In Latin America, almost 2.7 million infants younger than 1 year of age, have incomplete vaccination schedules, and vaccine preventable diseases such as measles or polio have increase worldwide. ZDC are reported to reside in high risk and fragile settings, including remote-rural areas, urban slums, and conflict-affected areas. Identifying the problem and settings in each country is mandatory to propose possible solutions to the immunization coverage situation.enCC BY-NC-ND 4.0DOSE-ZERO CHILDRENVACCINATIONINMUNIZATIONNATIONAL IMUNIZATION TECHNICAL ADVISORY GROUPSNITAG´sDOSIS CERO DEL NIÑOINMUNIZACIÓNVACUNACIÓNGRUPO NACIONAL DE ASESORAMIENTO TÉCNICO SOBRE VACUNACIÓNArtículohttps://orcid.org/0000-0001-5108-2534
