European organization says there is a high risk that the new Omicron variant will spread in Europe

"There is considerable uncertainty related to the transmissibility, vaccine effectiveness, risk for reinfections and other properties of the Omicron variant. However, given its immune escape potential and potentially increased transmissibility advantage compared to Delta, we assess the probability of further introduction and community spread in the EU/EEA as HIGH. In a situation where the Delta variant is resurgent in the EU/EEA, the impact of the introduction and possible further spread of Omicron could be VERY HIGH. In conclusion, the overall level of risk for the EU/EEA associated with the SARS-CoV-2 variant Omicron is assessed as HIGH to VERY HIGH," the ECDC said.
