For the active immunisation of susceptible breeding female sheep against Chlamydophyla abortus infection, as an aid in the prevention of abortion caused by this organism.  Studies to date indicate that the protection afforded should exist for at least 771 days post-initial vaccination.

Do not administer to unhealthy animals.  Do not use in cases of hypersensitivity to the adjuvant or any of the excipients.

Some animals in any given population may not respond to    vaccination as a result of immunosuppression or for other reasons.

The safety and efficacy of Mydiavac administered to pregnant  sheep has been studied in challenge experiments.  These studies have demonstrated the safety of this practice.  A reduction in abortion and infection was evident in pregnant ewes challenged following vaccination and in pregnant ewes vaccinated after challenge.  On the basis of this evidence, Mydiavac could be used as an aid in the control of Chlamydophyla abortus infection, even in the face of an outbreak.  Mydiavac must not be administered concomitantly with live Toxoplasma gondii  vaccines to pregnant  animals.

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 a commercial Toxoplasma gondii vaccine containing live tachyzoites of the S48 strain.  Simultaneous administration of Mydiavac and such a commercial Toxoplasma gondii vaccine does not significantly affect the serological effect to either vaccine or cause any ill effects provided separate syringes and different sites of injection are used.

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

Withdrawal period
Zero days.  However, if a live Toxoplasma gondii vaccine has been administered concomitantly, the withdrawal period applicable to that vaccine  should apply.

Store and transport between 2° and 8°C. 
Do not freeze.
