| Abstract | ||||
| Poultry vaccines should have a specific storage temperature range to ensure their effectiveness. It is still unclear in Egypt, nevertheless, if these temperature ranges are rigidly specified as handling conditions or as recommendations. Large endemic and epidemic outbreaks of poultry illnesses frequently threaten Egypt's sizable conventional and exotic chicken industries. Although it is assumed in vaccine logistics that most of these safety measures are followed, handling vaccines within the specified temperature range is frequently not feasible. It is challenging to keep vaccines within a designated storage temperature range when they are being transported, according to earlier research. This is an issue not just in nations with weak cold chains but also in nations and areas with strong cold chains. Specifically, the chance of unintentionally being exposed to below-freezing conditions has been disregarded globally. This is a serious concern for vaccination consumers as well as the veterinarians who oversee vaccine usage. Because they cannot ensure the quality of vaccines whose storage temperature may have been beyond the prescribed range, veterinarians should advise consumers not to vaccinate birds with these vaccines. Additionally, the user is directly harmed in the uncommon case that a handling error impairs the quality of the vaccination. | ||||
