Target Species
Pigs
Indication for use, specifying the target species
Active immunisation of pigs from the age of 56 days onwards including pregnant sows against swine influenza caused by subtypes H1N1, H3N2 and H1N2 to reduce clinical signs and viral lung load after infection.
Onset of immunity: 7 days after primary vaccination
Duration of immunity: 4 months in pigs vaccinated between the age of 56 and 96 days and 6 months in pigs vaccinated for the first time at 96 days and above.
Active immunisation of pregnant sows after finished primary immunisation by administration of a single dose 14 days prior to farrowing to develop high colostral immunity which provides clinical protection of piglets for at least 33 days after birth.
Contraindications
None.
Special warnings for each target species
None.
Special precautions for use
Special precautions for use in animals
Not applicable.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
In case of accidental self-injection only a minor injection site reaction is expected.
Adverse reactions (frequency and seriousness)
A transient slight swelling may occur on very rare occasions after vaccination at the site of injection, regressing within 2 days. On very rare occasions, a slight transient rectal temperature increase might occur after vaccination.
Use during pregnancy, lactation or lay
Can be used during pregnancy and lactation.
Interaction with other medicinal products and other forms of interaction
No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product. 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.
Amounts to be administered and administration route
For intramuscular use.
Piglets:
Primary vaccination: 2 injections of one dose (2 ml)
- From the age of 96 days, with an interval of 3 weeks between injections to achieve duration of immunity over 6 months.
or
- Between the age of 56 and 96 days, with an interval of 3 weeks between injections to achieve duration of immunity over 4 months.
Gilts and sows:
Primary vaccination: see above
A booster is possible at each stage of pregnancy and lactation. When vaccination is performed 14 days prior to farrowing with one dose (2 ml), it provides maternally-derived immunity to the piglets which protects them from clinical signs of influenza at least until day 33 after birth.
Maternally-derived immunity in the piglets interacts with antibody induction. Generally, maternally derived antibodies induced by vaccination last for approx. 5-8 weeks after birth. In particular cases of multiple contacts of the sows with antigens (field infections + vaccination) the antibodies transmitted to the piglets may last until week 12 of life. In the latter case piglets should be vaccinated after the age of 96 days.
Overdose (symptoms, emergency procedures, antidotes), if necessary
After administration of a double dose (4 ml), no adverse reactions other than those described in Adverse events were observed.
Withdrawal period
Zero days
