Duration of immunity:
5 months after completion of the primary vaccination course.

12 months after the first revaccination.


Special warnings for each target species
Foals should not be vaccinated before the age of 6 months, especially when born to mares that were revaccinated in the last two months of gestation, because of possible interference by maternally derived antibodies.

Operator warnings:
In case of accidental self-injection, seek medical advice immediately and show the package leaflet or the label to the physician.

Adverse reactions
A diffuse hard or soft swelling (max. diameter 5 cm) may occur at the injection site, regressing within 2 days. In very rare cases a local reaction exceeding 5 cm and possibly persisting longer than 2 days may occur. Pain at the injection site can occur in rare cases, which may result in temporary functional discomfort (stiffness). In very rare cases, fever, sometimes accompanied by lethargy and inappetence, may occur for 1 day, and up to 3 days in exceptional circumstances.

Use during pregnancy, lactation or lay
Can be used during pregnancy and lactation.

Vaccination schedule:
Primary vaccination course
Administer one dose (1ml), by strict intramuscular injection, according to the following schedule:

•Primary vaccination course: first injection from 6 months of age, second injection 4 weeks later.

The first revaccination (third dose) is given 5 months after the primary vaccination course. This revaccination results in immunity to equine influenza lasting at least 12 months.

The second revaccination is given 12 months after the first revaccination.

The alternate use, at 12 months interval, of a suitable vaccine against equine influenza, containing the strains A/equine-2/South Africa/4/03 and A/equine-2/Newmarket-2/93, is recommended to maintain immunity levels for the influenza component (see schedule).
