I have some questions about human tissue/product used to make some vaccines.


I understand that it is preferable? to use human tissues as with animal there are some concerns about cross-species contamination – like SV40 or current pig viruses in Rota vaxes.


This and Mercola ( (take it or leave it!!!)


Put the following vax as using fetal tissue and/or containing DNA, protein, etc from fetal tissue: Injected Polio, MMR, Varicella, Hep A, and Rabies, including the combos some of those are part of.


As far as I understand, it is not literally tissue from an aborted fetus, but is DNA from a fetus which was aborted.



Human diploid cells are batches of human cells grown in a laboratory….


Two different strains of human diploid cell cultures made from fetuses have been extensively used extensively for vaccine production for decades. One was developed in the United States in 1961 (called WI-38) and the other in the United Kingdom in 1966 (called MRC-5)….


WI-38 came from lung cells from a female fetus of 3-months gestation and MRC-5 was developed from lung cells from a 14 week-old male fetus. Both fetuses were intentionally aborted, but neither was aborted for the purpose of obtaining diploid cells.


… The WI-38 and MRC-5 cell cultures have been used to prepare hundreds of millions of doses of vaccines, preventing millions of cases of rubella, hepatitis A, varicella, and rabies.

(Report by a former senior scientist at pharma company speculating that human DNA in MMR and Varicella vaxes could be a factor in autism) -



...the rubella component of MMR II was propagated in a human cell line derived from embryonic lung tissue (Merck and Co., Inc., 2010). The MMR II vaccine is contaminated with human DNA from the cell line...


...the chicken pox vaccine was grown in human fetal tissue (Merck and Co., Inc., 2001; Breuer, 2003)


The human DNA from the vaccine can be randomly inserted into the recipient’s genes by homologous recombination, a process that occurs spontaneously only within a species. Hot spots for DNA insertion are found on the X chromosome in eight autism-associated genes involved in nerve cell synapse formation, central nervous system development, and mitochondrial function (Deisher, 2010). This could provide some explanation of why autism is predominantly a disease of boys. Taken together, these data support the hypothesis that residual human DNA in some vaccines might cause autism.


So, am I wrong in understanding that while no tissues/substance from an actual aborted fetus is in any vaccine - the DNA in these vaccines is the DNA from the original aborted fetuses?


And if so, I would like to have more information about what specifically about the production of these vaxes makes it impossible to filter out this DNA and proteins, cell debris, etc.


(for the record, I am not asking about this from the pro-life/pro-choice perspective, I want to know more about this DNA present in vaccines, and also, it seems people are quickly dismissed when they state vaccines contain tissue from aborted fetuses... which is true... technically... it is just the DNA? If I am grossly wrong here, please correct!)

Ok, well it was pointed out to me that this was discussed here recently:


So I guess we can say then that vaccines contain DNA from aborted fetuses... NOT aborted fetal tissue.

Although aborted fetal tissue was technically used in the vaccine production.


I don´t understand enough about the production process to know why that could not be filtered out. Does anyone have a good site for explanation?

Is DNA always in these vaccines, or just some, sometimes?

Looks like the Vaqta brand (Merck) for Hep A also has DNA.


Ratajczak pointed towards trends in autism after MMRII and Varicella introduction to vax schedule. (Her article also discusses various other theories/combo of theories). Hep A was added in 2005/6 for everyone, prior had just been those living in high risk areas. I wonder how long it will take to get information about another autism surge in regards to that? - But didn't they trying to change guidelines in diagnosing autism? to reduce cases? I don't follow the issue that closely?
