Vaccination Programs

Many factors must be considered in determining the vaccination program for a particular farm or poultry operation. To be fully effective, the vaccine must be administered to healthy receptive birds held in proper environment under good management. In addition, the response may be modified by the age of the birds and their immune status. Seldom does 1 vaccination under field conditions produce complete protection for all individuals in a given flock. The amount of protection required will vary with the type of operation and the degree of exposure that a flock is likely to encounter.

Drinking Water Administration

FOR CHICKENS TWO WEEKS OF AGE OR OLDER

1. Do not use any disinfectants in the drinking water for 48 hours before vaccinating and 24 hours after vaccination.
2. Withhold water from the chickens until they are thirsty.
3. Calculate the water volume needed so the vaccine will be consumed in approximately 2 hours.
4. Optional: as an aid in preserving the virus, add a vaccine stabilizer to the stock solution or to the tank containing clean, cool, nonchlorinated water. Agitate thoroughly. Follow the manufacturer’s rate of administrations and wait time.
5. Add rehydrated vaccine from vial to the water and mix thoroughly.
6. Turn on tank valve or automatic dosing system.
7. Provide as sole source of drinking water until all vaccine-water solution has been consumed.

Coarse Spray Administration

FOR CHICKENS ONE DAY OF AGE OR OLDER
Calculate the water volume needed. For example, a machine which dispenses 21 ml to a box of 100 chickens – total volume for 10,000 doses is 2,100 ml of non-chlorinated water. For coarse spray in chicken houses, follow manufacturer’s direction for the particular spray machine. Add rehydrated vaccine and mix thoroughly.
