This guidance replaces previous conditional recommendations for the use of these drugs and is based on emerging evidence that they’re not likely to work against omicron.

BA.4.6 seems to be even better at evading our immune response than BA.5.
Early on, public health messaging focused on the need for vaccines to combat COVID-19. But far less attention has been given to the role of boosters in preventing deaths and reducing inequities.
The UK has become the first country to approve the shot, which targets omicron alongside the original strain of SARS-CoV-2.
Just because a variant spreads faster, it doesn’t necessarily mean it has a higher R0.
Face masks are still an effective way to help stop the spread of the BA.5 subvariant.
The last Omicron wave affected younger people. But the new BA.5 variant is seeing case numbers in older age groups higher than ever before – just as hospitals are under the most pressure.
Is it time for a new generation of COVID vaccines? Here’s where the research is at.
Achieving herd immunity via vaccination was always going to be a hard ask. Now it’s mathematically impossible.
Understanding the depth of vaccine hesitancy, and the drivers behind the lack of take-up is critical to preventing further deaths, infections, and continuing harm to the economy.
The COVID isolation period is seven days in Australia, but you might still be infectious after that if you have symptoms and a positive RAT.
The COVID-19 vaccines continue to be effective against severe illness leading to hospitalization and death in all age groups, including children ages 5 to 11.
What’s the difference between a variant and a subvariant? It’s all in the behaviour.
At this stage of the pandemic complacency is likely to lead to an increase in cases, hospitalisation, morbidity and mortality.
Repeated resurgences of SARS-CoV-2 transmission are expected in the years to come.
After reporting zero COVID cases until now, North Korea is facing a rapidly-spreading outbreak of the omicron variant. Here’s how things could play out.
With the relaxation of mask-wearing mandates, there’s even more need to know how much over-the-counter tests help.
It’s hard to keep up. But new Omicron sub-variants are emerging that may lead to reinfections and another spike in cases.
‘Living with COVID-19’ has much higher risks for Nunatsiavut Inuit communities than many other areas. Recognizing those risks is crucial as mining operations resume in Newfoundland and Labrador.
Instead of minimizing current or future waves of COVID-19, we need strategies to deal with new variants efficiently. Only then can we live with the virus in a healthy way.
