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.
I am the epidemiologist for reporting on behalf of patient who tested positive for COVID-19 via PCR on 4/14/21 after the completion of a full Pfizer vaccine series (Dose 1 on 2/28 and Dose 2 on 3/21). The patient later died on 5/08/21. Cause of Death is listed as ?cardiopulmonary arrest; Anoxic encephalopathy; V. Fib cardiac arrest; Myocardial infaction?. Pre-existing conditions listed as: OTHER CHRONIC DISEASES, CARDIOVASCULAR DISEASE, IMMUNOCOMPROMISED CONDITION Case went to Hospital ER on 4/14 after experiencing chest pains for 2-3 days. Rapid COVID test on 4/14 was negative & PCR test on 4/14 was positive. Case remained in ER for retesting on 4/15 (PCR - negative) so she could be admitted to hospital for cardiac catheterization. Case reports having a mild fever at hospital on evening of 4/15 & morning of 4/16. Hospital Internist DX was mild case of COVID with elevated enzymes that indicated a cardiac event. Case is fully vaccinated (1st dose of Pfizer 2/28 & 2nd dose of Pfizer 3/21). Case has history of lupus & rheumatoid arthritis (immuno-suppressed). She receives PT 2-3x/week & biologic treatment (last infusion of Orencia was 4/13). Advised case to follow-up with her PCP & cardiac specialist. Case agreed to isolation guidelines. Case lives alone but has 2 adult sons who live nearby that will provide food drop-offs at door. Emailing vaccination breakthrough info to Epidemiologist & supervisors.nnn=======================nnApril 15, 2021 at 3:28 PM ET Left SMS/VM.
