1 Corinthians 8 comes to mind.
HEK293 are not fetal cells. They aren’t even human anymore in that they were transformed via viral transduction, then selected for over time for cells that survived and that grew well and were easy to maintain. These selected cells no longer have the human complement of 46 chromosomes.
The initial source of cells used to be modified and selected to create this stable cell line was a girl who was aborted in Europe in 1973. The reason for the abortion or whether it was spontaneous or induced is not known.
The cells are not in the vaccine or used to make the vaccine but we’re used To separately grow proteins that are used in a test to see if the vaccine was functioning right.
Respectfully, the fact that these cells can be traced back to the human being that was aborted in the 1970's makes them human in my view.
