Trial of Two Versus Three Doses of Human Papillomavirus (HPV) Vaccine in India

The primary study hypothesis wasthat a two-dose human papillomavirus (HPV) vaccine regimen would offer similar immunogenicity and protection as that of a three-dose regimen to girls against persistent HPV infection and cervical neoplasia caused by HPV types included in the vaccine. The Government of India stopped vaccination in all the HPV vaccine trials in the country in April 2010 due to reasons not related to this study.
