4. CLINICAL PARTICULARS
4.1 Target species
Ponies and horses from the age of five months.
4.2 Indications for use, specifying the target species
Active immunisation of horses and ponies from 5 months of age against equine influenza of H7N7 and H3N8 types (European and American strains), including the South Africa/4/03 and A/equi-2/Richmond/1/07 strains, to reduce clinical signs and virus excretion after infection.
Onset of immunity has been demonstrated by virulent challenge for equine influenza strains South Africa 4/03, Richmond 1/07 and Sussex/89, and by serology for vaccine strains Prague/56, Newmarket 1/93 and Suffolk 89.
Duration of immunity has been demonstrated by virulent challenge for equine influenza strain Sussex/89 and by serology for all other strains.
Onset of immunity: 2 weeks after administration of the 2nd dose
Duration of immunity: 6 months after administration of the 2nd dose
12 months after administration of the 3rd dose and subsequent annual booster injections.
4.3 Contraindications
Do not vaccinate unhealthy animals.
4.4 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.
In any animal population there will be a small number of individuals, which fail to respond fully to vaccination.
4.5 Special precautions for use
i. Special precautions for use in animals
Avoid stress in the animals around the time of vaccination.
ii. Special precautions to be taken by the person administering the veterinary medicinal product to animals
In the case of accidental self-injection/ingestion/spillage onto skin, seek medical advice immediately and show the package insert or label to the physician.
4.6 Adverse reactions (frequency and seriousness)
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 large, possibly painful swellings 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.
4.7 Use during pregnancy, lactation or lay
Duvaxyn IE Plus is safe for use in pregnant mares in the second to third trimester which have been vaccinated against influenza before pregnancy.
4.8 Interaction with other medicinal products and other forms of interaction
Safety and efficacy data are available which demonstrate that this vaccine can be administered on the same day but not mixed with Duvaxyn EHV 1,4 and Duvaxyn T.
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product except the products mentioned above. A decision to use this vaccine before or after any other veterinary medicinal product therefore needs to be made on a case by case basis.
4.9 Amounts to be administered and administration route
One 1.0 ml dose per horse to be administered by deep intramuscular injection.
Shake well before use.
Vaccination Schedule
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.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
Administration of a double dose does not alter the severity of the reaction seen after administration of the recommended dose (see Section 4.6).
4.11 Withdrawal period(s)
Zero days.
