More than 20 years after a small Duke-led clinical trial tested an experimental breast cancer vaccine, Duke Health says all participating women are still alive—an outcome researchers describe as unusual for metastatic disease. Follow-up analyses found long-lived immune cells marked by CD27, and mouse experiments suggest that stimulating CD27 can boost vaccine-driven tumor control.
Health Cabinet Secretary Aden Duale has announced plans to roll out Kenya's first locally manufactured vaccine by 2027. This milestone follows the completion of the first phase of the manufacturing facility at the Kenya BioVax Institute. The initiative supports the country's universal health coverage goals and aims to reduce dependence on imported vaccines.
