Human papillomavirus (HPV), the most common sexually transmitted virus, and its associated diseases continue to cause significant morbidity and mortality in over 600 million infected individuals. Major progress has been made with preventative vaccines, and clinical data have emerged regarding the efficacy and cross-reactivity of the two FDA approved L1 virus like particle (VLP)-based vaccines. However, the cost of the approved vaccines currently limits their widespread use in developing countries which carry the greatest burden of HPV-associated diseases. Furthermore, the licensed preventive HPV vaccines only contain two high-risk types of HPV (HPV-16 and HPV-18) which can protect only up to 75 % of all cervical cancers. Thus, second generation preventative vaccine candidates hope to address the issues of cost and broaden protection through the use of more multivalent L1-VLPs, vaccine formulations, or alternative antigens such as L1 capsomers, L2 capsid proteins, and chimeric VLPs. Preventative vaccines are crucial to controlling the transmission of HPV, but there are already hundreds of millions of infected individuals who have HPV-associated lesions that are silently progressing toward malignancy. This raises the need for therapeutic HPV vaccines that can trigger T cell killing of established HPV lesions, including HPV-transformed tumor cells. In order to stimulate such antitumor immune responses, therapeutic vaccine candidates deliver HPV antigens in vivo by employing various bacterial, viral, protein, peptide, dendritic cell, and DNA-based vectors. This book chapter will review the commercially available preventive vaccines, present second generation candidates, and discuss the progress of developing therapeutic HPV vaccines.
