In September 2019, IFPMA and the Health Policy Partnership published a new report on a life-course approach to immunization. Launched along the sidelines of the European Commission and World Health Organization Global Vaccination Summit, the report offers a policy framework for countries to maximize individual and population-wide health and economic benefits of a life-course approach to immunization. It draws on research from six countries – Australia, Japan, France, Brazil, the United Kingdom, and the United States of America – and their experience in controlling vaccine-preventable diseases by implementing a life-course approach to immunization. Taking a life-course approach can improve health, support health system sustainability, and promote economic prosperity.
