Abstract
Locally prepared aluminium hydroxide gel and oil adjuvant infectious coryza vaccines were stored at 4°C and at room temperature for 27 months after preparation. The potency of these vaccines was determined by immunization of chicken at different periods of storage. The immunizing power of aluminium hydroxide gel and oil adjuvant vaccines stored at room temprature decreased gradually after 2 months. At the same time, the potency of the same vaccines stored at 4°C was still protective till 12 months of storage for aluminium hydroxide gel vaccine and two years for oil adjuvant vaccine.
