Progress in prophylactic human papillomavirus (HPV) vaccination in 2016: A literature review

Prophylactic human papillomavirus (HPV) vaccine represents a revolutionary step forward in preventing HPV-related cancers, especially cervical carcinoma. Alongside appropriate screening, it has the potential to dramatically reduce cervical cancer incidence and even eradicate it. Following extensive evaluations in clinical trials, the first decade of routine HPV vaccine use provides overwhelming evidence of the vaccines’ safety and their real-life effectiveness. In 2016, further clinical trials showed high vaccine efficacy in adult women, especially those that were HPV DNA-negative at baseline, and indicated possible protection from HPV-related diseases after treatment of precancerous cervical lesions. The recommendation for a two-dose schedule in individuals under 15 is further supported for all three licensed vaccines by immunogenicity studies that show non-inferior immune responses and similar clinical efficacy compared to the three-dose schedule. So far, natural competition between HPV types has not been confirmed and therefore vaccine-induced clinically significant type replacement is unlikely. The real-world effectiveness data showed cross-sectional reduction in the prevalence/incidence of vaccine-related HPV types, genital warts and precancerous cervical lesions in countries and regions with HPV vaccination coverage. These declines were evident not only in vaccinated females, but also in unvaccinated females and males, strongly suggesting herd protection. Despite an excellent safety profile consistently demonstrated in clinical trials and confirmed in real-life settings, recently invented controversial syndromes allegedly linked to HPV vaccines temporarily compromised some previously very successful vaccination programs and significantly contributed to the failure of HPV vaccine implementation in some countries with the highest prevalence of cervical cancer. However, several safety studies failed to confirm any association of these syndromes with HPV vaccination in various settings and geographic locations. The main challenges remain implementing HPV vaccination in national vaccination programs, especially in low-and middle-income countries with the highest burden of cervical cancer, and achieving and sustaining high vaccine coverage rates.

Area-based socioeconomic factors and Human Papillomavirus (HPV) vaccination among teen boys in the United States

BackgroundThis study is the first to examine associations between several area-based socioeconomic factors and human papillomavirus (HPV) vaccine uptake among boys in the United States (U.S.).MethodsData from the 2012-2013 National Immunization Survey-Teen restricted-use data were analyzed to examine associations of HPV vaccination initiation (receipt of ≥1 dose) and series completion (receipt of three doses) among boys aged 13-17 years (N = 19,518) with several individual-level and ZIP Code Tabulation Area (ZCTA) census measures. Multivariable logistic regression was used to estimate the odds of HPV vaccination initiation and series completion separately.ResultsIn 2012-2013 approximately 27.9% (95% CI 26.6%-29.2%) of boys initiated and 10.38% (95% CI 9.48%-11.29%) completed the HPV vaccine series. Area-based poverty was not statistically significantly associated with HPV vaccination initiation. It was, however, associated with series completion, with boys living in high-poverty areas (≥20% of residents living below poverty) having higher odds of completing the series (AOR 1.22, 95% CI 1.01-1.48) than boys in low-poverty areas (0-4.99%). Interactions between race/ethnicity and ZIP code-level poverty indicated that Hispanic boys living in high-poverty areas had a statistically significantly higher odds of HPV vaccine initiation (AOR 1.43, 95% CI 1.03-1.97) and series completion (AOR 1.56, 95% CI 1.05-2.32) than Hispanic boys in low-poverty areas. Non-Hispanic Black boys in high poverty areas had higher odds of initiation (AOR 2.23, 95% CI 1.33-3.75) and completion (AOR 2.61, 95% CI 1.06-6.44) than non-Hispanic Black boys in low-poverty areas. Rural/urban residence and population density were also significant factors, with boys from urban or densely populated areas having higher odds of initiation and completion compared to boys living in non-urban, less densely populated areas.ConclusionHigher HPV vaccination coverage in urban areas and among racial/ethnic minorities in areas with high poverty may be attributable to factors such as vaccine acceptance, health-care practices, and their access to HPV vaccines through the Vaccines for Children Program, which provides free vaccines to uninsured and under-insured children. Given the low HPV vaccination rates among boys in the U.S., these results provide important evidence to inform public health interventions to increase HPV vaccination.

