ABSTRACT
Objective:
To analyze immunization errors in pregnant women from Minas Gerais, according to the absence and presence of Adverse Events Following Immunization.
Methods:
This is a cross-sectional study, carried out with data on immunization errors in pregnant women, between 2015 and 2019, registered in the Information System for the Surveillance of Adverse Events, in Minas Gerais. The trend of the incidence rate of immunization error per 100,000 doses applied was checked using Prais-Winsten models.
Results:
Of all notifications, 3.72% were vaccination errors with adverse events following immunization. The highest proportion of immunization errors with no adverse events (32.40%) was in the macro-region Centro and, with adverse events (27.78%), in Triângulo do Sul, both with a stationary trend in the period. Regarding the incidence rate, the macro-region with the highest immunization errors with no adverse events was Vale do Aço and the macro-region with the highest incidence rate of immunization errors with adverse events was Triângulo do Sul.
Conclusion:
In this study, the notifications of Adverse Events Following Immunization resulting from vaccination errors with and without adverse events occurred with no significant trend within the years of the study.
