Contains a specially prepared, inactivated and adjuvanted unique strain of Leptospira borgpetersenii serovar hardjo-bovis together with inactivated and adjuvanted cultures of L. pomona, L. grippotyphosa, L. canicola and L. icterohaemorrhagiae.
For vaccination of healthy cattle, including pregnant cows and heifers, over 4 weeks of age, as an aid in preventing disease caused by the above organisms. In addition, it is especially recommended to prevent establishment of L. hardjo in the kidney, and thus shedding in the urine, for at least 12 months. Spirovac L5 also prevents the establishment of L. hardjo in the genital tract and aids in preventing infection of the fetus.
General Directions: Aseptically administer 2 mL subcutaneously or intramuscularly in the neck.
Primary Vaccination: Healthy cattle should receive 2 doses administered 4-6 weeks apart with booster doses given as necessary. When used as an aid in preventing genital or fetal infection, booster doses should be completed at least 2 weeks prior to breeding. Primary vaccination with this product in calves from 4 weeks of age with a second dose 4-6 weeks later will prevent infection, colonization and subsequent shedding of serovar hardjo-bovis, a source of further infection in the herd.
Revaccination: Annual revaccination with a single dose is recommended. Include all bulls in programs of vaccination. As part of normal biosecurity procedures, all replacement animals should begin a two-dose course of vaccination upon arrival.
