[h=3]Abstract[/h] Context Adjuvants are compounds used in the preparation of inactive vaccines to enhance the immune response. Aluminum hydroxide (alum) is one of the first compounds approved by the Food and Drug Administration, which is used as adjuvants in vaccine products for humans. Montanide ISA 70 is an oil-emulsion adjuvant and is used in poultry inactive vaccines. Objective In this study, the effects of alum adjuvant on the efficiency and induction of immune response in inactive vaccines of Influenza and Newcastle are compared with those of ISA 70. Materials and methods Six groups of 7-d-old specific-pathogen-free chickens were inoculated with 0.3 ml of the prepared vaccines via the subcutaneous route in the neck. Immune response in each group after 7, 14, 21, 31, 41, and 45 d was evaluated using the technique of hemagglutination inhibition. Results The results were compared using SPSS software. Results showed that vaccines containing adjuvant ISA 70 depicted a higher increase in the immune response and adjuvant of 20% alum is similar to adjuvant of ISA 70 in boosting the immune system. There was no statistically significant difference between 10% and 20% alum, but these adjuvants are visibly different from ISA 70. Conclusion In conclusion, alum can be used as an easily accessible, harmless, and effective adjuvant; however, to increase the immune period using the inactive vaccines for poultry, more research would be necessary.
