"While the ultrasound procedure presents minimal risk to the fetus, diagnosis of microcephaly by ultrasound has the potential to place the fetus at greatest risk due to the mother’s decision to abort the fetus. To minimize the possibility that involvement in research will influence a mother’s decision to terminate a pregnancy, 45 CFR 46, Subpart B, indicates that, “no inducements, monetary or otherwise, will be offered to terminate a pregnancy” (U.S. Department of Health and Human Services 2009). In addition, it “excludes researchers from any decisions as to the timing, methods, or procedures used to terminate a pregnancy, or determinations on the viability of the fetus at the termination of the pregnancy” (U.S. Department of Health and Human Services 2009). Nevertheless, it is very challenging to design experimentation that identifies microcephaly in utero, which would not increase the number of elective abortions regardless of whether research scientists desiring aborted fetal tissue were excluded from involvement with patients’ decision making. Here, the Catholic Church’s perspective is invaluable: “sick and disabled people are not some separate category of humanity; in fact, sickness and disability are part of the human condition and affect every individual, even when there is no direct experience of it” (Congregation for the Doctrine of the Faith 2008, no. 22). Therefore, only an experimental design that recognized the dignity and legal status of both healthy and diseased fetuses would effectively discourage elective abortion in research studies. This design would not only protect the unborn but also limit scandal (Catechism of the Catholic Church, no. 2284), a behavior that leads another to do evil, from the actions of mothers and scientists. Development of a vaccine against Zika virus is a top priority; and as the virus infects fetal brain tissue, it is likely that cultivation of Zika virus for use in vaccines could occur in fetal tissue derived from elective abortions. However, alternative tissue that is not derived from elective abortions could be equally effective and should be investigated."
