The U.S. Centers for Disease Control and Prevention (U.S. CDC) provides technical and funding support for NITAG capacity building and evidence-to-recommendation (EtR) process. This includes the development of EtR trainings, assessment tools, and tailored guidance to enhance NITAG functionality. Additionally, U.S. CDC engages in collaborative efforts with global and regional partners to foster network development and knowledge exchange. We also facilitate ongoing support and evaluation to ensure the effective implementation of best practices and continuous improvement in immunization-related evidence-based decision-making.
