For the active immunization of fattening pigs from 3 weeks of age to reduce the occurrence and severity of lung lesions caused by Mycoplasma hyopneumoniae infection.

Onset of immunity: 3 weeks after the vaccination

Duration of immunity: 26 weeks after vaccination

4.3 Contraindications

None.

4.5 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, seek medical advice immediately and show the package leaflet or the label to the physician.

To the user:

This veterinary medicinal product contains mineral oil. Accidental injection/selfinjection may result in severe pain and swelling, particularly if injected into a joint or finger, and in rare cases could result in the loss of the affected finger if prompt medical attention is not given. If you are accidentally injected with this veterinary medicinal product, seek prompt medical advice even if only a very small amount is injected and take the package leaflet with you. If pain persists for more than 12 hours after medical examination, seek medical advice again.

To the physician:

This veterinary medicinal product contains mineral oil. Even if small amounts have been injected, accidental injection with this product can cause intense swelling, which may, for example, result in ischaemic necrosis and even the loss of a digit. Expert and PROMPT surgical attention is required and may necessitate early incision and irrigation of the injected area, especially where there is involvement of finger pulp or tendon.

4.6 Adverse reactions (frequency and seriousness)

On the day of vaccination a transient mean increase in body temperature of about 1.3°C is very common. In an individual pig this increase might reach 2^oC, but in all cases body temperature is back to normal the next day.

A local reaction at the site of injection in the form of a swelling of a diameter up to 5 cm can be very common, which can last for three days. These reactions are of transient nature and do not need further treatment.

Immediate mild hypersensitivity-like reactions may occur uncommonly after vaccination, resulting in transient clinical signs such as vomiting.

Serious anaphylactic-type reactions (shock, recumbency) which may be fatal have been reported very rarely from post-marketing surveillance. Such reactions require prompt symptomatic treatment.

The frequency of adverse reactions is defined using the following convention:

- very common (more than 1 in 10 animals treated displaying adverse reaction (s))

- common (more than 1 but less than 10 animals in 100 animals treated)

- uncommon (more than 1 but less than 10 animals in 1,000 animals treated)

- rare (more than 1 but less than 10 animals in 10,000 animals treated)

- very rare (less than 1 animal in 10,000 animals treated, including isolated reports).

4.7 Use during pregnancy, lactation or lay

Not applicable.

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 mixed with Circovac and administered to piglets at one injection site. Vaccinate piglets from 3 weeks of age.

Duration of immunity: at least 23 weeks when mixed with Circovac.

In case of mix with Circovac, commonly, an increase in individual rectal temperature of up to 2.5°C lasting less than 24 hours may occur. Slight and transient local reactions may occur after the administration, mainly swelling and redness as well as in some cases oedema. These reactions resolve spontaneously within maximum 4 days.

Read also the product information of Circovac before mixed use.

No information is available on the safety and efficacy of this vaccine when used with any other veterinary medicinal product, except when mixed with Circovac. 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

When Hyogen is used alone:

Intramuscular use.

Vaccinate pigs in the side of their neck.

Administer a single dose of 2 ml from 3 weeks of age.

The data available are not sufficient to exclude the interaction of maternally derived antibodies with vaccine uptake. Interaction with maternal-derived antibodies is known and should be taken into consideration. It is recommended to delay vaccination in piglets with residual MDA at the age of 3 weeks.

Shake well before use.

Use sterile syringe and needle, respect aseptic conditions of vaccination.

When Hyogen is mixed with Circovac:

Piglets from 3 weeks of age:

Hyogen	Circovac
100 doses (200 ml of vaccine)	100 doses for piglets (50 ml of reconstituted suspension + emulsion)

Vaccine devices should be used under aseptic conditions and in accordance with the device instructions provided by the manufacturer.

Prepare Circovac by shaking vigorously the vial of antigen suspension and injecting its content into the vial of emulsion containing adjuvant.

Mix 200 ml of Hyogen and 50 ml of Circovac and shake gently until a homogeneous white emulsion is obtained.

Administer one 2.5 ml dose of the mixture by deep intramuscular injection.

Use the entire vaccine mixture immediately after mixing. Read also the product information of Circovac before use.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

As the vaccine is inactivated, studies investigating the safety of an overdose administration are not required.

4.11 Withdrawal period(s) Zero days.

5. IMMUNOLOGICAL PROPERTIES

Pharmacotherapeutic group: Pig / Inactivated bacterial vaccines / mycoplasma ATCvet code: QI09AB13

Inactivated bacterial vaccine, containing whole cell concentrate of Mycoplasma hyopneumoniae strain 2940. This antigen is incorporated in an adjuvant for stimulation of immunity, based on a combination of light liquid paraffin and cell free Escherichia coli J5 LPS. The product stimulates the development of active immunity in pigs against Mycoplasma hyopneumoniae.

Under experimental conditions reduction of M. hyopneumoniae colonization was demonstrated 44-50 days post vaccination.
