A pig vaccination schedule is a planned timeline of immunizations given at specific life stages to protect against the diseases most likely to affect a herd in a given region. There’s no single universal schedule — the right one depends on local disease pressure, herd purpose (breeding versus finishing), and veterinary guidance — but most farms build their schedule around a common set of core vaccines and predictable timing windows.

Why a Structured Schedule Matters

• Timing affects effectiveness. Many vaccines require a specific age window and sometimes a booster dose to provide full protection.
• Consistency protects the whole herd. A schedule followed for every animal, not just some, prevents gaps that a disease can exploit.
• Documentation supports market access. Many buyers and processors require proof of vaccination history before purchase.

Core Vaccines by Life Stage

Piglets (Pre-Weaning)

Early vaccinations often target diseases like Mycoplasma and circovirus, typically administered in the first few weeks of life alongside iron supplementation.

Weaners and Growers

This stage often includes protection against respiratory diseases such as PRRS and swine influenza, timed to bridge the gap as maternal antibodies decline.

Breeding Sows and Gilts

Vaccination schedules for breeding animals typically focus on reproductive diseases, timed relative to breeding cycles to maximize protection for both the sow and her litter.

Boars

Breeding boars generally follow a schedule similar to sows, with attention to any diseases that could be transmitted during breeding.

Building a Vaccination Schedule That Fits Your Farm

1. Start with a veterinary consultation. Regional disease risk varies, so a schedule copied from another region may miss locally relevant threats.
2. Map vaccines to specific ages or events. Tie each vaccine to a clear trigger — birth, weaning, breeding — rather than a vague timeframe.
3. Account for booster doses. Many vaccines require a second dose weeks after the first to reach full effectiveness.
4. Build in flexibility. Leave room to add vaccines in response to a new regional outbreak or changing herd composition.
5. Review annually. Revisit the schedule with your vet at least once a year, and sooner if local disease conditions change.

Record-Keeping Best Practices

• Log the vaccine name, batch number, date, and animal ID for every dose given
• Track booster due dates separately so they aren’t missed during busy periods
• Keep records accessible for buyers, processors, or health inspections
• Review records regularly to confirm no animals or groups were missed

Frequently Asked Questions

Who should design a pig vaccination schedule?

A veterinarian familiar with regional disease pressure should be involved in designing or reviewing the schedule, since the right vaccines and timing vary significantly by location and herd type.

What happens if a booster dose is missed?

Protection may be incomplete, since many vaccines are designed as a two-dose series where the booster is what provides full, lasting immunity. A missed booster should be given as soon as possible and noted in records.

Do vaccines replace the need for biosecurity?

No. Vaccines reduce the severity or likelihood of specific diseases they target, but they don’t protect against every pathogen, which is why they work alongside — not instead of — biosecurity and health monitoring.

How should vaccination records be stored?

A simple, consistent log — digital or paper — that records date, vaccine, batch number, and animal or group ID is sufficient for most farms, as long as it’s kept up to date and easy to reference.
