What are the dominant coronavirus traces in Australia?
With an anticipated build up in COVID-19 instances this wintry weather, Australians’ choices for COVID jabs are restricted to Pfizer’s XBB.1.5 and BA.4/5 vaccine or Moderna’s XBB.1.5 vaccine.

How does the Novavax vaccine paintings?
When Novavax used to be offered to Australia it , as this can be a extra conventional protein-based vaccine.
It differs from mRNA vaccines in that it delivers the spike protein immediately into our frame, instead than teaching our cells to form it, Adrian Esterman, chair of epidemiology on the College of South Australia, informed SBS Information.
“The spike protein itself is made using moth cells in a laboratory, and then an adjuvant is added to it. The adjuvant comes from an extract of the soapbark tree,” Esterman mentioned.
Adjuvants stimulate the excused device, giving a more potent and extra long-lasting reaction towards the virus.
Some crowd don’t agree with mRNA vaccines, or have had unholy reactions to them, Esterman mentioned.
“Novavax being a traditional vaccine would therefore be preferred by these people, and might encourage more to get vaccinated.
“Having mentioned that, when the actual bivalent Novavax vaccine used to be licensed in Australia, my working out is that gross sales had been disappointing.”
Consistent with the TGA, best 268,000 doses of the Novavax vaccine were administered in Australia to October 2023.
