Using Vaccines Obtained From Intentionally Aborted Human Embryos
Further Clarification Needed for Parents, Researchers
WASHINGTON, D.C., JAN. 12, 2011 (Zenit.org).- Here is a question on bioethics asked by a ZENIT reader and answered by the fellows of the Culture of Life Foundation.
Q: I would love to see some more discussion or advice on the use of vaccines. [...] If my memory served me correctly, in the United States, all of the vaccines for Chicken Pox and the standard MMR [measles, mumps, rubella] protocols are developed from aborted children. Considering the ubiquity of these particular vaccines, I believe it is an issue that needs further exploration, discussion, and guidance from the Church and her thinkers. -- C.G., Charleston, South Carolina, USA
William E. May offers the following response:
A: The reader's question is specifically the one used in the heading of this article. However, that issue was addressed earlier in response to another reader's question (ZENIT, DEC. 15, 2010). It therefore seems proper here to raise the following question: "Is it ever morally licit to use biological material of illicit origin?"
I offer below a review of relevant Church teaching regarding this question and other helpful sources.
Relevant Church Teaching
The Congregation for the Doctrine of the Faith's 2009 document "Dignitas Personae" (The Dignity of the Person) addresses the question regarding the use of "biological material" of illicit origin in numbers 34 and 35, and in doing to refers to relevant teaching of Pope John Paul II in his encyclical "Evangelium Vitae" (The Gospel of Life) and to the congregation's 1987 document "Donum Vitae" (Instruction on Respect for Human Life in Its Origin and the Dignity of Procreation).
Number 34 of "Dignitas Personae" says the problems are cooperation in evil and giving scandal. Number 35 says that a different situation exists when researchers use "biological material" of illicit origin produced apart from their research or commercially obtained and refers to John Paul II's "Evangelum Vitae." It declares that "Donum Vitae" (Part I, No. 4) articulated the principle to be followed: "The corpses of human embryos and fetuses [...], deliberately aborted or not, must be respected just as the remains of other human beings. In particular, they cannot be subjected to mutilation or to autopsies if their death has not yet been verified and without the consent of the parents or of the mother. Furthermore, the moral requirements must be safeguarded that there be no complicity in deliberate abortion and that the risk of scandal be avoided."
Number 35 of "Dignitas Personae" considers "the criterion of independence." According to it, the use of "biological material" of illicit origin would be ethically permissible if there is a clear separation between those who produce, freeze, and cause the death of human embryos, and the researchers involved in scientific experimentation. "Dignitas Personae" expresses caution here, saying that of itself this criterion might not be sufficient.
It declares: "There is a duty to refuse to use such 'biological material' even when there is no close connection between the researcher and the actions of those who performed the artificial fertilization or the abortion, or when there was no prior agreement with the centers in which the artificial fertilization took place. This duty springs from the necessity to remove oneself, within the area of one's own research, from a gravely unjust legal situation and to affirm with clarity the value of human life. Therefore, the above-mentioned criterion of independence is necessary, but may be ethically insufficient."
But it goes on to note that "within this general picture there exist differing degrees of responsibility. Grave reasons may be morally proportionate to justify the use of such 'biological material.' Thus, for example, danger to the health of children could permit parents to use a vaccine which was developed using cell lines of illicit origin, while keeping in mind that everyone has the duty to make known their disagreement and to ask that their health care system make other types of vaccines available. Moreover, in organizations where cell lines of illicit origin are being utilized, the responsibility of those who make the decision to use them is not the same as that of those who have no voice in such a decision."
"Dignitas Personae" seems here to follow the position taken by Elio Sgreccia regarding use of a measles vaccine developed by making use of aborted fetuses; for a summary of Sgreccia's position, see "On Vaccines Made from Cells of Aborted Fetuses: Pontifical Academy for Life Response," (ZENIT, JULY 25, 2005).
