"One of the Warp Speed candidates, made by Janssen Research & Development, uses PER.C6 cells. The second, from University of Oxford researchers and AstraZeneca, uses HEK-293 cells. Both have received U.S. government commitments of, respectively, $456 million and $1.2 billion, if they meet milestones, through the Biomedical Advanced Research Development Authority (BARDA). Another vaccine that relies on HEK-293, being developed by two companies owned by the billionaire scientist and businessman Patrick Soon-Shiong, made an earlier, Warp Speed long list of 14 promising candidates, according to a press release from one of companies, NantKwest. Prentice says: "As they are choosing—BARDA and the Warp Speed people— what vaccines to move ahead, they should at least recognize that there is some portion of the population who would like an alternative vaccine they can take in good conscience." Caplan disagrees. "If you are going to say the government shouldn't fund things that a minority of people object to, you will have a very long list of things that won't get funded by the government, from research on weapons of war to contraceptive research.""
