The use of fetal cells in vaccines is a controversial topic that has raised concerns among some people. It is important to note that vaccines do not contain fetal cells or parts of fetuses. However, certain vaccines, such as those for rubella, chickenpox, shingles, hepatitis A, rabies, and COVID-19, have been developed using fetal cell lines. These cell lines were derived from aborted fetuses in the 1960s and have been continuously cultured and used for vaccine development since then. The reason for using fetal cells is that they have a higher capacity for division and can be stored at very low temperatures, providing an ongoing supply for vaccine manufacturing. Religious and ethical debates surrounding the use of fetal cells in vaccines have led to discussions within religious institutions, such as the Catholic Church, and among various population groups. While some people object to the use of fetal cells on moral grounds, religious leaders and medical professionals have emphasized the safety and effectiveness of vaccines, even those developed using fetal cell lines.

Fetal cells have been used in vaccine manufacturing since the 1930s
The use of fetal cells in vaccine development was partly due to the work of Leonard Hayflick, who joined the Wistar Institute under Dr. Koprowski. Koprowski was a polio researcher who wanted a scientist who could provide cells to his lab and other researchers. Hayflick was adept at the process of culturing cells and sought an aborted fetus from a relatively healthy woman. This allowed him to create a strain for vaccine manufacturing that could be considered a gold standard.
Hayflick's fetal cells were much less likely to have been exposed to viruses, and researchers started using them as growth factories for vaccine viruses. Plotkin, who had been studying rubella, realized that the rubella virus could grow in fetal cells since the disease was most devastating to developing fetuses when their mothers were infected during pregnancy. Koprowski also started working on a version of the polio vaccine grown in fetal cells, performing a series of experiments to determine its safety.
Fetal cells have been used in the manufacturing of several vaccines, including rubella, chickenpox, shingles, hepatitis A, and one version of the rabies vaccine. However, it is important to note that vaccines do not contain fetal cells. The purification processes during vaccine production filter out any fetal tissue, and the same cell lines can be continuously used, so no new aborted fetuses are ever needed.

Religious leaders have evaluated the use of fetal cells in vaccines and deemed it morally acceptable
The use of fetal cells in vaccines has been a topic of ethical debate, with some people expressing concerns about the moral implications of using cells derived from aborted fetuses. However, religious leaders have evaluated the issue and provided guidance that clarifies their stance on the moral acceptability of such vaccines.
The Catholic Church, for example, has acknowledged the sensitivity of the matter and encouraged its members to prioritize alternative vaccines that are produced without human cell lines when possible. At the same time, the Vatican has emphasized that all clinically safe and effective vaccines can be used in good conscience. This stance recognizes the potential life-saving impact of vaccines and draws a distinction between utilizing such vaccines and endorsing the act of abortion.
In the case of COVID-19 vaccines, the Vatican's doctrinal office, the Congregation for the Doctrine of Faith, has stated that it is "morally licit" for Catholics to receive vaccines derived from fetal cell lines or where such lines were employed in testing or development. This position considers the grave danger posed by the pandemic and the duty to protect one's health and pursue the common good.
Similarly, while some Orthodox Christians have expressed concerns about the use of aborted fetal cells in vaccines, a segment of Orthodox priests and bishops has deemed these vaccines morally acceptable. They cite the age of the fetal cell lines, which date back to the 1960s, and the principle of the greater good, where the lives saved by the vaccines outweigh the ethical concerns.
It is worth noting that the use of fetal cells in vaccine development has a long history, with the first medical applications occurring in the 1930s. Fetal cells were chosen due to their reduced likelihood of viral exposure, which was crucial for creating safe and effective vaccines. Today, fetal cell lines continue to be used in the production of vaccines against diseases such as rubella, chickenpox, shingles, hepatitis A, and rabies.

