Measure Type Secondary
Measure Title Number of Participants Age 18 to 64 Years With 4-fold or Greater Hemagglutination Inhibition Assay (HAI) Antibody Titer Increases Against the Influenza H1N1 2009 Virus 21 Days Following the Second Dose of H1N1 Vaccine
Measure Description Blood was collected from participants for testing in the HAI assay with Influenza H1N1 2009 virus as the assay antigen. 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 Day 21 post second H1N1 vaccination titer was 1:40 or greater, or the Day 0 titer was greater than or equal to 1:10 and the Day 21 titer was an increase by 4-fold or more. Day 21 post second H1N1 vaccination is Study Day 63 for Group 4, and is Study Day 42 for all other groups.
Time Frame Day 0 prior to vaccination and 21 days after the second H1N1 vaccination  
Safety Issue No  

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 both H1N1 vaccinations and from whom blood was collected at the timepoint, all within 4 days of the window, are included. Eight participants were excluded due to eligibility deviations, vaccine administration error or other protocol deviations. Analyses are as treated. This outcome restricts to age stratum.
