Lambivac^® Questions and Answers

For the active immunisation of sheep to:

• Reduce clinical signs and mortality due to the toxin of Clostridium tetani (Tetanus);
• Reduce mortality due to the epsilon toxin of Clostridium perfringens (Pulpy kidney);
• Induce a serological response against the beta toxin of Clostridium perfringens (Struck, Lamb dysentery).

The vaccine may be used in pregnant ewes to provide passive immunisation of lambs, provided that the lambs receive sufficient immune colostrum during the first 12 hours of life, to:

• Reduce clinical signs and mortality due to the toxin of Clostridium tetani (Tetanus);
• Reduce mortality due to the epsilon toxin of Clostridium perfringens (Pulpy kidney);
• Induce a serological response against the beta toxin of Clostridium perfringens (Lamb dysentery).  

Significant levels of immunity cannot be expected until two weeks after the second dose of vaccine in the primary vaccination course.  

From experience from field use, the duration of active immunity in lambs and sheep is expected to last one year.

The duration of passive protection in lambs is approximately 12 weeks provided that the lambs receive sufficient immune colostrum during the first 12 hours of life.