Increasing Human Papillomavirus Vaccine Coverage Among Men Who Have Sex With Men-National HIV Behavioral Surveillance, United States, 2014.

Human papillomavirus (HPV) can cause oropharyngeal and anogenital cancers among men who have sex with men (MSM). In 2011, the Advisory Committee on Immunization Practices (ACIP) extended HPV vaccine recommendations to males through age 21 and MSM through age 26. Because of this distinction, vaccination for some MSM might rely on sexual behavior disclosure to health care providers. Receipt of ≥1 HPV vaccination among MSM aged 18-26 in National HIV Behavioral Surveillance (NHBS) was 4.9% in 2011. We evaluated HPV vaccine coverage and associated factors among MSM in 2014. Twenty US metropolitan statistical areas in 2014. Coverage was calculated as percentage of MSM self-reporting ≥1 HPV vaccination. Adjusted prevalence ratios were calculated from Poisson regression models to estimate associations of demographic and behavioral characteristics with HPV vaccination. Among 2892 MSM aged 18-26 years, HPV vaccine coverage was 17.2%. Overall, 2326 (80.4%) reported a health care visit within 12 months, and 2095 (72.4%) disclosed MSM attraction or behavior to a health care provider. Factors associated with vaccination included self-reported HIV infection; having a health care visit within 12 months, health insurance, or a usual place of care; and disclosing MSM attraction or behavior to a health care provider. Since the 2011 recommendation for vaccination of males, HPV vaccine coverage among MSM increased, but remains low. Most MSM reported a recent health care visit and disclosed sexual behavior, indicating opportunities for vaccination. Potential strategies for increasing MSM coverage include improving access to recommended care, and offering education for providers and patients.

Immunisation schedule of the Spanish Association of Paediatrics: 2017 recommendations

The Vaccine Advisory Committee of the Spanish Paediatrics Association (CAV-AEP) annually publishes the immunisation schedule which, in our opinion, is optimal for children resident in Spain, considering the evidence available on current vaccines. Pneumococcal and varicella immunisation in early childhood is already included in all of the funded vaccines present in the regional immunisation programmes. Furthermore, this Committee establishes recommendations about vaccines not included in official calendars (non-funded immunisations) such as like rotavirus, meningococcal B, and meningococcal ACWY.As regards funded immunisations, the 2+1 strategy (2, 4, 11–12 months) with hexavalent (DTPa-IPV-Hib-HB), and 13-valent pneumococcal vaccines are recommended.Administration of the 6-year booster dose with DTPa is recommended, and a poliomyelitis dose for children who had received the 2+1 scheme, as well as Tdap vaccine for adolescents and pregnant women between 27 and 32 weeks’ gestation.The two-dose scheme should be used for MMR (12months and 2–4years) and varicella (15months and 2–4years).Coverage of human papillomavirus vaccination in girls aged 12 with a two dose scheme (0, 6months) should be improved. Information and recommendation for male adolescents about potential beneficial effects of this immunisation should also be provided.Meningococcal ACWY vaccine is the optimal choice in adolescents.As regards the recommended unfunded immunisations, the CAV-AEP recommends the administration of meningococcal B vaccine, due to the current availability in Spanish community pharmacies, with a 3+1 scheme. The CAV-AEP requests the incorporation of this vaccine into the funded unified schedule. Vaccination against rotavirus is recommended in all infants.

The health and economic impact of scaling cervical cancer prevention in 50 low- and lower-middle-income countries.

