Do Vaccines Contain Aborted Fetal Tissue?

Question: Do Vaccines Contain Aborted Fetal Tissue?
Some parents reject vaccines on the basis that vaccines might cause autism. Some parents reject vaccines on the basis that vaccines contain aborted fetal tissue. Is this really true?
Answer: Vaccines contain no aborted fetal tissue.

But there's more to the story.

Some vaccines, including the Mumps Measles Rubella (MMR) vaccine, contain killed viruses. The viruses are cultured in aborted fetal tissue. Regarding the MMR vaccine, the CDC states:

    The rubella vaccine virus is cultured in human cell-line cultures, and some of these cell lines originated from aborted fetal tissue, obtained from legal abortions in the 1960's. No new fetal tissue is needed to produce cell lines to make these vaccines, now or in the future. Fetal tissue is not used to produce vaccines; cell lines generated from a single fetal tissue source are used; vaccine manufacturers obtain human cell lines from FDA-certified cell banks. After processing, very little, if any, of that tissue remains in the vaccine.
So if there is any tiny residual cellular material in a vaccine, it is from cell lines. Although those cell lines originated in aborted fetal tissue decades ago, there is no aborted fetal tissue itself in the vaccine.

For those who are still uncomfortable with this revelation, it might be helpful to know that the Vatican has actually taken a stand on the issue. The Vatican's Pontifical Academy for Life issued a statement in 2005 saying that it is wrong to make vaccines using aborted fetal tissue and that such practices should no longer be employed, however, it is acceptable to use vaccines developed from abortions that were carried out decades ago, because immunizations play a vital role in protecting life by preventing illness and death.

In part, when referring to concerns over the production of vaccines, the academy states: "...the burden of this important battle cannot and must not fall on innocent children and on the health situation of the population - especially with regard to pregnant women."

The Catholic Church and others concerned about the use of aborted fetuses in the development of vaccinations support alternative vaccines that have been prepared using animal as opposed to human tissues and cells. In some cases such alternative vaccinations are already available. If you want to learn more about alternatives or have specific concerns, contact your pediatrician for further information.
