I must've slept through that lecture. What are they talking about?
With Pfizer and Moderna’s vaccines, after they were developed and tested by the companies, the FDA requires that independent labs separate from the companies verify the testing results by running their own completely independent tests. The independent testing was performed using fetal stem cells that originated from an abortion that was performed in 1973 in the Netherlands.
Pfizer and Moderna had no control over the testing and its methods (hence - independent). And no fetal stem cells were used to develop or produce either vaccine. This was after-the-fact verification testing done by an outside entity. Other groups developing vaccines (such as Oxford) used fetal stem cells directly in their research and development of COVID-19 vaccines.
Here’s a breakdown of how ethically each vaccine was developed by the pro-life Charlotte Lozier Institute: https://s27589.pcdn.co/wp-content/uploads/2020/06/An-Ethics-Assessment-of-COVID-19-Vaccine-Programs_On-Point-46.pdf
Pfizer and Moderna are both listed under “ethically uncontroversial”.
