Janssen and its global partners say they are ending the Phase 3 Mosaico HIV vaccine trial following an independent, scheduled data review that found the regimen was not effective in preventing HIV infection compared to a placebo among study participants. A Janssen [statement](mailto:https://www.jnj.com/janssen-and-global-partners-to-discontinue-phase-3-mosaico-hiv-vaccine-clinical-trial) says no safety issues with the vaccine regimen were identified.
