background: cervical cancer is the most prevalent tumor in developing countries and the second most frequent cancer among female population worldwide. specific human papillomaviruses and, most notably, hpv types 16 and 18 are recognized as being caus-ally associated with cervical carcinomas. the early hpv type 16 genes, e6 and e7, di-rectly participate in the in vitro transformation of primary ...

BACKGROUND A vaccine against human papillomavirus (HPV) types 6, 11, 16 and 18 is now licensed for use in Canada and many other countries. We sought to estimate the number needed to vaccinate to prevent HPV-related diseases and death. METHODS A cohort model of the natural history of HPV infection was developed. Model simulations were based on 209 different parameter sets that reproduced Canad...

BACKGROUND Infection with HPV 16 and 18, the major causative agents of cervical cancer, can be prevented through vaccination with a bivalent or quadrivalent vaccine. Both vaccines provide cross-protection against HPV-types not included in the vaccines. In particular, the bivalent vaccine provides additional protection against HPV 31, 33, and 45 and the quadrivalent vaccine against HPV31. The qu...

BACKGROUND We tested the hypothesis that states with higher rates of cancers associated with human papillomavirus (HPV) would have lower HPV vaccine coverage. METHODS We gathered state-level data on HPV-related cancer rates and HPV vaccine initiation coverage for girls and boys, separately, and HPV vaccine follow-through (i.e., receipt of 3 doses among those initiating the series) for girls o...

BACKGROUND Cervical cancer claims the lives of 275,000 women each year; most of these deaths occur in low-or middle-income countries. In Kenya, cervical cancer is the leading cause of cancer-related mortality among women of reproductive age. Kenya's Ministry of Public Health and Sanitation has developed a comprehensive strategy to prevent cervical cancer, which includes plans for vaccinating pr...

Vaccines are commonly used as a preventive medicine for infectious diseases worldwide, however, clinical trials on an amyloid beta vaccine for Alzheimer's disease represents a new concept in the field of vaccinations. Several recent studies indicate the potential of therapeutic vaccines as well as classical vaccines as preventive medicines. A number of therapeutic vaccines for cancer have been ...

Background Immune based therapies for cancer are emerging as promising strategies to treat a number of malignancies. A more thorough biomarker assessment of the patients may provide insights into the variability in response to such immune therapies. In a Phase I/Ib clinical trial with the survivin-targeting vaccine DPX-Survivac, we showed the induction of robust immune responses in ovarian canc...

Interleukin 17 (IL-17) is produced during infection with Listeria monocytogenes and is also an important regulator of tumor development with both pro- and anti-tumorigenic effects. αβ T cells and γδ T cells are among the principle producers of IL-17 in response to infection and other proinflammatory conditions. Listeria-based cancer immunotherapies induce IFNγ directed Th1 dependent tumor regre...

We demonstrate that a poly(lactide-co-glycolide) (PLG) cancer vaccine can be used in combination with immune checkpoint antibodies, anti-CTLA-4 or anti-PD-1, to enhance cytotoxic T-cell (CTL) activity and induce the regression of solid B16 tumors in mice. Combination therapy obviated the need for vaccine boosting and significantly skewed intratumoral reactions toward CTL activity, resulting in ...

Human papillomavirus (HPV) infection is an event responsible for the development of cervical cancer and its premalignant dysplasia. Prophylactic vaccines based on virus-like particles (VLPs) have been successfully tested in clinical trials. They are safe, close to 100% effective in preventing persistent infection and premalignant disease, and are now being introduced onto the market. Vaccinatio...
