New Human Fetal Cell Line Available for Vaccine Production

“The tissues from the freshly aborted fetuses were immediately sent to the laboratory for the preparation of the cells.” — Bo Ma et al.

Since the 1960s, a number of vaccines have been manufactured using “human-diploid fibroblast cell cultures”—cells from tissue of aborted human fetuses.1 2 3 4 5 They include the following 11 vaccines listed on the Centers for Disease Control and Prevention’s (CDC) Vaccine Excipient & Media Summary table:

  • Adenovirus
  • DTaP-IPV/Hib (Pentacel)
  • DTaP-IPV (Quadracel)
  • Hep A (Havrix)
  • Hep A (Vaqta)
  • Hep A/Hep B (Twinrix)
  • MMR (MMR-II)
  • MMRV (ProQuad)
  • Rabies (Imovax)
  • Varicella (Varivax)
  • Zoster (Shingles – Zostavax).6 

The aborted human fetal cell cultures are used for growing viruses, which are then used in the preparation of inactivated and live virus vaccines. Viruses for vaccines are also grown on other kinds cultures such as chicken embryos or from cells from different animals and bugs, such as army worms, but, according to the National Network  for Immunization Information (NNii), “human cells are preferred because cells derived from animal organs sometimes may carry animal viruses that could harm people.”1 5 7 8 9 10

There are two specific human cell lines that are used in vaccine production. The first one is known as the Wistar Institute-38 or “WI-38″. The second is the Medical Research Council -5 or “MRC-5″.

The WI-38 cell line was developed in July 1962 from “lung tissue taken from a therapeutically aborted [female] fetus of about 3 months gestational age.” The MRC-5 cell line was developed September 1966 from “lung tissue taken from a 14 week [male] fetus aborted for psychiatric reason from a 27 year old physically healthy woman.”3 4 

According to Joseph Mercola, DO, WI-38 and MRC-5 are the two “primary cell cultures” that have been used to make hundreds of millions of doses of vaccines for more than half a century.10 However, there is now a third aborted human fetal cell culture that may be used. It is called Walvax-2, and it has been assessed as a culture for growing rabies, hepatitis, and Varicella viruses.11

A study published in the journal Human Vaccines & Immunotherapeutics in 2015 confirmed the development of Walvax-2 by China’s pharmaceutical industry. The source tissue for the cell line was obtained from nine fetuses through “rigorous screening based on carefully specified inclusion criteria.”11 

The study’s authors noted, “The tissues from the freshly aborted fetuses were immediately sent to the laboratory for the preparation of the cells.”

The Walvax-2 strain of cells met all of these criteria and proved to be the best cell line following careful evaluation. Therefore it was used for establishing a human diploid cell strain. Walvax-2 was derived from a fetal lung tissue, similar to WI-38 and MRC-5, and was obtained from a 3-month old female fetus aborted because of the presence of a uterine scar from a previous caesarean birth by a 27-year old healthy woman.11

The source tissue was provided by Department of Obstetrics and Gynecology of Yunnan Hospital in China.11 Relatively little additional information about Walvax-2 is available from public sources. It is not clear, for example, how the name was derived or what government agency or company is leading the research and the possible application of the cell line to vaccine production.

It is worth noting, though, that there is a major vaccine manufacturer called Walvax Biotechnology Co., Ltd. in the city of Kunming in the Chinese province of Yunnan. It is a private firm whose products include haemophilus influenza type b conjugate vaccines, meningococcal polysaccharide conjugate vaccines, and blood products.12 13

    I have used the following website to learn more on the aborted fetal tissue used in vaccines:
    It has a wealth of information on this topic and I would recommend it to anyone who has concerns on this subject.

    The tissues were obtained from a live aborted fetus! “They further noted how they induced labor using a “water bag” abortion to shorten the delivery time and prevent the death of the fetus to ensure live intact organs which were immediately sent to the labs for cell preparation.” http://vaccineimpact.com/2015/new-fetal-cell-line-from-live-abortion-emerges-for-vaccine-production/

    I am amazed that the ‘religious right’ (and organized religion in general) has never made an issue of the fact that vaccines are grown on aborted human tissue. Surely they would dissuade their followers from accepting vaccines purely on religious grounds… or have they been persuaded to turn a blind eye?

