Charting a Course toward a New Vaccine Strategy.

There has been a long-simmering disquiet in Catholic circles regarding the use cell lines derived from aborted fetal tissue. This concern has exploded into the public consciousness given the use of questionable cell lines in the development and/or testing of the current COVID-19 vaccines, and the debate within the Church over the permissibility of using these vaccines. The history of cell culture and how the biological community came to rely on HEK293 fetal cell lines is explored, as is the way forward, moving the biotech industry away from ethically problematic cells and toward the development of more ethically sourced cell lines. The role of the Church in leading the way forward and the acceptable use of medicines utilizing HEK293 cell lines are all explored. © Catholic Medical Association 2021.
