About
Drawing upon open-source information from the VAERS website, this product compiles voluntary reports related solely to adverse reactions following COVID-19 vaccinations. The data spans reports filed between December 2020 and November 2021. It is important to note that all reports are voluntary submissions from individuals who believe they experienced an adverse reaction, and therefore, the data cannot establish a causal link between the vaccine and the reported reaction, nor can the veracity or completeness of all data points be confirmed. The dataset includes rich details about the reporter, the symptoms experienced, and specifics of the vaccine administered. It is provided in the context of approximately 453,000,000 COVID-19 vaccine doses having been administered up to the time of publication.

The data consists of 42 columns providing granular detail on the reports:
VAERS_ID: A unique identification number for each report.RECVDATE: The date the vaccine was received.STATE: The location (State) where the vaccination occurred.AGE_YRS: The age of the recipient in years (Mean is 49.8 years).CAGE_YR: The calculated age of the recipient in years (Mean is 49.5 years).SEX: The reported sex of the recipient (68% Female, 29% Male).RPT_DATE: The date the adverse event report was completed.SYMPTOM_TEXT: A free-text description detailing the symptoms reported.DIED: A boolean field indicating if the recipient died (approx. 1% of valid records).DATEDIED: The recorded date of death, if applicable.L_THREAT: A boolean field indicating if the event was considered life-threatening (approx. 2% of valid records).HOSPITAL: A boolean field indicating if the recipient was hospitalised (approx. 7% of valid records).HOSPDAYS: The number of days the recipient spent in the hospital (Mean is 15.2 days).DISABLE: A boolean field indicating if the event resulted in a disability (approx. 2% of valid records).RECOVD: The status of recovery (36% No, 32% Yes).VAX_DATE: The date the vaccine was administered.ONSET_DATE: The date the adverse event symptoms began.NUMDAYS: The calculated number of days between the vaccination date and the onset date (Mean is 28.6 days).LAB_DATA: Information regarding diagnostic data.V_ADMINBY: The type of facility that administered the vaccine.OTHER_MEDS: Details of other medications the recipient was taking.CUR_ILL: Any illness the recipient had at the time of vaccination.HISTORY: Details of any chronic health issues.PRIOR_VAX: Details of prior adverse reactions to other vaccines.OFC_VISIT: A boolean indicator for an office visit (20% True).ER_ED_VISIT: A boolean indicator for an emergency room or urgent care visit (13% True).VAX_TYPE: The type of vaccine (100% COVID19).VAX_MANU: The manufacturer of the vaccine (MODERNA 46%, PFIZER\BIONTECH 45%).VAX_DOSE_SERIES: The number of doses administered (52% were Dose 1).
Distribution
The data product is available in CSV format, with a file size of 624.55 MB. It contains 42 data fields. While the total number of records (VAERS IDs) is extensive, several fields relating to medical history and diagnostic details exhibit significant percentages of missing data; for example, the
LAB_DATA field is 60% missing, and the PRIOR_VAX field is 95% missing.Usage
The data is publicly available for study and utilisation. It is suitable for monitoring reported adverse events following COVID-19 vaccination. Researchers can analyse reporting trends over time, correlate reported symptom onset with vaccination dates, and observe the distribution of reports across various demographic groups, such as age and sex. Analysts may also leverage the structured fields to investigate the frequency of serious outcomes, including hospitalisation, disability, and death.
Coverage
The dataset captures COVID-19 vaccine adverse event reports filed during the period spanning December 2020 through November 2021. Geographically, information on the State of vaccination is provided, though 12% of reports lack this detail; California represents the most reported location at 10%. Demographically, the mean age of recipients is approximately 50 years. Female recipients account for 68% of the reports, while males account for 29%.
