Pediatrics 2024; 154:e2023064693. [PMID: 38978512 DOI: 10.1542/peds.2023-064693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 03/26/2024] [Accepted: 03/27/2024] [Indexed: 07/10/2024] Open
Abstract
BACKGROUND Nine-valent human papillomavirus (9vHPV) vaccines can be administered in 2 doses 6 to 12 months apart in adolescents. The impact of extended dose intervals is unknown. We report immunogenicity and safety data in adolescents of a second 9vHPV vaccine dose administered ≥1 year after the first. METHODS This open-label safety and immunogenicity study (NCT04708041) assessed extended-interval 2-dose regimens of 9vHPV vaccine among adolescents (10 to 15 years) who received 2 9vHPV vaccine doses: the first ≥1 year before enrollment, and second, at enrollment (day 1). We measured serologic responses to vaccine-targeted human papillomavirus (HPV) types at enrollment day 1 (pre-dose 2) and 1 month post-dose 2 (month 1) using a competitive LuminexV® immunoassay. We estimated effects of dose interval on geometric mean titers (GMTs) using regression modeling. Participants reported adverse events (AEs) through 15 days after vaccination. RESULTS We enrolled 146 adolescents (mean age 13.3 years) with median 25 months since first 9vHPV vaccine dose (range: 12-53 months). Across vaccine-targeted HPV types, GMTs increased from day 1 to month 1; seropositivity at month 1 was 100%. Anti-HPV GMTs at month 1 were not affected by differences in dose interval of 12 to 53 months, based on regression modeling. The most common AEs were mild-to-moderate injection site reactions; no serious AEs were reported. CONCLUSIONS Extending the interval between first and second 9vHPV vaccine doses to 12 to 53 months did not affect antibody responses, with favorable safety profile. These results support feasibility of extended interval regimens for 9vHPV vaccine.

Lescop J, Pennes B, Epaulard O. Mind the gap: Concordance between perceptions regarding vaccination as declared by patients and their evaluation by their general practitioner. Vaccine 2024; 42:310-314. [PMID: 38065770 DOI: 10.1016/j.vaccine.2023.11.065] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 11/29/2023] [Accepted: 11/30/2023] [Indexed: 01/01/2024]
Abstract
BACKGROUND The high level of vaccine hesitancy reported in the French population may lead general practitioners to anticipate difficult discussions on this topic. We aimed to assess the extent to which general practitioners' evaluation of their patients' vaccine hesitancy was correlated with the real vaccine hesitancy expressed by these patients. METHODS The study was based on two brief paper questionnaires completed in private by the general practitioner and the patient at the beginning of a medical appointment: one for the physician to evaluate on three quantitative and non-graduated visual scales (then analysed as a 0-100 scale) their patients' perceptions regarding vaccine safety, vaccine efficacy and 'being in favour of vaccination'; and one for the patient to express their perceptions for the same three axes using the same scales. RESULTS Overall, 31 physicians participated in the study, with 540 physician-patient pairs being included. The physicians' evaluation of patient perceptions was more positive when the physician was male (vs female), when the patient was male (vs female) and when both were males (vs both females). The median differences (in absolute values) between the physician evaluations and the patient perceptions were between 9 and 11 (on the 0-100 scale) for the three axes (vaccine safety, vaccine efficacy and 'being in favour'). A correlation was observed between the physicians' evaluation and the patients' declaration (Kendall test: vaccine efficacy: tau = 0.199, p < 0.001; vaccine safety: tau = 0.234, p < 0.001; being in favour of vaccination: tau = 0.365, p < 0.001). Physicians correctly classified 83.4 % of the patients with high perceptions of vaccine safety and efficacy (>75/100 for both scales) but only 54.5 % of those with low perceptions (<75/100 for both scales). CONCLUSION Physicians tend to correctly identify patients with the most favourable perceptions about vaccination but not those with the least favourable perceptions.

Abstract
In 2006, the human papillomavirus (HPV) vaccine was approved for use as an effective intervention for reducing the risk of developing cervical cancer; however, its successful implementation is dependent on acceptability. This study aims to provide a comprehensive understanding of the reasons that favor or do not favor the acceptability of HPV vaccines. METHODS We conducted a systematic review and meta-summary of qualitative research on 16 databases. A total of 32 articles that considered the perspectives of vaccine users, their parents, and the professionals who care for them were reviewed. Synthesis was conducted as described by Sandelowski and Barroso. RESULTS We used inductive and deductive methods to obtain a total of 22 dimensions, out of which three issues stood out that should be considered to improve acceptability and are formed by three groups of study, namely, information about the vaccine, fears and side effects, and sexuality associated with the vaccine. CONCLUSIONS Acceptability, as well as adherence to HPV vaccination, is a complex concept. This review highlights the perspectives of the three sets of actors involved in the process (i.e., users, parents, and professionals) and views these factors in relation to acceptability as a guide for new interventions.

