Indications
For the active immunisation of horses of 6 months of age or older against West Nile virus (WNV) disease by reducing the number of viraemic horses after infection with WNV lineage 1 or 2 strains and to reduce duration and severity of clinical signs against WNV of lineage 2 strains.
Onset of immunity: 3 weeks after primary vaccination course.
Duration of immunity: 12 months after primary vaccination course for WNV lineage 1 strains. For WNV lineage 2 strains the duration of immunity has not been established.
Dose to be administered and administration route
Administer the entire content of the syringe (1 ml), by deep intramuscular injection in the neck region, according to the following schedule:
• Primary vaccination course: first injection from 6 months of age, second injection 3–5 weeks later.
• Revaccination: a sufficient degree of protection should be achieved after an annual booster injection with a single 1 ml dose although this schedule has not been fully validated.
Adverse reactions
Horses:
Rare (1 to 10 animals / 10,0000 animals treated): |
Hypersensitivity reaction (including vomiting, incoordination, lethargy and laboured breathing)1 |
Very rare (<1 animal / 10,000 animals treated, including isolated reports) |
Hyperthermia2 Injection site swelling (sometimes associated with injection site pain and mild depression)3 |
1As with any vaccine rare, occasional hypersensitivity reactions may occur. If such a reaction occurs, appropriate treatment should be administered without delay.
2Resolves within 2 days
3Transient local reactions in the form of a mild, local swelling at the injection site post vaccination (maximum 1 cm in diameter) that resolve spontaneously within 1 to 2 days. Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system.
