Why don’t vaccines carry over genetically?

Just curious with everything going on why vaccines don’t essentially pass down to our children genetically if we’ve been immunised. Is it purely because we didn’t genetically start with that or purely down to the synthetic (well atleast not made naturally by the body) nature of the vaccinations?

1) Vaccines do not alter your genetic information, i.e. those in the form of RNA (the new ones, because up until today they were protein based) do not integrate into the genome.

2) even if RNA vaccines could integrate into the DNA, you still wouldn't pass them on because vaccinations are injected into somatic cells, not into germ cells (inside testicules or oocytes, for instance...nobody would want that tbh). To pass genetic information on you need to alter the DNA of germ cells.
