Primary Outcome Measures :
  1. Percentage of Participants With Pre-specified Local Reactions [ Time Frame: Days 1 through 14 ]
    Local reactions were collected by the participant using an electronic diary. Redness and swelling scaled as any(present); mild(2.5-5.0 centimeters[cm]); moderate(5.1-10.0 cm); severe(>10.0cm). Pain as any(present); mild(present, no interference with activity); moderate(present, some interference with activity); severe(present, prevents daily activity). Limitation of arm movement as any(present); mild(present, could move arm above head); moderate(could move arm above shoulder but not above head); severe(could not move arm above shoulder). Participants may be represented in more than 1 category.

  2. Percentage of Participants With Pre-specified Systemic Events [ Time Frame: Days 1 through 14 ]
    Systemic events were collected by participant using electronic diary. Fatigue,headache,new/aggravated generalized muscle pain,new/aggravated generalized joint pain: any, mild(no interference with activity), moderate(some interference with activity), severe(prevents routine daily activity). Fever(>=38 degrees Celsius[C]), chills, rash, vomiting(mild:1-2 times daily; moderate:>2 times daily; severe:prevents daily activity) decreased appetite & diarrhea(mild:2-3 loose stools/day; moderate:4-5 loose stools/day; severe:>=6 loose stools/day) reported. Participants may be represented in >1 category.

  3. Percentage of Participants Taking Pain or Antipyretic Medication [ Time Frame: Days 1 through 14 ]
    Use of pain or antipyretic medication was collected by the participants using an electronic diary.
