EVALUATION OF THE LEVEL RESIDUAL H5N1 ANTIBODY RESULTS AND EPIDEMIOLOGICAL CHARACTERISTICS INVOLVED ON THE VOLUNTEER GROUP IN NHA TRANG

Tóm tắt

We conducted descriptive longitudinal follow-up and uncontrolled studies
performed on 185 subjects who received 2 doses of 15µg IVACFLU-A / H5N1
vaccine 21 days apart to determine persistent of antibody-H5N1 and some
Epidemiological characteristics involved, the results showed that: 18 months
after IVACFLU-A/H5N1 vaccination, the rate of antibody protection (titre ≥1/40)
still reached 61.6%; GMTs of the injection group reached 49.2. No statically
differences on age, gender and epidemiological characteristics related persistent of
anti-H5N1 antibody after vaccination. The research is still ongoing until 36
months after vaccination.