Abstract
BACKGROUND Human papillomavirus (HPV) represents the most common STI in the USA. HPV inequities in prevention, diagnostics and clinical care persist. We define inequities as systematic, avoidable and unfair differences in health outcomes. OBJECTIVES The objectives of this scoping review are to chart existing data on HPV-related inequities, identify gaps in existing literature and guide future research to reduce these inequities. METHODS We completed a scoping review following guidelines from the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses scoping reviews extension. We performed a literature search on PubMed and Ovid Embase in July 2022 for articles pertaining to HPV and evaluating populations within the USA. We included English language publications from 2018 to 2022 evaluating at least one health inequity outlined by the National Institutes of Health. General publication characteristics and health inequity data were charted in a masked, duplicate fashion using a pilot-tested Google Form. We analysed frequencies of health inequities and summarised main findings from included studies. RESULTS Our final sample included 170 publications. The most common inequities examined were race/ethnicity (140 studies), sex or gender (97 studies), and income (69 studies). Many historically marginalised racial/ethnic groups had lower rates of HPV-related knowledge, vaccination and worse overall outcomes related to HPV. Compared with women, men had lower rates of HPV vaccination and provider recommendation, and higher rates of HPV-infection. Results regarding income were largely conflicting. CONCLUSION Findings from our review demonstrate clear gaps in HPV-related inequity research. Vaccine completion, provider recommendation and intersectionality should continue to be evaluated to implement targeted interventions.

Abstract
Cervical cancer remains a significant disease in the United States. Although the human papillomavirus (HPV) vaccine has been approved for those aged 9-26 years and for some individuals up to age 45 years, there are many circumstances in which health care professionals may not know whether the vaccine should be recommended, such as for patients with previous infection, health care workers, and those older than age 26 years. This article highlights the evidence that the HPV vaccine is a safe and highly effective way to prevent cervical cancer, with the strongest predictor of vaccine uptake being practitioner recommendation.

Abstract
BACKGROUND Willingness to vaccinate against coronavirus disease 2019 (COVID-19), which is vital to successful vaccination campaigns, is wavering and suboptimal. In Germany, quantitative research highlighted concerns regarding the safety and efficacy of COVID-19 vaccines as barriers to uptake, but qualitative insights regarding individuals' decisions about COVID-19 vaccines and how personal perceptions reflect or refute existing behavioral theories are lacking. METHODS To identify how individuals make COVID-19 vaccination decisions within real-life contexts, we conducted 33 semi-structured, in-depth qualitative interviews with individuals in Germany between March and April 2021 using maximum variation sampling, focusing on perceptions of COVID-19 vaccines. Analysis, informed by a framework approach, began in the field via debriefings and was amplified upon the conclusion of data collection. RESULTS Four interconnected themes (deliberation, context, emotion, trust) shaped respondents' decisions about vaccination. Personal deliberation regarding benefits and risks of vaccines and perceptions of the broader social and political context sparked a spectrum of emotions that underpinned vaccination decisions. Trust in science and researchers emerged as a powerful protective factor facilitating the decision to get vaccinated even amidst a rapidly changing context and disconcerting information. CONCLUSIONS Our findings add to ongoing debates about the breadth of vaccination decisions by highlighting how respondents are influenced by their perceptions of the political context and the emotional heft of their decisions. The role of cognitive evaluation, context, and emotions mirrors other decision-making frameworks, particularly the Risk as Feelings Theory. We extend on the elements of this theory by highlighting trust as a protective factor when making decisions particularly in highly uncertain contexts. Success of vaccination campaigns, more important than ever as new variants of COVID-19 emerge, is interwoven with an ability to bolster trust in science. Communicating public-health decisions and information about vaccines transparently without instilling fear offers promising chances to strengthen public trust in COVID-19 vaccines.

Social determinants of human papillomavirus vaccine series completion among U.S. adolescents: A mixed-methods study. SSM Popul Health 2022; 18:101082. [PMID: 35493405 PMCID: PMC9038569 DOI: 10.1016/j.ssmph.2022.101082] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 02/16/2022] [Accepted: 03/23/2022] [Indexed: 11/20/2022] Open
Abstract
Introduction Human papillomavirus (HPV) vaccination can significantly reduce HPV-associated cancers. In the US, two doses are recommended for vaccine completion for younger adolescents. However, series completion rates remain below the nation's goal of 80% coverage. Multi-faceted factors may influence adolescent series completion. The purpose of this study was to identify individual-level, relationship-level, and community-level factors of timely series completion among adolescents, ages 11–14, initiating the HPV vaccine series in 2017. Methods A convergent, mixed-methods design was used combining adolescent electronic health record data (n = 803) and qualitative interviews with adolescents and their parents (n = 32) to assess timely series completion within 14-months (e.g., January 2018 to February 2019). Multivariable logistic regression analysis examined individual-level and community-level factors influencing timely series completion. Directed content analysis was used to identify relevant themes and subthemes. We provided an integrative summary to assess patterns of convergence or divergence between quantitative and qualitative data. Results In the quantitative phase, 61.0% of adolescents completed the vaccine series and 47.3% completed it on-time. Higher odds of timely series completion were among younger adolescents at vaccine initiation (aOR = 1.82, 95%CI = 1.07, 3.11) and lower among adolescents who were Black (aOR = 0.57, 95%CI = 0.37, 0.89) and Hispanic (aOR = 0.54, 95%CI = 0.30, 0.95) compared to Non-Hispanic White adolescents and those without private insurance (aOR = 0.56, 95%CI = 0.37, 0.85). Qualitative findings revealed increased risk for HPV at sexual debut as a motivator for timely series completion. Family/peers and healthcare providers influenced timely series completion among minority adolescents. Community-level factors were not significantly associated with timely series completion, however, qualitative findings revealed lack of transportation as a barrier to timely series completion. Conclusion Multi-level factors continue to influence timely series completion, despite fewer doses needed for series completion. Innovative strategies are needed to improve care coordination for receiving vaccine doses, patient-provider communication about series completion and increase access to HPV vaccine. Access barriers create challenges for teens to complete the HPV vaccine series. Racial/ethnic disparities in adolescent HPV vaccine series completion exist. Family and healthcare providers influence parents' decisions for series completion. Parents and adolescents continue to misunderstand the HPV vaccine schedule. Despite barriers, parents and teens are motivated to finish the HPV vaccine series.

