VAERS accepts reports of adverse events and reactions that occur following vaccination. Healthcare providers, vaccine manufacturers, and the public can submit reports to the system. While very important in monitoring vaccine safety, VAERS reports alone cannot be used to determine if a vaccine caused or contributed to an adverse event or illness. The reports may contain information that is incomplete, inaccurate, coincidental, or unverifiable. In large part, reports to VAERS are voluntary, which means they are subject to biases. This creates specific limitations on how the data can be used scientifically. Data from VAERS reports should always be interpreted with these limitations in mind.
The strengths of VAERS are that it is national in scope and can quickly provide an early warning of a safety problem with a vaccine. As part of CDC and FDA’s multi-system approach to post-licensure vaccine safety monitoring, VAERS is designed to rapidly detect unusual or unexpected patterns of adverse events, also known as “safety signals.” If a safety signal is found in VAERS, further studies can be done in safety systems such as the CDC’s Vaccine Safety Datalink (VSD) or the Clinical Immunization Safety Assessment (CISA) project. These systems do not have the same scientific limitations as VAERS, and can better assess health risks and possible connections between adverse events and a vaccine.
Key considerations and limitations of VAERS data:
VAERS data available to the public include only the initial report data to VAERS. Updated data which contains data from medical records and corrections reported during follow up are used by the government for analysis. However, for numerous reasons including data consistency, these amended data are not available to the public.
Seizure; This case was received via an unknown source (no reference has been entered for a health authority or license partner) on 23-Dec-2021 and was forwarded to Moderna on 24-Dec-2021. This regulatory authority case was reported by an other health care professional and describes the occurrence of SEIZURE (Seizure) in a 16-year-old female patient who received mRNA-1273 (COVID-19 Vaccine Moderna) (batch no. 086521A) for an unknown indication. No Medical History information was reported. On 03-Dec-2021, the patient received dose of mRNA-1273 (COVID-19 Vaccine Moderna) (Intramuscular) 1 dosage form. On 03-Dec-2021, the patient experienced SEIZURE (Seizure) (seriousness criterion medically significant). At the time of the report, SEIZURE (Seizure) had resolved. The action taken with mRNA-1273 (COVID-19 Vaccine Moderna) (Intramuscular) was unknown. For mRNA-1273 (COVID-19 Vaccine Moderna) (Intramuscular), the reporter did not provide any causality assessments. No concomitant medications were reported. The treatment information was unknown; Sender's Comments: This is a regulatory case concerning a 16-year-old female patient with no medical history provided, who experienced the serious unexpected event of seizure (seriousness criterion medically significant). This event occurred on the same day the patient received the first dose of mRNA-1273 (COVID-19 Vaccine Moderna). The rechallenge was unknown since there's only information about the first dose. The benefit-risk relationship of mRNA-1273 Vaccine is not affected by this report. Event seriousness assessed as per Regulatory Authority reporting.
