Phase-two trials of Kenya's HIV/AIDS vaccine are underway, local newspaper the East African Standard reported on Thursday.
Phase-one safety trials in the Kenya AIDS Vaccine Initiative (KAVI) were started two years ago.
KAVI's lead researcher, Prof Job Bwayo, said while the initial phase was tested in two groups of 18 volunteers each, the second phase would involve between 100 and 1,000 volunteers.
Bwayo said with the success of the initial phase, he was hopeful that phase-three trials - the results stage - would begin sooner than expected.