Abstract
Background: Racial/ethnic minorities generally have a lower knowledge of human papillomavirus (HPV) and the HPV vaccine than non-Hispanic Whites. They are also less likely to have a regular healthcare provider (HCP). Given the role of HCPs in disseminating health information, we evaluated whether racial/ethnic disparities in HPV knowledge are moderated by regular HCP status. Methods: Data from the Health Information National Trends Survey Five (HINTS 5) Cycles One and Two (2017–2018) were analyzed. HPV and HPV vaccine knowledge were compared by regular HCP status across race/ethnicities. Independent partially-adjusted multivariable logistic regression models were used to assess the association between race/ethnicity and knowledge after controlling for sociodemographic characteristics. The resulting adjusted odds ratios were compared to those from fully-adjusted models that included HCP status. Results: After adjusting for regular HCP status, differences in knowledge persisted between racial/ethnic groups. Compared to Whites, Hispanics and Other race/ethnicities had significantly lower odds of having heard of HPV. Blacks, Hispanics, and Other race/ethnicities had significantly lower odds of having heard of the HPV vaccine. Conclusion: Racial/ethnic minorities had significantly lower levels of knowledge despite HCP status. These data suggest the need to address disparities in health information and strengthen provider–patient communication regarding HPV and the HPV vaccine.

Abstract
BACKGROUND Healthcare providers' (HCPs) recommendations for the Human Papillomavirus (HPV) vaccine are likely to increase the vaccination uptake. However, little is known about Ghanaian HCPs' general practices regarding HPV vaccination. We used Multi-Theory Model (MTM) constructs (i.e. participatory dialogue, behavioral confidence, environment, social and emotional transformation) to examine Ghanaian HCPs' attitudes towards HPV vaccination and their vaccination recommendation practices. METHODS We conducted three, 60-minute focus group discussions (FGDs) with HCP in the second-largest government hospital in Ghana. Sixteen semi-structured open-ended questions based on MTM constructs were used to guide the FGDs. We explored HCPs' general knowledge about HPV, vaccination recommendation behavior, physical environment, and socio-cultural factors associated with the HPV vaccination. Data from the FGDs were transcribed and thematically coded using NVivo software. RESULTS The sample of (n = 29) HCPs consisting of males (n = 15) and females (n = 14) between the ages of 29 and 42 years participated in the FGDs. Our analyses showed that HCPs (a) rarely offered HPV vaccination recommendations, (b) showed varied understanding about who should be vaccinated regarding age eligibility, gender, and infection status. Perceived barriers to HPV vaccination include (a) low urgency for vaccination education due to competing priorities such as malaria and HIV/AIDS; (b) lack of data on HPV vaccination; (c) lack of awareness about the vaccine safety and efficacy; (c) lack of HPV vaccine accessibility and (d) stigma, misconceptions and religious objections. HCPs expressed that their motivation for counseling their clients about HPV vaccination would be increased by having more knowledge about the vaccine's efficacy and safety, and the involvement of the parents, chiefs, churches, and opinion leaders in the vaccination programs. CONCLUSION The study's findings underscore the need for a comprehensive HPV vaccination education for HCPs in Ghana. Future HPV vaccination education programs should include information about the efficacy of the vaccine and effective vaccination messages to help mitigate HPV vaccine-related stigma.

