How to store chicken vaccines? Practical storage experience shared

Nowadays, many specialized chicken farmers and chicken farms buy vaccines from manufacturers or veterinary departments to vaccinate their chickens for disease prevention, and this practice should be encouraged and vigorously promoted. However, many breeders or chicken farms mistakenly believe during the transportation and storage of vaccines that all vaccines should be stored in a low-temperature environment, and that the lower the temperature, the better. Therefore, regardless of the type of vaccine, they store all vaccines in ice bottles or refrigerators below zero degrees (freezing), which is not entirely correct. Because chicken vaccines are diverse, such as the commonly used vaccines including Newcastle disease strain I vaccine, Newcastle disease strain II attenuated vaccine, Newcastle disease strain III vaccine, etc.; commonly used bacterins include fowl cholera aluminum hydroxide bacterin, infectious coryza vaccine, E. coli vaccine, etc. These different vaccines have different temperature requirements during transportation and storage. The first 3 vaccines are all live attenuated vaccines, and they must be stored under zero-degree (freezing) low-temperature conditions, avoiding high temperatures and sunlight exposure, otherwise they will become ineffective. However, the latter 3 vaccines such as fowl cholera aluminum hydroxide bacterin cannot be stored under zero-degree (freezing) low-temperature conditions; their most suitable storage temperature is 2°C to 14°C. If the temperature is too high, the storage period will be shortened, but they must not freeze, as freezing can destroy their properties and cause them to lose their immune characteristics. Therefore, the temperatures for transporting and storing different chicken vaccines should be differentiated, and they should be stored according to the temperature requirements of the vaccines.
