“Omicron has been detected in all nations the place we now have good sequencing and it is prone to be in all nations world wide. It’s rapidly, when it comes to its circulation, overtaking Delta. And so Omicron is changing into the dominant variant that’s being detected,” Kerkhove mentioned throughout a digital questions and solutions session.

She additional cautioned that though there’s some info that Omicron causes much less extreme illness than Delta, “it isn’t a gentle illness” as a result of “persons are nonetheless being hospitalized for Omicron.”

The replace additionally famous that since December, six research have offered proof of diminished vaccine effectiveness (VE) of COVID-19 vaccines towards the Omicron variant.

“Whereas early VE estimates towards the Omicron variant needs to be interpreted with warning as a result of potential biases, these preliminary outcomes present proof of diminished total effectiveness of vaccines towards the Omicron variant, with higher declines in effectiveness with rising time since vaccination, relative to Delta… Whereas a booster vaccination seems to enhance VE towards an infection and hospitalisation as a result of Omicron variant, extra knowledge are wanted to assess each the magnitude and period of the safety,” the replace mentioned.

The WHO Technical Advisory Group on COVID-19 Vaccine Composition (TAG-CO-VAC) mentioned that as coronavirus evolves, the composition of present COVID-19 vaccines might should be up to date, to make sure that “COVID-19 vaccines proceed to offer WHO-recommended ranges of safety towards an infection and illness by VOCs, together with Omicron and future variants.”

Kerkhove added that as Omicron enters and circulates amongst weak populations, “we are going to see a rise in hospitalisations and deaths. So please deal with this virus as critically because it must be handled. The narrative that it is the widespread chilly isn’t true. The narrative that it’s simply delicate isn’t true.
