Bernice Eddy's safety tests of Cutter polio vaccine lots

Eddy, a scientist at the NIH Laboratory of Biologics Control, tested Cutter Laboratories' Salk vaccine in monkeys and found that three of six lots paralyzed them, showing live poliovirus. She reported the results to the laboratory's chief, William Workman. The results were not passed to the vaccine licensing advisory committee, which recommended Cutter for licensure on 12 April 1955. On 29 April 1955 NIH director William Sebrell chaired a meeting on the incident that produced no conclusion on what Cutter should change in its manufacturing.

Note
Secondary. Accounts disagree on the test date: Wikipedia has given 1954; other accounts place the tests in spring 1955, before licensure. Some accounts say NIH director William Sebrell also disregarded the results and that Eddy's photographs of paralyzed monkeys were not returned.
