Moonparty,
Re. your 16.47/16.47 - there are only a few vaccines in development targeting both the S & N proteins and very, very few I could find that are actually in clinical trials. In terms of how their approach compares to Scancell:-
Two of the most advanced in development (ImmunityBio and Vaxart) use adenovirus vectors - similar to AstraZeneca but a human rather than chimpanzee form. On the plus side this is tried and tested technology but drawbacks are that adenovirus-vectored vaccines aren't so easy to manufacture and could trigger an immune reaction to the vector itself resulting in reduced efficacy. There are some known serious (but very, very rare) side effects.
Gritstone are using a self-amplifying mRNA vaccine targeting both the S & N proteins - once injected, the mRNA is self-replicating so should require lower doses than the existing Pfizer/Moderna mRNA vaccines. I believe Gritstone are using lipid nanoparticles to deliver their vax and assume that like the other mRNA vaccines, this will require cold storage and has the same stability issues.
Finally, like Scancell, Genexine are developing a DNA vaccine but theirs is delivered via electroproation.
So a few different approaches and it'll be interesting to see how they all play out. So far the concept of targeting both proteins looks very promising and it will be great news for Scancell if/when any of these trials produce positive results.
