"LM is probly nothing more than a vector, a delivery vehicle."
Sounds like more than that to me. "Lm Technology represents an advancement in the field of immunotherapy, as its comprehensive immune stimulation and priming redirects a “pathogen-like” response against cancers. The LM Technology vector, the basis of each of our products, is designed to stimulate multiple immunotherapy mechanisms."
It absolutely is nothing more than a vector, but if it happens to be a better vector than others, it will make a big difference. Otherwise, there's not much to distinguish it from other neoantigen-based immunotherapies.
