Incorrect; according to Wikipedia, Corbevax just includes the receptor binding domain of the spike protein. It doesn't include other parts of the virus - were you confused by the adjuvants?
Anyway, you might be interested in Novavax if you're looking for a nice, classic covid vaccine. It's not any more effective than the mRNA vaccines, but it's FDA-approved.
Novavax UK results on par with mRNA vaccine while trials conducted with variants alpha/beta already circulating. due to unbinding or cross over we cannot really measure long term protection. but several studies show 2373 is better but nobody knows it
