Kenya and U.S. researchers test a new horsepox-based mpox vaccine for safety and effectiveness.

Kenya Medical Research Institute (KEMRI) and U.S. biopharmaceutical company Tonix Pharmaceuticals are conducting a Phase I clinical trial in Kenya for TNX-801, a horsepox-based vaccine designed to prevent mpox. The trial aims to evaluate the vaccine's safety, tolerability, and effectiveness. TNX-801 is considered safer and easier to administer than older smallpox vaccines, and its development follows the WHO's declaration of a Public Health Emergency due to mpox outbreaks in Africa and other regions.
