"The United States bishops' conference has said that Catholics can take two of the three available COVID-19 vaccines, even though they were developed with a "remote connection" to "morally compromised" cell lines. In a statement released Monday, the bishops also said it is morally permissible in some circumstances to receive a third vaccine, developed in close connection with aborted cell lines, but that Catholics cannot allow the pandemic to "desensitize" or "weaken our determination" to oppose the evil of abortion."
