Chapter 16: Prophylactic Human Papillomavirus Vaccines

Candidate prophylactic vaccines based on papillomavirus L1 virus-like particles (VLPs) are currently in human clinical trials. The main long-term goal of the vaccine is to reduce the incidence of cervical cancer and its precursors. In animal papillomavirus models, systemic immunization with L1 VLPs can induce high titers of neutralizing antibodies that confer protection against high-dose experimental papillomavirus challenge. In humans, systemic vaccination with L1 VLPs has been well tolerated and induced high serum antibody titers (at least 40 times higher than titers seen following natural infection). A recent proof of principle HPV16 L1 VLP efficacy trial has shown excellent protection against persistent HPV16 infection and associated cytological abnormalities. Large scale efficacy trials of L1 VLPs from HPV16 and 18 (the HPV types found most frequently in cervical cancer), with or without HPV6 and 11 (the HPV types responsible for most genital warts), are planned. If the results of these large trials support the encouraging results of the early trials, they should lead to a commercial prophylactic HPV vaccine. Implementation issues may include how to make the vaccine available in the developing world, where the majority of cervical cancer cases occur, the appropriate age of vaccination, and the role of male vaccination. Because a VLP vaccine is likely to provide type-specific protection, increasing the number of cancer-associated HPV types in the vaccine is a likely approach to broadening the protection to additional types. There will probably also be efforts to develop alternative vaccine formulations better suited to implementation in developing countries as well as attempts to develop vaccines with a therapeutic activity against established HPV infection because a combined prophylactic/therapeutic vaccine may be expected to have an even greater impact than a purely prophylactic vaccine on HPV induced disease.

Insurance and safety after September 11, 2001: Coming to grips with the costs and threats of terrorism

This chapter, originally written as a consequence of the terrorist attacksof September 11, 2001, provides an elementary, everyday introduction tothe concepts of risk and insurance. Conceptually, risk has two dimensions:a potential loss, and the chance of that loss being realized. People can,however, transfer risk to insurance companies against the payment ofso-called premiums. In practice, however, one needs accurate assessmentsof both losses and probabilities to judge whether premiums are appropriate.For many risks, this poses little problem (e.g., life insurance); however,it is difficult to assess risks of many other kinds of events such as actsof terrorism. It is emphasized, that through evolution and learning, peopleare able to handle many of the common risks that they face in life. Butwhen people lack experience (e.g., new technologies, threats of terrorism),risk can only be assessed through imagination. Not surprisingly, insurancecompanies demand high prices when risks are poorly understood. In particular,the cost of insurance against possible acts of terrorism soared afterSeptember 11. How should people approach risk after the events of that day?Clearly, the world needs to protect itself from the acts of terrorists andother disturbed individuals. However, it is also important to address the root causes of such antisocial movements. It is, therefore, suggested thatprograms addressed at combatting ignorance, prejudice, and socialinequalities may be more effective premiums for reducing the risk ofterrosrtism than has been recognized to date.

Cutaneous Leishmaniasis caused by Leishmania guyanensis parasites is endemic in the North-East South America. There is, however, little information available concerning L. guyanensis infectivity and the immune response associated with different stages of the disease. In the following chapter we discuss the results obtained in human research with regard to the involvement of different types of immune cells and their roles during the development of infection with L. guyanensis parasites. We also provide a résumé on the status of animal models of L. guyanensis infection and emphasize how essential these models are so as to increase our knowledge of immunopathogenesis in the host and, thus, provide an indispensable tool to test new therapeutic strategies.
