Cows and Heifers: To prevent mastitis.

  • For herd immunisation of healthy cows and heifers, in dairy cattle herds with recurring mastitis problems, to reduce the incidence of sub-clinical mastitis and the incidence and the severity of the clinical signs of clinical mastitis caused by Staphylococcus aureus, coliforms and coagulase-negative staphylococci.
  • The full immunisation scheme induces immunity from approximately day 13 after the first injection until approximately day 78 after the third injection (equivalent to 130 days post-parturition).
  • It can be used during pregnancy and lactation.



  • Slight to moderate transient local reactions may occur after the administration of the vaccine, which disappears within 1 or 2 weeks at most.



Intramuscular, into the neck muscles.

  • The injections should be preferably administered on the alternate sides of the neck.
  • Administer the vaccine at a room temperature between +15 and +25 ºC.
  • Shake before use.



Cows and Heifers: 2 ml/animal.

  • Intramuscular use. The injections should be preferably administered on the alternate sides of the neck. Allow the vaccine to reach a temperature of +15 to + 25 °C before administration. Shake before use.

  • Administer one dose (2 ml) by deep intramuscular injection in the neck muscles at 45 days before the expected parturition date and 1 month thereafter administer a second dose (at least 10 days before calving). A third dose should be administered 2 months thereafter.

  • The whole herd should be immunised. Immunisation has to be considered as one component in a complex mastitis control program that addresses all important udder health factors (e.g. milking technique, dry-off and breeding management, hygiene, nutrition, bedding, cow confort, air and water quality, health monitoring) and other management practices.



0 days.



  • Store at +2 to +8 ºC, avoiding freezing. Protect from light.
