Cervical cancer is the fourth most common malignancy in women worldwide, although it is preventable with prophylactic HPV vaccination. HPV transmission-dynamic models can predict the potential for the global elimination of cervical cancer. The random network model is a new approach that allows individuals to be followed, and to implement a given vaccination policy according to their clinical records. We developed an HPV transmission-dynamic model on a lifetime sexual partners network based on individual contacts, also accounting for the sexual behavior of men who have sex with men (MSM). We analyzed the decline in the prevalence of HPV infection in a scenario of 75% and 90% coverage for both sexes. An important herd immunity effect for men and women was observed in the heterosexual network, even with 75% coverage. However, HPV infections are persistent in the MSM population, with sustained circulation of the virus among unvaccinated individuals. Coverage around 75% of both sexes would be necessary to eliminate HPV-related conditions in women within five decades. Nevertheless, the variation in the decline in infection in the long term between a vaccination coverage of 75% and 90% is relatively small, suggesting that reaching coverage of around 70–75% in the heterosexual network may be enough to confer high protection. Nevertheless, HPV elimination may be achieved if men’s coverage is strictly controlled. This accurate representation of HPV transmission demonstrates the need to maintain high HPV vaccination coverage, especially in men, for whom the cost-effectiveness of vaccination is questioned.

Human papillomavirus (HPV) infection is one of the causes of cervical cancer which is preventable. The study was a cross-sectional study with the objective was to determine the Human papillomavirus (HPV) vaccination coverage among working women. A total 236 educated working women were selected purposively from different working places in Dhaka city. A pretested semi- structured questionnaire was used for data collection. The knowledge was assessed by using modified Blooms cut off points which was developed with cervical cancer and vaccine knowledge related questions. The study result revealed that among 236 working women 71.2% knew about the risk factor of cervical cancer. It was found that 92.8% knew about the way of prevention of cervical cancer respectively. The overall knowledge on cervical cancer and vaccine was found to be having good knowledge 21.2%, satisfactory knowledge 41.9% and poor knowledge 36.9%. Out of the total working women only 5.1% had HPV vaccination coverage. Reason behind non vaccinations, 50% mentioned had no knowledge about vaccine, 35.3% mentioned can’t decide and 8.9% mentioned high cost of vaccine. Significant association has been observed in between vaccination coverage with over all knowledge of cervical cancer (p value .04). It may be concluded that HPV vaccination coverage is very low which needs awareness program on this issues through mass media, educational session, counseling and so on to reduce human papillomavirus associated cancers as well as economic burden.

Hpv Prevalence

ObjectiveHuman papillomavirus (HPV) infection causes multiple cancers in both women and men. In China, both HPV vaccination and cervical cancer screening coverages are low. We aim to investigate the temporal and geographical trends of HPV DNA prevalence in heterosexual men, women, men who have sex with men (MSM) and people living with HIV (PLHIV) in China.MethodsWe conducted a systematic review, collecting publications in PubMed, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data from January 2000 to May 2017. A total of 247 studies were selected for this meta-analysis to estimate pooled HPV prevalence, incidence of cervical cancer and risk of infection for subgroups. Meta-regression was applied to identify contributing factors to prevalence heterogeneities.ResultsThe national HPV prevalence was 15.6% (95% CI (14.4% to 16.9%)) in women with normal cervical cytology, and Central China had the highest prevalence (20.5% (15.2% to 25.8%)). HPV prevalence in heterosexual men (14.5% (11.3% to 17.7%)) was comparable with that of women (OR=1.09 (0.98 to 1.17)), but HPV prevalence in MSM (59.9% (52.2% to 67.6%)) was significantly higher than that in heterosexual men (OR=8.81 (8.01 to 9.69)). HIV-positive women (45.0% (38.4% to 51.6%)) and HIV-positive MSM (87.5% (82.3% to 90.9%)) had 4.67 (3.61 to 6.03) and 6.46 (5.20 to 8.02) times higher risk of HPV infection than their HIV negative counterparts.ConclusionHPV infection is prevalent in China, particularly in Central China, in comparison with the global level and neighbouring countries. Targeted HPV vaccination for women, MSM and PLHIV and scale-up of cervical screening for women are priorities in curbing the HPV epidemic in China.

The Cost

Apart from cervical cancer, Human papillomavirus (HPV) infection is associated with head and neck as well as other anogenital cancers such as vulva, vagina, anus, and penis. HPV vaccine provides specific protection against the disease and its subsequent manifestations.Vaccination programs for men tend to improve population-level control of HPV infection and directly prevent HPV related disease such as anogenital warts and oropharyngeal cancers in males. HPV vaccine does not treat existing infection or lesions/cancer and is intended for individuals before initiation fo sexual activity or any other form of exposure to HPV.Many programs across the globe do not include vaccination for boys because of the cost and little recognition of the emerging epidemic of HPV associated cancers in men. In the Indian context, as screening is not feasible for non-cervical HPV associated cancers, its incidence mostly among men will continue to rise until the present generation of vaccinated adolescents reaches their middle-age.Vaccination will reduce transmission rates and increase herd immunity. This in-turn, will prevent not just cervical cancers but also other HPV-associated malignancies among men and women.

