There were no cell lines used in the manufacture of the pfizer vaccine itself...but I did learn they may have used certain cell lines to check reactivity to the vaccine itself. Not sure why they couldn’t have used less controversial cell lines.
It was the rush to commercial market and ensuing profits.
Other pharmaceutical companies are working on ethical, untainted vaccines, but I fear they may never reach commercial distribution.

Dr, Alan Moy of the John Paul II Medical Research Institute states that developing a safe, ethical and effective vaccine for COVID 19 is more problematic using cells derived from aborted children than non-human abortion sources:
The donated human tissue must be reproducible and of high quality. These requirements cannot be achieved from abortions. Medical records from abortions are scarce, inadequate and incomplete.…There are over 1 million annual newborn deliveries. Accurate medical records can be obtained. The tissue is reproducible.…where new cell lines can be produced in a matter of few weeks .…Newborn stem cells are rarely contaminated with pathogens. Medical records are accurate and tissue is always obtained with proper informed consent. Thus…to create human cell lines from abortion…is a poor choice. [47]
Pro-life Catholic and Christian religious leaders as well as spokesmen for pro-life medical, legal and advocacy organizations wrote to FDA Commissioner Dr. Stephen Hahn on April 17, 2020 strongly urging him to not lend government assistance to the development of a COVID 19 vaccine that is in any way linked to using tissue from aborted children.

Thankfully, President Trump has been very responsive to Pro-life requests. In 2019, his Administration suspended federal funding of previously approved HHS research contracts which used tissue derived from elective abortions despite opposition of a prominent fetal research scientist, who complained that, “Anything we do at this point could save hundreds of thousands of lives. If you wait, it’s too late.” [49]