Abstract
OBJECTIVES To evaluate the effectiveness of a stepped-wedge randomized trial of Development of Systems and Education for Human Papillomavirus Vaccination (DOSE HPV), a multilevel intervention. METHODS DOSE HPV is a 7-session program that includes interprofessional provider education, communication training, data feedback, and tailored systems change. Five primary care pediatric and/or family medicine practices completed interventions between 2016 and 2018; all chose to initiate vaccination at ages 9 to 10. We compared vaccination rates in the preintervention, intervention, and postintervention periods among 9- to 17-year-olds using random-effects generalized linear regression models appropriate for stepped-wedge design, accounting for calendar time and clustering of patients by providers and clinic. Outcomes included (1) the likelihood that eligible patients would receive vaccination during clinic visits; (2) the likelihood that adolescents would complete the series by age 13; and (3) the cumulative effect on population-level vaccine initiation and completion rates. Postintervention periods ranged from 6 to 18 months. RESULTS In the intervention and postintervention periods, the adjusted likelihood of vaccination at an eligible visit increased by >10 percentage points for ages 9 to 10 and 11 to 12, and completion of the vaccine series by age 13 increased by 4 percentage points (P < .001 for all comparisons). Population-level vaccine initiation coverage increased from 75% (preintervention) to 84% (intervention) to 90% (postintervention), and completion increased from 60% (preintervention) to 63% (intervention) to 69% (postintervention). CONCLUSIONS Multilevel interventions that include provider education, data feedback, tailored systems changes, and early initiation of the human papillomavirus vaccine series may improve vaccine series initiation and completion beyond the conclusion of the intervention period.

[PMID: 31108236 DOI: 10.1016/j.acap.2019.05.002] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2018] [Revised: 04/18/2019] [Accepted: 05/04/2019] [Indexed: 11/25/2022]
Abstract
OBJECTIVE Human papillomavirus (HPV) vaccine has been recommended for male patients for the prevention of genital warts and precancerous anal lesions since 2009. Our objective was to characterize race and insurance-based disparities in HPV vaccine completion among male patients who initiated the HPV vaccine series. METHODS This was a retrospective cohort study of adolescent male patients in a primary care network who initiated the HPV vaccine series from October 2009 to December 2013. We measured vaccine series completion as the primary outcome. We evaluated associations between outcomes and race and insurance status, controlling for potential confounders and effect modification with multivariable logistic regression. Analyses were stratified by vaccine recommendation era (permissive vs routine). RESULTS In total, 42% of males in the cohort (16,691) completed the vaccine series. In the permissive vaccine era (2009-2011), non-black patients (53%) were more likely to complete than black patients (32%) and non-Medicaid patients (49%) were more likely to complete than Medicaid patients (33%). These differences persisted in the routine recommendation era (2012-2013). In both the permissive and routine eras, Medicaid insurance was associated with a larger reduction in the predicted probability of vaccine series completion for non-black patients. Adherence to the recommended vaccination schedule was low, with a median time to completion of 8.9 months. Using the updated completion schedule (2016), we found that completion rates were greater (54.1%) with continued differences based on race (60% vs 45.7% for non-black vs black patients) and insurance (57.4% vs 46.4% completion for non-Medicaid vs Medicaid patients). CONCLUSIONS We found significant disparities in HPV vaccine series completion rates among male patients based on race and insurance, unchanged based on era of initiation or visit frequency.

Beliefs around childhood vaccines in the United States: A systematic review. Vaccine 2019; 37:6793-6802. [PMID: 31562000 DOI: 10.1016/j.vaccine.2019.08.068] [Citation(s) in RCA: 53] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 07/30/2019] [Accepted: 08/26/2019] [Indexed: 01/22/2023]
Abstract
BACKGROUND While childhood vaccines are safe and effective, some parents remain hesitant to vaccinate their children, which has led to outbreaks of vaccine preventable diseases. The goal of this systematic review was to identify and summarize the range of beliefs around childhood vaccines elicited using open-ended questions, which are better suited for discovering beliefs compared to closed-ended questions. METHODS PubMed, Embase, and PsycINFO were searched using keywords for childhood vaccines, decision makers, beliefs, and attitudes to identify studies that collected primary data using a variety of open-ended questions regarding routine childhood vaccine beliefs in the United States. Study designs, population characteristics, vaccine types, and vaccine beliefs were abstracted. We conducted a qualitative analysis to conceptualize beliefs into themes and generated descriptive statistics. RESULTS Of 1727 studies identified, 71 were included, focusing largely on parents (including in general, and those who were vaccine hesitant or at risk of hesitancy). Seven themes emerged: Adverse effects was most prominent, followed by mistrust, perceived lack of necessity, pro-vaccine opinions, skepticism about effectiveness, desire for autonomy, and morality concerns. The most commonly described beliefs included that vaccines can cause illnesses; a child's immune system can be overwhelmed if receiving too many vaccines at once; vaccines contain harmful ingredients; younger children are more susceptible to vaccine adverse events; the purpose of vaccines is profit-making; and naturally developed immunity is better than that acquired from vaccines. Nearly a third of the studies exclusively assessed minority populations, and more than half of the studies examined beliefs only regarding HPV vaccine. CONCLUSIONS Few studies used open-ended questions to elicit beliefs about vaccines. Many of the studies that did so, focused on HPV vaccine. Concerns about vaccine safety were the most commonly stated beliefs about childhood vaccines, likely because studies were designed to capture barriers and challenges to vaccination.

