In partnership with the NCD Alliance and the World Heart Federation, we are pleased to introduce this educational course on, "Vaccine-Preventable Diseases." This course explores how vaccines address the intersection of communicable and non-communicable diseases (NCDs) to support global health goals. It begins with an overview of overlapping disease burdens, focusing on impacts to vulnerable populations and strategies aligned with Sustainable Development Goals (SDGs). Key topics include influenza and COVID-19 immunization, with insights into vaccine mechanisms, infection rate reduction, and cardiovascular risk mitigation.
