SI-PNI — Aggregated Vaccine Doses (Brazil, 1994–2019)

Historical aggregated data on administered vaccine doses from Brazil's National Immunization Program (SI-PNI), covering 26 years of municipality- level records. Converted from legacy .dbf files to Apache Parquet for modern analytical access.

Part of the healthbr-data project — open redistribution of Brazilian public health data.

Structural eras

The .dbf files underwent two structural transitions over 26 years:

Era	Period	Columns	Key difference
1	1994–2003	7	Basic structure, 7-digit municipality code
2	2004–2012	12	Added dose, age group, and population fields; 7-digit municipality code
3	2013–2019	12	Same columns as era 2, but 6-digit municipality code

All eras are preserved as-is in the Parquet files. The municipality code format (7 vs 6 digits) is kept as originally recorded.

Schema

Key variables (varies by era):

Variable	Description	Available
MUNICIP	Municipality code (7 digits until 2012, 6 digits from 2013)	All eras
IMESSION	Vaccine code (per IMUNO.CNV dictionary, 85 entries)	All eras
QT_DOSE	Number of administered doses	All eras
DOSE	Dose type (1st, 2nd, booster, etc.)	Eras 2–3
FX_ETARIA	Age group	Eras 2–3
POP	Target population	Eras 2–3

For the complete vaccine code dictionary (65 unique codes across 26 years), see IMUNO.CNV from the DATASUS FTP /PNI/AUXILIARES/ directory.

Source and processing

Original source: 702 .dbf files (dBase III) from the DATASUS FTP server (ftp://ftp.datasus.gov.br/dissemin/publicos/PNI/DADOS/). Of these, 674 were successfully processed, 12 were unavailable on the server, and 16 were empty.

Processing: .dbf → R (foreign::read.dbf) → Parquet (arrow::write_dataset) → upload to R2 (rclone). No transformations are applied. Consolidated files (UF, BR, IG prefixes) were excluded — only state-level files with municipal granularity are included.

Validation: The sum of all 27 state files matches the national consolidated file (DPNIBR) with zero difference.

Known limitations

1. Government data, not ours. Values are preserved exactly as in the original .dbf files.
2. Three structural eras. Column availability and municipality code format change across time periods. Users must handle this in analysis.
3. All fields are strings. Preserves original format including municipality code leading digits.
4. No microdata. These are aggregated counts, not individual records. For individual-level data from 2020 onward, see sipni-microdados.
5. Static dataset. The Ministry stopped publishing aggregated .dbf files after 2019. The new SI-PNI system (2020+) produces individual records instead.