Abstract
OBJECTIVES Uptake and completion of the human papillomavirus (HPV) vaccine series among adolescents are suboptimal in the United States. We examined immunization registry data to determine completion of the 3-dose HPV vaccine series among adolescents in Seattle, Washington, born during 1995-2000 who received ≥1 dose of HPV vaccine. METHODS Immunization data included the administrating facility, which identified adolescents who used school-based health centers (SBHCs) for any HPV vaccine dose. We calculated completion of the 3-dose series at any time and on time by the 13th birthday. We stratified analyses by sex and assessed differences in on-time and any-time completion between users and nonusers of SBHCs. RESULTS Overall, 67.9% (8612 of 12 676) of females and 41.8% (3560 of 8521) of males with ≥1 dose of HPV vaccine completed the 3-dose series. Compared with female SBHC nonusers, female SBHC users had 37% higher odds of completing the series at any time (adjusted odds ratio [aOR] = 1.37; 95% CI, 1.19-1.58) and 33% higher odds of completing the series on time (aOR = 1.33; 95% CI, 1.08-1.64). Compared with male SBHC nonusers, male SBHC users had 45% higher odds of completing the series at any time (aOR = 1.45; 95% CI, 1.23-1.70) and 79% higher odds of completing the series on time (aOR = 1.79; 95% CI, 1.11-2.89). CONCLUSION Adolescent SBHC users had higher odds of completing the HPV vaccine series than adolescents who received all doses in traditional health care settings. SBHCs should be leveraged to increase adolescent immunization rates.

Educating healthcare providers to increase Human Papillomavirus (HPV) vaccination rates: A Qualitative Systematic Review. Vaccine X 2019; 3:100037. [PMID: 31463471 PMCID: PMC6708991 DOI: 10.1016/j.jvacx.2019.100037] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 06/25/2019] [Accepted: 07/25/2019] [Indexed: 11/22/2022] Open
Abstract
Objectives HPV vaccination rates in the United States lag behind other developed countries. Educational interventions are primarily directed at patients and parents rather than healthcare providers (HCPs), despite evidence that provider recommendation is a key determinant of vaccine uptake. The objectives for this review are to synthesize the available evidence related to the knowledge, attitudes, and beliefs of HCPs surrounding HPV vaccination, to summarize provider-specific educational interventions which have been evaluated, and to review existing provider-specific educational resources from national organizations and whether they align with the gaps identified. Methods A systematic search was performed using PubMed, Web of Science, CINAHL, and ERIC with MeSH terms human papillomavirus, vaccine, education, workshop, training, knowledge, attitude, belief, intention, and healthcare provider. Full text articles were obtained for studies that described the knowledge and attitudes of providers and/or impact of educational interventions. Data extraction was performed by four independent reviewers. Websites of American organizations with an interest in HPV vaccination were manually searched for provider resources. Results 1066 publications were identified, and 98 articles were fully reviewed with 40 ultimately included. Providers’ knowledge on HPV was generally low with a correspondingly low vaccine recommendation rate. Provider-specific education (e.g., didactic session and communication training) with complimentary interventions demonstrated increased knowledge and vaccine series initiation and completion. Themes identified in descriptive studies highlighted providers’ lack of general HPV and vaccine knowledge, low self-confidence in counselling and addressing parental concerns, and discomfort in discussing sexual issues related to vaccination. Many American organizations have provider-specific resources; however, the effectiveness of these materials has not been established. Conclusions HPV knowledge among providers remains low. Educational interventions to improve knowledge and communication appear to be effective. A breadth of resources from national organizations are available but their efficacy and level of utilization is largely unknown. Coordinated efforts are needed to evaluate provider-specific educational resources to improve vaccine uptake in the US.

Immunization Campaigns and Strategies against Human Papillomavirus in Italy: The Results of a Survey to Regional and Local Health Units Representatives. BIOMED RESEARCH INTERNATIONAL 2019; 2019:6764154.

Abstract
Objective. The study aimed to assess the impact of HPV immunization campaigns organizational aspects, the characteristics of immunization program (vaccination targets and type of offer), and communicative strategies adopted by four Italian administrative regions on vaccination coverage observed. Methods. From November 2017 to March 2018, regional and Local Health Units (LHUs) representatives were invited to complete an online survey including 54 questions evaluating vaccination invite systems, access systems to vaccination centres, reminder and recall systems, and adverse events surveillance. An overall descriptive analysis was conducted. Since observed vaccine coverage (VC) obtained in females (2002-2004 birth cohorts) was lower than objectives fixed by the Italian Ministry of Health, variables were assessed using the national VC mean obtained in the 2003 girls birth cohort as outcome. Results. Twenty-six LHUs belonging to 4 Northern and Southern Italian regions participated in the study. Organizational aspects significantly related to VC lower than the national mean were access to vaccine centres without appointment and parents' reservation as appointment planning system. Recall systems for both the first and the second dose, including the appointment in the invitation letter, the availability of regional immunization registry, and education of healthcare workers on universal HPV immunization strategies, instead, were related to higher VC. As regards preadolescent immunization strategies, both VC obtained in girls and boys were far from the Ministerial goals. Only 20% of LHUs introduced multicohort female strategies while all LHUs adopted copayment targeting both men and women. Immunizations strategies targeting subjects at risk were implemented only in half of participating LHUs. Conclusions. VC observed in participating LHUs are largely lower than the national objectives in all anti-HPV vaccine targets. Both organizational and educational strategies have to be implemented to improve the VC goals.

