Abstract
The use of cell lines derived from elective abortions in the development and production of COVID vaccines was opposed by the Catholic church who encouraged pharmaceutical companies and governmental health agencies to produce and distribute ethical vaccines that do not create problems of conscience for healthcare providers or those requiring vaccination. In response to the church’s call for ethical alternatives in research and development of COVID vaccines, we present an approach for the measurement of Anti–SARS-CoV-2 Ig antibodies in blood plasma (COVID-19 Antibody test) that does not utilize any products produced in aborted fetal cell lines. The SARS-CoV-2 RBD protein used in this test was produced in Chinese Hamster Ovary (CHO) cells and test performance for determination of SARS-CoV-2 seroconversion was equivalent to a commercially available COVID-19 antibody test that utilized RBD protein and other reagents produced in embryonic cell lines.
