Measure Type Secondary
Measure Title Number of Participants Age 6 to Less Than 36 Months With 4-fold or Greater Hemagglutination Inhibition Assay (HAI) Antibody Titer Increases Against the Virus Strains in the 2009-2010 Trivalent Influenza Vaccine (TIV) 21 Days Following the Last Vaccination
Measure Description Blood was collected from participants for testing in the HAI assay against each strain in the 2009-2010 trivalent influenza vaccine. A participant met the threshold of a 4-fold rise in titer if the Day 0 titer was less than 1:10 (the assay's lowest level of detection) and the titer at 21 days after last vaccination was 1:40 or greater, or the Day 0 titer was greater than or equal to 1:10 and the titer at 21 days after last vaccination was an increase by 4-fold or more. Day 21 after last vaccination was study Day 63 for Groups 1 and 4, and study Day 42 for Groups 2 and 3.

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.
Participants who received all vaccinations and from whom blood was collected at the timepoint, all within 4 days of the window, are included. Two participants were excluded due to receipt of non-study vaccines and one due to Influenza-like illness. Analyses are as treated. This outcome restricts to age stratum.

  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.
