Evaluation of the Immune Responses of GSK Biologicals' HPV Vaccine Following Manufacturing Process Adaptation.

Study Overview
=================
Brief Summary
-----------------
Human papillomavirus infection has clearly been recognized as the cause of cervical cancer. Indeed, the infection of the cervix by certain oncogenic types of HPV, if not cleared , can lead over time to cervical cancer in women . This study will compare the immune response induced by different lots of the HPV-16/18 L1/AS04 vaccine, following adjustments to the manufacturing process.
