The World Health Organization has initiated a pilot coordinated scientific advice (CSA) procedure whereby product developers may obtain WHO advice on the most appropriate way to generate evidence on a product's benefits and risks. “WHO has been interacting with health product developers for many years but there wasn't a standardized or formalized approach to do it. We're quite well-positioned to be a coordinated and single entry point to initiate that dialogue,” explains WHO Science Division Unit Head Anna Laura Ross. “We have additional considerations around the needs of lower- and lower-middle-income countries or settings with limited resources,” says Science Division Technical Officer Mercedes Perez Gonzalez. “For example, the need for inclusion of specific populations, where you would find certain concomitant infections not necessarily present in higher income settings.”
