ABSTRACT

Introduction: With the introduction of covid-19 vaccines into Immunization Programs, the

reporting of events supposedly attributable to vaccination or immunization (ESAVI) has

become crucial for pharmacovigilance of adverse events. The ESAVI reporting rate is a

performance indicator to assess the progress of passive ESAVI surveillance, adapted to the

specificities of each locality. Objective: To analyze the spatial distribution of ESAVI

notifications resulting from the Covid-19 vaccine in the state of Minas Gerais. Methods:

Initially, ESAVI notification rates were calculated for all municipalities and then for health

macroregions. Spatial scan statistics and geographically weighted regression (GWR) were

performed to identify spatial clusters, compliance with ESAVI surveillance goals, and factors

associated with the spatial distribution of ESAVI notification rates. Results: In Minas Gerais,

clusters with low notification rates or even no notifications regarding ESAVI surveillance for

covid-19 vaccines were observed. Additionally, it was noted that despite all health

macroregions meeting the notification rate goal, 20.3% (n=173) of their municipalities did not

reach this goal. Two major clusters with low notification rates, identified as cold spots, were

highlighted in the Northern macroregion. Clusters with high notification rates, considered hot

spots, included the Northwest, Central, and Northern Triangle macroregions. Two factors were

associated with notification rates: the number of nursing professionals per inhabitant and the

percentage of families residing in rural areas. The distribution of these variables associated with

the ESAVI notification rate appeared heterogeneous throughout the state. Conclusion: The

analysis of the spatial distribution of ESAVI notifications in the state identified silent regions

that did not meet the minimum ESAVI notification value. The presence of clusters with low

notifications indicates the need to implement integrated strategies adapted to the specificities

of each health macroregion to enhance ESAVI surveillance in Minas Gerais. Investments in a

sufficient and qualified nursing professional capacity per inhabitant are essential to increase

ESAVI reporting and, moreover, to implement greater surveillance of these events in families

residing in rural áreas.
