Vaccine Use: Key Points
§ Keep records § Read the product
label § Understand the
products § Understand
population dynamics
3
Records: The basics
§ Who? § Animal identification
number
§ What? § Product name § Serial number § Expiration date § Storage conditions
§ When? § Date used § Is a booster required?
§ Where? § Dose § Route of administration
§ How? § Make it mobile for easy
transfer to the next owner 4
Example: Cattle Vaccine Label
Indications: For vaccination of healthy, non-pregnant cattle, 3 months of age or older, as an aid in prevention of disease caused by infectious bovine rhinotracheitis virus (IBR), bovine virus diarrhea virus (BVD) (Type 2), & bovine respiratory syncytial virus (BRSV), & as an aid in control of disease caused by bovine virus diarrhea virus (BVD) (Type 1) & parainfluenza3 virus (Pl3). Respiratory duration of immunity (DOI) has been demonstrated to be at least one year for IBR, BVD (Type 1) & BVD (Type 2). Calves nursing immune-dams should be vaccinated when maternal antibody levels will allow active immunization. Directions &Dosage: Rehydrate freeze dried vial of Vista® 5 SQ with part of enclosed diluent using transfer needle provided (see insert for pictorial directions); shake well. Transfer rehydrated vaccine into diluent vial using transfer needle. Remove transfer needle from former diluent vial; shake well. Peel label from Vista® 5 SQ vial & place on diluent vial containing all vaccine. Inject 2.0 mL SQ. Annual revaccination is recommended. A revaccination dose can be administered at more frequent intervals based upon individual farm disease risk assessment or any time epidemic conditions exist or are reported. Consult your veterinarian. Cautions: Store refrigerated at 35°- 45°F (2°- 7°C). Do not freeze. Use immediately after reconstitution; do not save partial contents. Burn containers & all unused product. Use only in healthy cattle. Do not vaccinate within 21 days before slaughter. Do not use in pregnant cows or in calves nursing pregnant cows. If allergic reaction occurs, treat with epinephrine. Contains penicillin & streptomycin as preservatives.

Understanding the product § Why do you want to use it?
§ Prior disease, risk management, customer demands § Not all products are the same
§ killed v. live, adjuvated, method of manufacturing, contents, compatibility with other products
§ Duration of protection § Ex: IBR v. BRSV, Ex: Pinkeye vaccines
§ Side effects § Injection site reaction, endotoxins, reproductive consequences, anaphylactic
reactions, immunosuppression, establishment of latent infections § Speed of action
§ IN viruses § start protection within hours
– SQ live viruses § start protection within days
– SQ bacterins § start protection within weeks

Population Management: Age
§ Immune systems are different § Disease challenges are different § Goals following use are different § Vaccine selection is different § Every cow herd is different § Every year is different

Goals for young calf
§ Protect the critical first two months
§ Transition from passive immunity to active immunity
§ Establish a high level of protective immunity through weaning
§ Prepare for market place

Goals for Heifers § Establish long-term immunity § Protect first pregnancy § Enhance collective herd immunity
11
Goals for Cows § Establish collective herd immunity § Protect the pregnancy § Establish immunity in the offspring
12
Goals for sire battery
