Coccidiosis Vaccine

Live Oocysts, Chicken Isolates

For vaccination of chickens against Coccidiosis as directed.


For vaccination of healthy chickens against coccidiosis via spray on feed during the first 3 days of age or by spray cabinet at one day of age, as directed below. This vaccine contains live oocysts of Eimeria tenella, E. mivati, E. acervulina, E. maxima, E. brunetti, E. hagani, E. necatrix, and E. praecox.

Using Medicated Feeds And Coccivac

COCCIVAC is not ordinarily recommended for use on chickens receiving a feed containing a coccidiostat or high levels of antibiotic. After vaccination, it may become necessary to use high levels of drugs for treatment of disease conditions other than coccidiosis. If such drugs, with coccidiostatic activity, are used during the first or second week after vaccination with COCCIVAC, revaccination with COCCIVAC is recommended.

Feed Spray Application

Recommended for vaccination of healthy chickens during first 3 days of age (preferably at first day).

1. Do not use any medicated drinking water or disinfectant 24 hours before and after vaccination or during vaccination.

2. Feed sprinkled on paper under the feed line increases the exposure of chicks to the vaccine.

3. Dilute each 1000 dose vial of Coccivac with 500 mL of clean water.

4. Mix well and place in clean garden type pressure sprayer.

5. Spray the diluted vaccine over the surface of the feed. Agitate the sprayer during administration.

6. For best results, the vaccine should be sprayed on all of the feed just prior to placement of the chicks.

7. Avoid wetting the feed. Proper application will only dampen the surface of the feed.

8. Allow the chicks sufficient time to ingest the oocysts on the feed before placing more feed in the pans or on the paper.

Spray Cabinet Administration

Recommended for vaccination of healthy chickens at one day of age.

1. Use diluted vaccine as directed for each coarse spray vaccinating machine.

When using a SPAH spray cabinet, we recommend diluting each 1000 doses of vaccine to 210 mL. Use non-chlorinated water.

2. Add the vaccine solution to pressure reservoir of the spray apparatus.


3. Prime and adjust the machine as indicated on the machine operating instructions.

4. Place boxes holding 100 chickens each on the conveyor belt or in machine. Activate the spray head.

5. Using a SPAH machine, each box of 100 chicks receives 21 mL of vaccine solution.

General Information

- Unhealthy chickens should not be vaccinated.

- Chickens may be started on paper, but it should be removed and chickens should be on litter by the 4th day after vaccination. Chickens must have access to their droppings as reinfection is required to give immunity.

- Chickens raised in batteries, or on wire, cannot be effectively vaccinated by COCCIVAC. Chickens started in batteries, or on wire can be effectively vaccinated if they are placed on litter not later than the 4th day after vaccination.

- Moisture is necessary for oocysts to sporulate. If litter conditions are extremely dry during the vaccination period, sprinkling or spraying the litter (to slightly damp) with water is recommended.

- If there is a noticeable reaction from COCCIVAC, it usually occurs between the 12th and 14th days after vaccination. Do not treat for coccidiosis unless mortality or severe morbidity is directly attributable to coccidiosis. When positive diagnosis is made, treat with sulfaquinoxaline, sulfamethazine or amprolium in the drinking water. Treatment for 48 hours using the manufacturers lowest recommended level will usually be adequate.

Coccivac-D Caution

- Do not vaccinate within 21 days before slaughter.

- Use entire contents of each vial when first opened.

- Store vaccine in refrigerator under 7°C (45°F). DO NOT FREEZE.

- This vaccine contains gentamicin as a preservative

- Burn container and all unused contents.

The capacity of this vaccine to produce satisfactory results depends on many factors, including but not limited to conditions of storage and handling by the user, administration of the vaccine, health and responsiveness of individual animals and degree of field exposure. Therefore, directions for use should be followed carefully.
