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?
It was the biases of its ‘first world’ which prevented South Africa from mobilising the energies and talents of most of its people against COVID-19.
Early data show that Omicron is dominating new COVID-19 cases in Gauteng province.
At this stage, we cannot say anything about the severity of cases with Omicron - either in primary or reinfections.
Antibodies in people’s blood seem much less able to neutralise the new variant – but these new findings should be treated with caution.
Knowing when and how often to use rapid tests is key to getting an accurate picture of your COVID-19 status.
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.
If it’s been six months since your second COVID vaccine dose, it’s time to book in for your booster. Here’s why.
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.
Efforts to improve vaccine uptake must be tailored to the needs and concerns of the individuals and families who make up society.
Austria and Greece have introduced vaccine mandates, and Germany is considering it.
How we should manage uncertainty is not a scientific issue but an ethical issue.
Michelle Grattan discusses the political week that was with Vice-Chancellor Paddy Nixon.
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.
We won’t know whether Omicron evades COVID vaccines for another few weeks. Here’s why.
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.
Word from The Hill: Politicians condemn bad behaviour, and then behave badly
