Yeah, putting it in your nose definitely has far fewer risks than putting it in your blood, and that greatly reduces my skepticism. But the set of peptide sequences you naturally encounter is a tiny subspace of the total space of possible proteins, and so I’m less convinced that you might not have side effects.
Also, having random peptides along with an adjuvant (which triggers an immune response) might be risky even in cases where those random peptides are otherwise completely safe.
