A study on immune response of black chicken (Gallus gallus domesticus brisson) vaccinatedby H5N1 Re-6 and Navet-Vifluvac vaccines in Tien Giang province was conducted throughHemagglutination Inhibition test using experimental black chicken serum samples. The studiedresult showed that the protective rate of passive antibodies in one-day old chicken in thetreatment 1 (H5N1 Re-6 vaccine) and the treatment 2 (Navet-Vifluvac) was 60% and 65%respectively. The protective rate of passive antibodies of the chickens at 14 days old chicken inthe treatment 1 and treatment 2 was 40% and 50% respectively.The protective rate of the black chickens after one month vaccinating H5N1 Re-6 vaccine in the treatment 1 for the chickens at 30 days old, 60 days old, 90 days old , 120 days old, 150days old and 180 days old was 16%, 65%, 85%, 85%, 75% and 65% respectively. Similarly inthe treatment 2, after one month vaccinating Navet-Vifluvac vaccine, the protective rate of thechickens at 30 days old, 60 days old, 90 days old, 120 days old, 150 days old and 180 days oldwas 25%, 85%, 95%, 85%, 80% and 55% respectively.The studied results showed that the ability of chickens in creating immune response aftervaccinating H5N1 Re-6 vaccine was faster and higher than that of Navet-Vifluvac vaccine.Kết quả khảo sát đáp ứng miễn dịch đối với hai loại vacxin cúm A H5N1 trên gà ác (Gallus gallusdomesticus brisson) tại tỉnh Tiền Giang bằng phản ứng ức chế ngưng kết hồng cầu (HI) cho thấy:Kháng thể thụ động đối với virus cúm gia cầm của gà ác ở nghiệm thức 1 (vacxin H5N1 Re-6) là60% đối với gà ở 1 ngày tuổi và 40% ở 14 ngày tuổi
