The Jezierski papers: live polio vaccine development in colobus monkey cells but not chimpanzee cells in the Belgian Congo, 1952-1958

A reading of ten relevant papers by Alexandre Jezierski provides evidence f or the only attempt in Central Africa to develop a live oral polio vaccine (OPV) from growing reference wild polio strains to 210 passages in colobus monkey tissue culture, and experimental administration to about 25 humans. Chimpanzees were used as a human model, but their tissues or kidneys were a bsent from the passage and production line of the proposed vaccine. Thus, t he implication published by Hooper that Jezierski had produced a candidate OPV that might have contained chimpanzee viruses, possibly simian immunodef iciency virus cpz or the precursor of human immunodeficiency virus-1 group M, is incorrect.