Abstract
We described the relative contributions of parental intention and provider recommendation style to HPV and meningococcal vaccine receipt. Parent-child dyads that were eligible for both meningococcal and HPV vaccines participated in pre-visit surveys and consented to audio recording of their clinical interactions with healthcare providers related to vaccination. Surveys were analyzed for parent and child demographics and parental intention to vaccinate children with HPV and/or meningococcal vaccines. Audio recordings were analyzed for provider recommendation style, defined as indicated (provider stated vaccine was due at that visit) or not, and for child receipt of vaccines. Linear and logistic regression models were used to determine the relative contributions of parental intention and provider recommendation style to vaccine receipt. 56 parents/child dyads participated. 79% of children received HPV vaccines, and 93% received meningococcal vaccines. After controlling for demographic variables, parental intention did not differ by vaccine type. However, providers were less likely to use an indicated recommendation for HPV than for meningococcal vaccine. After controlling for demographic factors, parental intention, and provider recommendation style, vaccine type (HPV or meningococcal) was no longer associated with vaccine receipt Differences that were previously attributed to vaccine-specific factors may be explained by parents' and providers' roles in vaccine receipt. These findings suggest that interventions and policy recommendations regarding adolescent vaccination should focus on increasing parental demand for vaccines and ensuring that providers present all vaccines as the medical standard of care.

Abstract
OBJECTIVE Vaccination coverage against HPV in France is among the lowest in the industrialized world, although the public authorities have recently become aware of this issue. Few studies have looked at teenaged girls' representations of this vaccination, even though they are the most concerned by it. This qualitative study explored the experiences and representations of HPV vaccination by adolescent girls seeing doctors at least occasionally. STUDY DESIGN We used a written essay question to explore this issue among 101 adolescent girls at six urban medical centers and a semi-structured interview to discuss it in further depth with five of them. The analysis was lexicometric (ALCESTE®) and phenomenological (Interpretative Phenomenological Analysis). RESULTS These results are organized around four superordinate themes: the teenage girls' factual knowledge about this vaccine, their motives for and obstacles to vaccination, their involvement in this decision, and finally the need for information about and solutions to this issue. CONCLUSIONS Teenage girls know little about this vaccine and are more sensitive to the emotional discourse that surrounds it than to rational knowledge about it. The requirement for parental authorization for this vaccine reinforces the girls' lack of investment. Vaccination programs should integrate the HPV vaccine more thoroughly into general prevention concerning sexual health and should send a strong signal by offering minors anonymous vaccination free of charge, as is already the case in France for requests for contraception, the morning-after pill, elective abortion, and screening and treatment of sexually transmitted infections.

Abstract
This study evaluated the impact of health system-based outreach and reminders on human papillomavirus (HPV) vaccine series initiation and completion. Parents of 10 to 12 year olds (n = 1805) were randomized to receive either (1) an outreach letter and brochure recommending HPV vaccination followed by automated HPV vaccine reminders or (2) usual care. We interviewed a subset of 50 parents to assess program acceptability. Outcomes were HPV vaccine initiation during the study period and on-time series completion. Rates of HPV vaccine initiation during the study period (July 2015 to August 2016) were similar between the intervention and control groups, but initiation within 120 days of randomization was higher in the intervention group (23.6% and 18.8%, P = .04) as was completion during the study period (10.3% vs 6.8%, P = .04). Reminders for doses 2 and 3 did not affect completion. The program was acceptable to parents. This study provides evidence that health system-based outreach and reminders can improve HPV vaccination.

Abstract
Objective: To evaluate the efficacy of an intervention utilizing patient navigators (PNs) to 1) educate families on human papillomavirus (HPV) vaccination in a clinic setting and 2) provide personalized reminders for follow-up. Method: Families with 9-17 year-old children who had no record of completing the HPV vaccination series receiving primary or specialty care in 3 pediatric clinics were approached by PNs between February 1, 2015 and August 31, 2016. Demographic characteristics, visit type, preferred contact method, rates and correlates of completion, and appointments missed were analyzed. In addition, qualitative interviews of 21 providers and PNs assessed their perceptions of the program. Results: 1,391 adolescents were identified out of 2,162 patients approached as unvaccinated or partially vaccinated prior starters; among the unvaccinated, 930 received the 1st dose after being counseled by the PN (66.9%), either immediately or at a follow-up visit soon thereafter. This included 118 siblings of patients who did not have an appointment that day. Of initiators approached between 2/1/2015 and 8/31/2016, 93% (864/930) completed the series by 8/31/2017. No differences in series completion among initiators were observed by gender or race/ethnicity, but older patients (15-17 years old) were less likely to complete than 11-12 year olds. Of the 688 patients identified as prior starters, 85% completed the series through the program. Qualitative interviews demonstrated that providers felt the program addressed major barriers to HPV vaccination. Conclusion: Employing PNs dramatically increased HPV vaccine series completion among boys and girls with historically low HPV vaccination rates at pediatric clinics in Texas. Clinic providers felt this program addressed many barriers they observed prior to program implementation. This approach could markedly improve HPV vaccine series completion rates in the US.

