A new trial has begun in Victoria this week to evaluate a potential vaccine against COVID-19.
The vaccine is called NVX-CoV2373 and is from a US biotech company, Novavax.
The trial will be carried out across Melbourne and Brisbane, and is the first human trial of a vaccine specifically for COVID-19 to take place in Australia.
This vaccine is actually based on a vaccine that was already in development for influenza. But how might it work against SARS-CoV-2, the coronavirus that causes COVID-19?
