Question: 

Do any of the vaccines use aborted fetuses as an ingredient? 

Answer: 
No. There are no abortions being done to make any vaccine, including the COVID-19 vaccines. Vaccines do not contain cells from aborted fetuses or other human cells. Human cell lines are used in the early stages of the production of some vaccines. Neither of the approved mRNA vaccines uses human cell lines, but the AstraZeneca and Johnson & Johnson vaccines do use these cell lines. However, for vaccines that use cell lines, all cells are removed during the purification of the vaccine.
 

Two fetuses, both obtained from abortions done by maternal choice in the 1960s, have given rise to the human cell strains used to develop some medications and vaccines. Neither abortion was performed for vaccine development. These two main human cell strains have been used to develop a small number of vaccines.
