Sheep Mastitis Vaccine

In ewes, bacterial mastitis is a financially significant problem, especially in dairy-type production systems . It is also a predominant cause of decreased welfare in sheep farms . For mastitis control, a variety of approaches, including correct management in the milking parlor  or administration of antibiotics at the end of a lactation period, can be applied; vaccination may also be implemented . Staphylococcus aureus is a main causal agent of clinical mastitis, particularly in dairy production type flocks . Coagulase-negative staphylococci (mainly Staphylococcus epidermidisStaphylococcus chromogenesStaphylococcus simulans, and Staphylococcus xylosus) are the primary etiological agents of subclinical mastitis

Sheep farmers battling ongoing mastitis rates of 10% or above could benefit from a new vaccine, which has been shown to halve incidence and improve recovery rates. Mastitis is one of the main causes of culling on farm. This, together with treatment costs and sub-optimal lamb growth rates due to reduced milk availability, makes it a costly problem. It is also a significant animal welfare issue.


  • For active immunisation of healthy ewes in flocks with recurring mastitis problems, to reduce the incidence of sub-clinical mastitis (reduction of udder lesions, somatic cell count and S. aureus count) caused by Staphylococcus aureus.
  • For active immunisation of healthy female goats in herds with recurring mastitis problems, to reduce the incidence of sub-clinical mastitis caused by Staphylococcus aureus and/or Coagulase-Negative Staphylococci; when clinical mastitis caused by Coagulase-Negative Staphylococci* however occurs, the severity of clinical signs (udder and milk aspect) is reduced.

Benefits of Sheep Mastitis Vaccine

The combination of the VIMCO® vaccination against Staphylococcal mastitis with a mastitis control program can lead to:

  • Fewer clinical and subclinical mastitis cases (minimizes the need for antibiotics and NSAIDs)
  • A reduction in the severity of clinical signs (udder and milk aspect)
  • Less discarded milk from high somatic cell counts
  • Less bacterial shedding
  • Fewer replacement animals required (fewer culls)
  • Increased profits from milk production, reduces milk loss (from SCC)
  • Healthier animals


Read all warnings and cautions on label. Animal use only.

Dosage & Administration

Give one dose (2ml) by deep intramuscular injection in the neck muscles at 5 weeks before the expected parturition date and 3 weeks after the first dose administer a second dose.

Allow the vaccine to reach a temperature of 15 – 250C before administration. Shake before use

Minimum age of vaccination; 8 months

The basic vaccination scheme is to be repeated prior to each lactation

The whole flock should be immunised
