Adverse Events Industry Guidance

Last Modified: April 24, 2025

The Virus-Serum-Toxin Act regulations concerning records and reports, as specified in 9 CFR 116.9, require veterinary biologics licensees and permittees to record and submit reports concerning adverse events associated with the use of the veterinary biological products they produce and distribute. 

These records and reports will assist VS in monitoring the performance of licensed veterinary biological products over time, while also allowing VS to provide complete and accurate information to consumers regarding adverse events or other possible concerns associated with the use of these products.