Abstract
Background Each year, human papillomavirus (HPV) causes 30,000 cancers in the USA despite the availability of effective and safe vaccines. Uptake of HPV vaccine has been low and lags behind other adolescent vaccines. This protocol describes a multilevel intervention to improve HPV vaccination rates. Methods Using a cluster randomized trial, we will evaluate the independent and combined impact of two evidence-based implementation strategies with innovative enhancements on HPV vaccination rates for female and male patients. The clusters are six primary care sites providing care to pediatric populations. We will use a stepped-wedge cluster randomized design, including process evaluation, to test the hypothesis that compared with the current course of care and a practice-level intervention using reminder-recall interventions coupled with provider-level audit and feedback with education increases HPV vaccination rates in exposed clusters. The factorial design allows us to use a single trial to test these two interventions and to assess each individually and in combination. Our design has four 12-month steps. The first step will be a baseline period; data collected during it will provide a within-practice control group for each cluster. Second, two clusters will be randomly assigned to receive intervention 1 (reminder and recall), and two clusters will be randomly selected to receive intervention 2 (audit and feedback with education). Third, the other two clusters will be randomly allocated to intervention 1 or 2. Clusters initially with intervention 1 will be randomly allocated to 1 + 2 or 1; clusters initially with intervention 2 will be randomly allocated to 1 + 2 or 2. Fourth, all clusters will receive both interventions. To ensure balance of patient numbers across interventions, we will use block randomization at the first step, with the six clusters grouped into three pairs according to volume. Our primary outcome will be vaccination rates. Discussion Results of our clinical trial and process evaluation will provide evidence showing whether practice- and provider-level interventions improve HPV vaccination rates and will offer insight into contextual factors associated with direction and magnitude of trial outcomes. Trial registration ClinicalTrials.gov, NCT03501992, registered April 18, 2018.

Abstract
BACKGROUND Appropriate provider recommendation is crucial to raising HPV vaccination uptake, yet scant research has explored actual conversations between providers and parents, the effect of parental pre-visit vaccine intention on vaccination, or the effect of conversation style on parental satisfaction with that conversation. METHODS We analyzed 146 audio-recorded clinical encounters between providers, parents/guardians, and HPV vaccine-eligible adolescents, from May 2015 to March 2017, at eight practices in Northeastern U.S. Parents completed pre-visit measures of intent to vaccinate and post-visit assessments of satisfaction with vaccine conversations. We qualitatively analyzed transcribed audio recordings and evaluated associations between providers' vaccine introductions and vaccine receipt. RESULTS Provider recommendations were empirically defined as "indicated" (clear recommendation that the child receive HPV vaccination at that visit), "elective" (vaccination presented as optional), or "contraindicated" (delay recommended). The vaccination rates were 87%, 68%, and 0% following "indicated," "elective," and "contraindicated" presentations respectively. Providers' statements attesting to the vaccine's value to the child did not affect receipt. Parental pre-visit intent to vaccinate was associated with vaccine receipt: 100% for likely/very likely compared to 28% for very unlikely. The association between vaccine recommendation style and vaccine receipt was most pronounced with undecided parents, with 92% accepting vaccination after an "indicated" recommendation vs. 68% after an "elective" recommendation. Satisfaction with vaccine conversations was high regardless of recommendation style. CONCLUSIONS The results suggest that the words used to introduce HPV vaccination have the potential to inform parents' HPV vaccination decisions. Providers should be encouraged to simply state, "Your child is due for the HPV vaccine today."

