Indications for use
For the active immunisation of pigs in order to reduce frequency and severity of lung lesions caused by Mycoplasma hyopneumoniae. For vaccination with 2 doses of 1 ml given 2-4 weeks apart, protection has been demonstrated 35 days post initial dose and the duration of immunity is at least 6 months. In field studies, only seroconversion has been demonstrated in pigs receiving two 1 ml doses. For vaccination with 1 dose of 2 ml, protection has been shown 24 days after vaccination and duration of immunity is at least 6 months after vaccination.
Special warnings for each target species
Piglets vaccinated from 7 days of age: Under laboratory conditions, piglets from 4 weeks of age after administration of 2 doses of 1 ml at 2-4 weeks interval produced a protective immune response in the presence of passively acquired antibodies. Furthermore, under field conditions piglets from 6 days old produced a serological response in the presence of such antibodies.
Piglets vaccinated from 21 days of age: Analysis of laboratory tests after the administration of a single 2 ml dose have shown no correlation between antibody level of maternal origin at the time of vaccination and the efficacy of vaccination; this suggests that maternally derived immunity in piglets does not interfere with vaccination.
Special precautions for use
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 product contains mineral oil. Accidental injection/self-injection may result in severe pain and swelling, particularly if injected into a joint or finger, and in rare case could result in the loss of the affected finger if prompt medical attention is not given. If you are accidentally injected with this 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 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, 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.
A small proportion of pigs may experience polypnea and dizziness within 5-10 minutes of first vaccination. This resolves within 4 hours without treatment or further adverse effect on the animal. An increase in respiration rate may also occur in a small proportion of piglets within a few hours of injection with either a 1 or 2 ml dose. Hyperthermia may occur in a small proportion of piglets given 1 ml (<39.8°C) and a higher proportion given 2 ml (mean 40.2°C), returning to normal within 24-48 hours. Adverse reactions are uncommon after the second vaccination. Local reactions at the injection site are common but are restricted to a slight swelling (<2 cm diameter) which disappears within 24-48 hours of injection. In rare cases a granuloma may occur in the muscle at the injection site which may last over 21 days but resolves over time. Correct aseptic technique will reduce this possibility further. [These observations were made during small scale laboratory studies and field trials]. In rare cases, emesis, dyspnoea, ataxia, muscle tremor, convulsion, diarrhoea, lethargy or anorexia may be observed following vaccination. In the event of hypersensitivity reactions (shock), appropriate treatment such as adrenaline should be administered without delay.
Use during pregnancy, lactation or lay
The use is not recommended during pregnancy or lactation.
No information is available on the safety and efficacy from the concurrent use of this vaccine with any other. It is therefore recommended that no other vaccines should be administered within 14 days before or after vaccination with this product.
Amounts to be administered and administration route
Pigs from 7 days of age: 1 dose of 1 ml. This 1 ml dose should be repeated after 14 – 28 days. Pigs from 21 days of age : 1 single dose of 2 ml or 2 doses of 1 ml administered at an interval of 14-28 days. Vaccinate pigs by the intramuscular route, preferably on alternate sides of the neck. The vial should be well shaken before withdrawing a dose. There is no need to warm the vaccine before use. Syringes and needles must be sterile before use. The injection should be performed in a clean and dry skin area, taking appropriate precaution to avoid contamination. Follow usual aseptic procedures.
No additional undesirable side effects other than those mentioned in section “Adverse reactions” have been observed after the administration of 4 ml of the vaccine.
