Complete Cattle Vaccination Schedule for Beef & Dairy (2027 Guide)
Quick answer: A properly designed cattle vaccination program returns roughly $4–$6 per dollar spent through reduced disease. This guide covers the full annual schedule for beef cow-calf, dairy, bulls, and replacement heifers — with age-by-age timing, vaccine types, and typical costs. Core vaccines are given annually to the mature herd, with additional boosters at branding, weaning, and 30–60 days before breeding. Calves start at 2–4 months and receive a pre-weaning booster.
The Core Vaccines Every Herd Needs
Every U.S. cattle operation, regardless of region or size, should build its protocol around the same set of core vaccines. These protect against the diseases most likely to cause economic loss on any operation. Regional additions (anaplasmosis in the South, foot rot in wet climates, specific leptospirosis serovars) are layered on top of this core.
| Vaccine | Protects Against | Class Given To |
|---|---|---|
| 7-way Clostridial | Blackleg, malignant edema, enterotoxemia, tetanus | All calves at branding |
| Respiratory 5-way (IBR/BVD/PI3/BRSV + Mannheimia) | BRD complex, viral pneumonia | Calves, cows, bulls |
| Vibrio + Lepto 5-way | Reproductive loss, kidney damage | Cows & bulls, pre-breeding |
| Scours vaccine | E. coli, rota/corona virus, clostridium | Pregnant cows, 30–90 days pre-calving |
| Brucellosis (Bang's) | Reproductive disease, zoonotic | Heifers 4–12 months (mandatory in many states) |
| Trichomoniasis | Reproductive failure | Bulls in endemic regions |
Modified-live vaccines (MLV) give stronger, longer immunity but should NOT be given to pregnant cows unless they were previously vaccinated with the same MLV product. Killed vaccines are safer for pregnant animals but require two doses initially for full immunity. Read every label carefully — this is where most on-farm vaccine accidents happen.
Beef Cow-Calf Vaccination Schedule
| Age / Stage | Vaccine | Purpose | Timing Notes |
|---|---|---|---|
| Newborn (0–24 hr) | Colostrum from vaccinated dam | Passive immunity to all maternal diseases | Within 6 hours of birth |
| Branding (2–4 months) | 7-way Clostridial + Respiratory 5-way (MLV) | Blackleg, viral respiratory disease | Single dose at branding |
| Pre-weaning (45–60 days before) | Booster 7-way + Respiratory 5-way + Mannheimia | Weaning-stress BRD prevention | 3–6 weeks pre-wean |
| Weaning | Second respiratory booster | Complete BRD immunity | At weaning |
| Yearling heifers | Brucellosis (RB51) | Brucellosis, reproductive loss | 4–12 months (state-mandated) |
| Pre-breeding heifer | Scours vaccine + Vibrio + Lepto 5-way + Respiratory 5-way | Reproductive protection | 30 days pre-breeding |
| Mature cows — annual | Respiratory 5-way + Vibrio/Lepto + Scour Guard | Core protection | 60 days pre-breeding + 60 days pre-calving |
| Bulls — annual | Respiratory 5-way + Vibrio + Lepto + Trich (endemic areas) | Prevent disease transmission at breeding | 30–60 days pre-breeding |
Dairy Vaccination Schedule
Dairy operations follow a similar framework but with tighter timing driven by lactation and freshening cycles. Because dairy cows are handled far more frequently than beef cows, additional vaccines are practical.
| Age / Stage | Vaccine | Timing |
|---|---|---|
| Newborn calf (0–24 hr) | Colostrum from vaccinated dam | Within 6 hours |
| 1–2 months | Intranasal respiratory (BRSV, IBR, PI3) | Early immunity while maternal antibodies decline |
| 3–4 months | 7-way Clostridial + Respiratory 5-way | Primary vaccination |
| 5–6 months | Booster + Brucellosis (heifers) | 4–12 months for Bang's |
| Pre-breeding heifers | Respiratory 5-way + Vibrio + Lepto 5-way | 30 days pre-breeding |
| Dry cow (60 days pre-calving) | Scours vaccine + J-5 (mastitis) + Respiratory booster | Dry-off period |
| Lactating cows — annual | Respiratory 5-way + Vibrio/Lepto | At herd health visit |
Herd Bull Vaccination
Bulls are often overlooked in vaccination programs — a costly oversight, because a bull carrying reproductive disease can spread it through the entire cow herd in one breeding season. Every bull should be vaccinated 30–60 days before turnout, every year, without exception.
