Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Solicited symptoms were collected for 3730 and 3740 subjects instead of the 3727 and 3739 subjects who were randomized in the study in the Cervarix and the Havrix groups, respectively. These 4 sujects received both vaccines and were included in the denominator of both arm based on the actual vaccine type administered.

Reporting Groups
  Description
Cervarix Group Subjects received 3 doses of Cervarix vaccine at study Months 0, 1 and 6. All the vaccine doses were administered intramuscularly in the deltoid region of the non-dominant arm.
Havrix Group Subjects received 3 doses of Havrix vaccine at study Months 0, 1 and 6. All the vaccine doses were administered intramuscularly in the deltoid region of the non-dominant arm.

Measure Type Secondary
Measure Title Number of Subjects Reporting Any and Grade 3 Solicited General Symptoms.
Measure Description Solicited general symptoms assessed were arthralgia, fatigue, gastrointestinal, headache, myalgia, rash, urticaria and fever (Fever = oral temperature equal to or above (≥) 37.5 degrees Celsius (°C)). Any = any solicited general symptom reported irrespective of intensity and relationship to vaccination. Grade 3 symptoms = symptoms that prevented normal everyday activities as assessed by inability to attend work or school and which necessitated the administration of corrective therapy.Grade 3 urticaria = urticaria distributed on at least 4 body areas. Grade 3 fever = oral temperature > 39.0°C.
Time Frame Within 60 minutes after vaccination  
Safety Issue No

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
The following analysis "occurence of histopathologically confirmed CIN2+ cases associated with HPV16 or HPV18 infection was not performed, in accordance with the Statistical Analysis Plan submitted to the FDA.
