Ah... ok. Eh... still creepy to me. Though I'd find it just as creep if they were using animal cells. That's just me.
No, no worries! It's not an easy concept, and we're also sort of talking about two different things. The viruses used in the vaccines have to be cultured on a cell line. The cell line is from an aborted fetus. The cell line certainly has DNA and they know what fetus it came from. However, the vaccine itself contains no fetal tissue, DNA, or anything like that.
Well, at least one expert feels that there is a serious issue with DNA in vaccines:
"Ratajczak also looks at a factor that hasn't been widely discussed: human DNA contained in vaccines...about the same time vaccine makers took most thimerosal out of most vaccines (with the exception of flu shots which still widely contain thimerosal), they began making some vaccines using human tissue...human tissue is currently used in 23 vaccines. She discusses the increase in autism incidences corresponding with the introduction of human DNA to MMR vaccine, and suggests the two could be linked...an additional increased spike in autism occurred in 1995 when chicken pox vaccine was grown in human fetal tissue."
Dr. Ratazjczak is, interestingly, a former senior scientist at Boehringer Ingelheim Pharmaceuticals, Inc.
Here are links to her restrospective studies:
In "An Interview With Dr. Helen Ratazjczak" (http://holyhormones.com/womens-health/hormones/estrogen/autism’s-causes-and-biomarkers-an-interview-with-helen-ratajczak-ph-d/), she is quoted as saying, "The MMR II vaccine is contaminated with human DNA from the cell line in which the rubella virus is grown. This human DNA could be the cause of the spikes in incidence. An additional increased spike in incidence of autism occurred in 1995 when the chicken pox vaccine was grown in human fetal tissue (Merck and Co., Inc., 2001; Breuer, 2003)."
She offers an explanation of how this can be be linked with vaccines:
"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.”
Vactruth.org did a 3-part interview with Dr. Ratajczak:
1995 is when they moved the first MMR dose in the US to 12-15 months, and started pushing a second dose 1 month later. In addition, schools ask for a "second" dose before entering school, and I had many friends in the late 1990's and early 2000's whose kids ended up getting a THIRD MMR before kindergarten, either not realizing that their child HAD had 2 MMRs, or because the school "required" a second one upon entrance, or "just to be safe."
The rubella component, by the way, is derived from human embryonic lung tissue.
1995 is also when the chicken pox vaccine was introduced. It looks to me like she is ascribing the 1995 spike to the addition of the chicken pox vaccine, not to the MMR.
