Abstract

Objective: To analyze the correlation between pentavalent vaccine coverage and the incidence of pertussis in children under 1 year of age in Jacareí-SP between 2012 and 2025, with emphasis on implications for Primary Health Care (PHC). Methods: Descriptive, retrospective study based on secondary data from SINAN and DATASUS. Confirmed pertussis cases and the vaccination status of children under one year were analyzed, along with annual vaccination coverage rates. Results: Between 2012 and 2025, 31 cases were confirmed, 64.5% in children under 1 year. Of these, 95% had incomplete or no vaccination schedules. Pentavalent vaccine coverage fell short of the 95% target in several years. Conclusion: An association was observed between low vaccination coverage and higher incidence of pertussis in infants. This scenario highlights challenges for PHC in terms of epidemiological surveillance, adherence to the vaccination schedule, and strengthening preventive actions in communities.
