Vaccination coverage in the Americas Region Vaccination coverage for the first and third doses of the diphtheria, tetanus, and pertussis vaccine (DTP1 and DTP3) are commonly used as indicators for the performance of national immunization programs, both regionally and globally, and are essential benchmarks for assessing the strength and accessibility of these programs (3). The highest concentration of cases has been reported in the Central Region (n= 515 cases), with a predominance in the province of Buenos Aires (n= 342 cases) and in the Autonomous City of Buenos Aires (n= 67 cases) (4). Cases were reported in 21 departments of the country, with the highest numbers reported in the departments of Loreto (n= 2,574 cases, including 36 deaths), Lima (n= 183 cases, including five deaths), Puno (n= 78 cases, including one death), Cajamarca (n= 47 cases, including two deaths), and Arequipa (n= 43 cases). The distribution by age group at the national level shows that 31% of cases (n= 983 cases) correspond to the 1 to 4-year age group, 28% (n= 907 cases) to the 5 to 11-year age group, and 15% (n= 482 cases) to children under one year of age.