To estimate the health impact, financial costs, and cost-effectiveness of scaling-up coverage of human papillomavirus (HPV) vaccination (young girls) and cervical cancer screening (women of screening age) for women in countries that will likely need donor assistance. We used a model-based approach to synthesize population, demographic, and epidemiological data from 50 low- and lower-middle-income countries. Models were used to project the costs (US$), lifetime health impact (cervical cancer cases, deaths averted), and cost-effectiveness (US$ per disability adjusted life year [DALY] averted) of: (1) two-dose HPV-16/18 vaccination of girls aged 10years; (2) once-in-a-lifetime screening, with treatment when needed, of women aged 35years with either HPV DNA testing or visual inspection with acetic acid (VIA); and (3) cervical cancer treatment over a 10-year roll-out. We estimated that both HPV vaccination and screening would be very cost-effective, and a comprehensive program could avert 5.2 million cases, 3.7 million deaths, and 22.0 million DALYs over the lifetimes of the intervention cohorts for a total 10-year program cost of US$3.2 billion. Investment in HPV vaccination of young girls and cervical cancer screen-and-treat programs in low- and lower-middle-income countries could avert a substantial burden of disease while providing good value for public health dollars.

Advocacy, communication, and partnerships: Mobilizing for effective, widespread cervical cancer prevention.

Both human papillomavirus (HPV) vaccination and screening/treatment are relatively simple and inexpensive to implement at all resource levels, and cervical cancer screening has been acknowledged as a "best buy" by the WHO. However, coverage with these interventions is low where they are needed most. Failure to launch or expand cervical cancer prevention programs is by and large due to the absence of dedicated funding, along with a lack of recognition of the urgent need to update policies that can hinder access to services. Clear and sustained communication, robust advocacy, and strategic partnerships are needed to inspire national governments and international bodies to action, including identifying and allocating sustainable program resources. There is significant momentum for expanding coverage of HPV vaccination and screening/preventive treatment in low-resource settings as evidenced by new global partnerships espousing this goal, and the participation of groups that previously had not focused on this critical health issue.

Human Papillomavirus Vaccination Among Young Men Who Have Sex With Men and Transgender Women in 2 US Cities, 2012-2014.

Since 2011, in the United States, quadrivalent human papillomavirus (HPV) vaccine has been recommended for boys aged 11 to 12 years, men through age 21, and men who have sex with men (MSM) through age 26. We assessed HPV vaccination coverage and factors associated with vaccination among young MSM (YMSM) and transgender women (TGW) in 2 cities. During 2012-2014, 808 YMSM and TGW aged 18 to 26 years reported vaccination status in a self-administered computerized questionnaire at 3 sexually transmitted disease (STD) clinics in Los Angeles and Chicago. Associations with HPV vaccination were assessed using bivariate and multivariable models to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). Few of the diverse participants (Hispanic/Latino, 38.0%; white, 27.0%; and black/African American, 17.9%) reported receiving 1 or more HPV vaccine doses (n = 111 [13.7%]) and even fewer reported 3 doses (n = 37 [4.6%]). A multivariable model found associations between vaccination and having a 4-year college degree or higher (aOR, 2.83; CI, 1.55-5.17) and self-reported STDs (aOR, 1.21; CI, 1.03-1.42). In a model including recommendation variables, the strongest predictor of vaccination was a health care provider recommendation (aOR, 11.85; CI, 6.70-20.98). Human papillomavirus vaccination coverage was low among YMSM and TGW in this 2-US city study. Our findings suggest further efforts are needed to reach YMSM seeking care in STD clinics, increase strong recommendations from health care providers, and integrate HPV vaccination with other clinical services such as STD testing.

Implementation of a human papillomavirus vaccination demonstration project in Malawi: successes and challenges

