ok so what we know so far is the virus has 4 parts, the spike, the spike collar, the shell, and the rna which codes to have the body create and assemble the 4 parts. the shell is from the common cold. the spike collar that holds the spike together at the base and attaches it to the shell, is from hiv. The 'spike' that allows the virus to attach to a mammals body cells and gain entry is the 'novel' or new part that was biologically assembled with the other pieces by humans. the 'collar' piece that holds the spike together is part of hiv, which has its own spike unique from the coronavirus spike.

the vaccine has only partial rna, it makes the spike (and the hiv collar hat holds the spike in its shape I believe) but doesn't contain the code to make the shells, reproduce more copies of the rna, and assemble all the parts together.. however your body has code to copy the rna into the dna of cells and then reproduce copies making it a permanent feature, but its a roll of the dice if that happens or not..
