Citing ethical concerns about the use of stem cells in vaccine development, Bishop Joseph Brennan of the Diocese of Fresno is urging Catholics not to “jump on the COVID-19 vaccine bandwagon.”

In a video shared by the diocese this week, Brennan said the race to produce a coronavirus vaccine has spurred researchers to make use of morally objectionable materials.

“I try to maintain a joyful spirit, so I don’t like to rain on anyone’s parade,” Brennan said. “But I’m going to rain on a parade today: the vaccine parade.”

In his message, Brennan said the use of embryonic stem cells at any stage of a vaccine’s development means Catholics cannot avail themselves of its scientific results.
