Hide AdWhat the Israeli government said about the Omicron variant
Health minister Nitzan Horowitz said today (1 December) that more data would be unveiled in the coming days but early signs were good.
He said: “In the coming days we will have more accurate information about the efficacy of the vaccine against Omicron.
“But there is already room for optimism, and there are initial indications that those who are vaccinated with a vaccine still valid or with a booster will also be protected from this variant.”

What preliminary data on Omicron reportedly found
Following Mr Horowitz’s comments, the Israeli broadcaster Channel 12 reported on preliminary data that South Africa had shared with countries from around the world.
The unconfirmed data reportedly showed that the Pfizer jab was 90% effective at preventing symptomatic infection from Omicron.

The report also suggested that the new variant is around 1.3 times more infectious than Delta, the Jerusalem Post reports.
People who have not been vaccinated have a 2.4 times greater chance of developing serious symptoms, the newspaper reported.

Hide AdWhat pharmaceutical companies have said about Omicron
There have been mixed messages from pharmaceutical companies over the risks posed by the Omicron variant.
BioNTech CEO and co-founder Ugur Sahin said: “We think it’s likely that people will have substantial protection against severe disease caused by Omicron.”
The University of Oxford added that there was no evidence that current vaccines would not protect people against severe symptoms from the new variants.

“I think it’s going to be a material drop. I just don’t know how much because we need to wait for the data. But all the scientists I’ve talked to... are like, ‘This is not going to be good.’”
What travel restrictions have been imposed over Omicron
