For a number of reasons, as time goes on vaccines become less effective. So how do researchers calculate how well vaccines are working?
The revolt over new restrictions comes in stark contrast to support of other draconian laws.
In places with low vaccination rates, COVID-19 has the chance to linger, and variants develop and travel. Without global vaccine equity, this entirely predictable pattern will repeat itself.
A third vaccine dose raises protection against omicron to 75%, early data suggests.
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.
