Advocate for Morally Acceptable Vaccine Development

The Holy Father, through the CDF, and our Bishops (along with others) have been clear that while we are able to accept the currently-available COVID-19 vaccines in good conscience, we are also obligated to both avoid scandal and advocate for the development of vaccines that are developed in morally acceptable ways. The advocacy can take many forms, including…

  • Donating to organizations that are developing such vaccines, including the JP2 Medical Research Institute
  • Thanking companies that are developing morally acceptable vaccines including Sanofi Pasture (Human Life Action provides a convenient contact template for Sanofi specifically)
  • Urging companies to are almost there to switch to a fully morally acceptable vaccine development process. You can contact Pfizer here and Moderna here.
  • Charitably admonishing companies that are not almost there (i.e., developing very morally problematic vaccines) to change course. AstraZeneca is the company closest to getting a severely morally problematic vaccine approved and can be contacted here.

FLG COVID-19 Vaccine Statement

Updated 12/21/2020 @ 1120

Just today the Congregation for the Doctrine of the Faith has published a document entitled “Note on the morality of using some anti-COVID-19 vaccines.” This provides important clarification on the stance of the Catholic Church. We, without question, accept the CDF’s guidance and if there is anything in our statement below that appears to be in contradiction with the CDF’s document, it is our error.

COVID-19 Vaccines Associated with Abortion: A Moral Dilemma

The Church’s position that abortion is a grave moral evil has been consistent since the 1st century and is definitive.[1] Since some COVID-19 vaccines use abortion-derived fetal cell lines in one or more aspects of their production, their use requires careful ethical reflection.[2]  On the one hand, such vaccines can do much good in protecting the health of persons and populations, while on the other hand, they are linked to an act that intentionally and unjustly ended the life of a human being.  Herein lies the moral dilemma.

COVID-19 Vaccines: There are Ethical Differences Among Them!

It is important that Catholics understand that of the numerous COVID-19 vaccines currently in development world-wide, there is great variation in their degree of use of abortion-derived fetal cell lines, varying from zero use to extensive use. The National Catholic Bioethics Center (NCBC) identifies three categories of COVID-19 vaccines, ranging from a Category 1 Vaccine which uses no morally problematic cell lines and thus poses no ethical problem, to a Category 3 Vaccine, which uses the cell lines in one or more aspects of production, including the manufacturing process which is the most ethically problematic. Category 2 vaccines use the cell lines in an incidental part of the development process such as laboratory testing and so are minimally problematic.  Table 1 describes these categories in more detail.

In December 2020, two COVID-19 vaccine candidates – Pfizer-BioNTech and Moderna – received emergency use authorization from the FDA through Operation Warp Speed protocols.   Information provided by the Charlotte Lozier Institute classified both vaccines as Category 2 (minimally problematic). The six other Operation Warp Speed vaccine candidates either meet Category 3 (considerably problematic) criteria, or don’t have enough public information to be categorized.  It should be noted that these and other COVID-19 vaccine candidates may be approved and become available to the public in the future.  For this reason:

   When there is a choice amongst COVID-19 vaccines, Catholics should specifically ask for, and seek out, the least morally problematic vaccine.

Deciding: Help from the Magisterium

The Magisterium of the Catholic Church offers guidance to Catholics who are pondering whether to receive morally problematic vaccines.  In essence, while the Church firmly views a person’s right to exercise his personal freedom as a requirement of ensuring human dignity, it is moderated by a responsibility to use that freedom to promote the common good and moral order.[3] The following Church statements provide valuable considerations in this matter:

* The 2008 document Dignitas Personae (Section 35) allows for the use of morally problematic vaccines for grave reasons such as danger to one’s health, clarifying that “…grave reasons may be morally proportionate to justify the use of such ‘biological material.’”

* A 2005 letter from the Pontifical Academy of Life  supported the right to abstain from receiving morally problematic vaccines, but did not support an unconditional right to do so when the disease posed a serious threat and the vaccine was sufficiently effective.

* In a 2015 statement, Conscience Exemption for Vaccines based on Fetal Tissue from Abortions, the U.S. Catholic Conference of Bishops (USCCB) noted that a Catholic parent could seek an exemption for their children from morally problematic vaccinations when a conscience exemption was available and when doing so would not pose a serious risk to the population.

* Most recently, the USCCB reminded Catholics that they are ethically permitted to receive a COVID-19 vaccine, even if it is morally problematic, given the urgency of the pandemic, the lack of available vaccines, and the remote connection to the original abortion. They described the decision to vaccinate as an act of charity and love towards one’s neighbor and perhaps the most important feature of receiving such a vaccine.

While these Church statements do not obligate Catholics to receive a COVID-19 vaccine, they clearly favor doing so.  However, out of respect for personal freedom and a person’s conscience formed by well-considered reasons, an individual’s decision to forego a COVID-19 vaccine should be respected.

The Church has conditionally stated that it is permissible, and even advisable                                            to receive morally problematic vaccines when there are no alternatives and when there is substantial risk to one’s own health or to the health of others.

However, the Church deems that the use of such vaccines is not obligatory, out of respect for personal freedom and a person’s conscience formed by well-considered reasons.

Importance of Advocacy

The Church asks more of Catholics in this matter.  It calls Catholics to actively advocate for the development of ethical vaccines, free from any association with abortion or other immoral acts.   Catholics can bring pressure to bear on pharmaceutical companies, researchers, and governments to eliminate the use of unethical cell lines.  Researchers at Catholic universities have an unique opportunity to take the lead in this endeavor, so that one need never choose between their conscience and health.  

Catholics should actively advocate against the use of abortion-derived fetal cell lines in vaccine research, manufacturing, and testing, and encourage the use of ethical alternatives.

COVID-19 Vaccines

The Guild has been closely following the development, and now distribution, of vaccines for COVID-19. There has been much written on this topic and we are in particular very thankful to the USCCB for their recent guidance on this important topic.

We will be posting our detailed thoughts on all of this shortly. In the meantime, we would like to provide some resources that we hope will be helpful in thinking through this important issue.
