You have the cell
The cell is cloned.
The DNA of the cloned cell is replicated.
The opposite DNA sequence is created
This sequence is then used.

All this happens before the new sequence is used to create another sequence with the desired characteristics for use to then replicate.

This happens over and over.

This can be done with any stem cell.

Again, I am not weighing in on objections to vaccines, not valid moral objections to them but I will object to badly thought out medico-moral theology

You can't have it both ways you agree with Fr Scott until 2006 then he's wrong ok logical.

So the cell is from abortion or a cadaver?

Was the abortion done to derive the cell?

Traditional bioethicists do not exist because there's no one qualified to teach. What you are suggesting is that we listen to people not properly trained?
Personally I would prefer a surgeon to operate but you prefer an anesthesiologist.

WI38 and MRC5 are from directly procured abortions for the purpose of making cell lines. This is one major difference but you prefer to lump all reasoning together.

You may be shocked that pre Vatican II it was lawful for a nurse to assist at an abortion for certain grave reasons so long as what she was doing could have been done by another ( handing over instruments, patient observation, etc)?  

We are not protestant, we don't make up science or moral theology. We follow reasoned teaching presented by theological experts in their field. Especially when we can not make a proper judgement on a subject outside our competency. We don't prescribe our own penances, hear our own confessions, or baptize ourselves either

I already quoted studies on the HEK.

You're still not addressing my points,

You still don't get the difference between WI and HEK neither do your sources. You're taking a view as if no differences can be had between two different things.

Hmm.  I think I might be seeing what you're getting at here.  Would this situation be analogous to the transplant of a heart that came as a result of a murder?  In that case the recipient would not have cooperated with the evil...murder ....simply because they got that person's heart.