BackgroundCervical cancer is a major public health problem in Malawi. The age-standardized incidence and mortality rates are estimated to be 75.9 and 49.8 per 100,000 population, respectively. The availability of the human papillomavirus (HPV) vaccine presents an opportunity to reduce the morbidity and mortality associated with cervical cancer. In 2013, the country introduced a school-class-based HPV vaccination pilot project in two districts. The aim of this study was to evaluate HPV vaccine coverage, lessons learnt and challenges identified during the first three years of implementation.MethodsThis was an evaluation of the HPV vaccination project targeting adolescent girls aged 9–13 years conducted in Malawi from 2013 to 2016. We analysed programme data, supportive supervision reports and minutes of National HPV Task Force meetings to determine HPV vaccine coverage, reasons for partial or no vaccination and challenges. Administrative coverage was validated using a community-based coverage survey.ResultsA total of 26,766 in-school adolescent girls were fully vaccinated in the two pilot districts during the first three years of the programme. Of these; 2051 (7.7%) were under the age of 9 years, 884 (3.3%) were over the age of 13 years, and 23,831 (89.0%) were aged 9–13 years (the recommended age group). Of the 765 out-of-school adolescent girls aged 9–13 who were identified during the period, only 403 (52.7%) were fully vaccinated. In Zomba district, the coverage rates of fully vaccinated were 84.7%, 87.6% and 83.3% in year 1, year 2 and year 3 of the project, respectively. The overall coverage for the first three years was 82.7%, and the dropout rate was 7.7%. In Rumphi district, the rates of fully vaccinated coverage were 90.2% and 96.2% in year 1 and year 2, respectively, while the overall coverage was 91.3%, and the dropout rate was 4.9%. Administrative (facility-based) coverage for the first year was validated using a community-based cluster coverage survey. The majority of the coverage results were statistically similar, except for in Rumphi district, where community-based 3-dose coverage was higher than the corresponding administrative-coverage (94.2% vs 90.2%, p < 0.05), and overall (in both districts), facility-based 1-dose coverage was higher than the corresponding community-based (94.6% vs 92.6%, p < 0.05). Transferring out of the district, dropping out of school and refusal were some of the reasons for partial or no uptake of the vaccine.ConclusionIn Malawi, the implementation of a school-class-based HPV vaccination strategy was feasible and produced high (>80%) coverage. However, this strategy may be associated with the vaccination of under- and over-aged adolescent girls who are outside of the vaccine manufacturer’s stipulated age group (9–13 years). The health facility-based coverage for out-of-school adolescent girls produced low coverage, with only half of the target population being fully vaccinated. These findings highlight the need to assess the immunogenicity associated with the administration of a two-dose schedule to adolescent girls younger or older than 9–13 years and effectiveness of health facility-based strategy before rolling out the programme.

Variation in genital human papillomavirus infection prevalence and vaccination coverage among men and women in the USA.

Human papillomavirus (HPV) is the most common sexually transmitted infection that causes majority of anogenital and oropharyngeal cancers. Prophylactic HPV vaccine is available for the primary prevention of cancer and HPV transmission. Here, we are going to discuss the variation of HPV prevalence, HPV vaccination coverage and potential risk factors of men and women, retrieved from the cross-sectional study of the National Health Nutrition Examination Survey, a representative sample of noninstitutionalized, civilian residents in the USA. The overall penile HPV prevalence in men was 45.2% and the high risk oncogenic HPV prevalence defined by DNA testing was 25.1% that appeared to be widespread among all the age groups, which contrasts the vaginal HPV prevalence of 26.8% in women.

Declines in Human Papillomavirus (HPV)-Associated High-Grade Cervical Lesions After Introduction of HPV Vaccines in Connecticut, United States, 2008-2015.

Trends in human papillomavirus (HPV)-associated cervical lesions can provide an indication of vaccine impact. Our purpose was to measure trends in cervical lesions during 2008-2015 and to consider possible explanations including vaccination coverage, changes in screening for cervical cancer, and risk behaviors for acquiring HPV. Connecticut (CT) implemented mandatory reporting of cervical intraepithelial neoplasia grades 2/3 and adenocarcinoma in situ (cervical intraepithelial neoplasia grade 2 or higher [CIN2+]) in 2008. Trends by age and birth cohort were modeled using negative binomial regression and change-point methods. To evaluate possible explanations for changes, these trends were compared to changes in HPV vaccination coverage, cervical cancer screening, an antecedent event to detection of a high-grade lesion, and changes in sexual behaviors and Chlamydia trachomatis, an infection with similar epidemiology to and shared risk factors for HPV. A significant decline in CIN2+ was first evident among women aged 21 years in 2010, followed by successive declines in women aged 22-26 years during 2011-2012. During 2008-2015, the rates of CIN2+ declined by 30%-74% among women aged 21-26 years, with greater declines observed in the younger women. Birth cohorts between 1985 and 1994 all experienced significant declines during the surveillance period, ranging from 25% to 82%. Ecological comparisons revealed substantial increases in HPV vaccination during this time period, and more modest reductions in cervical cancer screening and sexual risk behaviors. The age and cohort patterns in our data suggest that declines in CIN2+ during 2008-2015 are more likely driven by HPV vaccination, introduced in 2006, than by changes in screening or risk behavior.

