- Primary Outcome Measures
Name Time Method It is a study to acess vaccine safety, reported in forms and diaries of adverse events distributed to subjects and occurred within 30 days after each dose of vaccine, through frequency tables and intensity of adverse events - local, systemic and not expected.;Among the 30 vaccinated subjects, 12 (40%) had at least one adverse event requested after the first dose and 6 (20%) after the second dose. No serious adverse events were recorded. Of the 18 laboratory results to increase postvaccination degree , compared to pre- vaccination , 4 were classified as grade 3 and one as grade 4 without clinical significance.
- Secondary Outcome Measures
Name Time Method The immunogenicity of the vaccine under study will be analysed by the geometric mean titers of antibodies pre and post vaccination evaluation that will be obtained by enzyme-linked immunosorbent assay (ELISA) with blood samples from the participants before (baseline) and after each dose of vaccine administered .;The geometric mean titers (GMT) for measles and rubella increased after the 1st and 2nd doses , compared to pre-vaccination titers. The ratio of measles TMG post/pre 1st dose was about 3 times, and rubella, 1.5. The ratio GMT measles post 2nd dose/pre 1st dose was 3.1 and 1.5 rubella again.
