We reviewed clinical and billing data from a university-based health system to assess HPV vaccine utilization among 9–18-year-old girls by individual, visit and medical specialty characteristics. Our sample included 10,082 adolescent patients with 27,928 visits to outpatient family medicine (FM), pediatric and gynecology clinics between January 2007 and March 2008. Vaccine series completion was low...
In this study, we developed a novel DNA vaccine for HPV; a recombinant baculovirus bearing human endogenous retrovirus (HERV) envelope protein, which cannot replicate in mammals, was used as a nano-carrier for HPV-16L1 DNA vaccine (AcHERV-HP16L1). For in vivo test, mice were injected intramuscularly with 107 particles of the constructs, with two boosts at 2-week intervals. Compared with Gardasil ...
Since its discovery, DNA vaccination has become an effective strategy for the development of vaccines against cancer including cervical carcinoma (CC). The formation of CC is associated with human papillomavirus (HPV) infection. Viral E6 and E7 oncoproteins are suitable targets for therapeutic vaccination. To adapt the HPV16 E6 oncogene for DNA immunisation, we performed several modifications. First...
From September 2008, older adolescent girls in the UK are eligible to have the HPV vaccine as part of the HPV vaccination ‘catch-up’ programme. Six months before they were due to be offered the vaccine 16–18 year old girls (N=617) from eight further education/sixth-form colleges reported their intentions to have the HPV vaccine and reasons for this decision. Most intended to have the vaccine (around...
Needle-free nonparenteral vaccines offer a number of practical advantages, especially in developing countries. To address the effects of vaccine administration route, we tested mucosal and systemic immune responses against human papillomavirus 16 L1(HPV16L1) protein using intranasal, intravaginal, transdermal, sublingual (SL) and intramuscular routes. The SL route provided the most effective mucosal...
This study provides Australian data on the incidence of human papillomavirus (HPV)-related oropharyngeal cancer to aid the debate on extending the HPV vaccination programme to males. The HPV status for 302 oropharyngeal cancers diagnosed between 1987 and 2006 was determined by HPV E6-targeted multiplex real-time PCR/p16 immunohistochemistry. The overall HPV-positivity rate was 36% (94% types 16 and...
The recent proliferation of studies describing factors associated with HPV vaccine acceptability could inform health care providers in improving vaccine coverage and support future research. This review examined measures of HPV and HPV-vaccine knowledge, attitudes, beliefs and acceptability, described psychometric characteristics, and provided recommendations about their use.A systematic search of...
Many countries are considering vaccination against human papillomavirus (HPV). However, the long-term impact of vaccination is difficult to predict due to uncertainty about the prevalence of HPV infection, pattern of sexual partnerships, progression of cervical neoplasias, accuracy of screening as well as the duration of infectiousness and immunity. Dynamic models of human papillomavirus (HPV) transmission...
The aim of this paper was to measure student knowledge of HPV and risks associated with cervical cancer, explore associated factors, correlate knowledge of HPV and cervical cancer with other domains of sexual health related knowledge and estimate student self-reported rates of HPV immunisation. Data were from a nationally representative cross-sectional stratified cluster sample of year 10 and 12 students...
Immunization with L1 as pentavalent capsomeres or virus-like particles (VLPs) generates high and long-lived titers of neutralizing antibodies and protection primarily against the human papillomavirus (HPV) type from which the vaccine was derived. Conversely, vaccination with L2 minor capsid protein derived from multiple HPV types induces lower titer, but more broadly neutralizing and protective antibody...
WHIM-syndrome is an inherited immunodeficiency disorder with abnormal susceptibility to human papillomavirus (HPV) infection and diseases. We determined safety and immunogenicity to a quadrivalent HPV vaccine in WHIM-syndrome by detection of HPV-specific antibodies and lymphoproliferation. In virus-like-particle (VLP)-ELISA, a WHIM patient showed antibody titers up to 400 for HPV-6/11/16/18, whereas...
Mathematical models of HPV vaccine effectiveness and cost-effectiveness have produced conflicting results. The aim of this study was to use mathematical models to compare and isolate the impact of the assumptions most commonly made when modeling the effectiveness of HPV vaccines. Our results clearly show that differences in how we model natural immunity, herd immunity, partnership duration, HPV types,...
Cervical cancer is the leading cause of cancer-related deaths among women worldwide. Current prophylactic vaccines based on HPV (Human papillomavirus) late gene protein L1 are ineffective in therapeutic settings. Therefore, there is an acute need for the development of therapeutic vaccines for HPV associated cancers. The HPV E7 oncoprotein is expressed in cervical cancer and has been associated with...
We have evaluated whether cholera toxin (CT) as a carrier/adjuvant can enhance human T-cell responses to a viral oncoprotein in vitro using dendritic cells (DCs) as antigen-presenting cells. Monocyte-derived DCs obtained from women with cervical dysplasia were pulsed with the HPV16 oncoprotein E7, either alone or conjugated to CT, and tested for their ability to induce antigen-specific activation...
A discrete choice experiment was developed to investigate if girls aged 12–16 years make trade-offs between various aspects of human papillomavirus (HPV) vaccination, and to elicit the relative weight that girls’ place on these characteristics. Degree of protection against cervical cancer, protection duration, risk of side-effects, and age of vaccination, all proved to influence girls’ preferences...
We assessed the public health impact and value of vaccinating boys and men with the quadrivalent HPV vaccine in the United States. We used mathematical population models, accounting for both the direct and indirect protective effects of vaccination. Inputs for the models were obtained from public data sources, published literature, and analyses of clinical trial data. Compared with a program of vaccinating...
We performed a mail-based survey of health education teachers in 6 states with diverse health education environments to better understand health education curricula in secondary schools related to adolescent vaccination and human papillomavirus (HPV) infection. Of the 198 respondents (response rate 68%), 66% and 71% reported teaching adolescents about recommended vaccines and HPV, respectively. Middle...
Cervical cancer is a leading cause of cancer-related deaths worldwide. The causal role of human papillomavirus (HPV) infection in the pathogenesis of cervical cancer has prompted the development of vaccines against HPV. The highest risk of HPV infection is in women aged 16–25 years. Almost all young adult women can benefit from HPV vaccination. There is strong epidemiological and clinical support...
Persistent infection with high-risk human papillomaviruses (HPVs) is the greatest risk factor for the development of HPV-associated cancers. In this study rabbits bearing persistent and potentially malignant papillomas were used to test the efficacy of vaccination with a recombinant DNA and/or vesicular stomatitis virus (VSV) targeting the cottontail rabbit papillomavirus (CRPV) E6 protein. Immune...
