There is some confusion today among pro‑life people (especially parents) regarding the morality of using vaccines that may have been produced using the tissue of aborted preborn babies.

Aborted Fetal Tissue in Vaccines

Of particular concern are vaccines that were developed in part using fetal tissue derived from aborted babies who died decades ago, and whose tissue is regenerated in laboratories under the names MRC-5 and WI-38. These include Varivax for chicken‑pox, Meruvax II for rubella (German measles), and Havrix and Vaqta for Hepatitis A.1

The MRC-5 and WI-38 cell lines originate from babies aborted in 1961. Their cells were regenerated by Merck and other corporations, and are used in the Varivax and Meruvax II vaccines. These cell lines are technically “immortal,” because technicians can sustain them in a laboratory indefinitely under the proper conditions. This means that the researchers who developed these relatively new vaccines bear no responsibility whatsoever for the original abortions carried out half a world away and half a century ago.2

This is in contrast to some current‑day researchers who experiment on the remains of preborn children. They cooperate so closely with abortion mills in order to receive the tissue they need that they are frequently in the abortuary at the time the abortions are being performed so they can package and preserve the organs immediately.

Our Moral Obligation

In June 2005, the Pontifical Academy for Life published a document entitled Moral Reflections on Vaccines Prepared from Cells Derived from Aborted Human Fetuses, which answers most questions that Catholics might have about the morality of using vaccines that are derived from the cell lines of aborted preborn children.

The document recognizes the great value of eradicating diseases that have plagued mankind for millennia, calling this a “milestone” of modern medical technology. The Catholic Church has always supported advances in all areas of medical technology as long as they adhere to moral standards. However, over the past half-century, many morally questionable ― and outright evil ― practices have surfaced. Certain procedures that attempt to derive good from evil are ethically murky and create doubt, such as producing lifesaving vaccines from a procedure (abortion) that ends life.

The primary question is: How closely do vaccine users cooperate in the evil of abortion?

There are generally three degrees of cooperation regarding the manufacture, sale and use of vaccines originating with aborted babies:

  1. To begin with, those who procure tissue from aborted babies in order to produce a vaccine from it are guilty of formally cooperating in abortion by approving of and taking advantage of the very act of abortion itself. They are as guilty as the boyfriend who pays for the abortion, the friend who drives her to the abortion mill, or the abortionist who performs the actual procedure.
  2. Somewhat removed from this direct cooperation in abortion are those who market, advertise and distribute the resulting vaccines. But these activities are also morally illicit, because they “could contribute in encouraging the performance of other voluntary abortions, with the purpose of producing such vaccines” (Moral Reflections, Section 6).
  3. Finally, there are the doctors and patients who use these vaccines, even though they know about their origin. They are permitted to use the vaccines when no alternative is available, in order to avoid “significant risks to their health” and “indirectly the [health of the] population as a whole.” However, this causes the “moral coercion of the conscience of parents, who are forced to choose to act against their conscience or otherwise to put the health of their children and of the population as a whole at risk. This is an unjust alternative choice, which must be eliminated as soon as possible” (Moral Reflections, Summary).

Why Are Late Abortions Performed?

The document Moral Reflections points out our moral duty to do more than just passively resist evil; we must actively fight it. We are all obliged to “oppose by all means the vaccines which do not yet have morally acceptable alternatives, creating pressure so that alternative vaccines are prepared.”

Father Tadeusz Pacholczyk, Director of Education for the National Catholic Bioethics Center, gives us some guidance on what specific actions we can take. He says that parents can “ask their health-care providers for accurate information detailing whether particular vaccines were developed using cell lines of illicit origin. This engages the health-care profession in a discussion that it very much needs to become party to. Parents can make known their disagreement by writing to the pharmaceutical companies that manufacture the vaccines.”3

The Ethical “Bottom Line”

In summary, conscientious pro‑lifers are forced to weigh their own children’s health against participating in an illicit and immoral procedure that has already killed preborn children. Fortunately, the document Moral Reflections has clarified the situation:

The lawfulness of the use of these vaccines should not be misinterpreted as a declaration of the lawfulness of their production, marketing, and use, but is to be understood as being a passive material cooperation and, in its mildest and remotest sense … [is] morally justified as an extrema ratio [extreme reason] due to the necessity to provide for the good of one’s children and of the people who come in contact with the children [pregnant women].

