There are several earlier examples of people studying infectious pathogens being infected in the laboratory, even while working under strict biosafety conditions.

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.
Scientists have discovered that SARS-CoV-2 can evade neutralising antibodies by fusing cells.
Both the AstraZeneca and Pfizer vaccines still work relatively well against it — though only after the second dose.
Gain-of-function studies make a natural virus more dangerous or transmissible to humans. Could the Wuhan Institute of Virology be the source of SARS-CoV-2?
We have the chance to build a world class, dedicated quarantine facility. Here’s how we could do it.
Chance matters. It’s unlikely Victoria is doing anything that ‘makes us’ more likely to have outbreaks leading to lockdowns.
The lab accident theory of the origins of Covid-19 has gained traction in recent months. We need a proper investigation to find out what really happened.
A more coordinated effort by scientists, stakeholders and community members will be required to stop the next deadly virus that’s already circulating in our midst.
This treatment would work by targeting the SARS-CoV-2 virus itself and stopping it in its tracks. The evidence we have so far is promising, but it’s still very early days.
It’s an absolute priority we find and use ways to support kids to continue face-to-face learning in times of low community transmission, especially primary schools.
Viruses want to pass on their genetic material. Recognizing this about SARS-CoV-2 provides insight into how the world is still vulnerable to COVID-19.
The COVID-19 vaccines are a smash success. But that doesn’t mean they keep every vaccinated person completely free of the coronavirus.
Deficient leptin levels caused by malnutrition might protect against severe COVID-19 and related death. This could be another reason for the lower than expected COVID-19 deaths in Africa.
You only have to prevent one case, which could have otherwise led to community spread and lockdown, for such a scheme to pay for itself many times over.
Entertainment, sports and tourism industries can learn valuable lessons from how Saudi Arabia managed the annual pilgrimage during a pandemic.
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.
By merging genomics with classical epidemiology, researchers are able to predict new disease outbreaks based on which viral variants are on the rise.
It’s quite likely this virus will never be eliminated from the world. But even so, getting vaccinated enormously reduces your risk of severe outcomes like hospitalisation and death.
