The study will operate at three Canadian sites and enroll about 80 healthy adults. Researchers will assess the vaccine’s safety, tolerability and ability to produce an immune response. The trial will not determine whether the vaccine prevents infection because Phase 1 studies focus on early safety data. The Coalition for Epidemic Preparedness Innovations has committed up to $50 million for preclinical work, the trial and production of additional research doses. WHO recorded 3,605 confirmed cases and 1,587 deaths in DR Congo through July 30. At least 651 patients had recovered by that date. Updated figures cited by CEPI on August 4 placed infections above 3,800 and deaths above 1,700. Cases had reached 49 health zones across Ituri, North Kivu, South Kivu, Haut-Uélé and Tshopo provinces. Thirty-three health zones had reported recent infections, while Ituri accounted for 88% of confirmed cases.