      Just because you haven’t heard our protests doesn’t mean they haven’t been there. The battle against abortion and the use of fetal tissue is enormous and ongoing. Do something to help.

      Since Vatican 2, the Catholic church probably doesn’t care about these types of things as many so-called Catholic charities refer women to Planned Parenthood for abortions and as you have noticed really don’t do anything on the whole about abortion at all even for their church members. The real catholic church consists of the resistance who follow church teachings before Vatican 2 which is Masonic.

        This is a bizarre comment. As a Catholic theologian, I am shocked at this statement. The church’s stance on abortion has always been clear: both before and after Vatican II. Masons are not Catholics! Masons are a movement of “stone-cutters” and in general do not adhere to any particular denominational beliefs.

    Suzie…….bingo. There’s diet implications, environmental, air, water, toxins also, but, bingo. Look 3 comments above yours. putting someone elses DNA into your own body is a prescritption for disaster. We can all reverse what’s going on with our bodies with changing what’s on the end of our fork. Stop eating ourselves to death and vaccines wouldn’t be necessary! (they’re really not anyway and are what’s causing all this crap,,,,but.)

    We should all be very leery of anything such as this being developed by China.

    In response to Judy Fenton’s comment, I’ve been wondering for years, what’s the difference between a 3 month old gestational “cell” and/or a 3 month old gestational “stem cell”?

    Also, has anyone considered blood types or gender.

    Thanks for the links, I’ll be sure to check them out.

    I am old enough to be born before mass vaccination. I had a few as a child, and again some when i immigrated. There are a bunch of new illnesses around we never heard of before mass vaccination, the enormous amount of pesticides and the messing with genetic materials. I have a feeling that humans are little by little destroying themselves in the name of progress.

    Could the real reason for the abortion of the child listed for the Walvax 2 strain be China’s One Child Policy?

    It is wrong to use tissue from aborted babies. It’s very wrong to use this tissue’s cell lines to produce vaccines for babies, because there is residual human DNA in the actual vaccines. This human DNA can integrate into the baby’s own genome, causing mutations to the nervous system resulting in autism. Dr. Theresa Deisher of Sound Choice Pharmaceutical Institute in Seattle, WA has spent years researching this. She has found a clear correlation between use of the fetal DNA vaccines and autism. Please look at these two websites: http://www.soundchoice.org and http://www.verifyyourvaccines.com.

    It was just a matter of time… but now they can’t use the argument that no new fetal cells have been harvested. And unless minds and hearts accept the truth of the evil of killing babies in the womb, there will inevitably be more fresh human unborn baby cells used for human medications, while science and medical professions will remain in denial as to why strange and new illnesses increase, along with increased occurrences of allergies, autism, and more.

      Thank you for these links! I’m very much against vaccines anyway, and believe them to be dangerous for multiple reasons. But I had never yet heard that it is the “human fetal contaminants in the vaccines that are associated with autism”. This information must be really being suppressed!

    Interesting that Walvax 2 was said to have been derived from 9 fetuses but yet the description of the cell line mentions only one dead baby. What about the abortion stories for all the other contributing fetuses? Would like more info on this, perhaps Cogforlife.com will run a feature on this. Thanks for your info

    In regards to the 4th paragraph…”The WI-38 cell line was developed in July 1962 from “lung tissue taken from a therapeutically aborted [female] fetus of about 3 months gestational age.” The MRC-5 cell line was developed September 1966 from “lung tissue taken from a 14 week [male] fetus aborted for psychiatric reason from a 27 year old physically healthy woman.”3 4

    My question is could there possibly be unknown implications on societies that are injected with the genetic materials of other humans, not limited to the scientifically known physical harms, but also including the possibility of mental harms from being injected with genetic materials derived from psychiatric patient’s discarded offspring, such as the MRC-5? It would explain a lot.
