Placebo GroupPlaceboSubjects, 18 - 40 years, receiving two doses of placebo (saline solution) during Step 1 of the study and subjects, 50 - 70 years, receiving two doses of placebo (saline solution) during Step 2 of the study. Intramuscular injection should be done in the deltoid of the non-dominant arm. In case it is not possible to inject in the non dominant arm, an injection in the dominant arm may be performed.

Assessed solicited local symptoms are pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.

Number of Subjects With Any Solicited General Adverse Events (AEs)During a 7-day follow-up period (Day 60 to Day 66) after second dose.
