The Vaccines Every Texas Herd Needs
Every cattle operation has unique needs, but certain vaccines form the foundation of any effective herd health program in Texas. These "core" vaccines protect against diseases that are either universally present, highly fatal, or cause significant economic losses. Skipping core vaccinations is not a gamble. It is a guarantee of eventual loss.
This guide covers the vaccines every Texas beef cattle operation should consider, with specific attention to regional disease pressures and management considerations.
Tier 1: Essential Core Vaccines
Clostridial Vaccines (7-Way or 8-Way)
| Disease | Organism | Key Signs | Notes |
|---|---|---|---|
| Blackleg | C. chauvoei | Sudden death, swollen muscles | Most common in young cattle |
| Malignant Edema | C. septicum | Wound infections, swelling | Often post-injury or castration |
| Black Disease | C. novyi | Liver damage, sudden death | Associated with liver flukes |
| Red Water | C. haemolyticum | Bloody urine, death | More common in wet areas |
| Enterotoxemia | C. perfringens C&D | Sudden death, digestive upset | Grain-fed cattle higher risk |
| Tetanus | C. tetani | Muscle stiffness, "lockjaw" | After wounds, castration |
| Sordellii | C. sordellii | Sudden death, edema | Added in 8-way products |
Schedule an annual booster for all cattle at a cost of $1.50 to $3.00 per dose.
Respiratory Virus Complex (4-Way or 5-Way Viral)
| Disease | Organism | Primary Effects | Texas Relevance |
|---|---|---|---|
| IBR | Bovine Herpesvirus-1 | Respiratory, abortion | Major concern statewide |
| BVD Types 1 & 2 | Pestivirus | Immunosuppression, reproductive loss | Extremely important |
| PI3 | Parainfluenza-3 | Respiratory disease | Common respiratory component |
| BRSV | Respiratory Syncytial Virus | Severe pneumonia | Often most severe in calves |
Modified-live vaccines (MLV) provide strong, broad immunity but are not safe for most pregnant animals. Killed vaccines are safe for pregnant animals but require boosters for full protection.
Give cows an annual booster 30 or more days pre-breeding, and vaccinate bulls annually before breeding season.
Tier 2: Highly Recommended Vaccines
Leptospirosis (5-Way Lepto)
A 5-way lepto vaccine covers L. hardjo (most common in cattle), L. pomona, L. grippotyphosa, L. canicola, and L. icterohaemorrhagiae. Wet years increase exposure dramatically in Texas, and wildlife (deer, feral hogs) serve as reservoirs. East Texas and the Gulf Coast carry higher risk. Administer 30 or more days before breeding season, often combined with viral vaccines for convenience.
Vibriosis (Campylobacter fetus)
Multi-sire pastures increase exposure risk, making this vaccine essential for most commercial operations. Cows get an annual booster pre-breeding, and bulls need annual vaccination as well.
Mannheimia haemolytica (Pasteurella)
Often available in combination viral-plus-bacterial products. High-stress operations need strong protection, and feedyard cattle especially benefit. For received cattle, administer at processing and booster 2 to 3 weeks later.
Tier 3: Risk-Based Vaccines
Anaplasmosis
Risk varies by region across Texas: the Gulf Coast is high-risk, Central Texas moderate, South Texas moderate to high, and West Texas/Panhandle generally lower. The available vaccine can cause disease if used incorrectly, and anaplasmosis is often managed with feed additives (CTC) instead. This is not a universal recommendation, so discuss your specific risk with your veterinarian.
Pinkeye (Moraxella bovis)
Risk factors include tall grass and seed heads, UV exposure, and lack of eye pigmentation. Multiple strains exist, and vaccines may not match the strain causing problems on your ranch. Autogenous (herd-specific) vaccines are sometimes used. Management practices like fly control and pasture mowing are equally important. Consider your herd history when deciding whether to include this vaccine.
Anthrax
Anthrax endemic areas in Texas include Southwest Texas (Val Verde, Edwards, Real counties), parts of the Hill Country, and areas with alkaline, limestone soils. Vaccinate annually in April or May, before the hot, dry season. Use only the licensed Sterne strain vaccine. First vaccination is given at 3 or more months of age, and do not vaccinate within 42 days of slaughter.
Trichomoniasis
Testing and culling positive bulls is more effective than vaccination for controlling trichomoniasis. Vaccination may provide some protection in heifers, and some operations require vaccination as an additional precaution.
Scours (Calf Diarrhea) Vaccines
Pre-Calving Cow Vaccination
Scours vaccines protect against rotavirus, coronavirus, and Clostridium perfringens Type C. For first-calf heifers, give two doses with the initial dose early in the third trimester, then follow up 2 to 4 weeks before calving per label directions. Annual vaccination is recommended for all pregnant females.
These vaccines are particularly valuable for operations with a history of scours problems or concentrated calving in muddy conditions.
Texas-Specific Disease Considerations
Regional Disease Pressure Map
| Region | Primary Concerns | Additional Considerations |
|---|---|---|
| Panhandle | Respiratory, clostridial | Less anaplasmosis, fewer ticks |
| North Texas | Full spectrum | Moderate all risks |
| East Texas | Anaplasmosis, lepto | High tick populations |
| Central/Hill Country | Anthrax (areas), respiratory | Diverse terrain |
| South Texas | Anaplasmosis, ticks | Heat stress compounds disease |
| Gulf Coast | Lepto, anaplasmosis | Flooding, wet conditions |
| West Texas | Clostridial, respiratory | Desert-adapted pathogens |
Seasonal Timing for Texas
Spring is the time for bull vaccination, anthrax in endemic areas (April-May), and calf first-round vaccines in late spring. Summer calls for pinkeye vaccination if used and close monitoring for anaplasmosis. Fall is the season for pre-conditioning programs with a respiratory focus. Winter brings reduced disease pressure overall, making it a good time to plan the spring program.

Working with Texas Veterinarians
Finding a Beef Cattle Veterinarian
Good sources include local cattlemen's associations, county Extension agents, and auction market veterinarians. Ask other ranchers in your area who they trust.
Questions for Your Texas Vet
- What diseases are you seeing locally this year?
- Are there any regional alerts I should know about?
- What's your recommendation for anaplasmosis in my area?
- Should I consider anthrax vaccination?
- What are you seeing in terms of BVD-PI animals?
Veterinarian-Client-Patient Relationship (VCPR)
A VCPR enables extra-label drug use, health certificates, and disease consultation. Maintain the relationship through regular consultations, emergency availability, and records review.
Regulatory Considerations for Texas
Required Vaccinations
Brucellosis vaccination for heifers is required. Official vaccinates must be done by an accredited veterinarian, and an ID ear tag and registration are required. This is essential for interstate movement.
Movement and Sale Requirements
Trichomoniasis testing is required for bulls, and health certificates are needed for interstate movement. Market premiums for vaccinated cattle provide a real financial incentive, and preconditioned programs have specific vaccination requirements.
Frequently Asked Questions
Bottom Line
Clostridial vaccines are non-negotiable for every Texas operation. Seven-way protection covers diseases that are present in every pasture across the state, and the cost per dose is minimal compared to losing even one animal. Respiratory vaccines are equally essential because BRD is too common and too costly to leave to chance.
Regional risks vary significantly across Texas. An East Texas operation dealing with heavy tick pressure and anaplasmosis has a different vaccine card than a Panhandle stocker yard focused on respiratory disease. Know your area's specific threats and build your program around them.
Your vet knows what is circulating in your neighborhood better than any general guide can tell you, so lean on that relationship. Document your program and review it annually, tracking results so you can adjust when conditions change.
