SARS-CoV-2 rS by Novavax
The SARS-CoV-2 rS, developed by US-based vaccine development company Novavax, is undergoing simultaneous Phase 1 and Phase 2 trials in Australia.

The full length recombinant SARS CoV-2 glycoprotein nanoparticle vaccine involves selecting a part of the genetic sequence of the virus that produces antigens (in this case the spike protein). This sequence is then introduced in baculoviruses — pathogens that attack insects.

These modified baculoviruses are then made to infect insect cell culture, so that the cells can produce proteins that are similar in structure to the viral antigens. These proteins are purified and converted into parti
