The approval of the Johnson & Johnson COVID-19 vaccine for use in Canada has heightened the discussion over whether Catholics should receive the vaccine, though Church teaching remains clear that it is “morally acceptable.”

The Johnson & Johnson vaccine is produced using cell lines derived from aborted fetuses, unlike the Pfizer and Moderna vaccines, which are made using a synthetic messenger RNA. However, all the companies used abortion-derived cells during preliminary laboratory testing.

In a December statement, the Vatican’s Congregation for the Doctrine of the Faith, while not endorsing the use of abortion-related cell lines, deemed the vaccines acceptable when “ethically irreproachable” vaccines are not available.

“People should be aiming to get the (vaccines) that don’t have (aborted fetus) components,” said Moira McQueen, executive director of the Canadian Catholic Bioethics Institute. “But if they were not available – and in some countries they may not be because their government isn’t purchasing those ones – then the Church is still saying, use them because you’re facing a lethal illness or death. You’re remote from the original source. So remote that you’re not co-operating in evil.”

Cell lines used in the Johnson & Johnson vaccine are drawn from tissue obtained from two abortions that occurred in the last few decades. Cells of this kind are easily and frequently reproduced in labs and therefore to some are considered far removed from the original source.

Health professionals and many in the Catholic faith community encourage people to get the first vaccine available to them since the moral responsibility of helping to achieve herd immunity from this deadly disease as soon as possible outweighs any ethical concerns.

The U.S. Conference of Catholic Bishops’ issued a statement on the Johnson & Johnson vaccine saying that although taking these vaccines may be permitted, Catholics should continue in efforts to push pharmaceutical companies to look more ethically at the matter.

“While we should continue to insist that pharmaceutical companies stop using abortion-derived cell lines, given the world-wide suffering that this pandemic is causing, we affirm again that being vaccinated can be an act of charity that serves the common good,” said their March 2 statement.

Bishops in western Canada made a similar statement in December, reiterating that the “for the good of personal and public heath,” receiving these vaccines is permissible because of the “urgent need” to halt the pandemic.

Joseph Zalot, a staff ethicist at the U.S. National Catholic Bioethics Center, told Catholic News Agency that while Catholics are free to choose to wait for a more ethical vaccine – or even to not receive a vaccine at all – they must take into account the potential effects not only on their own health, but on the health of others.

Zalot commented that he hopes most Catholic hospitals will have tried, as much as possible, to order the Pfizer or Moderna vaccines rather than the Johnson & Johnson. 

“However, if the J&J vaccine has already arrived, the question then becomes, ‘Which is the greater evil – issuing these vaccines knowing their ‘heightened’ connection with abortion-derived cell lines or letting them go to waste when people could greatly benefit from them?’” Zalot said. 

“As much as I personally would seek to avoid accepting the J&J vaccine, I also don’t think it would be prudent to let them go to waste.”

Controversy over the use of cells from aborted fetuses in vaccine development and laboratory testing is nothing new. Other common vaccines have been subject to the same moral debate over the years.

“They’ve been so much in use over the decades and people didn’t know,” said McQueen. “If we start to look very closely at a lot of common pharmaceuticals, we’ll find that they were maybe at least tested with agents that contain some of (those cells). Apparently they give good test results just on a scientific level.”

Some Catholics have a problem with vaccines of any kind with association to these cells. Though this makes the situation difficult, McQueen says, the confirmation from the Vatican that Pope Francis and Pope Benedict received the Pfizer vaccine in mid-January paints a very clear picture in terms of what is accepted.
