Brief 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.

Detailed 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.

Interventions

BIOLOGICALControl 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.

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.

Design outcomes

Primary

MeasureTime frameDescription
1956 subjects accept the observation of local adverse reaction according to Guidelines for grading standard of adverse reaction of clinical trial of vaccine used for preventionEvery needle 30 days after vaccinationTenderness, pruritus, induration, redness, swelling and its degree of size and disturbance of body activity at the inoculation site
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.Every needle 30 days after vaccinationFever, allergy, headache, fatigue, nausea and vomiting, diarrhea, muscle pain, arthralgia and so on were observed

Secondary

MeasureTime frameDescription
The immunogenicity was tested by immunofluorescence staining5 agent group gathering subjects were 0, 7, 14, 42 days of blood samplesThe rabies virus antibody was detected by immunofluorescence focus method. The positive rate was defined as the serum antibody concentration ≥0.5IU/ml
