Measure Type Secondary
Measure Title Number of Participants With a Serum Hemagglutination Inhibition Assay (HAI) Antibody Titer Greater Than or Equal to 40 Against the Novel Influenza H1N1 2009 Virus in the Maternal Blood at the Time of Delivery
Measure Description Blood was collected from participants at the time of delivery for testing in the HAI assay with Influenza H1N1 2009 virus as the assay antigen. Each sample was tested at least twice according to standard operating procedures and the result of each replicate reported. A participant is counted if the geometric mean of the replicate values was 1:40 or greater.
Time Frame At time of delivery

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.
Pregnant participants were included in the analyses if they had blood collected at delivery, with 1 participant excluded due to receipt of non-study vaccine. Participants were analyzed as treated.

Certain Agreements:  
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.


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
Although 200 pregnant and 100 non-pregnant subjects were targeted for enrollment, enrollment closed in May 2010 prior to reaching the target due to slow accrual.
