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.
dead; Collapsed; bnt162b2 was given to patient with immunocompromised w/ reportable conditions; bnt162b2 was given to patient with immunocompromised w/ reportable conditions; This is a spontaneous report from a contactable nurse. A 40-year-old male patient receive first dose of bnt162b2 (Lot number: EK9231, Brand: Pfizer), intramuscular in left arm on 21Jan2021 15:15 at single dose for COVID-19 immunization. Medical history included immunocompromised w/ reportable conditions from an unknown date and unknown if ongoing, positive for Covid in September from Sep2020 to an unknown date. The patient's concomitant medications were not reported. The patient experienced dead, collapsed on 26Jan2021. Therapeutic measures were taken as a result of collapsed. The outcome of collapsed was unknown. The patient died on 26Jan2021. It was not reported if an autopsy was performed. Received Covid vaccine here on 21Jan2021, was at work on 26Jan2021 and collapsed, no known complaints at the time, CPR (cardiopulmonary resuscitation) was initiated immediately, transported to ER (Emergency room) and pronounced dead. Unknown if other vaccine in four weeks. The patient had COVID prior vaccination. Unknown If COVID tested post vaccination.; Sender's Comments: Based on the information currently provided, the patient was immunocompromised and had prior COVID infection. The death and syncope more likely are associated with the patient underlying medical conditions. More information such medical history, concomitant medications, treatment indication and event term details especially death cause and autopsy results are needed for fully medical assessment. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees and Investigators, as appropriate.; Reported Cause(s) of Death: Dead
