There are two new COVID-19 vaccines that appear to be more than 90% effective. But what are these vaccines, and how are they different from those used previously?
Two more COVID-19 vaccines may now be on the cards for Australia, should they pass clinical trials. But, as with earlier vaccine deals, there are no guarantees.
So-called mRNA vaccines are among the frontrunners in the global race to design a COVID vaccine. But as a new technology, most nations, including Australia, lack the capacity to produce them at scale.
