UK research has revealed more about the new Omicron variant

Omicron largely evades immunity from past coronavirus infection or two vaccine doses, and boosters are key to mitigating the impact of the variant, new research suggests.

The risk of reinfection with Omicron is 5.4 times greater than that of the Delta variant, according to researchers at Imperial College London.
