Brief Summary
This is a community intervention effectiveness study in female school students in Thailand. The study objectives are:
- 1.To demonstrate HPV vaccine effectiveness of Single Dose (SD) by a reduction in vaccine-type HPV prevalence (HPV 16 and HPV 18) at Year 2 and Year 4 post vaccination compared to unvaccinated same grade female students
- 2.To demonstrate that HPV vaccine effectiveness of SD and two-dose (2D) regimens are similar by comparing reductions in vaccine type prevalence at Year 2 and Year 4 post vaccination compared with the baseline surveys in the two provinces
