Sheep and Goat Vaccination Schedule: A Practical Guide
Which vaccinations do sheep and goats need in Saudi Arabia and the Gulf, and when are the primary and booster doses due? A working schedule, common mistakes, and what to record for every dose.
Most sudden deaths in a barn are not bad luck. They are usually a disease with a well-known vaccine whose date was missed, or whose dose was given the wrong way. Vaccination is the cheapest insurance you will ever buy for a flock: a dose costs a fraction of one animal. This guide covers the core vaccinations for sheep and goats, when they are due, and how to turn "sometime next month" into a written schedule per head.
Important: the programme below is a general framework used by many breeders and vets. Your final programme is set by your own veterinarian and by the national campaigns of the Ministry of Environment, Water and Agriculture (or the competent authority in your country) — the diseases in circulation differ by region and by year.
Why vaccination fails for so many breeders
Before the schedule, three reasons an excellent vaccine does nothing:
- Heat. Most vaccines must stay between 2 and 8 °C. A vial left in a car for an hour in summer can lose its potency completely.
- The forgotten booster. Many vaccines need a primary dose followed by a booster 3–4 weeks later. Without the second, protection is weak and short-lived.
- Vaccinating a sick or stressed animal. An animal with diarrhoea or fever, or one that has just been transported, will not build good immunity. Vaccinate in cool conditions (early morning) and after the animal has settled.
Core vaccinations for sheep and goats
The table summarises the vaccinations that appear most often in regional programmes. Timings are approximate — follow what your vet writes and what the vaccine label states.
| Disease | Why it matters | Primary dose (typically) | Booster and repeat |
|---|---|---|---|
| Enterotoxaemia (clostridial) | Sudden death in well-grown lambs and kids, especially after a ration change | 6–8 weeks of age (earlier if the dam is unvaccinated) | Booster 3–4 weeks later, then annually; dams 4–6 weeks before lambing |
| PPR (peste des petits ruminants) | Highly contagious viral disease; national campaigns in many countries | From 3–4 months (maternal immunity interferes earlier) | Per the national programme; protection is long-lasting |
| Sheep and goat pox | Losses in skin, wool and weight; deaths in young stock | From 2–3 months | Annually, ahead of the season |
| Foot-and-mouth disease (FMD) | Trans-boundary disease, covered by periodic campaigns | Per campaign | Every 4–6 months in exposed areas |
| Pasteurellosis (pneumonia) | Deaths after transport, crowding and weather changes | On vet advice, usually before transport or the cold season | Annually or before the risk season |
| Brucellosis | Abortion in dams; transmissible to humans | Only under the competent authority's supervision | Per the national programme |
The table does not cover internal and external parasite control (worms, ticks, mange). That is not vaccination, but it belongs on the same calendar — and it should follow faecal testing and vet advice rather than blanket dosing, which breeds resistance.
The year as one cycle
Treat the production year as a single loop starting at mating:
- Two weeks before mating: body condition scoring, parasite control where needed, and any overdue vaccination for rams and ewes.
- 4–6 weeks before lambing: clostridial booster for the dams — the protection passes to the newborn through colostrum.
- At birth: colostrum within the first 6 hours. This is nature's vaccination and matters more than any later dose.
- 6–8 weeks: first doses for lambs and kids, booster 3–4 weeks later.
- 3–4 months: seasonal vaccinations for young stock (PPR, pox, per the programme).
- Before summer and before the cold: review FMD and pasteurella campaigns.
What to record with every dose
The difference between a breeder who loses money and one who does not is rarely the vaccine — it is the record. For every vaccination, write down:
- The animal's number (or the group's numbers). Never "all the sheep".
- Vaccine name, batch number and expiry date — invaluable if a particular batch turns out to be faulty.
- Dose, route (subcutaneous, intramuscular) and who gave it.
- The next due date. This single line is what prevents a missed booster.
- The withdrawal period, where one applies. Some products have a period during which meat or milk must not be sold. Write it next to the animal, not in your head.
In Throf, the vaccination programme does this for you: pick the vaccine and the group, see the monthly and weekly calendar, get an alert before the date, and have the withdrawal period written into each animal's file after every treatment.
Common mistakes you still see in barns
- One needle for dozens of animals: it spreads disease and damages the dose.
- Keeping an opened vial for next week: read the label — most are single-day use.
- Vaccinating new arrivals on the day they arrive: isolate for 3–4 weeks first, then bring them into the programme.
- Relying on memory above 30 head. That is exactly where the gaps start.
The short version
Vaccines are cheap, deaths are expensive, and the record is what connects the two. Start with a simple schedule for the three most important vaccinations in your area, fix the booster dates, and log every dose against an animal number. Over time you build a complete health history per head — useful at sale, at selection, and at every vet visit.
FAQ
Can pregnant ewes be vaccinated?
For some vaccines yes, and it is recommended: the clostridial booster 4–6 weeks before lambing protects the newborn through colostrum. Some live vaccines are not given to pregnant animals, so read the label and ask your vet.
The booster is two months overdue — what now?
In most cases the course is restarted (primary, then booster), because protection from a single primary dose fades quickly. Never double the dose to make up for the delay.
How many times a year should I vaccinate the flock?
It depends on the vaccine and the region: some are annual, others every 4–6 months in exposed areas (FMD, for example). What matters is that every head has a written calendar with its next date.
