Introduction to Cattle Vaccination
A comprehensive vaccination program is the cornerstone of preventive cattle health management. Proper immunization protects your herd from devastating diseases that can cause mortality, reduced productivity, reproductive failures, and significant economic losses. This guide provides a complete vaccination timeline from birth through adulthood, helping you build an effective disease prevention strategy for both beef and dairy operations.
Vaccination schedules must be tailored to your specific operation, considering factors such as geographic location, disease prevalence in your region, herd management practices, and whether you're raising beef or dairy cattle. While this guide provides comprehensive recommendations, always consult with your veterinarian to develop a customized protocol that addresses your herd's unique needs and local disease challenges.
Why Vaccination is Critical
Vaccination is one of the most cost-effective health management tools available to cattle producers. The investment in vaccines is minimal compared to the potential losses from disease outbreaks, which can include death loss, treatment costs, reduced weight gains, poor reproductive performance, and decreased milk production.
Economic Benefits of Vaccination
Studies consistently show that properly vaccinated cattle perform better economically. Vaccinated calves gain weight more efficiently, experience fewer respiratory infections, and command higher prices at sale. In dairy operations, vaccination programs reduce mastitis incidence, improve reproductive efficiency, and increase milk production by preventing disease-related losses.
| Disease | Without Vaccination | With Proper Vaccination | ROI |
|---|---|---|---|
| Bovine Respiratory Disease | 15-45% morbidity, $500+ treatment cost | 5-10% morbidity, reduced severity | $15-$30 per $1 spent |
| Clostridial Diseases | High mortality (blackleg ~100%) | Near complete protection | $50+ per $1 spent |
| Reproductive Diseases | 20-40% calf loss, open cows | 3-8% loss, improved conception | $20-$40 per $1 spent |
| Scours (Calf Diarrhea) | 10-20% mortality, stunted growth | 2-5% mortality, better gains | $10-$25 per $1 spent |
Disease Prevention Beyond Economics
Beyond financial benefits, vaccination reduces antimicrobial use, improves animal welfare, decreases labor requirements for treating sick cattle, and enhances your operation's biosecurity. A well-vaccinated herd is more resilient to disease challenges and stress, particularly during high-risk periods like weaning, transport, and weather extremes.
Types of Cattle Vaccines
Understanding vaccine categories helps you prioritize your vaccination program and budget appropriately. Vaccines are generally classified into three categories based on their importance and applicability.
CORE VACCINES
Essential for all cattle regardless of location or management system.
- Clostridial Vaccines (7-way or 8-way): Protects against blackleg, malignant edema, and other clostridial diseases that cause sudden death
- IBR (Infectious Bovine Rhinotracheitis): Prevents respiratory disease and abortion
- BVD (Bovine Viral Diarrhea): Prevents immune suppression, respiratory disease, and reproductive failures
- PI3 (Parainfluenza-3): Protects against respiratory infections
- BRSV (Bovine Respiratory Syncytial Virus): Reduces respiratory disease severity
OPTIONAL VACCINES
Recommended based on herd management and disease risk.
- Mannheimia haemolytica: Bacterial pneumonia prevention for high-risk cattle
- Pasteurella multocida: Additional respiratory protection
- Mycoplasma bovis: For operations with mycoplasma history
- Campylobacter fetus (Vibriosis): For breeding bulls and females
- Leptospirosis: Prevents reproductive losses and milk drop
- Haemophilus somnus: For feedlot or high-density operations
REGIONAL VACCINES
Required or recommended only in specific geographic areas.
- Anaplasmosis: For areas with endemic anaplasmosis
- Trichomoniasis: Required for bulls in some states
- Anthrax: For endemic regions with soil contamination
- Rabies: For areas with high wildlife exposure
- Brucellosis (calfhood vaccination): Where still required by state regulations
Complete Vaccination Timeline
The following timeline provides a comprehensive vaccination schedule from birth through adulthood. This schedule can be adapted for both beef and dairy operations, with modifications noted where protocols differ significantly.
Calf Vaccination Program (Birth - 6 Months)
Immediate Colostrum Management
Not a vaccine, but critical: Ensure calves receive adequate colostrum within the first 6 hours of life. Calves should consume 10-12% of body weight in high-quality colostrum within the first 12-24 hours.
