Treatment and study plan

Primary outcomes

  1. Incidence Rate of Syncope

    Time frame: On day of each vaccination

    Syncope was defined as the presence of a syncope diagnosis code in the emergency room or hospital setting in the vaccination risk period or in the post-vaccination self-comparison period. These codes could have represented a new event, a pre-existing event, a prior history of the event, a "rule out" diagnosis, miscoding, or a misdiagnosis. Consistent with the study's design, diagnosis codes for general safety analyses were not confirmed in this study.

  2. Incidence Rate of Cellulitis

    Time frame: Within 14 days and within 60 days immediately after each vaccination

    Cellulitis was defined as the presence of a cellulitis or abscess diagnosis code in the emergency room or hospital setting in the vaccination risk period or in the post-vaccination self-comparison period. These codes could have represented a new event, a pre-existing event, a prior history of the event, a "rule out" diagnosis, miscoding, or a misdiagnosis. Consistent with the study's design, diagnosis codes for general safety analyses were not confirmed in this study.

Secondary outcomes

  1. Number of Congenital Anomalies Among Females Who Received Gardasil During Pregnancy

    Time frame: First dose of Gardasil in pregnancy up to 6 months after birth

    Pregnancy exposure was defined as receipt of Gardasil at any time from 1 month prior to conception through end of pregnancy.

  2. Number of Miscarriages Among Females Who Received Gardasil During Pregnancy

    Time frame: First dose of Gardasil in pregnancy up to pregnancy resolution

    Pregnancy exposure was defined as receipt of Gardasil at any time from 1 month prior to conception through end of pregnancy.

  3. Number of Cases of New Onset Autoimmune Conditions in Females Receiving at Least One Dose of Gardasil

    Time frame: within 6 months immediately after each vaccination

    Autoimmune cases were defined as newly diagnosed cases within 6 months after any

    dose of Gardasil, as confirmed by medical record review by panels of physicians specializing in the 16 autoimmune conditions of interest.
