Percentage of Participants Who Reported a Lower Need to Practice Safe Sex Following HPV Vaccination and the Percentage of Participants That Reported a Higher Need to Practice Safe Sex Following HPV VaccinationWeek 48

Participants' perceptions for the need to practice safe sex following HPV vaccination was measured using a safer sexual behaviors subscale, which was comprised of the following five questions:

After getting vaccinated against HPV ...

1. You feel that condom use during sex is less necessary.

2. You feel it is still just as important to have as few sexual partners as possible.

3. You feel that it is less important to talk to your sex partners about safe sex.

4. You think it is still just as important to use a condom every time you have sex.

5. You will be less worried about having unprotected sex. Those who were categorized in the "lower need for safer sexual behaviors (NSSB)" group had a summary score that was less than the median and those in the "higher NSSB" group had a summary score that was equal to or higher than the median.

Adverse Events (AE) Reported Among Participants Who Were Randomized to the Telephone Response System (TRS) or Vaccine Report Card (VRC).Day 1 through Week 24

Rate of AEs is the total number of AEs divided by the total number of participants. The rate is not a percentage bur rather it could be above 1 or less than 1. This outcome measure looked at number of AEs reported, by grade; number of AEs \> Grade 3 identified; and number of AEs \> Grade 3 evaluated within 24 or 48 hours.
