The Delta variant: What it is, where it came from, why it's different and whether COVID-19 vaccines can prevent it.
We recently heard reports of a new and dangerous 'hybrid' variant circulating in Vietnam. There is such as a thing as a hybrid viral variant — but this doesn't appear to be it.
It is unlikely that we will reach full herd immunity for COVID-19. However, we are likely to reach a practical kind of herd immunity through vaccination.
Bat hosts, lab leaks – tracing SARS-CoV-2 to its origins involves more than just tracking down patient zero.
Both the AstraZeneca and Pfizer vaccines still work relatively well against it — though only after the second dose.
The World Health Organization has created more memorable and less stigmatising names for coronavirus variants.
The COVID-19 variant responsible for Victoria's latest outbreak is one of three Indian variant sub-types, which spreads more easily than the original strain. Here's what we know so far.
One of the main fears regarding new SARS-CoV-2 variants is that they might be resistant to immunity granted by vaccines, including RNA vaccines.
Variants of interest and variants of concern seem to be popping up at an alarming rate. But how many of them do we really need to worry about?
What does the Seychelles experience tell us about variants, vaccine efficacy and herd immunity?
As the Indian variant becomes more prevalent within our borders, anti-South Asian sentiment is also growing, putting the community at a higher risk of hate crimes.
A viral immunologist answers key questions about the B16172 variant.
There's still a lot we don't know about the latest variant of concern: B16172.
Despite some public virtue signalling, the Canadian government is not doing all it can to improve global access to COVID-19 vaccines. Canada has yet to announce its position on the WTO patent waiver.
Vaccination is likely to substantially reduce virus transmission by reducing the pool of people who become infected, and reducing virus levels in people who do get infected.
It sounds too good to be true, a vaccine that can protect against future virus variants. But governments around the world are keen to learn more.
Coronavirus is 30,000 RNA 'letters' long, meaning there are over a quintillion possible genome permutations.
By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.
Pressure is mounting to get COVID vaccines to where they are most needed.
The emergence of an Indian "double mutant" strain of the coronavirus may explain the country's tragically soaring infection rates. Genomic testing and monitoring will be crucial in the weeks ahead.
