effects of injecting human cells

[Drolefille]

*pulls up chair and corn yet again*

Vaccines are meant to be attacked by your body. You give your body dead (or weak) disease cells and your body's immune system attacks the cells thus creating a strong immune response that will prevent you from getting X disease because your body already has T-cells to fight it, or perhaps more accurately it will be able to recreate the T-cells. I don't know that there's really a threat then from human cells being included in this vaccine except that you would not be able to accept a transplant from said human (which is moot since said "human" is not exactly walking around) because your body is primed to attack it. Maybe.

I'm not even sure that would be a problem.
