Hide Outcome Measure 10| Measure Type | Primary |
|---|---|
| Measure Title | Participants With 1 or More Systemic Adverse Experience |
| Measure Description | Systemic adverse experiences are unfavorable or unintended changes in the body after getting study vaccine. They are collected the first 14 days after receipt of dose 1 of hepatitis A vaccine (VAQTA™) (Days 1 to 14) within the 6 week study period. |
| Time Frame | 6 weeks post dose 1 |
| Safety Issue | Yes |
| Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate. |
|---|
| Includes all participants who provided safety follow-up after receipt of Dose 1 of VAQTA™ (hepatitis A vaccine) |
