Maximizing OptionS to Advance Informed Choice for HIV Prevention (MOSAIC).


MOSAIC works across multiple countries to implement user-centered research and research translation efforts to identify, understand, and remove barriers to new product introduction, access, and use; coordinate and provide technical assistance to global, national, and subnational stakeholders to expedite product launch and scale-up; and strengthen the capacity of a wide range of local partners to perform essential functions that support the introduction of HIV prevention products.

Catalyzing access to new prevention products to stop HIV (CATALYST) is MOSAIC’s flagship product introduction study. The goal is to characterize and assess the implementation of an enhanced service delivery package providing choice of oral PrEP, PrEP ring, and injectable cabotegravir for PrEP among women at PEPFAR/USAID delivery sites in Kenya, Lesotho, South Africa, Uganda, and Zimbabwe. The CATALYST study will also use quality improvement methods to refine components and identify a core service delivery package for PrEP choice (refer to CATALYST study brief).
