Updated March 3, 2021

Accurate information about the development and production of COVID-19 vaccines is essential, especially because many proposed candidates use newer molecular technologies for production of a viral vaccine. One concern regarding the ethical assessment of viral vaccine candidates is the potential use of abortion-derived cell lines in the development, production or testing of a vaccine. This analysis utilizes data from the primary scientific literature when available, along with data from clinical trial documents, reputable vaccine tracking websites, and published commercial information.1 It is the hope that by providing accurate data, recipients can make well-informed decisions regarding vaccine choices.

Flow Chart for Creation and Testing of Vaccines

Design & Development: conceptualization, preparatory experiments, and specification for how vaccine will be constructed and produced.


Production: process used to manufacture final vaccine to be given to people.


Confirmatory Lab Tests on Product: tests to analyze quality, nucleic acid or protein sequence, protein conformation, antibody reactivity, etc. of final vaccine product.


Vaccination: giving final produced vaccine to people.