- Test colostrum quality (Brix refractometer ≥22%)
- Feed 4 quarts within first 2 hours
- Second feeding at 8-12 hours
- Consider maternal antibody transfer testing
First Clostridial Vaccine
7-way or 8-way Clostridial vaccine
- Protects against blackleg, malignant edema, black disease, red water, enterotoxemia
- Especially important if calves have pasture access
- Booster required in 2-4 weeks
Optional at this age: Intranasal IBR-PI3 for high-risk calves or early weaning situations
Clostridial Booster
- Complete the 7-way or 8-way clostridial series
- Essential for full immunity development
First Modified-Live or Killed Virus Vaccines
Respiratory Vaccine Series Start:
- IBR (Infectious Bovine Rhinotracheitis)
- BVD Types 1 & 2 (Bovine Viral Diarrhea)
- PI3 (Parainfluenza-3)
- BRSV (Bovine Respiratory Syncytial Virus)
Additional Considerations:
- Many producers use a 5-way viral vaccine (IBR-BVD-PI3-BRSV)
- Intranasal vaccines can be given as early as 1 week of age if needed
- Injectable vaccines typically start at 2-3 months
- Booster in 2-4 weeks before weaning stress
Common Vaccination Point
Many beef operations use branding/processing time for initial vaccinations:
- 7-way Clostridial vaccine (if not done earlier)
- 5-way viral respiratory vaccine (first dose)
- Optional: Pasteurella/Mannheimia if high risk
Weaning and Growing Cattle (6-12 Months)
Weaning is the highest-stress period in a calf's life, making it a critical time for immune protection. Ideally, calves should receive their vaccine booters 2-4 weeks BEFORE weaning to allow immunity to develop before stress suppresses the immune system.
Pre-Weaning Booster (Ideal Timing)
- Respiratory vaccine booster: IBR-BVD-PI3-BRSV (5-way viral)
- Clostridial booster: 7-way or 8-way
- Optional additions:
- Mannheimia haemolytica/Pasteurella multocida for pneumonia prevention
- Haemophilus somnus if going to feedlot
- Mycoplasma bovis in endemic areas
Weaning Vaccination
If pre-weaning vaccination wasn't possible:
- 5-way viral respiratory vaccine
- 7-way Clostridial
- Bacterial respiratory vaccines (Mannheimia/Pasteurella)
Important: Minimize stress on vaccination day. Provide adequate nutrition, clean water, and comfortable environment.
Post-Weaning Booster
- Booster respiratory vaccines if initial dose given at weaning
- This completes the primary immunization series
- Critical for developing lasting immunity
Additional Considerations
- Implants (if part of your program)
- Deworming protocols
- External parasite control
- Monitor for respiratory disease
| Vaccine | Primary Series | Booster Timing | Notes |
|---|---|---|---|
| IBR-BVD-PI3-BRSV | 2 doses, 2-4 weeks apart | Before weaning stress | Use MLV for best protection; killed for pregnant females |
| 7-way Clostridial | 2 doses, 2-4 weeks apart | Complete before 6 months | Annual boosters thereafter |
| Mannheimia/Pasteurella | 1-2 doses depending on product | At weaning or pre-weaning | Especially important for purchased/commingled calves |
| Haemophilus somnus | 1-2 doses | Before feedlot entry | More common in feedlot situations |
Breeding Stock Vaccination
Proper vaccination of breeding animals is essential for protecting both the animals and their offspring. Timing vaccinations relative to breeding season is critical to avoid reproductive interference while ensuring maximum protection.
Replacement Heifers (Pre-Breeding)
30-60 Days Before Breeding Season
- Reproductive Disease Vaccines:
- IBR-BVD-PI3-BRSV (killed virus for pregnant females, MLV for open)
- Vibriosis (Campylobacter fetus)
- Leptospirosis (5-way including hardjo-bovis)
- 7-way Clostridial booster
Breeding Bulls
Annual Pre-Breeding Vaccination
- IBR-BVD-PI3-BRSV (MLV vaccine acceptable)
- 7-way or 8-way Clostridial
- Vibriosis (Campylobacter fetus) - REQUIRED in many states
- Leptospirosis 5-way
- Trichomoniasis testing and vaccination where required
Timing: Complete vaccinations 30-60 days before breeding season begins to ensure immunity is established.
