Scientific title | Randomised, Double-blinded, Placebo-controlled Clinical Trial of Pandemic Influenza Inactive Vaccine on Healthy Subjects |
Study acronym | RDPCTPIIVHS |
Study objectives | An inactivated monovalent A/H5N1 (influenza A virus) whole-virion, aluminum hydroxide adjuvated influenza vaccine will be safe and immunogenic in humans. |
Ethics approval(s) | Ethics approval gained from the ethical review committee of China Japan Friendship Hospital dated on 12 December 2005 (reference: 2005NO[37]Total[99]). |
Health condition(s) or problem(s) studied | Pandemic influenza |
Intervention | The trial is divided into four dosage groups and processed from low dosage vaccine to high dosage vaccine: 1. Group A: 30 subjects will be randomly injected with vaccines among which 24 subjects will be injected with the trial vaccine (1.25 µg) antigen and the other six subjects will be randomised into a placebo group. All subjects will be observed for 30 minutes for immediate reactions. Local reactions and systemic reactions were then observed at six, 24, 48 and 72 hours. The second dose will be injected 28 days after the first dose. The dosage, injection and observation method are the same as the first one. Subjects will be followed up for 210 days. Serum will be collected before the injection and then at 14, 28, 42, 56, 210 days after injection. The serums will be tested by the Haemagglutination-Inhibition (HI) assay. 2. Group B: 72 hours after the injection of Group A, when the safety of the vaccine is confirmed, 30 subjects will be randomly injected with vaccines, among them, 24 subjects will receive the trial vaccine (2.5 µg) and the other six subjects will be receive the control. The methods of safety observation and blood collection are as same as Group A. 3. Group C: 72 hours after the injection of Group B, when the safety of vaccine is confirmed, 30 subjects will be randomly injected with the vaccine. In the same way, 24 subjects will receive the trial vaccine (5.0 µg) and the other six subjects will receive the control. The methods of safety observation and blood collection are as same as Group A. 4. Group D: 72 hours after injection for the Group C, when the safety of vaccine is confirmed, 30 subjects will be randomly injected with vaccines. Among them, 24 subjects will receive the trial vaccine (10.0 µg) and the other six subjects will receive the control. The methods of safety observation and blood collection are as same as Group A. Trial vaccine is designed 0.5 ml per dose. The administration regimen is designed as a two dose schedule, which are given at day zero and day 28. |
