99 Percent Certainty

What really happened to Gary Davis  and his serum? Grant starts reaching out to the doctor’s family members. They are eager to tell their stories – but all have different perspectives. The daughter who spent much of her childhood in Davis’ lab, the son who was skeptical at first but then came around, the niece who tried to help Davis bring the serum to fruition in the shadow of historic racial violence. A road trip to Tulsa brings a deeper understanding of Gary Davis — and an anonymous tip leads to new insights: After the FDA shut down a clinical trial for Davis’ serum, at least one biopharmaceutical company created its own. Its trials? Approved, funded by the NIH.

Serum is a limited run podcast production of WHYY’s The Pulse and Local Trance Media.