- Respiratory 5-way — IBR, BVD, PI3, BRSV, Mannheimia
- Vibrio + Lepto 5-way — critical for reproductive protection
- Trichomoniasis — required in endemic areas (Texas, California, Nevada, some others)
- 7-way Clostridial — bulls die of blackleg too, especially young bulls on lush pasture
- Anaplasmosis — in endemic Southeast and Gulf Coast regions
Replacement Heifer Vaccination
Replacement heifers get the most vaccine attention on any operation, and rightfully so — they're the future of the herd. The heifer vaccine sequence has three critical windows:
- 4–12 months: Brucellosis vaccination (state-mandated in most states; can only be done by an accredited veterinarian; heifer is tattooed and permanently identified)
- 30 days pre-breeding: Full pre-breeding cocktail — respiratory 5-way, vibrio, lepto 5-way, scours vaccine
- 60 days pre-calving: Scours booster to concentrate antibodies in colostrum for the incoming calf
Handling & Injection Technique
Vaccine efficacy depends on more than choosing the right product — how you handle and inject the vaccine matters. Beef Quality Assurance (BQA) certification covers this in detail; the highlights below cover what every producer should know.
Storage and handling
- Refrigerate at 35–45°F from the moment you purchase
- Never freeze — a frozen vaccine is a dead vaccine
- Never expose to direct sunlight or heat during use
- Rehydrate MLV vaccines only when you're ready to use them; discard within 1 hour of mixing
- Use a clean, dedicated syringe for each vaccine (never mix products in the same syringe)
Injection sites (BQA standard)
All injections should be given in the neck — never in the rump, hip, or top-butt where the meat has value. Both subcutaneous (SC) and intramuscular (IM) injections belong in the triangle of muscle in front of the shoulder.
Mixing an MLV with a killed vaccine in the same syringe destroys the live product. Using disinfectants on syringes kills MLV. Recycling needles between animals spreads BVD and anaplasmosis. Vaccinating stressed, dehydrated, or sick animals produces poor immunity. Change needles every 10–15 animals, and never use a bent, dull, or contaminated needle.

Cost of Vaccination
Vaccination is one of the highest-ROI investments on any cattle operation. Typical 2027 cost per head:
| Animal Class | Vaccine Cost/Year | Labor | Total per Head |
|---|---|---|---|
| Mature beef cow | $8–$15 | $5–$8 | $13–$23 |
| Herd bull | $12–$22 | $5–$8 | $17–$30 |
| Replacement heifer (first year) | $18–$30 | $8–$12 | $26–$42 |
| Beef calf (birth to weaning) | $8–$18 | $5–$10 | $13–$28 |
| Dairy cow (annual) | $18–$32 | $4–$6 | $22–$38 |
Compare that to the cost of a single BRD case ($90–$230), a scours outbreak ($200+ per calf lost), or a full reproductive disease outbreak ($800–$1,200 per open cow) — and vaccination pays for itself many times over.
Frequently Asked Questions
What vaccines do cattle need annually?
Mature beef and dairy cattle need annual boosters of the core respiratory viruses (IBR, BVD, PI3, BRSV), leptospirosis 5-way, and vibriosis. Cows also need a scours vaccine 60–90 days pre-calving. Timing is 30–60 days before breeding season for reproductive protection.
When should calves be vaccinated?
Calves receive their first round of 7-way clostridial and respiratory 5-way at branding (2–4 months). A booster is given 3–6 weeks later, then a pre-weaning vaccination 45–60 days before weaning. Heifers being retained receive brucellosis vaccination between 4 and 12 months.
How much does it cost to vaccinate a cow?
Core annual vaccinations cost roughly $8–$15 per mature cow. Total per-cow vaccination cost including labor is typically $15–$25 per year — one of the highest-ROI expenses in cattle.
Can I vaccinate pregnant cows?
Yes, but MLV vaccines can cause abortion in pregnant cows unless they were previously vaccinated with the same MLV product. Killed vaccines are safe throughout pregnancy but require two doses initially. Always read the label and consult your veterinarian.
How long does a cattle vaccination last?
Most cattle vaccines provide 6–12 months of protection, which is why annual boosters are standard. MLV vaccines generally give longer, stronger immunity than killed vaccines.
