Fetal cells have been used in the development of vaccines since the 1930s. They are used to grow viruses in a laboratory setting, as viruses tend to grow better in human cells than animal cells. The use of fetal tissue in vaccine development is a contentious issue, particularly for those with religious convictions, as the cell strains in use originate from abortions. However, the resulting vaccines do not contain fetal tissue or cells, and the original fetal cells were obtained decades ago, so no further sources of fetal cells are needed.

Fetal cells are used to grow vaccine viruses
Fetal cells have been used to develop vaccines since the 1930s. One of the first applications of fetal cell lines was in the production of the polio vaccine in the 1950s. Scientists at the Karolinska Institute in Sweden used fetal cell lines to make a polio vaccine that was given to about 2,000 children.
Fetal cell lines are derived from stem cells originally taken from aborted fetuses. These cell lines are important research tools as they offer a stable medium for experiments. Fetal cells are also used because they are isolated from the sterile environment of the womb, meaning they are not infected with other viruses. This ensures that the vaccine produced in these cells does not inadvertently introduce any other viruses.
Viruses need cells to grow and tend to grow better in human cells than animal cells because they infect humans. Fetal cells are also preferable because they have not divided as many times as other cell types, so they can be used for longer. Additionally, scientists can maintain these cells at very low temperatures, allowing them to continue using the same fetal cell lines that were isolated decades ago.
Despite the use of fetal cells in vaccine development, the resulting vaccines do not contain fetal cells or pieces of DNA that are recognizable as human DNA. During the purification process, cellular debris and growth reagents, including any remaining cellular DNA, are removed.

Vaccines do not contain fetal cells or DNA
Fetal cell lines have been used in the manufacture of vaccines since the 1930s. One of the first applications of cell lines derived from fetal tissues was in the production of the first polio vaccines. In the 1950s, scientists at the Karolinska Institute in Sweden propagated a polio virus in fetal cell lines to make a polio vaccine. The resulting vaccine was given to about 2,000 children.
Viruses need cells to grow and tend to grow better in human cells than in animal cells because they infect humans. Fetal cells were originally chosen because they were isolated from the sterile environment of the womb, meaning they would not be infected with other viruses, and the vaccine produced in these cells would not inadvertently introduce any other viruses.
However, it is important to note that vaccines do not contain fetal cells or DNA. While fetal cell lines may be used to grow vaccine viruses, the viruses are purified after growth, meaning the cellular debris and growth reagents, including any remaining DNA, are removed.
The use of fetal tissue in vaccine development has been a contentious issue, particularly for those with religious convictions. The issue of abortion is contentious, and some religious groups, such as the Roman Catholic Church and Southern Baptist Convention, oppose abortion and, thus, the use of fetal cell lines in vaccine development. However, several religious leaders from a variety of faiths have spoken in favor of vaccination. In 2017, the Pontifical Academy for Life stated that "clinically recommended vaccinations can be used with a clear conscience and that the use of such vaccines does not signify some sort of cooperation with voluntary abortion."
While some COVID-19 vaccines, such as the Johnson & Johnson vaccine, were developed using fetal cell lines, the final products do not contain fetal cells or DNA.

Fetal cells are isolated from the sterile environment of the womb
Fetal cells are isolated from the womb, which was previously believed to be a sterile environment. This belief was an accepted dogma for over a century. However, recent studies have challenged this notion by providing evidence of bacterial communities in the placenta, amniotic fluid, and meconium from healthy pregnancies. This suggests that the fetal environment may not be entirely sterile, and that microbiome acquisition could begin in utero.
The use of fetal cells in vaccine development involves growing viruses in cultured laboratory-grown cells derived from human fetal tissue. The practice of using fetal cells offers several advantages. Firstly, viruses need cells to grow, and they tend to grow better in human cells than in animal cells because they infect humans. Fetal cells, in particular, have not divided as many times as other cell types, allowing for longer usage. Additionally, the ability to maintain cells at very low temperatures enables scientists to continue using the same fetal cell lines isolated decades ago.
The most significant benefit of using fetal cells is that they are isolated from a relatively sterile environment, ensuring that the cells are not infected with other viruses. This prevents the inadvertent introduction of other viruses into the vaccine. Fetal cells were first used in the 1930s for the production of the polio vaccine and have since been used for vaccines such as chickenpox and rubella. The original fetal cells obtained from the 1960s continue to be used today, and no further sources of fetal cells are needed.
While the use of fetal cells in vaccines has been controversial due to their association with abortions, it is important to clarify that vaccines do not contain fetal cells or recognizable human DNA. The purification process ensures that any cellular debris and growth reagents, including cellular DNA, are removed. Fetal cell lines are also utilized during the testing and development phases of vaccines, contributing to the safety and effectiveness of medications.
In conclusion, fetal cells are isolated from what was previously believed to be the sterile environment of the womb, offering a key advantage in vaccine development by minimizing the risk of viral contamination. While recent studies have challenged the notion of a completely sterile womb, the use of fetal cells remains an important and well-established practice in vaccine creation and testing.

Vaccines derived from fetal cells include those against rabies, rubella, chickenpox, shingles, and adenovirus. The use of fetal tissue in vaccine development is a contentious issue, particularly on religious and moral grounds. The Catholic Church has encouraged its members to use alternative vaccines produced without human cell lines if possible. However, the Vatican has clarified that "vaccinations recognized as clinically safe and effective can be used in good conscience".
It is important to note that the vaccines themselves do not contain fetal cells or pieces of DNA that are recognizable as human DNA. When viruses grow in cells, the cells are killed, and the vaccine virus is purified to remove cellular debris and growth reagents. During this process, any remaining cellular DNA is broken down.

The Catholic Church has taken a stance against the use of fetal tissue in vaccines
Fetal cells have been used in the manufacture of vaccines since the 1930s. One of the first applications of cell lines derived from fetal tissues was in the production of the polio vaccine. Since then, many other vaccines, including those for chickenpox, rubella, rabies, shingles, and adenovirus, have been made using cell lines originally derived from fetal tissue. The COVID-19 pandemic brought tremendous publicity to the concern for vaccines associated with aborted fetal tissue, but the moral and ethical issues involved also apply to some routine childhood vaccinations and other adult vaccines.
In 2017, the Pontifical Academy for Life reiterated its stance, stating that "clinically recommended vaccinations can be used with a clear conscience and that the use of such vaccines does not signify some sort of cooperation with voluntary abortion." The Vatican has 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 while the Church discourages the use of fetal tissue in vaccines, it does not consider it a sin to receive such vaccines if there are no alternative options.
In response to the COVID-19 vaccines, The United States Conference of Catholic Bishops (USCCB) published documents emphasizing the avoidance of vaccines associated with aborted fetal tissue. However, they permit the use of vaccines with remote associations with evil if there are no alternatives and the intent is to preserve life. The Vatican has made similar statements, emphasizing that Catholics can use their discernment and choose to be vaccinated with clinically safe and effective vaccines, even if they are connected with cell lines derived from aborted fetal tissue.
It is important to note that while the Catholic Church encourages alternative vaccines, it does not consider it a sin to receive vaccines derived from fetal cell lines if there are no other options. This position considers the potential impact on public health and the duty to protect others. Religious leaders from various faiths, including Catholicism, have spoken in favor of vaccination, and alternative vaccines that are not developed using fetal cell lines are available for those who choose to avoid them.
