The most sensational internet claim must be dismantled upfront: there are no fetal tissues, body parts, or cellular fragments in a vaccine vial.

Really. Well I am not so sure of that. 

How can we know for sure because the vaccine makers are no longer required to publish the ingredients in the safety data sheet.

Vaccines used in the U.S. that are made by growing the viruses in fetal cells include: 

• Varicella (chickenpox) 
• Rubella (the “R” in the MMR vaccine)
• Hepatitis A
• Rabies (one version, called Imovax)

The chikungunya vaccine, Vimkunya, is made by putting the genes for three proteins from the virus into human embryonic kidney cells (called HEK-293). As the cells reproduce in the lab, the proteins are produced. They are then purified for use in the vaccine.

The COVID-19 made by Johnson & Johnson (J&J)/Janssen also used fetal cells in production, but this vaccine is no longer used in the U.S. 

Questions about fetal cells and vaccines tend to focus on two areas: 

• Whether the use of human cells to make vaccines can cause harm, specifically because of the potential for exposure to human DNA
• Whether it is acceptable to use a vaccine made using fetal cells as related to one’s religious beliefs

About fetal cells used to make vaccines

The decision to grow vaccine viruses in fetal cells was not made lightly. Science often progresses by overcoming roadblocks. In this case, fetal cells helped scientists overcome two important considerations:

1. Viruses reproduce in cells, so one of the necessary “tools” is a type of cell in which the virus will grow. Viruses will not grow in just any cell type, so one of the first things a scientist needs to do is to figure out what cells the virus will infect in the lab. First, they need to grow the virus to study it. Later, viral growth may be necessary to make a diagnostic test or vaccine to help identify or prevent infections. Because viruses infect people, human cells can be a useful solution.
2. Another consideration is that scientists only grow the virus they are interested in studying or using. Here, fetal cells offer a benefit over other types of human cells. Specifically, because they were only exposed to the sterile environment of the womb, fetal cells are unlikely to be infected with other viruses. So, a vaccine produced in these cells would not be contaminated with any other viruses. This was an important consideration in the 1960s because a contaminating virus, called SV40, had been found in the polio vaccines developed in the 1950s. While SV40 did not cause harm to those who were exposed, it was something that scientists wanted to make sure did not happen again. Fetal cells removed this concern.

Fetal cells also offered another benefit that was understood by scientists at the time. Almost all cells die after they have divided a certain number of times. Scientifically, this number is known as the Hayflick limit. For most cell lines, including fetal cells, it is around 50 divisions. Because fetal cells have not divided as many times as other cell types, they can be used longer. In addition, because of the ability to maintain cells at very low temperatures, such as in liquid nitrogen, scientists can continue using the same fetal cell lines that were isolated in the 1960s. In the lab, cellular divisions are counted and long-term storage is important for maintaining cell lines. This work is referred to as cell passage. Cell passage is discussed in more detail on the webpage, “Stanley Plotkin: Pioneering the use of fetal cells to make rubella vaccine.”

Types of fetal cells used

Most vaccines made using fetal cells are made using fibroblast cells. Two exceptions are the COVID-19 vaccine (J&J/Janssen), which is made using fetal retinal cells, and the chikungunya vaccine, which is made using fetal kidney cells.

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.^[1] Since the cell strains in use originate from abortions,^[2] there has been opposition to the practice and the resulting vaccines on religious and moral grounds.^[1][3][4]

A peer-reviewed paper by Deisher et al titled, Epidemiologic and Molecular Relationship Between Vaccine Manufacture and Autism Spectrum Disorder Prevalence, delivered one of the most alarming findings in modern vaccine safety research: childhood vaccines grown in human fetal cell lines contain billions to trillions of fragmented human DNA molecules—capable of entering and integrating into the genome of human cells.

Summary: The use of fetal tissue from elective abortions is commonplace in the pharmaceutical industry and in medical research. This opinion addresses the licitness, quasi-benefits, and consequences of using fetal tissue from elective abortions in vaccines and in medical research. All people of good conscience have the responsibility to voice opposition to the use of fetal tissue from elective abortions in order to promote development of alternatives, affirm the value of all human life and limit scandal.
