Denver Newsroom, Nov 24, 2020 / 06:33 pm (CNA).- Amid debate over the ethics of a COVID-19 vaccine candidate under development by Moderna, a Catholic microbiologist told CNA that while research connected to aborted fetal cells may have contributed to the knowledge base being used in the vaccine’s development, the actual production of the vaccine does not use cells of any kind, fetal or otherwise.

Deacon Robert Lanciotti, a microbiologist and the former chief of the Center for Disease Control and Prevention’s diagnostic and reference laboratory in Fort Collins, Colorado, told CNA that the manner of production for the Moderna vaccine is ethically uncontroversial— in contrast to several other common vaccines, which are grown in aborted fetal cells.

Traditional vaccines use dead or altered viruses, and viruses have to be grown in cell lines, Lanciotti said. Some vaccines that are based on altered viruses are produced by growing them in aborted fetal cell lines, rendering them morally illicit for Catholics to take except for grave reasons.
