less effective.
Where did B.1.1.529 first emerge?
The first case was uploaded to international variant database GISAID by Hong Kong on November 23. The person carrying the new variant was traveling to the country from South Africa.
The UK was the first country to identify that the virus could be a threat and alerted other nations.
Sedertdien, 77 cases have been confirmed in South Africa, two in Hong Kong and three in Botswana.
Health chiefs in Israel today announced it had one confirmed and two suspected B.1.1.529 cases, while there are two suspected cases in Belgium.
Experts believe the strain may have originated in Botswana, but continental Africa does not sequence many positive samples, so it may never be known where the variant first emerged.
Professor Francois Balloux, 'n genetikus by University College London, told MailOnline the virus likely emerged in a lingering infection in an immunocompromised patient, possibly someone with undiagnosed AIDS.
In patients with weakened immune systems infections can linger for months because the body is unable to fight it off. This gives the virus time to acquire mutations that allow it to get around the body’s defenses.
Will I be protected if I have a booster?
Scientists have warned the new strain could make Covid vaccines 40 per cent less effective.
But they said emergence of the mutant variant makes it even more important to get a booster jab the minute people become eligible for one.
The vaccines trigger neutralizing antibodies, which is the best protection available against the new variant. So the more of these antibodies a person has the better, kenners gesê.
Britain’s Health Secretary, Sajid Javid, gesê: ‘The booster jab was already important before we knew about this variant – but now, it could not be more important.’
When will we know more about the variant?
Data on how transmissible the new variant is and its effect on hospitalizations and deaths is still weeks away.
The UK has offered help to South Africa, where most of the cases are concentrated, to gather this information and believe they will know more about transmissibility in two to three weeks.
But it may be four to six weeks until they know more about hospitalizations and deaths.
What is the variant called?
The strain was scientifically named as B.1.1.529 on November 24, one day after it was spotted in Hong Kong.
The variants given an official name so far include Alpha, Beta, Delta and Gamma.
Experts at the World Health Organization on November 26 named the variant Omicron.
