As Australia joins the worldwide Covid-19 vaccine rollout, researchers keep emphasising that while we know the various vaccines in use are strong at preventing hospitalisation and severe disease, it’s less clear how well they stop the virus spreading to other people.
While the term ‘Covid-19’ is often used interchangeably to describe both the virus and the disease, it is important to understand the distinction between the two.
The virus is Sars-CoV-2, while the disease that can cause symptoms such as coughing and fever is Covid-19. We know vaccinated people are protected in 63-95% of cases from developing Covid-19 and its symptoms, depending on the vaccine. All of the vaccines being rolled out are similarly highly effective at stopping severe disease.

“The implications of vaccine rollouts for border measures is something that is still being considered and it is too soon to know exactly how these will interact with each other,” said Hipkins. “But both Australia and New Zealand are actively pursuing vaccination purchase and rollout strategies and we are in close contact with each other as these progress.”
But it is considered unlikely that at least the first generation of the vaccine will prevent transmission of coronavirus, with a review commissioned by the Australian Academy of Health and Medical Sciences finding that public health measures and management would remain crucial this year.
