"Did Regeneron use aborted fetal cells to make the monoclonal antibodies that Trump received?
"No. Although the monoclonal antibodies infused into Trump were not made from or in fetal cells,
Regeneron did develop that treatment with the help of a long-lived line of cells established from the kidneys of a fetus electively aborted in the Netherlands around 1972. The company relied on those widely used cells, known as HEK-293 cells, to make mimics of the coronavirus spike protein. Researchers used these proteins to test the potency of antibodies found in COVID-19 patients or made in mice with a humanlike immune system (see initial question). The antibodies selected for the company’s cocktail, however, were then mass produced in nonfetal cells. The creation of the humanized mice also did not rely on HEK-293 cells or other cells from aborted fetuses or human embryos. Regeneron scientists detail their methods in the supplementary material to this paper published in Science in August."
