To help people make informed decisions about ongoing COVID-19 risks, public health messaging needs to adapt as the pandemic evolves, just as immune systems adapt to new viruses and variants.
We modelled the impact small reductions in transmission would have on COVID deaths. We found a 20% drop could save the lives of 500 Victorians this year, or 2,000 people nationally.

Public health measures to curb the spread of COVID-19 require face masks in many settings.

The court appears split over the future of vaccination mandates, with conservative justices skeptical of the Biden administration’s authority to enforce requirements.
In Africa, it’s more rational to prioritise vaccine access, rapid rollout and community engagement, than pushing the narrative of vaccine-induced population immunity.
Different groups of researchers give different predictions. And it’s easy to be bewildered, especially if you’re in lockdown and looking for answers. Here’s what to make of it all.
If we open up the international borders before enough of the population is vaccinated, hospitals could become overwhelmed and deaths would be unacceptably high.
