In datasus: An Interface to Brazilian Public Health Data

Read anonymous ESAVI notifications

Description

Downloads anonymous individual records from the e-SUS Notifica ESAVI module. The source contains notifications since January 2021 and is continuously updated. An event following immunization does not by itself establish a causal association with a vaccine.

esavi(
  formato = "CSV",
  destino = NULL,
  cache = TRUE,
  atualizar = FALSE,
  n_max = Inf,
  colunas = NULL,
  normalizar = FALSE,
  ...
)

Arguments

formato	File format, '"CSV"' or '"JSON"'.
destino	Optional destination file or existing directory.
cache	Whether to reuse the local OpenDataSUS cache.
atualizar	Whether to force a fresh metadata query and download.
n_max	Maximum number of rows to read.
colunas	Optional character vector selecting columns during CSV parsing.
normalizar	Whether to apply the curated contemporary schema with [datasus_padronizar()].
...	Additional arguments passed to the underlying reader.

Value

The parsed OpenDataSUS resource with provenance metadata.