Dr. Edward J. Furton, a leading Catholic bioethicist, writes:

It seems impossible for an individual to cooperate with an action that is now completed and exists in the past. Clearly, use of a vaccine in the present does not cause the one who is immunized to share in the immoral intention or action of those who carried out the abortion in the past. Neither does such use provide some circumstance essential to the commission of that past act. Thus, use of these vaccines would seem permissible.4

Dr. Furton says that Catholics, by using these vaccines, are not approving of the original abortions in any way. He writes that it would be a “high standard indeed if we were to require all benefits that we receive in the present to be completely free of every immorality of the past.” He also points out that these vaccines certainly will not encourage any more abortions since the cell lines from the original abortions are continuing to grow and duplicate and that therefore “there is little incentive to begin new human cell lines.” In addition, he writes that we may refuse these vaccinations ourselves, but we have a duty to protect the lives and health of our children and must get them vaccinated if no other alternative is available.

RELATED:
Should Aborting Women be Punished?

If Merck or other pharmaceutical corporations were still purchasing large quantities of aborted babies from abortion mills to generate these vaccines, there would be no question as to what the correct course of action would be. But it is certainly licit to use such vaccines when the abortion in question is an act that was accomplished long ago, when no more abortions will be required, and when the lives of many children ― including, perhaps, our own ― will be saved. If the only vaccines available are those derived from aborted preborn children who died many years ago, we may use them because there is no material cooperation in the abortions. If there is any cooperation in the evil of abortion, it rests with the pharmaceutical corporations, not with the people being vaccinated.

    This still does not eliminate the former baby’s DNA present in these vaccines that we pump into our children.
    Foreign DNA causes problems like rejection, for adults who have implant procedures. It is probably not safe for our children either.
    It could be very guilty for the Very very high incidence of Autism is our children today, 55 out of 100 is not acceptable.

    Why can’t these pharmaceuticals return to producing vaccines with former bases that spared our children the neurological damages in their brains from Autism. This is the Best answer to the immorality question!

    I cannot agree that a person receiving a vaccine now does not share the sin of the 60 year old abortion. Evil is timeless. The theory that since the original stem cell lines are prolific into “immortality”. there is low risk of current abortions to provide these cells, I wonder how it would impact the pharmaceutical companies if people would stand on integrity and refuse vaccines made with aborted cells. It might even impact future vaccines,

    Along with aborted fetal cells in vaccines are neurotoxins. If vaccines only had neurotoxins, it would not be a moral choice to give to anyone.

    There are other ways to prevent disease and strengthen one’s immune system.

    So let me get this straight. People “benefitting” NOW from research that is immoral and the crime was committed back THEN, this time difference makes it ok to use the fruits of that labor?

    Why was it that the research from the experiments done on the Jews was destroyed with the explanation that such heinous actions should never be used to benefit others, but somehow the vaccines that came from abortions are ok? Why didn’t we just put the NAZI research in a vault and wait 40-60 years and then start using their discoveries to benefit mankind?

    The duration of time between a heinous action and the average person “benefitting” from that action should play no role in our acceptance of it. It shouldn’t be accepted.

    It can never be morally licit to take a vaccine from an aborted baby cell line. Anyone who claims it is fine is not speaking Catholic truth. Even if they were the Pope. We can never ever benefit from anything that required the death of another human by murder.

    They 100 % use aborted fetal cells from abortions from Planned Parenthood, they also harvest them from live births while the hearts are beating WITH NO ANESTHESIA! Look up Dr Theresa Deischer. Look up Dr. Stanley Plotkin’s deposition. Look up undercover videos at stem cell research centers and Planned Parenthood. They are lying to us all. They end up in your vial and it is frightening. Look up the Hghwire.com Del Bigtree. Vaccines are one of the biggest lies in medicine. They all should be prosecuted for crimes against humanity.
