One of the ways the Omicron variant is different from other variants is the sheer number of mutations in the spike protein. Does this make it a super-variant?

At this stage, we cannot say anything about the severity of cases with Omicron - either in primary or reinfections.
The participation of five-to-11-year-old children in vaccination programs will make 90 per cent of the population eligible to get vaccinated against COVID-19.
Careful lab work will complement public health data as researchers worldwide focus on omicron, asking questions about contagiousness, severity of disease and whether vaccines hold up against it.
Omicron may soon arrive at the border, but New Zealand hopes to keep it out of the community through border controls, testing requirements and rapid genome sequencing of any positive cases.
The new omicron variant of coronavirus has a number of mutations that may require manufacturers to update vaccines. The unique attributes of mRNA vaccines make updating them fast and easy.
Just when things seemed to be getting back to COVID normal, a new variant has us worried all over again. But we can be kind to our brains and boost well-being in uncertain times.
It’s too early to say whether the newly identified omicron variant is going to overtake delta. But particular mutations in the new strain have researchers deeply concerned.
