Are Vaccinations Ethical?

I talked with the chaplain last week about a number of things, including vaccinations and I wanted to share what I have learned in some of my research. There are certain types of them that I believe are unethical and I will not take them. I realize that a topic like vaccinations could get rather heated. This is a matter of conscience - good Christian people could disagree about the ethical concerns of using this type of vaccination. I think it may be possible for Christian people to both use them with a good conscience, but the information should still be put out there for people to make their own decisions.

In a number of vaccines human cell lines are used (usually as the culture to grow the virus in). Both of the lines used are originated from murdered unborn babies.

On the CDC website itself are the following two documents:



These are both directly on the CDC website and can be found by searching for "excipient" on their website.

The second document looks like it was actually composed in 2012. It lists recent vaccines that were made with MRC-5 and WI-38 human diploid tissue. A mere google search will turn up the following about these tissue lines:

"MRC-5 (Lung, diploid, human)

"Derived from normal lung tissue of a 14-week-old male fetus by J. P. Jacobs in September 1966 (Nature 227: 168-170, 1970), the MRC-5 cell line was established in a growth medium consisting of Earle's Basal Medium in Earle's balanced salt solution supplemented with 10% calf serum. Following initial cultivation, subcultures were prepared twice weekly at a 1:2 ratio. When the cells reached approximately the 7th population doubling, the majority of the cultures were harvested to prepare a frozen cell stock. Subsequent observations revealed that the MRC-5 cells are capable of attaining 42-46 population doublings before onset of the decline in proliferation usually experienced with human fibroblast lines. The MRC-5 cell strain (like the WI-38 cell line) is susceptible to a wide range of human viruses." (http://www.viromed.com/services/product/mrc5.htm)

(Lung, diploid, human)

"The WI-38 human diploid cell line was derived by L. Hayflick from normal embryonic (3-month gestation) lung tissue of a female (Exp. Cell Res. 25: 585, 1961). The growth medium used was Eagle's medium in Earle's balanced salt solution supplemented with 10% calf serum. The cells have a finite lifetime of 50 (plus or minus 10) population doublings with a doubling time of 24 hours (Exp. Cell Res. 37: 614, 1965). The cell line has been shown to have one of the broadest human virus spectra of any cell population that has been tested and is especially useful for isolation of rhinoviruses."

Notice they have their own citation for where this cell line originates. I have no way to check theirs, but the information can found on other pages, and is not from a page that is in anyway biased against the use of such cells. (Not that bias is bad.)
