What are MRC-5 and WI-38? And Why Are They In Vaccines?

    1. “What are MRC-5 and WI-38?  And Why Are They In Vaccines?”
    2. MRC-5 DNA:
      “The MRC-5 cell line was developed in September 1966 from lung tissue taken from a 14 week fetus aborted for psychiatric reason from a 27 year old physically healthy woman. The cell morphology is fibroblast-like. The karyotype is 46,XY; normal diploid male. Cumulative population doublings to senescence is 42-48. G6PD isoenzyme is type B.

  • Sound Choice Pharmaceutical Institute (Soundchoice.org) presentation (2008) to include information about human DNA in vaccines:
    “Vaccine Manufacturing Contaminants You Have Not Been Told About and Autism”

    The whole presentation is important and should be read carefully.  One slide that caught my eye on page 4 – and made me GASP:

    “The Rubella component of the MMR II contributes over 150 ngs of human fetal DNA fragments at the PERFECT SIZE FOR INSERTIONAL for MUTAGENESIS TO OCCUR.

    Mutagenesis – The induction of genetic mutation; Production of genetic ALTERNATION through use of CHEMICALS or RADIATION.

    Insertional Mutagenesis: Mutation caused by insertion of NEW GENETIC MATERIAL into a normal gene, particularly of retroviruses into chromosomal DNA.

    Vaccines manufactured using the WI-38 cell line are contaminated with retrovirus (fragment of HERVK).

    Retrovirus:  Any virus of the family Retroviridae. A virus (infection-my word) with RNA core genetic material; requires the enzyme reverse transcriptase to convert its RNA into proviral DNA.

    HERV – Human endogenous retroviruses
    “HERVs are the remnants of ancient retroviral INFECTIONS (the article’s word), sometimes called fossil viruses.  HERVs provide us with an important link to our distant ancestors and illustrate how, from our basic understanding of our genome, our biological blueprint is turning out to be even more complicated than anyone could have ever imagined.”
