Measure Type Primary
Measure Title Number of Participants Age 36 Months to 9 Years Reporting Solicited Quantitative Local Reactions After the Second H1N1 Vaccination
Measure Description Participants or their parents/guardians maintained a memory aid to record daily the occurrence of local reactions of swelling and redness for 8 days (Day 0-7) after vaccination. If the reaction was present, the maximum diameter was measured in millimeters (mm). Participants are counted if they reported experiencing the reaction with any measurement greater than 0 mm on any of the 8 days. Second H1N1 vaccination was given on Study Day 21 for Groups 1, 2 and 3, and on Study Day 42 for Group 4.
Time Frame Within 8 days (Day 0-7) post second H1N1 vaccination  

Population Description
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.
All participants receiving the second H1N1 vaccination are included in the safety cohort. Analyses are as treated. This outcome measure is restricted to protocol-defined age stratum.

Group 1: Day 0-H1N1; Day 21-H1N1; Day 42-TIV Participants received 15 mcg H1N1 Vaccine on Day 0; 15 mcg H1N1 Vaccine on Day 21, and Trivalent Influenza Vaccine (TIV) on Day 42
Group 2: Day 0-H1N1+TIV; Day 21-H1N1 Participants received 15 mcg H1N1 Vaccine + Trivalent Influenza Vaccine (TIV) on Day 0 and 15 mcg H1N1 Vaccine on Day 21
Group 3: Day 0-H1N1; Day 21-H1N1+TIV Participants received 15 mcg H1N1 Vaccine on Day 0 and 15 mcg H1N1 Vaccine + Trivalent Influenza Vaccine (TIV) on Day 21
Group 4: Day 0-TIV; Day 21-H1N1; Day 42-H1N1 Participants received Trivalent Influenza Vaccine (TIV) on Day 0; 15 mcg H1N1 Vaccine on Day 21, and 15 mcg H1N1 Vaccine on Day 42.

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Due to difficulties identifying children in the youngest age stratum who were previously primed, enrollment in this stratum was closed prior to meeting the planned number of participants.
