- Carbopol and hydroxide adjuvanted inactivated whole virus vaccine containing 'flu strains: A/equi-1/Prague/56, A/equi-2/Suffolk/89 and A/equi-2/Newmarket1/93 and tetanus toxoid.
- Stimulates humoral and cell mediated immunity.
- Where stimulation of cell mediated immunity against a whole virus vaccine, that contains conserved proteins, provides protection against strains not contained in the vaccine.
- Duvaxyn IE-T Plus has been shown in trials to cross protect against OIE recommended American-like strains - A/equi-2/SouthAfrica/4/03 and A/equi-2/Sydney07 - that caused recent equine influenza outbreaks.

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.
For the active immunisation of horses and ponies to prevent tetanus infection.
Protective antibody titres against the listed equine influenza virus strains and protective antitoxin antibody titres 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 and protective antitoxin antibody titres 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 and against tetanus last at least 2 years.
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 dose per horse to be administered by deep intramuscular injection.
Shake well before use.
Primary vaccination:
A single dose of Duvaxyn IE-T Plus should be administered from the age of 5 months followed by a second dose of
Duvaxyn IE-T 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 or tetanus
(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 and tetanus toxoid that could interfere with successful immunisation.
In cases of increased risk of equine influenza or tetanus 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, beginning with Duvaxyn IE Plus
and alternating thereafter with Duvaxyn IE-T Plus.
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-T 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-T Plus unless
the other manufacturer's vaccine comprises the same equine influenza strains as Duvaxyn IE-T Plus.
Administration of a double dose does not alter the severity of the reaction seen after administration of the recommended dose.
WITHDRAWAL PERIOD
Zero days.
SHELF LIFE
Shelf life of the veterinary product as packaged for sale: 24 months.
SPECIAL STORAGE PRECAUTIONS
Store and transport refrigerated (2°C - 8°C).

SPECIAL WARNINGS
It is recommended to vaccinate all horses on the premises according to the recommended schedule.
Maternally derived antibodies (MDA) can interfere with the development of active immunity. Please refer to section 4.9 for advice on vaccination in the presence of MDA.
Animals that have received tetanus antiserum at a therapeutic dosage should not be vaccinated until an interval of at least 4 weeks has elapsed.
Safe for use in pregnant mares in second to third trimester which have been vaccinated against both influenza and tetanus before pregnancy.
No information is available on the safety and efficacy of the concurrent use of this vaccine with
any other except Duvaxyn EHV 1,4®. It is therefore recommended that no other vaccines than
this should be administered within 14 days before or after vaccination with the product.
