The Health Intervention and Technology Assessment Program (HITAP) has been working with the Access and Delivery Partnership (ADP), hosted by the United Nations Development Programme (UNDP), to support countries to strengthen their capacity to strengthen evidence-informed decisions for health. HITAP has developed numerous partnerships with countries and academic institutions to provide internship opportunities, training workshops, technical advice to build capacity for Health Technology Assessment (HTA). These engagements aim to raise awareness on the need for HTA to realise an efficient health system and, subsequently, build the knowledge and technical capacity of such institutions to conduct HTA studies. This purpose of this report is to provide an overview of the virtual vaccinology course held in December 2021, starting from the inception and the objectives, to optimising the proceedings of the course, feedback received, lessons learned and outcomes.
