We are no strangers to Omicron, the latest variant of the virus that causes COVID. But until recently, our vaccines haven’t caught up with the rapidly mutating SARS-CoV-2.
That’s about to change with the recent approval of an Omicron-specific vaccine, set to be used in Australia as a booster shot for adults. It’s already been approved in the United Kingdom and the United States.
Which Australians will get the new booster and when is unclear. But the booster, made by Moderna, is expected to protect against currently circulating versions of the virus, and possibly future ones. Pfizer also has an Omicron booster, which has been approved in the US.
Our COVID vaccines are also changing in other ways. Researchers are working on vaccines to be delivered as a patch or via the nose, as well as formulations that are more stable at room temperature or which provide better protection at the tiniest of doses, although not all of the 120 or so potential COVID vaccines in development will make it through clinical trials.
Paul Griffin from the University of Queensland is the lead investigator on several COVID vaccine studies. Today, he explains what to expect from the next generation of vaccines.
