Aborted fetal tissue..

[Guest guest]

> Dear Mr. And Mrs. Lambert:

>

> Thank you for your letter concerning the use of aborted fetal tissue in

> vaccines. Human cell-line cultures are used during production of some

> vaccines such as varicella, rabies, inactivated polio virus, and

> hepatitis A. Some of these cell lines originated from fetal tissue

> obtained from legal abortions in the 1960s. The term " cell-line culture "

> refers to the substrate substance that is used for the propagation of a

> live virus that is used in the production of a viral vaccine. Fetal

> tissue has not been used to produce licensed vaccines. These tissues

> were used to establish cell cultures, and it is these established cell

> cultures that have been used to propagate virus. Since cell lines can be

> maintained indefinitely, no additional aborted fetuses have been used

> since the cell lines were initiated in the 1960s.

>

> The reasons for using fetal cell lines are: (1) fetal cells divide much

> more rapidly than adult cells, and (2) there is a safety advantage in

> using human, rather than animal, cell lines for development and

> manufacture of vaccines for humans. The decision to use fetal cell lines

> was scientific and did not imply support for abortions.

>

> Vaccines have been proven over the decades to be safe and effective. I

> am glad to know that you understand the necessity of vaccines and their

> value. I hope that, before making a final decision, you will discuss

> these cncerns with your child's medical provider.
