Article Synopsis
- An effective TB vaccine is essential for lowering the worldwide TB burden, necessitating clinical trials in high-incidence areas.
- The authors propose a new epidemiologic method that combines different public health strategies to improve the selection of trial sites for TB vaccine testing.
- This method uses data analysis to objectively evaluate site-specific TB rates, enabling faster identification of potential trial locations that may have been overlooked, thereby minimizing bias in the selection process.
