With weaning time here, keep Beef Quality Assurance guidelines top of mind. Here are some basic vaccine-handling precautions to ensure effectiveness of the vaccine:
1) Read the label.
2) Purchase fresh vaccines and store them in a refrigerator. Never use an outdated drug or vaccine.
3) Modified-live vaccine begins to lose effectiveness after about an hour, so don’t mix too much vaccine at one time. Because direct sunlight also degrades the products, keep vaccines and syringes in a cooler when working cattle.
4) Don’t use the same syringe to inject modified-live and killed products. A trace of killed product can harm modified-live product effectiveness.
