As for monoclonal antibody therapy, it is ethically questionable in the first place because it uses fetal tissue cells (from abortion) and in 2019 the US authorities suspended funding for such research - but that does not mean that it is not funded by private money. Trump received that therapy as they say from "compassionate use".
the human cell lines used as incubators for the MA's are not from any abortions occuring 1980-2021
doctors are not ripping fetuses out of women today to then use for other things without consent
what happened was a woman decided to have a abortion in the 1970's.
for her own personal reasons
and for the heck of it gave permission for the tissues removed to be used for science.
those cells are then replicated. and its the replicate that is then used for science
there is no fetus used. its cells from like 6 replications away from what was fetal tissue
the fetus died in the 1970's and is not sitting in some lab somewhere
in short
its like if someone 50 years ago was going to die and the family signed permission slip that when they die. they want the body donated to science
in the 1970's the body has a biopsy and they take some tissue out of it.
its not THAT tissue thats used in 2020.
the body is then buried/cremated. and the body is no longer in a lab
as for the biopsy tissue extracted..
THAT tissue is replicated. and new tissue is created call it T1
T1 tissue is replicated. and new tissue is created call it T2 created in the 1980's
T2 tissue is replicated. and new tissue is created call it T3 created in the 1990's
T3 tissue is replicated. and new tissue is created call it T4 created in the 2000's
T4 tissue is replicated. and new tissue is created call it T5 created in the 2010's
T5 tissue is replicated. and new tissue is created call it T6 created in the 20XXs
its T6 tissue that is used. (its actually more like T2500 by now but you get the idea)
in short your corpse in 2021 is not being experimented on when you had a biopsy in 1970's. the tissue extracted from you in the 1970's is not the tissue being experimented on
your body is long gone and buried/cremated 50 years ago
