Obviously, the initial development process of vaccines are still part of the vaccine development process.

Cells from aborted fetuses, which have replicated many times...are still...Cell lines derived from aborted fetuses.

This is true, even when none of the original cells are still present. That's kind of the concept between "cell lines" and "derived from".

Having a problem with a product, which had ever used the benefit of aborted fetuses in its development process, obviously is not the same as thinking it is manufactured with aborted fetus cells, as the oddly included irrelevant end of the quote sets up a drive-by strawman argument...to go along with the rest of the intellectual dishonesty.
