What is the VAERS website all about!

Setup in 1990, the Vaccine Adverse Event Reporting System (VAERS) is a national warning system to detect possible  problems in U.S.-licensed vaccines. VAERS is co-managed by the Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA). VAERS accepts and analyzes reports of adverse events (possible side effects) after a person has received a vaccination. Anyone can report an adverse event to VAERS. Healthcare professionals are required to report certain adverse events and vaccine manufacturers are required to report all adverse events that come to their attention. 

     VAERS is a passive reporting system, meaning it relies on individuals to send in reports of their experiences to CDC and FDA. VAERS is not designed to determine if a vaccine caused a health problem, but is especially useful for detecting unusual or unexpected patterns of adverse event reporting that might indicate safety problem with a vaccine. VAERS can provide CDC and FDA with valuable information that additional work and evaluation is necessary to further assess a possible safety concern.

 

Objectives of VAERS

The primary objectives of VAERS are to:

1:Detect new, unusual, or rare vaccine adverse events;

2: Monitor increases in known adverse events;

3: Identify potential patient risk factors for particular types of adverse events;

4: Assess the safety of newly licensed vaccines;

5: Determine and address possible reporting clusters (e.g., suspected localized [temporally or geographically] or product-/batch-/lot-specific adverse event reporting);

6:Recognize persistent safe-use problems and administration errors;

7:Provide a national safety monitoring system that extends to the entire general population
