The World Health Organization has recently released the refugee and migrant health toolkit, a one-stop resource for countries to advance the health and migration agenda. The toolkit includes essential knowledge concerning refugees’ and migrants’ health, addressing definitions, global trends, global legal frameworks and protocols. It is made up of 6 modules. The first one, “Short- and long-term public health interventions to promote refugee and migrant health” includes a chapter regarding immunization, which contains guidelines, documents for technical guidance, frameworks, training sources and tools. This toolkit will be a precious resource for member states and nongovernment actors to consult.
