Should Catholics steer clear of J & J vaccine?

NEW ORLEANS (AP) — Roman Catholic leaders in St. Louis and New Orleans are advising Catholics that the COVID-19 vaccine from Johnson & Johnson, newly approved for use in the U.S., is “morally compromised” because it is produced using a cell line derived from an aborted fetus.

The New Orleans archdiocese says the decision to receive a vaccine is one of individual conscience. In its statement late last week, it stopped short of advising Catholics not to take the Johnson & Johnson vaccine, but adds that Catholics should choose coronavirus vaccines made by Moderna or Pfizer — if they are available.

The Archdiocese of St. Louis on Tuesday encouraged Catholics to seek out the Pfizer or Moderna vaccines and avoid the Johnson & Johnson version if possible. Like the New Orleans archdiocese statement, the St. Louis statement called the Johnson & Johnson vaccine “morally compromised.” However, the St. Louis statement stressed that Catholics can get that vaccine “in good conscience if no other alternative is available.”

Later Tuesday, a statement issued by chairmen of the United States Conference of Catholic Bishops’ committees on doctrine and abortion issues issued a statement reiterating the moral concerns. It said the Pfizer or Moderna vaccines are preferable “if one has the ability to choose a vaccine.”

While not disputing the church officials’ contention that an abortion-derived cell line is used in the production, Johnson & Johnson issued a statement Tuesday stressing that there is no fetal tissue in its vaccine.

Johnson & Johnson’s COVID-19 vaccine is made using a harmless cold virus, called an adenovirus, the same technology it used to produce a successful Ebola vaccine. The adenovirus is grown using what’s called an immortalized cell line, and the virus then is pulled out and purified.

Several types of cell lines created decades ago using fetal tissue exist and are widely used in medical manufacturing but the cells in them today are clones of the early cells, not the original tissue.

The United States Conference of Catholic Bishops said in a January statement that “abortion-derived” cell lines were used to test the Moderna and Pfizer vaccines but not in their development or production.
