Achieving widespread immunity to COVID-19 through vaccination requires as many people as possible to get their shots, including those who object or haven’t bothered.
A 2015 paper on chicken virus evolution is being taken out of context and used to fuel fears about COVID-19 vaccines. Its lead author aims to clarify the science in hopes of saving lives.
It has been six months since the Johnson & Johnson vaccine received emergency use authorization. What does six months of data show about its efficacy, side effects and protection from variants?
People who had previously caught the coronavirus, which is similar to having an additional vaccine dose, had more neutralising antibodies against COVID variants after being vaccinated.
‘Contracting out’ government functions for delivery by the private sector has become the standard way of doing things across all levels of government in Australia.
The U.S. FDA has approved the first COVID-19 vaccine. How is approval different from emergency use authorization, and what difference will it make to a vaccine that’s already in global use?
Since the WHO’s investigation earlier this year, several papers have come to the same conclusion regarding the likely origins of SARS-CoV-2. Yet progress is too slow.
While there are plausible explanations for why this occurs, we can’t be certain of the effect of temperature on SARS-CoV-2. Being indoors in poorly ventilated spaces plays a big role.
Another wave of COVID-19 in Russia is undermining public health and threatens economic recovery. But widespread mistrust of institutions will stymie the country’s efforts to move past the pandemic.
Nurses and healthcare workers will need more support in the longer term to deal with the considerable effect COVID-19 has had on mental health and wellbeing.
Anti-vaccine activists are using the side effect reporting system to spread fear and misinformation about the COVID-19 vaccines. But the database could also be used as a gauge for public concerns.
Governments cannot keep making unrealistic promises about easing restrictions at 70% and 80% adult vaccination, a plan that relied on optimistic scenarios in the first place.