Mature Cows
Cow vaccination programs protect both the cow and provide passive immunity to calves through colostrum. Proper timing relative to calving is essential.
| Timing | Vaccines | Purpose |
|---|---|---|
| 30-60 days pre-breeding | IBR-BVD-PI3-BRSV (killed), Vibrio, Lepto 5-way, 7-way Clostridial | Protect reproductive performance, prevent abortions |
| 30-60 days pre-calving | Scours vaccine (E. coli, Rotavirus, Coronavirus), 7-way Clostridial booster | Transfer antibodies to calf via colostrum |
| At pregnancy check | 7-way Clostridial (if not done at breeding) | Maintain immunity through gestation |
| Post-calving | IBR-BVD booster (if not done pre-breeding) | Restore immunity after calving stress |
Adult Cattle Maintenance
Adult cattle require annual vaccination maintenance to sustain protective immunity. The specific schedule depends on whether you're managing beef or dairy cattle and your production system.
Beef Cattle Annual Protocol
Once Yearly Maintenance
- Spring (30-60 days pre-breeding):
- IBR-BVD-PI3-BRSV (killed virus for pregnant cows)
- 7-way Clostridial
- Vibriosis (breeding animals)
- Leptospirosis 5-way
- Fall/Winter (pre-calving):
- Scours vaccine (E. coli, Rotavirus, Coronavirus)
- 7-way Clostridial booster (optional, depending on program)
Dairy Cattle Annual Protocol
Routine Maintenance Schedule
- Pre-Breeding/Early Lactation:
- IBR-BVD-PI3-BRSV (killed virus)
- Leptospirosis 5-way
- Vibriosis (some herds)
- Dry Cow Period:
- Scours vaccine (coliform mastitis-scours combination products available)
- E. coli J5 mastitis vaccine (some operations)
- 7-way Clostridial (annually)
- Fresh Cow Period:
- Monitor for disease, minimize stress
- Some dairies vaccinate fresh cows with respiratory vaccines
Stocker/Feedlot Cattle
Purchased cattle entering backgrounding or feeding programs require special attention due to stress and disease exposure.
Arrival Processing
- IBR-BVD-PI3-BRSV (often use MLV for maximum protection)
- 7-way Clostridial
- Mannheimia haemolytica/Pasteurella multocida
- Haemophilus somnus
- Mycoplasma bovis (if available and indicated)
Booster Timing: Revaccinate in 14-21 days for cattle with unknown vaccination history
Vaccination Best Practices
Proper vaccine handling and administration is just as important as choosing the right vaccines. Poor technique can result in vaccine failure, injection site reactions, and wasted investment.
Vaccine Storage and Handling
- Store vaccines at 35-45°F (2-7°C) - never freeze or overheat
- Transport vaccines in coolers with ice packs, not directly on ice
- Check expiration dates before use - never use expired vaccines
- Protect vaccines from sunlight and heat during administration
- Mix only the amount you can use within the recommended time frame
- Use separate needles for each animal to prevent disease transmission
- Change needles every 10-15 animals or when contaminated/bent
Injection Techniques
| Route | Location | Needle Size | Best For |
|---|---|---|---|
| Subcutaneous (SQ) | Neck, in front of shoulder | 16-18 gauge, ½-¾ inch | Most killed vaccines, some MLV |
| Intramuscular (IM) | Neck only (never hindquarters) | 16-18 gauge, 1-1½ inch | Some MLV vaccines, antibiotics |
| Intranasal | Nasal passages | Special applicator | Young calves, rapid immunity needed |
Timing Considerations
- Vaccinate during cool parts of the day when possible
- Avoid vaccinating sick, stressed, or extremely thin cattle
- Allow 2-3 weeks between vaccination and stressful events
- Don't vaccinate within 21 days of slaughter (check withdrawal times)
- Complete vaccine series - don't skip boosters
- Vaccinate before disease exposure, not during outbreaks
Record Keeping
Maintain detailed vaccination records including:
- Date of vaccination
- Product name and manufacturer
- Serial/lot number
- Expiration date
- Animal identification
- Route and location of administration
- Person administering vaccine
Good records help you evaluate program effectiveness, comply with quality assurance programs, and provide documentation for buyers.
