Malaria experiments
Rose's predecessor as Head of Department at the Robert Koch Institute was Claus Schilling. Schilling had performed malaria experiments; Rose continued his experiments, mostly with psychiatric patients. In 1917, the Austrian psychiatrist Julius Wagner-Jauregg used malaria infection as a treatment for General paresis of the insane. Rose used the same treatment for schizophrenia. 
Rose carried out his malaria experiments on the mentally ill at Dachau concentration camp, Buchenwald concentration camp, and with Russian prisoners in a psychiatric clinic in Thuringia.Between 1941 and 1942, Rose tested new antimalarial drugs for IG Farben in Arnsdorf. The Arnsdorf sanatorium documented the malaria experiments which Rose performed. By July 1942, 110 patients had been infected by mosquito bites. In the first test series, which had 49 human subjects, four people died. The experiments in Arnsdorf coincided with the Aktion T4, the Nazi government's mass murder campaign against the disabled and mentally ill. Psychiatric patients in Arnsdorf were transferred to other institutions and killed there. According to the company, Rose sought out one of the main organizers of Aktion T4, Viktor Brack, and was promised that his subjects would not be transferred.From January 1942 onward, Rose conducted human experiments in Dachau concentration camp to develop a vaccine against malaria.
