Despite persistent claims to the contrary, none of the 3 approved COVID-19 vaccines involve fetal tissue.
At an early stage of development, two of the coronavirus vaccines, the Pfizer/BioNTech and Moderna mRNA vaccines, were tested on mobile lines manufactured long ago from an aborted fetus. And Johnson’s vaccine
However, none of the vaccines provide fetal cells or fetal tissue, and no new abortion has bothered to achieve any aspect of the vaccines. Many devoted teams and anti-abortion organizations have said it is not morally reprehensible to get at least some of the available COVID-19 vaccines.
Confusion about the role of fetal cells or tissues, or lack thereof, with COVID-19 vaccines has erupted because of Supreme Court Justice Clarence Thomas.
In a dissenting opinion issued on June 30, Thomas referred to the petitioners’ objections in a case involving a New York State mandate for physical care personnel to be vaccinated against COVID-19.
“The petitioners are 16 health care staff members who have served New York communities during the COVID-19 pandemic,” Thomas wrote. “They are fervently opposed to all COVID-19 vaccines being developed using mobile lines derived from aborted children. “
Several media outlets pointed to Thomas’ comments, with some suggesting he made a factual mistake or spread false facts about vaccines. It is known to what extent Thomas simply summarized the petitioners’ point of view, or whether he agreed with the sentiment.
Leaving aside the question of when a fetus in gestation deserves to be characterized as a child, Thomas is right. He is careful to say “developed” rather than manufactured, and does not claim that any of the vaccines involve fetal cells, even though some other people have had this mistaken impression of their dissent.
Still, it’s worth offering context for understanding what fetal mobile lines are, how they relate to COVID-19 vaccines, and how it compares to other vaccines, medical products, and clinical research.
As explained above, the fetal mobile lines used to test, develop, or produce certain vaccines are distinct from fetal tissue, and no vaccine contains fetal tissue. But some vaccines, in addition to some of the world’s most popular vaccines for the formative years, have a connection to lab-created mobiles that were originally made from mobiles extracted from an aborted embryo or fetus.
Two of the most widely used mobile strains in vaccine progression or manufacture are MRC-5 and WI-38, which were made decades ago from lung tissue extracted from two other aborted fetuses in the UK and Sweden in the 1960s. Researchers have found that mobile phones are useful for this goal because they are clever in developing viruses that infect humans, and many vaccines are made from weakened viruses.
The rubella vaccine, for example, which is a component of the measles, mumps, and rubella vaccine, or MMR, is still manufactured today by developing gigantic amounts of WI-38 cells. The weakened rubella vaccine virus also evolved by passing the virus to cells at a temperature lower than that of the human body. This meant that the virus could be reflected enough to generate lasting immunity to the vaccine, but not enough to make a user sick.
Other vaccines produced in mobile fetal lines come with chickenpox, hepatitis A and one of the rabies vaccines. As children’s Hospital of Philadelphia explained, vaccines manufactured on mobile fetal lines involve any of the mobiles because the vaccines are purified.
Only one of the COVID-19 vaccines in the United States is manufactured by developing the virus on a fetal mobile line.
Johnson’s Least Used Vaccine
According to the Children’s Hospital of Philadelphia, the cells are derived from retinal cell isopast due to an aborted fetus in 1985. The cells then adapted to develop replication-deficient adenoviral vaccines in the late 1990s.
The Pfizer/BioNTech and Moderna vaccines, which do not involve viruses and are composed of messenger RNA, have a weaker link to fetal mobile lines. None of the vaccines are manufactured on such mobiles, but corporations have conducted some experiments to test their vaccines on HEK-293T Mobiles, which are commonly used in biomedical research.
HEK-293T are human embryonic kidney cells, derived from cells extracted from a fetus in 1973. It is known whether this fetus had a miscarriage or abortion, according to a document from the North Dakota Department of Health.
In particular, the scientists used HEK-293T cells so that the vaccine’s mRNA can be converted into complex SARS-CoV-2 proteins, and also used the cells to create SARS-CoV-2 pseudoviruses to verify the effectiveness of antibodies in vaccinated patients. animals. neutralize the virus. Alessondra Speidel, a biomaterials scientist at Sweden’s Karolinska Institutet, told National Geographic that such controls resemble a proof-of-concept control, as it appears that the design of the mRNA works.
As noted through the North Dakota Department of Health, the Catholic Church, and southern Baptist Ethics
In addition, even the Charlotte Lozier anti-abortion institute considers the Pfizer/BioNTech and Moderna vaccines to be “ethically uncontroversial. “
Although the use of fetal mobile lines in some vaccines has long been debatable for some people, it should be noted that those mobiles are commonly used in all kinds of fundamental biomedical research, and that these paintings underpin much of scientists’ understanding of human biology and disease. .
Fetal mobile lines are also used to identify new remedies for various diseases and to conduct studies on various non-unusual drugs, adding paracetamol or Tylenol.
Several COVID-19 treatments, such as monoclonal antibodies and the antiviral drug remdesivir, have also been tested on fetal mobile lines.
“A lot of other people don’t realize how critical fetal mobile lines are to getting critical drugs and vaccines they depend on every day,” Amesh Adalja, an infectious disease expert at the Johns Hopkins Center for Health Security, told National Geographic. “Its use in the progression of COVID-19 vaccines is neither other nor special. “
According to one estimate, in 2015 more than 10. 3 million lives were saved with the use of vaccines produced with WI-38 cells alone, and 4500 million diseases were prevented or treated.
Less than a week earlier, the court had overturned Roe v. Wade. Wade, the case that gave Americans the constitutionality of abortion.

Q. Are other vaccinated and vaccinated people more likely to become inflamed or have the omicron variant than other unvaccinated people?
R. Non. Se vaccinated increases their coverage against COVID-19. Sometimes some basic knowledge might recommend otherwise, but this data cannot be used to evaluate the efficacy of a vaccine.
