The U.S. Conference of Catholic Bishops (USCCB) released a statement on March 2 encouraging Catholics to avoid getting the latest adenovirus vector COVID-19 vaccine from Johnson & Johnson if alternatives are available.
In Thursday’s statement, Bishop Kevin Rhoades, chairman of the conference’s Committee on Doctrine, and Archbishop Joseph F. Naumann, chairman of the conference’s Committee on Pro-Life Activities, recommended Catholics get the mRNA vaccines from Pfizer or Moderna over Johnson & Johnson, if possible, because the latter adenovirus vector vaccine was developed with the help of abortion-derived cell lines.
