Evaluation of the National Immunization Program in a city in the interior of Pernambuco in the light of Donabedian's triad

Vaccination coverage in Calçado is monitored, but there is a lack of structured interaction between the NIP and the teams. Epidemiological surveillance is carried out, and educational actions are promoted, but there is a lack of formal feedback from the population that can help improve services. The study provides a clear view of the NIP's performance in the municipality, allowing us to discuss the quality of the health care offered.
