The use of aborted fetal tissue in vaccine development has been a controversial topic, with some people raising ethical concerns about the practice. It is true that certain vaccines, such as the chickenpox vaccine, have been produced using fetal tissue from abortions. The WI-38 and MRC-5 cell lines, derived from fetal lung tissue, are commonly used in vaccine development and have been for decades. In recent times, the COVID-19 vaccines have also faced scrutiny over their use of fetal cell lines during the production phase. While fact-checkers have labelled claims of aborted fetus in COVID-19 vaccines as false, the use of fetal cell lines in vaccine development is an established practice. The moral implications of this practice have sparked debates, with some pro-life organizations advocating for alternatives that do not involve the use of aborted fetal tissue.

The chickenpox vaccine is made with human embryonic lung cell cultures from aborted foetuses
The WI-38 cell line was obtained from the lung tissue of a 12-week-old female foetus aborted in 1961. The MRC-5 cell line was derived from lung tissue taken from a 14-week-old male foetus aborted in 1966. These cell lines are now more than three generations removed from their origin, and no new tissue has been used to produce these vaccines.
The use of aborted foetal tissue in vaccine development is a controversial issue, with some people choosing to exempt their children from vaccinations on religious grounds. However, religious leaders and bioethics experts have stated that the distant connection to abortion does not outweigh the public health benefits of vaccination.
The chickenpox vaccine is safe and effective at protecting against chickenpox, and it is recommended that individuals receive two doses of the vaccine for full protection.

COVID-19 vaccines were tested on mice with human fetal lung tissue
The use of human fetal tissue in vaccine development has been a topic of debate and controversy. While some people object to the use of aborted fetal tissue on moral grounds, others argue that it is necessary for medical research. In the case of COVID-19 vaccines, there have been claims that they were tested on mice with human fetal lung tissue.
In 2019, a clinical study was conducted at the University of North Carolina-Chapel Hill by Ralph S. Baric and his team. They genetically engineered two mice models, the humanized Lung-Only Mice (LOM) and the BLT-L (bone marrow-liver-thymus-lung) mice, to test vaccines and therapeutics for respiratory diseases, including coronavirus. The LOM model was created by implanting small pieces of human fetal lung tissue onto immunodeficient mice, while the BLT-L model was constructed by implanting human fetal thymus, liver, and lung tissue. These models were touted as being particularly useful for vaccine testing.
Following the University of North Carolina study, other research institutions also utilized humanized mice models with human fetal lung tissue to study COVID-19. The Institut Pasteur in France, for example, worked on the "Modeling Human SARS-COV2 Infection in Mice with Human Lung Xenografts" project, constructing the HuLung and HIS-HuLung mice models. Similarly, the University of Saskatchewan produced a continuous supply of Ralph Baric's Lung Only precision mice model using fetal lung tissue for COVID-19 research.
It is important to note that the use of humanized mice engrafted with human fetal organs in COVID-19 vaccine research is not limited to lung tissue. For example, Yale researchers in a Regeneron laboratory used human fetal liver tissue to engineer a mouse model for testing monoclonal antibody drugs. Columbia University also offered mice models humanized with human fetal thymus tissue for COVID-19 research.
While there have been claims that COVID-19 vaccines contain aborted fetal cells, fact-checking organizations have labeled these claims as false. However, it is true that some COVID-19 vaccines, such as AstraZeneca's, were developed using aborted fetal cell lines. These cell lines were used as a growth medium for the virus during the production phase, and the resulting vaccines do not literally "contain" these cells. The use of human fetal tissue in COVID-19 vaccine development, including in mice models, has provided valuable insights into the disease and contributed to the development of effective vaccines and therapeutics.

