A viral immunologist answers key questions about the B16172 variant.
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.
A coronavirus variant with a double mutation has been found in the UK, with cases currently doubling every week.
Variants of the original SARS-CoV-2 are now in wide circulation. That means the third wave of COVID-19 has come with new questions about the variants, their effects and what might come next.
With changing recommendations about AstraZeneca's COVID-19 vaccine making headlines, many people have questions about its use.
The US lags in testing coronavirus samples from COVID-19 patients, which can help track the spread of the virus and the emergence of new variants. But labs are ramping up this crucial surveillance.
AstraZeneca just announced results from its US-based trial. It found the vaccine to be 79% effective and safe for use, despite recent concerns around reports of blood clots.
Moving Auckland to level 3 for a week gives health officials time to track down additional cases and shut off chains of transmission. But we should also be prepared for a wider outbreak.
The first year of dealing with the pandemic has taught New Zealand many lessons — including how we might tackle systemic social and environmental problems.
Are two face masks better than one? Adding layers of filtration by double masking is a way of using the masks that we already have, possibly to better effect.
These variants are definitely cause for concern. But there's every indication we can adapt our vaccine strategy to combat these and other variants going forward.
Recently announced travel restrictions are intended to curb the spread of COVID-19 variants. However, we need to do a better job of tracking arrivals into the country.
