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. don't ask me how i know.
is the Covid "vaccine" purely being used to express 1 gene and "stop" Covid, or has a manufacturer used more of the payload capacity to insert or knock out other genes?