AstraZeneca's COVID-19 vaccine is made using aborted fetal cell lines
The use of fetal tissue in vaccine development is the practice of researching, developing, and producing vaccines through growing viruses in cultured (laboratory-grown) cells that were originally derived from human fetal tissue. Since the cell strains in use originate from abortions, there has been opposition to the practice and the resulting vaccines on religious and moral grounds. The vaccines do not contain any of the original fetal tissue or cells or cells derived from fetal materials. Although the vaccine materials are purified from cell debris, traces of human DNA fragments remain.
AstraZeneca's COVID-19 vaccine, ChAdOx1 nCoV-19, is one of several COVID-19 vaccines that have been developed using aborted fetal cell lines. The vaccine was developed in the HEK 293 cell line, which was derived from embryonal kidney tissue from a fetus aborted in the 1970s. The use of fetal cell lines in the development of the AstraZeneca vaccine has been a source of ethical concerns and hesitancy among individuals with religious convictions. Some fact-checking organizations have labelled claims about the presence of aborted fetal cells in the vaccine as false, but others argue that these fact-checkers are relying on semantics.
The Catholic Church has historically opposed abortion and encouraged its members to use alternative vaccines produced without human cell lines. However, in 2017, the Pontifical Academy for Life stated that "clinically recommended vaccinations can be used with a clear conscience" and that their use does not signify cooperation with voluntary abortion. In December 2020, the Vatican's Congregation for the Doctrine of the Faith further clarified that it is "morally licit" for Catholics to receive vaccines derived from fetal cell lines, especially during the COVID-19 pandemic, as there is a "grave danger" posed by the virus.
While the use of aborted fetal cell lines in vaccine development remains controversial, it is important to note that these cell lines have been used in medicine since the 1930s and have contributed to significant advancements, including the development of the polio vaccine. Additionally, alternative vaccines that are not designed, developed, or produced using fetal cell lines, such as mRNA vaccines, are available for individuals who object to the use of aborted fetal cells.

The WI-38 cell line came from a fetus aborted in 1961/1962
The WI-38 cell line is a diploid human cell line composed of fibroblasts derived from lung tissue. The cell line was developed from the lung tissue of a 12-week-old female fetus aborted in 1961 or 1962 in Sweden. The abortion was performed legally, and the fetus was not aborted for the purpose of vaccine development. The WI-38 cell line was isolated by Leonard Hayflick in 1962, and it has been used extensively in scientific research and vaccine development. Hayflick discovered that many viruses, including rubella, grew well in the WI-38 cell line and that it was safe for human vaccines.
The WI-38 cell line is estimated to have saved millions of lives through its use in human virus vaccine production. It is one of the first cell lines to have its diploid genome sequenced, which is critical for understanding genetic variants. The cell line has been shown to retain its genetic stability even nearly 60 years after its establishment, as demonstrated by karyotyping in 2020.
The WI-38 cell line is not the only one derived from aborted fetuses that is used in vaccine development. Other commonly used cell lines include HEK293, MRC-5, and PER.C6, which were derived from fetuses aborted in 1972, 1966, and 1985, respectively. The use of fetal cell lines in vaccine development has raised ethical concerns for some individuals and groups, especially those with moral objections to abortion.
It is important to note that the original fetal cells were obtained almost 40 years ago, and the descendant cells are used as a medium for vaccine preparation. The NCBC, a Catholic organization, has encouraged pharmaceutical companies to develop future vaccines without the use of these cell strains. However, others argue that the risk to public health of not vaccinating outweighs the concern about the origins of the vaccines.

The MRC-5 cell line was developed from lung tissue taken from a 14-week-old fetus aborted in 1966
The MRC-5 cell line, also known as the Medical Research Council cell strain 5, is a diploid human cell culture line. It was developed by J.P. Jacobs and colleagues at the Medical Research Council in the UK in 1966. The cell line was derived from lung tissue taken from a 14-week-old male fetus aborted for psychiatric reasons from a 27-year-old physically healthy woman. The tissue was obtained through a process involving cell culture techniques, and the resulting cells exhibit a fibroblast-like morphology.
The MRC-5 cell line has become a cornerstone in the field of antiviral research and vaccine development. These diploid cell strains are integral to the production of the rubella virus vaccine and the Sabin poliovirus vaccine. The derivation of the MRC-5 cells from human tissue makes them an exceptional model for studying viral behaviours, such as the replication of poliovirus, the mechanisms of SARS-CoV amplification, and the generation of the herpes simplex virus. Their susceptibility to various viruses has streamlined vaccine development, providing a reliable cell substrate for virus replication, including for viruses that cause measles and rubella.
The non-cancerous nature of MRC-5 cells is vital to vaccine safety, as it ensures that the response observed in these cells is indicative of what would occur in human cells. This makes MRC-5 cells a preferred choice for vaccine development and testing. The cell line's ability to support virus growth and its non-cancerous nature distinguish it from other cell lines derived from different sources.
The use of fetal tissue in vaccine development has been a controversial topic, with some individuals and organizations expressing objections based on moral and ethical grounds. However, it is important to note that the MRC-5 cell line was derived from tissue obtained in 1966, and the original fetus is not "alive" or "growing" in any form within the vaccine. The cells used in vaccine development are cultured and grown separately, and they do not contain the original fetal tissue.
While the use of aborted fetal tissue in vaccine development may be objectionable to some, it is crucial to understand the scientific and medical context in which it occurs. The use of these cells has significantly contributed to advancements in antiviral research and vaccine development, ultimately helping to protect people's health and well-being.
