Clinical Trial for Measles - Rubella Combined Vaccine (MRVAC) Produced by POLYVAC (Phase III)
Study Details
Study Description
Brief Summary
The study is conducted to evaluate the safety and Immunogenicity of Measles-Rubella combined vaccine MRVAC produced by POLYVAC (phase 3) on Vietnamese volunteers and to demonstrate non-inferiority on the immunogenicity of MRVAC in comparison to MR vaccine produced by Serum Institute, India.

Phase 3 |
Detailed Description
A phase III, Randomized, control study to compare the immunogenicity and safety of MRVAC vaccine produced by POLYVAC with MR vaccine licensed in Vietnam produced by Serum Institute, India.
- Evaluate the safety of MRVAC produced by POLYVAC on Healthy Vietnamese volunteers from 1
- 45 years old.
Evaluate the safety by the ratio of participants having following symptom/signs:
-
The ratio of immediate adverse events (local adverse events and systemic adverse events), within 30 minutes after vaccination.
-
The ratio of participants having local and systemic adverse events (including unexpected adverse events) occur within 28 days after vaccination.
-
The ratio of serious adverse events (SAEs) occur from day 0 to day 28 after vaccination. (SAEs).
- Evaluate the immunogenicity of MRVAC produced by POLYVAC on the healthy volunteers from 1 - 45 years.
-
The rate of sero-conversion;
-
GMT (Geomatric mean Antibody titer) after vaccination.
- Comparison the safety and immunogenicity between MRVAC and control vaccine.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Trial arm (MRVAC) Measles and Rubella combined vaccine (lyophilized) MRVAC produced by POLYVAC is live attenuated measles vaccine. Each vial of 10 doses of measles-rubella combined vaccine is reconstituted with 5.5 mL of water for injection. Each single dose 0.5 mL contains the following components: Live, attenuated strain AIK-C measles virus not less than 1000 PFU Live, attenuated strain Takahashi rubella virus not less than 1000 PFU Subcutaneous injection |
Biological: Trial arm (MRVAC)
Volunteers from 1-45 years old will be injected only one dose of MRVAC vaccine
|
| Active Comparator: Control arm Measles and Rubella combined vaccine produce by Serum Institute, India (lyophilized) is live attenuated Measles and Rubella vaccines being used in the Vietnam expanded immunization program was used as control arm. Subcutaneous injection |
Biological: Control arm
Volunteers from 1-45 years old will be injected only one dose of MRVAC vaccine

Outcome Measures
Primary Outcome Measures
- Adverse events [During 30 minutes and 28 days after only one dose vaccination]

Secondary Outcome Measures
- Antibody seroconversion [42 to 56 days after only one dose vaccination .]
Positive seroconversion rates of Measles and Rubella neutralization antibody
- Geo-mean antibody titer [Before vaccination and after 42 to 56 days vaccination only one dose]
Geo-mean antibody titer of both trial arm and control arm
- Serious adverse event (SAE) [During 30 minutes and 28 days after vaccination only one dose]
Number of cases occur SAEs