Passed the Age of Puberty: Organizational Networks as a Way to Get Things Done in the Health Field Comment on "Evaluating Global Health Partnerships: A Case Study of a Gavi HPV Vaccine Application Process in Uganda".

In this commentary I will demonstrate that the case study of Uganda’s Human papilloma virus (HPV) vaccine application partnership provides an excellent example of widening our lens by evaluating the successful HPV vaccine coverage from a network-centric perspective. That implies that the organizational network is seen as the locus of production and that network theories become indispensable to analyze the situation at hand. The case study is, as said, an excellent example of how this can be done and my comments have to be read as an endorsement and a broadening of the discussion of what Carol Kamya and colleagues have presented. It is demonstrated that an organizational network approach can be considered a serious and mature way in understanding public health issues.

Mapping information exposure on social media to explain differences in HPV vaccine coverage in the United States

BackgroundTogether with access, acceptance of vaccines affects human papillomavirus (HPV) vaccine coverage, yet little is known about media’s role. Our aim was to determine whether measures of information exposure derived from Twitter could be used to explain differences in coverage in the United States. MethodsWe conducted an analysis of exposure to information about HPV vaccines on Twitter, derived from 273.8 million exposures to 258,418 tweets posted between 1 October 2013 and 30 October 2015. Tweets were classified by topic using machine learning methods. Proportional exposure to each topic was used to construct multivariable models for predicting state-level HPV vaccine coverage, and compared to multivariable models constructed using socioeconomic factors: poverty, education, and insurance. Outcome measures included correlations between coverage and the individual topics and socioeconomic factors; and differences in the predictive performance of the multivariable models. ResultsTopics corresponding to media controversies were most closely correlated with coverage (both positively and negatively); education and insurance were highest among socioeconomic indicators. Measures of information exposure explained 68% of the variance in one dose 2015 HPV vaccine coverage in females (males: 63%). In comparison, models based on socioeconomic factors explained 42% of the variance in females (males: 40%). ConclusionsMeasures of information exposure derived from Twitter explained differences in coverage that were not explained by socioeconomic factors. Vaccine coverage was lower in states where safety concerns, misinformation, and conspiracies made up higher proportions of exposures, suggesting that negative representations of vaccines in the media may reflect or influence vaccine acceptance.

Improving Human Papillomavirus Vaccine Use in an Integrated Health System: Impact of a Provider and Staff Intervention

PurposeAcceptance and coverage of the human papillomavirus (HPV) vaccine in the United States has been suboptimal. We implemented a multifaceted provider and staff intervention over a 1-year period to promote HPV vaccination in a regional health care system. MethodsThe intervention was conducted in nine clinical departments from February 2015 to March 2016; 34 other departments served as controls. The intervention included in-person provider and staff education, quarterly feedback of vaccine coverage, and system-wide changes to patient reminder and recall notifications. Change in first-dose HPV vaccine coverage and series completion were estimated among 11- to 12-year-olds using generalized estimating equations adjusted for age and sex. ResultsHPV vaccine coverage in the intervention departments increased from 41% to 59%, and the increase was significantly greater than that seen in the control departments (32%–45%, p = .0002). The largest increase occurred in the quarter after completion of the provider and staff education and a patient reminder and recall postcard mailing (p = .004). Series completion also increased significantly system wide among adolescents aged 11–12 years following mailing of HPV vaccine reminder letters to parents of adolescents aged 12 years rather than 16 years. ConclusionsHPV vaccine uptake can be improved through a multifaceted approach that includes provider and staff education and patient reminder/recall. System-level change to optimize reminder and recall notices can have substantial impact on HPV vaccine utilization.

