In a sharply worded dissent, Justice Clarence Thomas expressed support Thursday for a debunked claim that all Covid vaccines are made with cells from “aborted children.” His dissent came in a decision by the Supreme Court to not take up a legal challenge by New York health care workers who opposed the state’s vaccine mandate on religious grounds.
Thomas, citing the plaintiffs, wrote that the health care workers “object” to the state’s vaccine mandate “on religious grounds to all available COVID–19 vaccines because they were developed using cell lines derived from aborted children.”
Pfizer and Moderna used fetal cell lines early in their Covid vaccine development to test the efficacy of their formulas, as other vaccines have in the past. The fetal tissue used in these processes came from elective abortions that happened decades ago. But the cells have since replicated many times, so none of the original tissue is involved in the making of modern vaccines.
