Regulators prepared trials in the Democratic Republic of the Congo and Uganda for Bundibugyo Ebola vaccines and therapeutics, as the outbreak continues to evolve. The plan includes testing multiple vaccine candidates and antibody and antiviral treatments. Separately, researchers highlighted how influenza coinfection can impair control of tuberculosis infection using a human challenge model, pointing to immune disruption mechanisms that could complicate co-epidemic management. The findings support more careful clinical surveillance where respiratory viral circulation overlaps with TB risk. Together, the updates show two complementary pieces of the infectious-disease playbook: outbreak-specific trial readiness and mechanistic data on how co-infections change host immunity.