Human Papillomavirus Vaccine as an Anticancer Vaccine: Collaborative Efforts to Promote Human Papillomavirus Vaccine in the National Comprehensive Cancer Control Program.

Widespread use of the human papillomavirus (HPV) vaccine has the potential to reduce incidence from HPV-associated cancers. However, vaccine uptake among adolescents remains well below the Healthy People 2020 targets. The Centers for Disease Control and Prevention (CDC) National Comprehensive Cancer Control Program (NCCCP) awardees are well positioned to work with immunization programs to increase vaccine uptake. The CDC chronic disease management information system was queried for objectives and activities associated with HPV vaccine that were reported by NCCCP awardees from 2013 to 2016 as part of program reporting requirements. A content analysis was conducted on the query results to categorize interventions according to strategies outlined in The Guide to Community Preventive Services and the 2014 President's Cancer Panel report. Sixty-two percent of NCCCP awardees had planned or implemented at least one activity since 2013 to address low HPV vaccination coverage in their jurisdictions. Most NCCCP awardees (86%) reported community education activities, while 65% reported activities associated with provider education. Systems-based strategies such as client reminders or provider assessment and feedback were each reported by less than 25% of NCCCP awardees. Many NCCCP awardees report planning or implementing activities to address low HPV vaccination coverage, often in conjunction with state immunization programs. NCCCP awardees can play a role in increasing HPV vaccination coverage through their cancer prevention and control expertise and access to partners in the healthcare community.

Socioeconomic inequalities to accessing vaccination against human papillomavirus in France: Results of the Health, Health Care and Insurance Survey, 2012

BackgroundIn France, human papillomavirus (HPV) vaccination coverage among adolescents and young women is low and decreasing. We analysed data from the 2012 Health, Health Care and Insurance Survey with the aim of identifying factors associated with this vaccination. We also compared the socioeconomic profile of unvaccinated young women to that of women who do not undergo cervical cancer screening (CCS). MethodsData were collected through interviews and self-administered questionnaires completed by a randomised sample of Health insurance beneficiaries. Two analyses were performed using Poisson regression: one to investigate the determinants of CCS uptake in women aged 25–65 years old (n=4508), the other to investigate the determinants of HPV vaccination in young women aged 16–24 years old (n=899). A sub-analysis was performed in 685 “daughter–mother” couples from the same household in order to analyse the association between participation to CCS in mothers and HPV vaccination in daughters. ResultsFactors significantly associated both to a lower CCS uptake and to an insufficient HPV vaccination were the lack of a complementary private health insurance (P=0.023 and P=0.037, respectively) and living in a family with a low household income (P<0.001 and P=0.005, respectively). A low education level was associated to a lower CCS uptake (P<0.001). The absence of CCS uptake in the last three years in mothers was associated to a lower level of HPV vaccination in their daughter (P=0.014). ConclusionWomen who do not undergo CCS and HPV unvaccinated young women tend to be of modest socioeconomic status. Unvaccinated young females tend to have mothers who do not undergo CCS and are therefore at risk of benefiting from none of the two cervical cancer preventive measures. The current implementation strategy concerning HPV vaccination in France may therefore increase inequalities regarding cervical cancer prevention.

‘I don’t know if I’m making the right decision’: French mothers and HPV vaccination in a context of controversy

Human papillomavirus (HPV) vaccination coverage in France has fallen substantially since 2010 and the onset of a media controversy on the subject of its safety and efficacy. In this article we examine how and why mothers agree or do not agree to HPV vaccination for their daughters. We draw on data from a survey of French mothers of girls within the HPV vaccination target population (11–14 years old). We used semi-structured interviews to examine their perceptions of this relatively new vaccine and how such perceptions were shaped by their past experiences of vaccines and health in general. We also talked to them about their sources of information, their level of trust in these sources, and how their perception of risk changed as they accessed different and often contradictory information. We found that mothers’ fears of side effects and of ‘new’ vaccines was one of the main reason why they either refused to get their daughters vaccinated or hesitated. Mothers told us that they consulted several different sources, tended to trust their doctors most, but still questioned their recommendations. Although they presented the media and the Internet as untrustworthy, the information from those sources, whether gathered proactively or in passing, significantly influenced their decisions by introducing doubt or by prompting more information-seeking. In this article we show the dynamic nature of this decision-making process and we found that a substantial number of the mothers in our study said that they had been advised by at least one of their doctors not to have their daughter vaccinated.

