Timing is everything when it comes to successful reproductive programs, and that includes timing of vaccinations to help prevent reproductive diseases.
Working with your veterinarian to set up vaccination programs and following labeled directions are key to vaccine efficacy and safety, especially when using modified-live virus (MLV) vaccines, says Victor Cortese, director of Veterinary Specialties Group for Pfizer Animal Health.
“MLV vaccines are safe to use, but there are risks involved when using them in pregnant cattle,” Cortese says. “Using these vaccines against their label indications and without supervision from a veterinarian are the biggest risks of all.” He recommends these tips for using MLV vaccines successfully:
• Regularly consult your veterinarian. Your veterinarian is a valuable resource regarding the science and proper use of vaccines. Include your veterinarian as part of your reproductive health team.
• Write vaccination programs. Having written programs, which include timing guidelines, for your vaccinations provides guidelines for you and anyone administering vaccines on your operation. Review them regularly with your employees and your veterinarian to help keep them up to date.
• Keep accurate records. Vaccine administrations should be included in your reproductive records. Record the date when the first vaccination is given and review the records to determine when a booster is needed.
