Adverse Event Reporting

Adverse Event Reporting

An adverse event is any undesirable occurrence after the use of an immunobiological product, including illness or reaction, whether or not the event was caused by the product. For products intended to diagnose disease, adverse events refer to anything that hinders discovery of the correct diagnosis.

The mission of the Center for Veterinary Biologics (CVB) is to ensure that animal immunobiologics are in compliance with the Virus-Serum-Toxin Act. Reports are assessed for the possibility of a product deficiency. When necessary, testing is performed or additional information sought. The CVB is, however, unable to make diagnoses or recommendations specific to individual cases. Some of the manufacturers do provide such services. Receipt of a report by the CVB does not necessarily imply that the product caused an adverse event, or even that a particular event actually occurred.

Adverse events may be reported to the:

  • Manufacturer - The CVB encourages the public to submit adverse event reports to the manufacturer of immunobiological products. Many manufacturers maintain veterinary services departments to handle such reports and may also offer diagnostic advice, treatment recommendations and guidance on product use. Please note that reporting adverse events to the manufacturer cannot be done from this website. You will need to contact the manufacturer directly. A contact telephone number may be available on the label of the product.

  • Center for Veterinary Biologics - Once an adverse event has been reported to the manufacturer, the CVB may be contacted.