The article provides a literature review on the prevention of cervical cancer by human papillomavirus (HPV) vaccination. Currently, 3 vaccines are available: the 4-valent vaccine against HPV types 6, 11, 16 and 18, the 9-valent vaccine against HPV types 6, 11, 16, 18, 31, 33, 45, 52, 58 and the bivalent vaccine against HPV types 16 and 18. Vaccination provides protection for women and men against infection with HPV and further development of HPV-associated diseases. Following immunization, seroconversion develops in 93-100% of women and in 99-100% of men and is effective in preventing incident and persistent HPV infection as well as cervical intraepithelial neoplasia. HPV immunization is ineffective in treating an existing HPV infection, genital warts, or anogenital intraepithelial neoplasia. HPV vaccination status does not affect recommendations for cervical cancer screening.

Background: Human Papilloma Virus (HPV) is the leading risk factor of cervical cancer. World Health Organization (WHO) has recommended including HPV vaccination in national immunization programs in all countries. Specifically, Jakarta Province has been implementing HPV vaccination since 2016. In this case, several factors influence vaccination coverage. However, there is limited evidence about determinants associated with HPV vaccination. Therefore, this study aimed to investigate the factors associated with HPV vaccination among elementary students in Central Jakarta.Methods: This was a cross-sectional study conducted from March until June 2020. The study population involved 167 female students of the 6th level of the elementary school in Central Jakarta. There were eight elementary schools in Kemayoran and Cempaka Putih Sub Districts selected purposively. Primary data was collected employing an online questionnaire, which was fulfilled by respondents (mothers and students). Data were analyzed utilizing statistic software for descriptive and bivariate analysis. For the bivariate analysis, Chi-Square Test was performed.Results: The HPV vaccination coverage was 80.84%. It was also showed that the last education level of the respondents’ father and mother was mainly senior high school (SMA) for 50.3% and 47.9%, respectively. The mothers’ knowledge was mainly in the middle (56.9%), and they had a positive attitude/support (67.1%). There were only 2.4% of the respondents with a family history of cervical cancer. In terms of family economic status, the main part of respondents had low expenditure for 2-3 million IDR (59.3%) a month. Meanwhile, human resources (vaccination providers) and HPV vaccine were 100% available in the vaccination service. Of the respondent, 47.9% of those said that the vaccine price was affordable. Children who had no support to get HPV vaccination from their father, mother, and siblings were 14.4%, 6.6%, and 21.6%, respectively. Besides, children who were not supported by their teachers was 3.6% and not supported by their peers was 23.4%. Meanwhile, father and mother’s supports were significantly associated with HPV vaccination.Conclusions: Factors associated with HPV vaccination were the support from the father and mother.

<p class="abstract">Persistent infection with human papilloma virus (HPV) has been proved beyond doubt to be associated with the development of cervical cancer. One woman dies of cervical cancer every 8 minutes in India. As per estimations for the year 2018, about 96922 new cervical cancer cases are diagnosed annually in India and it ranks as the second most common female cancer in all age groups. But being an infectious cause it is possible to contain its development and transmission. Coupled with this, we have a potent vaccine to fight this infection. A well documented account of positive impact of HPV vaccination has been published in numerous studies around the globe. By 2013, its vaccination had been introduced in about fifty countries around the globe. In India also, recently, two HPV vaccination projects for operational feasibility were launched in Andhra Pradesh and Gujarat. In November 2016, Punjab became the first state in the country to include the vaccine in its universal immunization program. This era belongs to women empowerment and we cannot deny them the opportunity of good health. Hence it’s high time India introduces an effective HPV vaccination program.</p>

HPV vaccine induces a herd immunity effect in genital warts when a large number of the population is vaccinated. That aspect should be taken into account when devising new vaccine strategies, like vaccination at older ages or male vaccination. Therefore it is important to develop mathematical models with good predictive capacities. We devised a sexual contact network that was calibrated to simulate the Spanish epidemiology of different HPV genotypes. Through this model we simulated the scenario that occurred in Australia in 2007, where 12-13 year-old girls where vaccinated with a three-dose schedule of a vaccine containing genotypes 6 and 11, that protect against genital warts, and also a catch-up program in women up to 26 years of age. Vaccine coverage were 73 % in girls with three doses and with coverage rates decreasing with age until 52 % for 20-26 year-olds. A fast 59 % reduction in the genital warts diagnoses occurred in the model in the first years after the start of the program, similar to what was described in the literature.

ABSTRACT The incidence of human papillomavirus (HPV) related cancers is growing in the United States. Active duty service members (ADSM) have higher rates of HPV infection than civilians and are therefore at greater risk of developing HPV-related cancers. The purpose of this commentary is to examine the burden of HPV-related cancers in ADSM. The current HPV vaccination and cervical cancer screening uptake rates of U.S. ADSM are presented, including a literature review of military-focused studies on HPV vaccination and cervical cancer screenings. We provide directions for future research, interventions, and policy recommendations to improve HPV-related cancer prevention among ADSM.
