Clinical Trial Summary

To evaluate the safety and immunogenicity of lyophilized human rabies vaccine (Vero cell) developed by Hualan Biological in healthy people aged 9 to 65 years with two different immunization schedules.

Description:

The trial to assess the rabies vaccine (Vero cells) in healthy group of 9 ~ 65 years old after inoculation, the first dose after 14 days and 14 days after inoculation 5 agent group turn antibody positive rate of bad effect on 5 agent in the control group; The safety profile, seroconversion rate, and geometric mean concentration of the four-dose vaccine were noninferior to those of the five-dose regimen at 14 days after the first dose. More people aged 9-65 in the first agent free after 7 days, 14 days and 14 days after inoculation, 5 patients and 5 doses in the control group, four patients and 5 doses group antibody positive rate, GMC and GMC growth multiples have differences. To evaluate whether the seroconversion rate of subjects in the 4-dose experimental group reached 100% 14 days after the whole course of vaccination.

Intervention

Biological:
• Control vaccine
A group of 652 subjects were vaccinated with the control vaccine at 0, 3, 7, 14 and 28 days (5 doses in total). Blood samples were collected from the subjects at 0, 7/14 and 35/42 days for antibody detection.
• Experimental vaccine
A total of 652 subjects received 5 doses of the vaccine at 0, 3, 7, 14 and 28 days. Blood samples were collected on 0, 7/14 and 35/42 days for antibody detection.

Primary	1956 subjects accept the observation of systemic adverse reactions according to Guidelines for grading standard of adverse reaction of clinical trial of vaccine used for prevention.	Fever, allergy, headache, fatigue, nausea and vomiting, diarrhea, muscle pain, arthralgia and so on were observed	Every needle 30 days after vaccination

Secondary	The immunogenicity was tested by immunofluorescence staining	The rabies virus antibody was detected by immunofluorescence focus method. The positive rate was defined as the serum antibody concentration =0.5IU/ml	5 agent group gathering subjects were 0, 7, 14, 42 days of blood samples
Secondary	The immunogenicity was tested by immunofluorescence staining	The rabies virus antibody was detected by immunofluorescence focus method. The positive rate was defined as the serum antibody concentration =0.5IU/ml	Blood samples were collected on day 0, 7, 14 and 35 in the 4-dose group