Abstract
BACKGROUND Despite increasing awareness of the importance of a provider recommendation for HPV vaccine, the U.S. has yet to achieve the Healthy people 2020 goal of 80% series completion among adolescents. This failure indicates a need for further examination of the modifiable influences on parents' decision-making. Healthcare providers can influence parents' HPV vaccination decision-making, but little is known about parents' perspectives on the counseling they receive. We sought to assess U.S. parents' satisfaction with provider communication about HPV vaccine and associations with vaccination behaviors. METHODS Parents of 11-to-17-year-old adolescents who discussed HPV vaccination with a healthcare provider at least once (n = 795) completed our online survey in Fall 2016. We assessed their satisfaction with the discussion using the HPV Vaccine Communication Satisfaction Scale (α = 0.94). We examined associations between satisfaction (categorized as low, moderate, or high), and three vaccination behaviors: refusal/delay, series initiation (≥1 dose), and continuation (≥2 doses among initiators) using multivariable logistic regression. RESULTS Most parents reported high (36%) or moderate (38%) satisfaction with provider communication about HPV vaccination; fewer reported low (26%) satisfaction. Moderately satisfied parents (vs. low) had lower odds of refusal/delay (aOR = 0.59, 95% CI: 0.38-0.89), and higher odds of initiation (aOR = 1.71, 95% CI:1.15-2.55) and continuation (aOR = 2.05, 95% CI: 1.24-3.40). The associations were stronger for highly satisfied parents (refusal/delay aOR = 0.45, 95% CI: 0.29-0.70, initiation aOR = 3.59, 95% CI: 2.23-5.78, and continuation aOR = 4.08, 95% CI: 2.38-7.01). CONCLUSIONS Our study suggests that parent satisfaction with provider communication may play an important role in HPV vaccination decision-making. Yet, communication satisfaction has been largely unexamined in the HPV-vaccine literature to date. We introduce a brief, 7-item HPV Vaccine Communication Scale that can be used to assess parents' level of satisfaction with their provider's communication specific to HPV vaccine. We identify communication areas for providers to prioritize when discussing HPV vaccine with parents.

Acad Pediatr 2018; 18:S53-S65.

Abstract
Clinicians' recommendation for the human papillomavirus (HPV) vaccine appears to be an important driver of parental decisions about vaccination. Our aim was to synthesize the best available evidence exploring the perceptions and experiences regarding HPV vaccination, from the perspective of the US clinician. We conducted a comprehensive literature search of Academic Search Complete, CINAHL Plus, Communication & Mass Media Complete, Consumer Health Complete (EBSCOhost), ERIC, Health and Psychosocial Instruments, MEDLINE with full text, and PsycINFO databases. We identified 60 eligible articles: 48 quantitative and 12 qualitative. We extracted the following information: study purpose, use of theory, location, inclusion criteria, and health care provider classification. Results were organized into 5 categories: 1) clinicians' knowledge and beliefs about HPV and the HPV vaccine, 2) clinicians' attitudes and beliefs about recommending HPV vaccines, 3) clinicians' intention to recommend HPV vaccines, 4) clinicians' professional practices regarding HPV vaccination, and 5) patient HPV vaccination rates. Although clinicians were generally supportive of HPV vaccination, there was a discrepancy between clinicians' intentions, recommendation practices, and patient vaccination rates. Studies reported that clinicians tended not to provide strong, consistent recommendations, and were more likely to recommend HPV vaccines to girls versus boys and to older versus younger adolescents. Analyses revealed a number of facilitating factors and barriers to HPV vaccination at the clinician, parent/patient, and systems levels, including clinician knowledge, clinician beliefs, and office procedures that promote vaccination. This review provides an evidence base for multilevel interventions to improve clinician HPV vaccine recommendations and vaccination rates.

Abstract
PURPOSE To assess the effect of phone or text message reminders to parents of adolescents on human papillomavirus (HPV) vaccine series completion in Rochester, NY. METHODS We performed parallel randomized controlled trials of phone and text reminders for HPV vaccine for parents of 11- to 17-year olds in three urban primary care clinics. The main outcome measures were time to receipt of the third dose of HPV vaccine and HPV vaccination rates. RESULTS We enrolled 178 phone intervention (180 control) and 191 text intervention (200 control) participants. In multivariate survival analysis controlling for gender, age, practice, insurance, race, and ethnicity, the time from enrollment to receipt of the third HPV dose for those receiving a phone reminder compared with controls was not significant overall (hazard ratio [HR] = 1.30, p = .12) but was for those enrolling at dose 1 (HR = 1.91, p = .007). There was a significant difference in those receiving a text reminder compared with controls (HR = 2.34, p < .0001; an average of 71 days earlier). At the end of the study, 48% of phone intervention versus 40% of phone control (p = .34), and 49% of text intervention versus 30% of text control (p = .001) adolescents had received 3 HPV vaccine doses. CONCLUSIONS In this urban population of parents of adolescents, text message reminders for HPV vaccine completion for those who had already started the series were effective, whereas phone message reminders were only effective for those enrolled at dose 1.

Abstract
BACKGROUND Improving HPV vaccination coverage in the US will require healthcare providers to recommend the vaccine more effectively. To inform quality improvement efforts, we systematically reviewed studies of provider communication about HPV vaccination. METHODS We searched MEDLINE, CINAHL, EMBASE, and POPLINE in August 2015 to identify studies of provider communication about HPV vaccination. RESULTS We identified 101 qualitative and quantitative studies. Providers less often recommended HPV vaccine if they were uncomfortable discussing sex, perceived parents as hesitant, or believed patients to be low risk. Patients less often received recommendations if they were younger, male, or from racial/ethnic minorities. Despite parents' preference for unambiguous recommendations, providers often sent mixed messages by failing to endorse HPV vaccine strongly, differentiating it from other vaccines, and presenting it as an "optional" vaccine that could be delayed. CONCLUSION Interventions are needed to help providers deliver effective recommendations in the complex communication environment surrounding HPV vaccination.
