Active substances:
Inactivated equine influenza virus, strains:
A/equi-1/Prague/5615 - 18 μg HA
A/equi-2/Suffolk/89 (European type)15 - 18 μg HA
A/equi-2/Newmarket/1/93 (American type)15 - 18 μg HA
Adjuvants:

INDICATIONS

For the active immunisation of horses and ponies to reduce clinical signs of respiratory disease and viral shedding caused by equine influenza viruses of H7N7 and H3N8 types (European and American strains) as demonstrated by serology and challenge infection using the A/equi-2/Sussex 89 and A/equi-2/South Africa/4/03 strains.
Protective antibody titres against the listed equine influenza virus strains have been shown to be present within two weeks of completion of the second dose of the primary vaccination course and protection has been demonstrated against challenge with virulent isolates of the listed equine influenza virus strains.
Following administration of the second dose of the primary vaccination course, protective antibody titres against the listed equine influenza strains last at least 6 months. After completion of the 3 dose primary vaccination course and for subsequent booster vaccinations, protective antibody titres against the listed equine influenza strains last at least 1 year.

CONTRAINDICATIONS

Do not vaccinate unhealthy horses.

ADVERSE REACTIONS

The occurrence of adverse reactions after the first and second doses is low. After the third and subsequent doses, the incidence of adverse reactions, particularly local reactions, increases.
Very commonly these reactions include visible swellings measuring less than 5 cm in diameter lasting for up to 1 day and mild, transient hyperthermia lasting up to 4 days.
Common reactions include palpable, transient swellings and visible swellings measuring more than 5 cm in diameter which resolve within weeks and stiffness of the neck evident at between 2 to 4 days after vaccination. In rare occasions, abscessation may be observed. No information on microscopic features of the injection site reactions is available.
Hypersensitivity reactions to the vaccine may occur. In the event of an allergic reaction, immediate treatment should be given with a soluble glucocorticoid intravenously (e.g. dexamethasone sodium phosphate), adrenaline intramuscularly or antihistamine intramuscularly.

TARGET SPECIES

Ponies and horses from the age of five months.

DOSAGE, ROUTE AND METHOD OF ADMINISTRATION

One 1.0 ml dose per horse to be administered by deep intramuscular injection.
Shake well before use.
Primary vaccination:
A single dose of Duvaxyn IE Plus should be administered from the age of 5 months followed by a second dose of Duvaxyn IE Plus after an interval of 4-6 weeks and a third dose 6 months later.
Primary vaccination of foals born to mares highly immunised against equine influenza (i.e. vaccinated two or more times a year or within the last trimester of pregnancy) should be delayed until the age of 6 months, as such foals may have high levels of maternally-derived antibody against equine influenza virus that could interfere with successful immunisation. In cases of increased risk of equine influenza in the young foal, especially when colostrum intake has been inadequate, an additional vaccination may be given from three months of age. Such foals should be shown to have no or very low titres of IgG using a suitable test before proceeding with early vaccination.
The full primary course of vaccination should still be given from five months of age.
Booster vaccination:
Administer a single dose of vaccine annually.
In enzootic or epizootic situations, especially where the causative strain of equine influenza has not been identified, young horses in a yard or crowded situation may be particularly at risk and an additional six month booster with Duvaxyn IE Plus may be given in order to further enhance the immune response prior to the commencement of the annual booster programme.
It is recommended that Duvaxyn IE Plus should not be used as a booster vaccine in horses previously vaccinated with another manufacturer’s vaccine nor should another manufacturer’s vaccine be used as a booster vaccine in horses previously vaccinated with Duvaxyn IE Plus unless the other manufacturer’s vaccine comprises the same equine influenza strains as Duvaxyn IE Plus.
