The Omikron variant has held the top position among coronaviruses for a relatively long time. Strictly speaking, this is not a single variant, but a whole soup of Omikron sub-variants that constantly alternate at the top position. Currently, one variant is increasingly prevailing over the others - namely BQ.1.1.
In social media, BQ.1.1 has been nicknamed "Cerberus" - that is the three-headed hellhound from Greek mythology. Does the new variant really live up to its top name? What do we know about its spread and possible severity of progression? And how well do current COVID-19 vaccines protect us?
Molecular biologist Martin Moder takes aim at the "hellhound" variant. In this video, he gives a virus variant update and looks at what's up with the new, emerging omicron sub-variant BQ.1.1.
