Where in the fuck is the THC gland located?
Phonefagging. Sorry.
Because Jesus said, “don’t do that”?
Nothing changes at the genomic level.
A vaccine will make a big sticky molecule (antibody). That sticky molecule may bind to things and get in the way. Sometimes antibody binding to thins on the cell surface can lead to the death of the bound cell.
By what mechanism does any vaccine mutate a human stem cell?
My poop contains human DNA also. I doubt it is mutagenic, or a tumor promoter.