Immunisation schedule of the Spanish Association of Paediatrics: 2017 recommendations

The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV- AEP) annually publishes the immunisation schedule which, in our opinion, is considered optimal for children resident in Spain, taking into account the evidence available on current vaccines. Pneumococcal and varicella immunisation in early childhood is already included in all funded vaccines present in the regional immunisation programmes. Furthermore, this committee establishes recommendations on vaccines not included in official calendars (non-funded immunisations), such as rotavirus, meningococcal B, and meningococcal ACWY. As regards funded immunisations, 2+1 strategy (2, 4, 11-12 months) with hexavalent (DTaP-IPV-Hib-HB) and 13-valent pneumococcal vaccines is recommended. Administration of the 6-year booster dose with DTaP is recommended, as well as a poliomyelitis dose for children who had received the 2+1 scheme, with the Tdap vaccine for adolescents and pregnant women between 27 and 32 weeks gestation. The two-dose scheme should be used for MMR (12 months and 2-4 years) and varicella (15 months and 2-4 years). Coverage of human papillomavirus vaccination in girls aged 12 with a two-dose scheme (0, 6 months) should be improved. Information and recommendations for male adolescents about potential beneficial effects of the tetravalent HPV vaccine should also be provided. ACWY meningococcal vaccine is the optimal choice in adolescents. For recommended unfunded immunisations, the CAV-AEP recommends the administration of meningococcal B vaccine, due to the current availability in Spanish community pharmacies, with a 3+1 scheme. CAV-AEP requests the incorporation of this vaccine in the funded unified schedule. Vaccination against rotavirus is recommended in all infants.

Prevalence of Genital Human Papillomavirus Infection and Human Papillomavirus Vaccination Rates Among US Adult Men

Human papillomavirus (HPV) is a common sexually transmitted infection that is a major cause of noncervical anogenital and oropharyngeal cancers. Prophylactic HPV vaccine is available for primary prevention. However, the population prevalence data for male genital HPV infection is not well known, while the HPV vaccination coverage is low in the United States. To estimate the prevalence of genital HPV infection and the HPV vaccination rate in the United States among adult men and to examine potential risk factors for HPV infection. The National Health and Nutrition Examination Survey (NHANES) samples a representative cross-section of the US population. Men aged 18 to 59 years were examined in mobile examination centers during the NHANES 2013-2014. DNA was extracted from self-collected penile swab specimens, and HPV genotyping was performed by polymerase chain reaction amplification. Demographic and vaccination information was gathered via self-report during home-based standardized interviews. Binary multivariable logistic regression was used to estimate the odds of HPV infection. The prevalence of genital HPV infection and the HPV vaccination coverage rate among adult men. During the NHANES 2013-2014, a total of 1868 men aged 18 to 59 years were examined. The overall genital HPV infection prevalence was 45.2% (95% CI, 41.3%-49.3%). The infection prevalence with at least 1 high-risk HPV subtype defined by DNA testing was 25.1% (95% CI, 23.0%-27.3%). In vaccine-eligible men, the prevalence of infection with at least 1 HPV strain targeted by the HPV 4-valent vaccine and HPV 9-valent vaccine was 7.1% (95% CI, 5.1%-9.5%) and 15.4% (95% CI, 11.7%-19.6%), respectively. Among vaccine-eligible men, the HPV vaccination coverage was 10.7% (95% CI, 7.8%-14.6%). Among men aged 18 to 59 years in the United States, the overall prevalence of genital HPV infection was 45.2% (95% CI, 41.3%-49.3%). The overall genital HPV infection prevalence appears to be widespread among all age groups of men, and the HPV vaccination coverage is low.
