- Abstract
Background: Immunization of pregnant women seems to protect infants through passive antibody transfer, and have an impact on disease prevention in infants who have not yet started vaccination for pertussis. Objective: Analyze the behavior of hospitalization records for pertussis in children under 1 year of age according to the coverage of the Diphtheria, Tetanus and acellular Pertussis (DTaP) vaccine for pregnant women. Methods: This is an ecological, observational, quantitative study conducted with records of hospitalization due to pertussis in children under 1 year of age in southern Brazil from 2007 to 2017. Data were obtained from the hospital information system at DATASUS. Results: In the analyzed period, 342.139 children aged ≤1 year were hospitalized as a result of respiratory diseases, and 3.062 of these hospitalizations were due to pertussis. In the pre-vaccination period, the annual average was 102.2/100,000 and, in the post-vaccination period, it was 46.8/100.000, representing a 54.2% decrease in the number of records, varying from 27.8/100.000/year in 2007 to 139.0/100.000/year in 2013, and reducing to 47.9/100.000/year in 2017. Conclusion: There was a reduction in the number of hospitalizations due to pertussis after the introduction of the DTaP vaccine, even with vaccination coverage <50%.