Regional and Seasonal Considerations
Vaccine programs must be adapted to regional disease challenges, climate conditions, and local management practices. Consult with your veterinarian and local extension specialists to identify specific risks in your area.
Geographic Disease Variations
| Region | Specific Concerns | Additional Vaccines |
|---|---|---|
| Southern US | Anaplasmosis, higher parasite loads | Anaplasmosis vaccine, aggressive parasite control |
| Northern Plains | BVD, IBR, respiratory disease | Enhanced respiratory protocols |
| Western States | Trichomoniasis, high altitude stress | Trich testing/vaccination for bulls |
| Humid Regions | Increased pinkeye, foot rot | Pinkeye vaccine, footbath programs |
| Endemic Areas | Anthrax, Johne's disease | Consult state veterinarian for requirements |
Seasonal Management

- Pre-weaning boosters (September-October)
- Wean calves (October-November)
Fall Calving Operations
- Vaccinate cows pre-calving (June-August)
- Process calves (September-November)
- Pre-weaning boosters (March-April)
- Wean calves (April-May)
Frequently Asked Questions
The optimal vaccination schedule depends on your management system, but research shows the best approach is a three-step program: (1) Initial vaccination at 2-4 months (branding time for many operations), (2) Booster 2-4 weeks before weaning stress, and (3) Final booster 2-4 weeks after weaning. This provides maximum protection during the high-stress weaning period. Vaccinating only at weaning is less effective because stressed calves don't respond as well to vaccines. Never rely on a single vaccination at any age - the primary series requires at least two doses for most vaccines.
Generally, NO - do not use MLV vaccines containing IBR or BVD on pregnant cattle unless the product is specifically labeled as safe for pregnant animals. MLV vaccines can cause abortions, fetal infections, and birth defects when given to pregnant cows. Always use killed virus vaccines for bred females. The exception is if your herd has been consistently vaccinated with the same MLV vaccine before breeding, you may be able to use certain MLV products - but consult your veterinarian first. When in doubt, use killed virus vaccines for any potentially pregnant female.
A comprehensive vaccination program typically costs $15-35 per calf annually, depending on the vaccines used and your management system. This includes: Clostridial vaccines ($3-5), respiratory virus vaccines ($5-12), bacterial respiratory vaccines ($4-8), and reproductive disease vaccines for breeding stock ($6-10). While this may seem like a significant expense, the return on investment is substantial - every dollar spent on vaccination typically returns $15-50 in prevented disease costs, improved weight gains, and reduced death loss. The cost of treating a single case of pneumonia ($200-500) or losing one calf ($800-1200) far exceeds the annual vaccination cost for your entire herd.
Yes, absolutely. Cattle with unknown or questionable vaccination history should receive a complete primary vaccination series upon arrival. This means administering vaccines on day 1 (arrival) and then boostering 14-21 days later. Even if sellers claim cattle were vaccinated, you cannot verify the timing, products used, or proper handling of those vaccines. High-risk cattle (auction market, commingled, transported long distances) should receive comprehensive vaccination including both viral and bacterial respiratory protection. Many veterinarians also recommend metaphylactic antibiotics for extremely high-risk cattle during the first 3-5 days. The cost of revaccination is minimal compared to the risk of disease outbreak in unprotected cattle.
Wait until cattle recover before vaccinating. Sick cattle have compromised immune systems and will not respond properly to vaccines. Vaccinating sick animals wastes money and provides false confidence in protection that doesn't exist. Additionally, the stress of handling sick cattle for vaccination can worsen their condition. The exception is when using intranasal vaccines for immediate local immunity in face of a disease outbreak, but this should only be done under veterinary guidance. If cattle become sick shortly after purchase, focus on treatment first, then complete the vaccination program once they've recovered. Prevention is always better than treatment - this is why pre-conditioning programs that vaccinate cattle before the stress of weaning and shipping are so valuable.
