Australia seems to be focusing on boosters for people aged 75 and over, with its latest recommendations. But that may change.
The CDC expects the updated shots to be effective at preventing severe COVID-19, even in the face of new variants.

Only time and data will tell whether the CDC-recommended reformulated shots can stand their ground against the ever-changing SARS-CoV-2 variants.
BA.2.86 is beginning to spread throughout the United States.

Researchers still don’t know how well BA.2.86 will evade immunity or whether it will cause more severe disease than its predecessors.
How are people with long COVID faring two years after their initial infection? Many have recovered. Some still struggle with symptoms – this is more likely for those who were initially hospitalised.
As COVID finds its equilibrium, infection rates will rise and fall, influenced by seasons, school holidays and new subvariants. Managing the risk is complex and needs to be cost effective.
The Greek goddess Eris gave her name to the latest Omicron variant.
The World Health Organization has classified the EG.5 family of Omicron variants, including Eris, as ‘variants of interest’. What does that mean? And how does Eris differ to other Omicron variants?
Health workers who picked their noses were more likely to contract COVID, according to a new study. But here’s what the study means for the rest of us.
A new study published in Nature suggests a particular gene mutation could help explain why some people are asymptomatic. A virologist explains.

We studied 16 bat species in the UK to learn about the viruses they carry and understand the risk to humans.
Infection and vaccination both leave their mark in your blood.

There’s pretty much no one left in the US who hasn’t been exposed to the coronavirus, whether by vaccination, infection or both.
We know from other viruses that viral fragments can remain in different tissues for months or even years. This could be the case for long COVID.
About 10% of COVID-19 patients will experience continuing symptoms for 12 weeks or more following diagnosis.

There’s no one-size-fits-all approach for long COVID treatment, but exercise focusing on breathing and pacing yourself throughout the day often helps.
This variant seems to be causing a new symptom not commonly seen with earlier COVID strains.
Knowing if you have COVID or the flu can affect when you get vaccinated, need a particular antiviral, or if you need to work from home. But these combination tests can be expensive.
Certain immune cells acquired from a coronavirus that causes the common cold appear to react to COVID – but more so in children that adults.
Covid-19 exposed critical shortcomings of existing diagnostic techniques.

The pandemic spurred the diagnostics industry to consider aspects like scale, affordability, speed and portability of tests.
New reports suggest the pandemic’s origins may be linked to raccoon dogs sold at Wuhan’s Huanan Wholesale Seafood Market. A virologist explains.
Previous infection was highly protective against reinfection with alpha, beta and delta variants, but less so against omicron BA.1.
A team from the University of Tours and INRAE is working on the development of an innovative nasal vaccine against Covid, in spray form.
Vaccination is often combined with an injection. It can also take the form of a nasal spray: an approach that is still rare, but which could be effective against Covid. Here’s why.
Scientists are trying to find out whether there’s a genetic reason certain people have managed to avoid COVID for three years.
