Complete Cattle Vaccination Schedule 2026: Dairy, Beef & Calves

Cattle Vaccination Schedule

Why Your Cattle Vaccination Schedule Is Your Most Valuable Investment

Vaccination is the single most cost-effective disease control tool available to cattle farmers worldwide. A single outbreak of Foot and Mouth Disease (FMD) can result in mass culling, multi-year trade bans, and farm losses exceeding hundreds of thousands of dollars. A clostridial disease outbreak (blackleg, pulpy kidney) can kill multiple animals in 24 hours — animals that could have been protected for a few dollars each per year.

Despite this, underperforming vaccination programmes remain one of the most common problems identified in cattle herd health reviews. The most common failures are: starting too late, missing booster timing, incorrect storage (cold chain failure), and not covering all animals in the herd. This guide gives you a complete, practical vaccination schedule for 2025, tailored to dairy cattle, beef cattle, and calves.

Core Vaccines Every Cattle Herd Needs

Regardless of your location, production system, or herd size, these vaccine groups cover the most critical global cattle diseases. Regional additions are listed below.

Beef Cattle Vaccination Schedule

Calf Vaccination Schedule — Building Immunity From Day One

Newborn to 3 Months

Newborn calves depend entirely on maternal antibodies (immunoglobulins) delivered through colostrum in the first 6 hours of life. This is your first and most critical immune intervention — not a vaccine, but essential for all vaccine programmes to work properly. Calves that miss quality colostrum in the first 6 hours have massively impaired immune response to all subsequent vaccinations.

• 0–6 hours: Ensure colostrum intake — minimum 3 litres for dairy calves, 2 litres for beef calves
• 3–4 weeks: Intranasal BRD vaccine (RSV, Pi3) — can be given from 10 days in high-risk herds
• 3–4 weeks: IBR intranasal vaccine if herd is IBR-positive

2–4 Months — Primary Vaccination Course

• 8–12 weeks: First clostridial vaccine (blackleg, pulpy kidney). Give 2 doses 4 weeks apart
• 8–12 weeks: First BVD vaccination if not covered by maternal colostrum immunity
• FMD (endemic regions): follow national schedule — often from 4 months

First Booster — 12–16 Weeks

• Second dose of all primary vaccines given 4 weeks after first dose
• Annual boosters align with herd schedule from 12 months onwards

Frequently Asked Questions

How long after vaccination does a cow develop immunity?

Most injectable vaccines provide protective immunity within 2–3 weeks of the final primary dose (or booster). For intranasal BRD vaccines, partial immunity develops within 3–5 days — making them useful for pre-housing use in beef cattle where housing date may coincide with disease risk. Plan your vaccination programme so that immunity is established before the peak disease risk period in your herd.

What happens if I miss a booster?

Missing a booster — particularly for clostridial diseases or leptospirosis — can result in waning immunity and return to susceptibility. For most vaccines, if a booster is overdue by more than 2–4 weeks, your vet may recommend restarting the two-dose primary course rather than continuing as a single booster. Do not simply give the booster late without veterinary advice — vaccination response may be suboptimal.

Can I vaccinate a pregnant cow?

Many cattle vaccines are safe in pregnancy and are specifically designed for pre-calving use (particularly clostridial, leptospirosis, and E. coli/rotavirus vaccines). However, some modified live virus (MLV) vaccines for BVD and IBR must NEVER be given to pregnant cattle as they can cause abortion or foetal deformity. Always read the datasheet and consult your vet before vaccinating pregnant animals.
