Several Used Abortion-Derived Cell Lines in Testing; Experts Urge All Vaccine Developers to Use Noncontroversial Alternatives

Washington, D.C.  – Today, Charlotte Lozier Institute (CLI) published a new chart detailing whether the eight leading COVID-19 vaccine candidates supported by Operation Warp Speed are produced or tested using cells derived from abortions. The vaccine candidates evaluated are those produced by Pfizer/BioNTech, Moderna, AstraZeneca, Johnson & Johnson, Novavax, Sanofi/GSK, Inovio, and Merck.

CLI’s analysis found that most vaccine candidates did not use abortion-derived cell lines in their production. Several used abortion-derived cell lines in laboratory testing, or their use in testing could not be determined. 

CLI offered the following additional statement:

“CLI’s expert scientific analysis finds that many leading vaccine candidates supported by Operation Warp Speed do not use abortion-derived cell lines in their production. This is encouraging news.

“Unfortunately, some vaccine developers have unnecessarily put American families in a difficult position by choosing to use controversial human fetal cell lines in production or testing, or by a lack of transparency. Many developers already opt to use animal cell lines, non-fetal human cells, yeast, or chicken eggs instead. We urge all developers to avail themselves of these options going forward. Doing so will reduce vaccine hesitancy for those who oppose the use of fetal cell lines, thereby increasing the public health impact of the vaccine.

“It remains to be seen which vaccines will be approved for emergency use and how soon they will be available to patients. CLI will continue to provide the public with access to timely and accurate information so that individuals and families can weigh all factors – including secular science and religious traditions – and make vaccine decisions in line with their conscience.”
