Obel, the Chief Research Officer published in two medical journals the initial results of the new found drug "Kemron" that was perceived from the preliminary study of 10 patients to cure AIDS. The drug was introduced in a public ceremony presided by Kenya's former President, Daniel Toroitch Arap Moi and the work of the new wonder drug discovered was hailed as a major step against AIDS and a win for African Science by the former Vice President and Finance Minister George Saitoti.