Fetal cells are used because they are less likely to be exposed to viruses
Fetal cells have been used in the development of vaccines since the 1930s. The use of fetal cells in vaccine development is a controversial topic, with some people expressing concerns about the morality and safety of using such cells. However, it's important to note that vaccines do not contain fetal cells. Instead, they are used as growth factories for vaccine viruses, and rigorous purification processes ensure that no fetal tissue remains in the final product.
The history of fetal cell use in vaccine development can be traced back to the work of researchers Hayflick, Koprowski, and Plotkin. They recognized the potential risk of contamination by unknown viruses when vaccines were grown in animal cells. Hayflick, in particular, had access to fetal cells and proposed their use in vaccine development because they were less likely to have been exposed to viruses. This was a significant concern, especially after it was discovered that the monkey kidney cells used in the early polio vaccines contained a cancer-causing virus called SV40.
Hayflick's fetal cells were obtained from aborted fetuses, which, at the time, was considered illegal according to federal and state laws. However, abortions deemed medically necessary were referred to as "therapeutic abortions" and were allowed in limited situations. Hayflick sought aborted fetuses from relatively healthy women to ensure that the cells were free of viruses and cancer, and he successfully isolated and cultured these cells for vaccine development.
The use of fetal cells in vaccine development has been particularly important for specific vaccines, such as the rubella vaccine. Rubella, also known as German measles, can cause severe disabilities in developing fetuses when their mothers are infected during pregnancy. By growing the rubella virus in fetal cells, researchers were able to create an effective vaccine. Additionally, fetal cells have been used in the development of vaccines for chickenpox, shingles, hepatitis A, and a version of the rabies vaccine.
While the use of fetal cells in vaccine development has raised ethical concerns, religious authorities like the Vatican have clarified that it is "morally licit" to use vaccines derived from fetal cell lines, especially during public health crises like the COVID-19 pandemic. This stance considers the duty to protect one's health and pursue the common good. It is important to address misinformation and provide accurate information to the public, ensuring that people can make informed decisions about their health and the health of their children.

Vaccines do not contain fetal cells or tissue
It is understandable that people have concerns about what goes into vaccines. Vaccines are rigorously tested before being licensed, and misinformation about their ingredients can cause unnecessary worry.
Some vaccines are made using cells grown in the lab from fetal tissue donated in the 1960s and 1980s. These fetal cell lines are descendants of the original fetal tissue, not the tissue itself. No new fetal tissue or abortions are required to maintain these cell lines. The final vaccine is a purified product that contains no fetal cells or tissue.
The Vatican has also clarified that "all vaccinations recognized as clinically safe and effective can be used in good conscience, with the certain knowledge that the use of such vaccines does not constitute formal cooperation with the abortion". This means that, from an ethical perspective, it is acceptable to receive vaccines even if their history is connected to abortion. The common good may recommend vaccination, especially to protect the most vulnerable.
It is important to remember that vaccines have been proven to save lives. A child who is not vaccinated is at risk of catching a dangerous or deadly disease. Some of the worst diseases, like polio, measles and Hib meningitis, have been greatly reduced or eliminated thanks to vaccines.

Fetal cells are used to grow viruses in controlled conditions
Fetal cells have been used in the manufacture of vaccines since the 1930s. They are used to grow viruses in controlled conditions. The use of fetal tissue in vaccine development involves growing viruses in cultured (laboratory-grown) cells that were originally derived from human fetal tissue. This practice has been met with opposition on religious and moral grounds.
The reasons that fetal cells were originally chosen for this purpose include the fact that viruses tend to grow better in human cells than in animal cells. Fetal cells, in particular, were chosen because they were isolated from the sterile environment of the womb, meaning they were not infected with other viruses. Additionally, because fetal cells have not divided as many times as other cell types, they can be used for longer.
The first medical application of cell lines derived from fetal tissues was in the production of the first polio vaccines. Scientists at the Karolinska Institute in Sweden propagated a polio virus in fetal cell lines to make a polio vaccine in the 1950s. Fetal cells have also been used to develop vaccines for rubella, chickenpox, shingles, hepatitis A, and one version of rabies vaccine.
The COVID-19 vaccine (J&J/Janssen) is made using fetal retinal cells. The retinal cells used to make this vaccine were isolated from a terminated fetus in 1985 and adapted for use in growing adenovirus-based vaccines in the late 1990s. Several other COVID-19 vaccines in use or development also use the cell lines HEK-293 or PER.C6 for production.
It is important to note that vaccines do not contain fetal cells or pieces of DNA that are recognizable as human DNA. Once the vaccine viruses are grown in the cells, the next step is to purify the vaccine viruses away from the cells and substances used to help the cells grow.

Frequently asked questions
The Johnson & Johnson vaccine used foetal cell cultures, specifically PER.C6, a retinal cell line that was isolated from a terminated foetus in 1985, in order to produce and manufacture the vaccine. Pfizer and Moderna have also used the same cell line for testing. However, it's important to distinguish between "fetal tissue cells" and "cells derived from a long chain that arose from cells in fetal tissue."
This is a complex ethical question. Most Christian ethicists agree that foetal tissue donation is not inherently unethical if the tissue was obtained from a spontaneous abortion (miscarriage) or an ectopic pregnancy and was willingly donated by the parent. However, the donation of foetal tissue may be morally questionable when the tissue is derived from a foetus that has been aborted.
It is unlikely that the COVID-19 vaccines have any effect on fertility or harmful effects on pregnant people or foetuses. However, pregnant individuals considering COVID-19 vaccination may benefit from discussing the benefits and potential risks with their healthcare provider.
