To be effective, therapeutic cancer vaccines should stimulate both an effective cell-mediated and a robust cytotoxic CD8+ T-cell response against human papillomavirus (HPV)-infected cells to treat the pre-existing tumors and prevent potential future tumors. In this study, the therapeutic experiments were designed in order to evaluate antitumor effect against the syngeneic TC-1 tumor model. The anti-tumor efficacy of a HPV-16 E7 DNA vaccine adjuvanted with melatonin (MLT) was evaluated in a C57BL/6 mouse tumor model by measuring tumor growth post vaccination and the survival rate of tumor-bearing mice, analyzing the specific lymphocyte proliferation responses in control and vaccinated mice by MTT assay...

PURPOSE: Human papillomavirus is found in adults and adolescents and is associated with genital warts and cervical cancer. However, it has been detected in girls younger than 10 years old. Currently, there are no prevention methods for this age group, since it is not considered a risk group. The aim of this study was to evaluate the presence of infection and HPV subtype in girls under 9 years old attended at a referral service in the State of Espírito Santo, Brazil. METHODS: Forty-three girls younger than 9 years old had gynecological brush samples collected from vulval and perineal/anal regions...

PURPOSE: Despite improvement in vaccines against human papilloma virus (HPV), the causative agent of cervical cancer, screening women for cervical precancer will remain indispensable in the coming 30-40 years. A simple test that could be performed at home or at a doctor's practice and that informs the woman whether she is at risk would significantly help make a broader group of patients who aware that they need medical treatment. Cervical vaginal fluid (CVF) is a body fluid that is very well suited for such a test...

Background: Observational post-marketing studies are important to assess vaccine effectiveness (VE). We estimated VE from the bivalent human papillomavirus (HPV) vaccine against HPV positivity of vaccine and non-vaccine types in a high-risk population. Methods: We included all vaccine-eligible women from the PASSYON study, a biennial cross-sectional survey in Dutch sexually transmitted infection clinics. Vaginal swabs were analyzed using a PCR-based assay (SPF10-LiPA25) able to detect the 12 high-risk HPV (hrHPV) types 16/18/31/33/35/39/45/51/52/56/58/59...

Background: Recurrent respiratory papillomatosis is a rare but morbid disease caused by human papillomavirus (HPV) types 6 and 11. Infection is preventable through HPV vaccination. Following an extensive quadrivalent HPV vaccination program (females 12-26 years in 2007-2009) in Australia, we established a method to monitor incidence and demographics of juvenile-onset recurrent respiratory papillomatosis (JORRP) cases. Methods: The Australian Paediatric Surveillance Unit undertakes surveillance of rare pediatric diseases by contacting practitioners monthly...

Drawing upon health behavior change theories, the current study examined whether self-efficacy mediated relationships between social-cognitive factors (i.e., perceived risk, perceived benefits, perceived barriers, perceived severity, and cue to action) and human papillomavirus (HPV) vaccination intentions among college women. Unvaccinated women ( N = 115) aged 18 to 25 years attending a Midwestern university completed an anonymous web-based survey assessing study variables. Correlational analyses and mediation analyses were conducted...

A 50-year-old man with widespread manifestation of warts and distinct pruritus for the last 5 years was diagnosed with a reactivated human papillomavirus (HPV) infection by three, genetically verified types (6, 16, 18), which are included in the vaccine Gardasil®. Conventional treatment was not successful, but a rapid and significant reduction of the skin manifestation was observed after vaccination with Gardasil®. To what extent therapy-resistant infections with HPV can be influenced through an active HPV vaccination should be investigated in future trials...

BACKGROUND: Human papilloma virus vaccines are a safe and effective tool for reducing HPV infections that can cause cervical cancer. However, uptake of these vaccines has been suboptimal, with many people holding negative beliefs and misconceptions. Such beliefs have been linked with the experience of unpleasant side effects following medical treatment, and media coverage may heighten such concerns. METHODS: The present study sought to assess the influence of news coverage (number of news articles per month) on adverse event reporting in response to Gardasil vaccination in New Zealand over a 7...

BACKGROUND: Completed human papillomavirus (HPV) vaccination by age 16 years among women in Switzerland ranges from 17 to 75% across 26 cantons. The consequences of regional heterogeneity in vaccination coverage on transmission and prevalence of HPV-16 are unclear. METHODS: We developed a deterministic, population-based model that describes HPV-16 transmission among young adults within and between the 26 cantons of Switzerland. We parameterized the model using sexual behavior data from Switzerland and data from the Swiss National Vaccination Coverage Survey...

The currently available nonavalent human papillomavirus (HPV) vaccine exploits the highly antigenic L1 major capsid protein to promote high-titer neutralizing antibodies, but is limited to the HPV types included in the vaccine since the responses are highly type-specific. The limited cross-protection offered by the L1 virus-like particle (VLP) vaccine warrants further investigation into cross-protective L2 epitopes. The L2 proteins are yet to be fully characterized as to their precise placement in the virion...

Introduction: A promising approach to increase teenager's adherence to immunization against HPV is the administration of vaccinations within the school facilities. The Local Health Unit of Taranto experienced two different vaccine strategy proposals in the twelve-year-olds: the first one was the usual active call strategy in the outpatient clinic, while the second one provided the involvement of the schools in the area. The aim of the study is to evaluate the results of the proposed vaccination strategies in both sexes and in towns of different sizes in order to identify an effective path for achieving vaccine coverage improvement...

Global immunization efforts to date have heavily focused on infants and children, with noted success on public health. Healthy adolescents and adults contribute to the economic growth and development of countries but efforts to ensure vaccine coverage for these groups receive inadequate global attention and resources. Emerging epidemics for a number of infectious diseases including Ebola, Zika, dengue, malaria and the continuing epidemics of tuberculosis and several sexually transmitted infections, including HIV, HPV and Hepatitis B, have high incidence and prevalence in adolescents and adults...

BACKGROUND: Despite the introduction of Human papillomavirus (HPV) vaccination in national immunization programs (NIPs), vaccination rates in most countries remain relatively low. An understanding of the reasons underlying decisions about whether to vaccinate is essential in order to promote wider spread of HPV vaccination. This is particularly important in relation to policies seeking to address shortfalls in current HPV campaigns. The aim of this study was to explore prevailing perspectives concerning HPV vaccination among girls, boys, and parents, and so to identify potential determinants of HPV vaccination decisions in these groups...

Cervical cancer, resulting from infection with human papillomavirus (HPV)16, remains the fourth most common cancer in women worldwide. Recently, three prophylactic HPV vaccines targeting high-risk HPVs (particularly HPV16 and HPV18) have been implemented to protect younger women. However, individuals with pre-existing infections have no benefit from prophylactic vaccines. Thus, there is an urgent need to develop therapeutic vaccines. HPV16 E7 has been widely utilized as a target for immune therapy of HPV16-associated lesions or cancers, reflecting the sustained existence of this virus in cancerous cells...

Oroma Nwanodi, Helen Salisbury, Curtis Bay
Human papilloma virus (HPV) vaccine was developed to reduce HPV-attributable cancers, external genital warts (EGW), and recurrent respiratory papillomatosis. Adolescent HPV vaccination series completion rates are less than 40% in the United States of America, but up to 80% in Australia and the United Kingdom. Population-based herd immunity requires 80% or greater vaccination series completion rates. Pro-vaccination counseling facilitates increased vaccination rates. Multimodal counseling interventions may increase HPV vaccination series non-completers' HPV-attributable disease knowledge and HPV-attributable disease prophylaxis (vaccination) acceptance over a brief 14-sentence counseling intervention...
