Another year, another COVID wave. Here’s what we know about what the virus is doing around the country.
As the virus continues to mutate, COVID vaccines are updated. This brings us to the latest announcement about the new ‘monovalent’ vaccines.
COVID-19 remains a global public health threat despite its current non-pandemic status.
Researchers still don’t know how well BA.2.86 will evade immunity or whether it will cause more severe disease than its predecessors.
With the emergency phase of the COVID-19 pandemic in the rearview mirror, at least for now, we look back on a handful of stories that provided sharp insights at key moments in the pandemic.
This variant seems to be causing a new symptom not commonly seen with earlier COVID strains.
XBB.1.5 and other subvariants do signal a change in how the virus is mutating. Here’s what this means for Australia and globally.
Many questions remain about next steps for US vaccine policy. But the FDA advisory panel’s hearty endorsement of a single-composition COVID-19 vaccine represents a pivotal step.
Data suggests the bivalent boosters are working well against omicron.
After a year of omicron variants, will we ever see a new variant of concern?
Reports from China indicate BF.7 is quicker to transmit and has greater capacity to escape prior immunity than other omicron subvariants. But we shouldn’t be alarmed at this stage.
New Zealand’s proportion of reinfections is now at 17% of new cases. As new variants continue to proliferate, vaccine boosters would protect those most vulnerable and reduce the risk of long COVID.
Case numbers are falling in all age groups, including over-70s. This is good news as case rates in older people have been a key driver of the steep rise in hospitalisations and deaths in this wave.
We published an article earlier this month that contained incorrect estimates for the basic reproduction number (R0) for COVID subvariants BA.4/BA.5 and BA.2. We have now corrected the error, but I wanted…
