My prediction is they will delay introducing it to allow for full takeup of Pfizer, its meant to be delayed now and not here until 2022 ...

Novavax uses synthetic component, made in the lab to mimic a part of the virus, introduced by a neutral vector. AZ and J&J use a segment of virus DNA introduced using a neutral vector.
I heard it summarised, Pfizer/Moderna are completely new synthetic, Novavax is 50/50 new synthetic / natural traditional, and AZ and J&J are 100% natural traditional. That is natural as in as natural as they can be, and synthetic as in novel.
The age of the technologies used is the give away, AZ, Novavax and J&J uses techniques in manufacture around since the 60s. The mRNA vaccines made by Pfizer and Moderna did not exist until about the mid 2000s.