Comment
Christian Brugger offers important observations on the treatment in "Dignitas Personae" of this issue (see E. Christian Brugger, "Strengths and Weaknesses of 'Dignitas Personae,'" in "Symposium on 'Dignitas Personae,'" National Catholic Bioethics Quarterly. Vol. 9.3. Autumn, 2009, 487-481). Commenting on the passage in number 35 about the duty to refuse to use such "biological material" even when there is no close connection between the researcher and the actions of those who performed the artificial fertilization or the abortion, he wonders whether this "would this apply to an epidemiologist in 2009 doing research on … cell lines … or vaccines derived from those lines, given that both were taken from electively aborted fetuses? The moral wrong -- the grave evil of abortion -- was done nearly forty-five years ago. [...]
"Is a researcher's duty to refuse to work on those materials exceptionless, even when the refusal could result in harms to the researcher and to his or her family? The text [of "Dignitas Personae"] indicates that it is not [exceptionless]. It states that grave reasons may be morally proportionate to justify the use of such 'biological material.' But the Instruction ["Dignitas Personae"], following the 2005 Pontifical Academy for Life text, "Moral Reflections on Vaccines Prepared from Cells Derived from Aborted Human Fetuses," only mentions parents consenting for grave reasons to their children's immunization. Where does this leave morally conscientious researchers?"
This is a subject that needs further clarification by the Church.

May Researchers Use "Biological Material" Unjustly Obtained?
Considerations of "Grave Reasons" and Exceptions
By William E. May
WASHINGTON, D.C., DEC. 15, 2010 (Zenit.org).- If an unborn baby in the fetal or embryonic stage of life dies as a result of a miscarriage it would not be immoral to do worthwhile scientific research using tissues taken from it.
But, as Germain Grisez noted in his massive book on "Difficult Moral Questions," a serious problem of conscience can frequently face pro-life scientists and researchers regarding use of tissues taken from embryonic or fetal human persons who were intentionally aborted.
The quandary is the following: Suppose that it is not possible to do the research proposed by using spontaneously aborted unborn babies who miscarry. For example, certain research may require using embryonic/fetal tissue that must be fresh and not frozen or in any way not normal and tissues from miscarried embryos/fetuses do not meet these criteria. What should a conscientious pro-life person do if his research center agreed to use biological material obtained as a result of the intentional abortion of babies in their embryonic or fetal stages of life?
Grisez concluded that the scientist ought not participate in the research nor cooperate with it in any way, even by advising a colleague who would take his place but who is not as knowledgeable about the science involved as he is. Grisez, however, thinks that if certain conditions are fulfilled, he could offer this colleague some advice if it justified tolerating bad side effects that would accompany the discovery of a procedure that would also greatly benefit unborn babies (pp. 385-388).
Grisez's book was published before the 2009 Congregation for the Doctrine of the Faith's document "Dignitas Personae," in which the question of using "biological materials" obtained illegally is addressed. I will summarize the teaching of "Dignitas Personae" and then offer comments on it.
Biological materials illegally procured
Part III of "Dignitas Personae" is called "New treatments which involve the manipulation of the embryo or human genetic patrimony." No. 34 first identifies a common situation causing moral problems: "For scientific research and for the production of vaccines or other products, cell lines are at times used which are the result of an illicit intervention against the life or physical integrity of a human being. The connection to the unjust act may be either mediate or immediate, since it is generally a question of cells which reproduce easily and abundantly. This 'material' is sometimes made available commercially or distributed freely to research centers by governmental agencies having this function under the law. All of this gives rise to various ethical problems with regard to cooperation in evil and with regard to scandal. It is fitting therefore to formulate general principles on the basis of which people of good conscience can evaluate and resolve situations in which they may possibly be involved on account of their professional activity (emphasis in original)" ("Dignitas Personae," No. 35).
No. 35 points out a somewhat different situation -- the precise one of concern to us -- with its set of moral issues, stating: "A different situation is created when researchers use 'biological material' of illicit origin which has been produced apart from their research center or which has been obtained commercially. The Instruction 'Donum Vitae' formulated the general principle which must be observed in these cases: 'The corpses of human embryos and fetuses, whether they have been deliberately aborted or not, must be respected just as the remains of other human beings. In particular, they cannot be subjected to mutilation or to autopsies if their death has not yet been verified and without the consent of the parents or of the mother. Furthermore, the moral requirements must be safeguarded that there be no complicity in deliberate abortion and that the risk of scandal be avoided'" ("Donum Vitae," I, 4).
