"Some of the COVID-19 vaccines being studied in clinical trials use cells originally isolated from fetal tissue (often referred to as fetal cells) in vaccine development or manufacturing. This research does not require fetal cells from new abortions; they use existing historic cell lines that are many decades old. Historical fetal cell lines were derived in the 1960s and 1970s from two elective abortions unrelated to vaccine development. Fetal cell lines have been used to create vaccines for diseases such as hepatitis A, rubella, and rabies. The fetal cell lines being used to produce some of the potential COVID-19 vaccines are from two sources: * HEK-293: A kidney cell line that was isolated from a terminated fetus in 1972 * PER.C6: A retinal cell line that was isolated from a terminated fetus in 1985"
