No. The COVID-19 vaccines that are currently authorized in the United States do not contain any fetal cells. However, the Johnson & Johnson (Janssen) COVID-19 vaccine used a historical fetal cell line from the 1970s to produce and manufacture its vaccine. Pfizer and Moderna COVID-19 vaccine did not use a fetal cell line to produce and manufacture those vaccines. However, a fetal cell line was used in a very early phase to confirm efficacy prior to production and manufacturing.