In a centrally important passage, No. 35 then considers the "criterion of independence" proposed by some. According to this passage, the use of such "biological material" would be ethically permissible provided there is a clear separation between those who produce, freeze, and cause the death of embryos and researchers involved in scientific experimentation.
"Dignitas Personae" expresses caution here, arguing that of itself this criterion might not be sufficient "to avoid a contradiction in the attitude of the person who says that he does not approve of the injustice perpetrated by others, but at the same time accepts for his own work the 'biological material' which the others have obtained by means of that injustice.
"When the illicit action is endorsed by the laws which regulate health care and scientific research, it is necessary to distance oneself from the evil aspects of that system in order not to give the impression of a certain toleration or tacit acceptance of actions which are gravely unjust. Any appearance of acceptance would in fact contribute to the growing indifference to, if not the approval of, such actions in certain medical and political circles."
In fact, "there is a duty to refuse to use such 'biological material' even when there is no close connection between the researcher and the actions of those who performed the artificial fertilization or the abortion, or when there was no prior agreement with the centers in which the artificial fertilization took place. This duty springs from the necessity to remove oneself, within the area of one's own research, from a gravely unjust legal situation and to affirm with clarity the value of human life. Therefore, the above-mentioned criterion of independence is necessary, but may be ethically insufficient."
Nonetheless, "Dignitas Personae" goes on to declare: "Within this general picture there exist differing degrees of responsibility. Grave reasons may be morally proportionate to justify the use of such 'biological material.' Thus, for example, danger to the health of children could permit parents (emphasis added) to use a vaccine which was developed using cell lines of illicit origin, while keeping in mind that everyone has the duty to make known their disagreement and to ask that their healthcare system make other types of vaccines available. Moreover, in organizations where cell lines of illicit origin are being utilized, the responsibility of those who make the decision to use them is not the same as that of those who have no voice in such a decision" (No. 35).
Comment
Christian Brugger offers important observations on the treatment of this issue in "Dignitas Personae."[1] Commenting on the passage in No. 35 about the duty to refuse to use such "biological material," even when there is no close connection between the researcher and the actions of those who performed the artificial fertilization or the abortion, he wonders whether this would apply to an epidemiologist in 2009 doing research on the WI-38 or MRC-5 cell lines, or to vaccines derived from those lines, given that both were taken from electively aborted fetuses?[2]
The moral wrong -- the grave evil of abortion -- was done nearly 45 years ago. Is a researcher's duty to refuse to work on those materials exceptionless, even when the refusal could result in harms to the researcher and to his or her family? The text of "Dignitas Personae" indicates that it is not exceptionless. It states that "grave reasons may be morally proportionate to justify the use of such 'biological material'" (No. 35). But the Instruction "Dignitas Personae," following the 2005 Pontifical Academy for Life text, "Moral Reflections on Vaccines Prepared from Cells Derived from Aborted Human Fetuses," only mentions parents consenting for grave reasons to their children's immunization. Where does this leave morally conscientious researchers?"
I think that if the research is the kind that reasonably promises to provide a great benefit to unborn human subjects who are vulnerable to specific kinds of pathologies from which the research will protect them, as was the case of the research involved in the WI-38 and MRC-5 experiments that Brugger summarizes, then the kind of exception allowed for by "Dignitas Personae," No 35, is present. In all likelihood this kind of exception may simply not have occurred to the Congregation for the Doctrine of the Faith in preparing the 1987 Instruction "Donum Vitae." It seems to me analogous to the situation discussed by Grisez when he thought the solid pro-life researcher could advise a colleague less knowledgeable than he about using unjustly obtained embryonic/fetal tissues in research that reasonably promised great benefit to the unborn, tolerating the evils involved.
