About
This collection focuses on reported adverse events following vaccination, providing essential details for public health monitoring and research. The records document various administrative and clinical factors associated with vaccine reports, including specific product identifiers, manufacturing details, and the type of vaccine administered. The information is crucial for understanding post-vaccination surveillance and trends, with a high concentration of records related to COVID-19 vaccinations. The data enables detailed analysis of vaccine types such as PFIZER\BIONTECH and MODERNA products.
Columns
- VAERS_ID: A unique identifier assigned to each adverse event report.
- VAX_TYPE: Specifies the general classification of the vaccine administered, frequently showing COVID19 as the primary type.
- VAX_MANU: Identifies the manufacturer of the vaccine product.
- VAX_LOT: Provides specific lot numbers associated with the reported vaccine batch. This column contains a significant number of missing or unknown values.
- VAX_DOSE_SERIES: Indicates the dose number in the vaccination series (e.g., Dose 1).
- VAX_ROUTE: Describes the method of administration (e.g., Intramuscular (IM)).
- VAX_SITE: Specifies the anatomical site where the vaccine was administered, often recording the Left Arm (LA).
- VAX_NAME: Presents the specific, detailed product name of the vaccine administered, such as COVID19 (PFIZER-BIONTECH).
Distribution
The dataset is typically distributed in CSV format, often made available for download as compressed ZIP files, where each compressed file contains three individual CSV files. The core data file,
vars.csv, is approximately 21.46 MB in size and contains 8 columns. Key fields generally show around 284,000 valid records. The data is structured with detailed statistical distributions provided for identifiers and categorical fields, showing varying levels of data completeness across columns like VAX_LOT, VAX_ROUTE, and VAX_SITE. Updates to this dataset are expected to occur annually.Usage
This data is ideal for applications involving clinical surveillance and epidemiological studies related to vaccine safety. Specific use cases include data visualization of adverse event trends, statistical classification of report characteristics, and detailed data analysis to inform public health policy. Researchers can use this information for data cleaning exercises and analysis focusing on specific manufacturer or vaccine type performance.
Coverage
The data originates from a US government surveillance system, implying a focus on reports submitted within the United States regulatory framework. While specific temporal coverage details are provided by selectable time intervals during download, the exact range is not fixed here. The scope heavily covers COVID-19 vaccines and associated demographics based on reporting patterns, with the majority of reported events concerning products from PFIZER\BIONTECH and MODERNA.
