The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Startvac exceed the risks 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 severity of the clinical signs of clinical mastitis caused by Staphylococcus aureus, coliforms and coagulase-negative staphylococci, and recommended that Startvac be given a marketing authorisation.
