vaers data set

the vaers dataset is huge, contains very large dimension nominal variables, and is complex due to multiple listing of vaccines and adverse symptoms in a single report. in this article, a partial vaers dataset is considered for characterizing the cross-board patterns of the relationship between all reported vaccines and all reported adverse symptoms or events. in the parts of our analysis on the relationship between the vaccines and the adverse events or symptoms, we exclude those vectors in eq. in addition to the large size issue, the analysis of vaers data deals with nominal variables such as vaccines and events or symptoms; in particular, the symptom is a nominal variable of very large dimension. for the study of the cross-board patterns on the relationship between the vaccines and the adverse events or symptoms, we consider the top 100 adverse symptoms z1,⋯,z100 listed in table 1, and consider the vaccines v1,⋯,v71 listed in (2); that is in our analysis hereafter we exclude those vectors in processed vaers dataset (1) that list the vaccine as “unknown”.




3, is the matrix of sample correlation coefficients of top 100 adverse symptoms under all 24 different bacteria vaccines; and the square block matrix in the middle, displayed separately in fig. however, the dataset is huge, includes reports with multiple listing of vaccines and adverse symptoms in a single report, and contains reports with errors or incomplete information. 3 shows that the top 100 adverse symptoms are mostly uncorrelated or negatively correlated under different bacteria vaccines, the block matrices m16,21 and m21,16 in fig. moreover, what is discovered in this article provides a needed starting point for the development of statistical models and procedures to further analyze the vaers data. the authors are also grateful to the editor and two referees for their comments and suggestions on the earlier drafts of this article.

the information in this database contains reports received from 1990 to the present. this video demonstrates how to search vaers data using cdc wonder. reports to vaers can also be biased. the strengths of vaers are that it is national in scope and can often quickly detect an early hint or warning of a safety problem with a vaccine. vaers is one component of cdc’s and fda’s multifaceted approach to monitoring safety after vaccines are licensed or authorized for use. these systems are less impacted by the limitations of spontaneous and voluntary reporting in vaers and can better assess possible links between vaccination and adverse events.

vaers data available to the public include only the initial report data to vaers. additionally, reports to vaers that appear to be false or fabricated with the intent to mislead cdc and fda may be reviewed before they are added to the vaers database. reports to vaers can also be biased. the strengths of vaers are that it is national in scope and can often quickly detect an early hint or warning of a safety problem with a vaccine. these systems are less impacted by the limitations of spontaneous and voluntary reporting in vaers and can better assess possible links between vaccination and adverse events. additionally, reports to vaers that appear to be false or fabricated with the intent to mislead cdc and fda may be reviewed before they are added to the vaers database.

important: if you are experiencing a medical emergency, seek immediate assistance from a healthcare provider or call 9-1-1. cdc and fda do not provide vaers data is accessible by downloading raw data in comma-separated value (csv) files for import into a database, spreadsheet, or text editing program, vaccination has been one of the most successful public health interventions to date, and the u.s. fda/cdc vaccine adverse event reporting, .
