the Covid "vaccine" gene therapy process uses the shell of a viral particle (HIV) that writes directly to a cell's DNA. the particle is coded to attach to a specific enzyme or protein (hopefully identifying your T cells).
at the time of vaccine production, each carrier particle has a payload capacity of 3 genes, which can be used to knock out up to 5 SIRNA (15 genes), or insert up to 3 new genes, in the host cell's DNA.
we don't yet know the exact contents of the payload…..
the purpose of the viral particle's payload instructions (the mRNA) is to modify the host cell's dna. the payload will insert a new gene or genes, or shut down a gene or genes. these changes to the host cell's dna trigger the cell's new (designed) behavior. a viral particle's custom payload can add up to 3 genes, or shut down up to 15 genes. i know this from my work in the context of gene therapy (currently in phase 1 trial for an AIDS cure)
the big question i have is the exact nature of these custom payloads in the Covid vaccines.
