HPV prophylactic vaccines: Second-generation or first-generation vaccines

Second-generation prophylactic HPV vaccines: successes and challenges.

The role of HPV as the causative factor in cervical cancer has led to the development of the HPV vaccines Gardasil and Cervarix. These vaccines effectively protect against two HPV types associated with 70% of cervical cancer cases. Despite this success, researchers continue to develop second-generation HPV vaccines to protect against more HPV types and allow increased uptake in developing count...

Prophylactic HPV vaccines.

The HPV L1 VLP vaccines are immensely important developments in public health and the benefits that they promise are immense, offering the opportunity to prevent, in the long term, 80% of cervical cancers, 60% of vulval cancers and 80% of anal cancers in women. In the short to medium term they will prevent at least 90% of genital warts and have a major impact on the incidence of high grade CIN,...

Prophylactic HPV Vaccines

Cervical cancer and its precursor intra-epithelial lesions are linked to infection by a subset of human papillomavirus (HPV) types, the so-called “high-risk” HPVs, the most prevalent being HPV16 and HPV18. Two prophylactic vaccines containing combinations of the major capsid protein (L1) of HPV16 and HPV18 have been shown to efficiently prevent infection by inducing capsid-specific neutralizing...

Chapter 17: Second generation HPV vaccines to prevent cervical cancer.

Prophylactic human papillomavirus (HPV) vaccines based on intramuscular injection of non-infectious L1 virus-like particles (VLPs) are undergoing intense clinical evaluation. As documented in preceding chapters of this monograph, clinical trials of these vaccines have demonstrated their safety and high efficacy at preventing type-specific persistent cervical HPV infection and the development of...
