Ivy/Burble
Thanks for your explanations of the research I posted last night. Just to add a couple of points, if they're not quite right then perhaps you could correct them Burble?
As I understand it and in very simple terms, COVID-19 uses receptors on the Spike (S) protein to enter cells whilst the Nucleocapsid Protein helps it spread and thrive once it has infected a cell.
If you want to build a preventative vaccine, it therefore makes sense to target the Spike protein by generating neutralizing antibodies to prevent the virus entering cells in the first place. That's why all developers are targeting various regions of the Spike. However, one or two, including Scancell are building vaccines that will also generate T cell responses against the N protein which should give a belt and braces approach.
The other major benefit of targeting the N protein is the fact that it remains relatively unchanged between different coronaviruses. So as the virus mutates and as new ones come along, Scancell's vaccine may well still offer protection. This will be really important on an ongoing basis as you don't want to be having to constantly develop new vaccines as and when the virus mutates.
