Primary Outcome Measures :
  1. Frequency of adverse events up to seven days after immunization [ Time Frame: Seven days after each immunization ]
    Frequency of adverse reaction in the seven days following each immunization per age group

  2. Frequency of adverse events up to 21 days after immunization [ Time Frame: 21 days after each immunization ]
    Frequency of adverse reaction in the 21 days following each immunization per age group

  3. The proportion of volunteers with increased levels of the immune response of specific neutralizing antibody titers in ELISA following the vaccination, compared with a placebo [ Time Frame: at days 0, 21, 27, 42, 90, 180 ]
    The proportion of volunteers with changed levels of the immune response of specific neutralizing antibody titers in ELISA greater than ≥ 4 times compared with a placebo.


Secondary Outcome Measures :
  1. Incidence of serious adverse events during the study [ Time Frame: throughout the study, an average of 42 days ]
    Incidence of serious adverse events during the study.


Other Outcome Measures:
  1. Cell-mediated immune profile [ Time Frame: at days 0, 7, 21, 42 ]
    Cellular immunity will be assessed by reliable (more than 2 standard deviations from the mean pre-vaccination level) increases in post-vaccination level (%) of CD4 + and CD8 + T-cells.
