Adverse events and reporting
Any adverse events that a horse experiences after receiving an influenza vaccination should be reported to the vaccine manufacturer, even if the vaccine has been used off label. This is one of the major ways the manufacturers monitor both the safety and efficacy of their products.
The Veterinary Medicines Directorate (VMD) also monitors the safety and efficacy of veterinary products in the UK.
Adverse events include:
1. Suspected failure to protect – i.e. a horse that develops signs of influenza when a product is used according to the label.
2. Any reactions, clinical signs or illness that follows injection either on or off label
Adverse reactions can be reported directly to the vaccine manufacturers or to the VMD by filling out the form below. If a horse has received more than one type of vaccine then it is the manufacturer of the last vaccine given that should be reported to.
Contact details for reporting adverse reactions:
Adverse events should be reported on a Yellow Form, which can be found on the VMD website https://www.vmd.defra.gov.uk/adversereactionreporting or downloaded below.
