Abstract
The proliferation of anti-vaccination arguments is a threat to the success of many immunization programmes. Effective rebuttal of contrarian arguments requires an approach that goes beyond addressing flaws in the arguments, by also considering the attitude roots-that is, the underlying psychological attributes driving a person's belief-of opposition to vaccines. Here, through a pre-registered systematic literature review of 152 scientific articles and thematic analysis of anti-vaccination arguments, we developed a hierarchical taxonomy that relates common arguments and themes to 11 attitude roots that explain why an individual might express opposition to vaccination. We further validated our taxonomy on coronavirus disease 2019 anti-vaccination misinformation, through a combination of human coding and machine learning using natural language processing algorithms. Overall, the taxonomy serves as a theoretical framework to link expressed opposition of vaccines to their underlying psychological processes. This enables future work to develop targeted rebuttals and other interventions that address the underlying motives of anti-vaccination arguments.

Multilevel perspectives on school-based opportunities to improve HPV vaccination among medically underserved adolescents: Beyond school entry mandates. Hum Vaccin Immunother 2023; 19:2251815. [PMID: 37666253 PMCID: PMC10478734 DOI: 10.1080/21645515.2023.2251815] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2023] [Revised: 07/12/2023] [Accepted: 08/01/2023] [Indexed: 09/06/2023] Open
Abstract
School-based HPV vaccination programs have improved vaccine uptake among adolescents globally. However, school-based HPV vaccination strategies in the United States (US) have mainly focused on school-entry mandates for vaccination, which have passed in only five states/jurisdictions. Many schools and school-based health centers (SBHCs) already provide health services to medically underserved adolescents and opportunities to improve disparities in HPV vaccine education and uptake are underexplored. This qualitative study of clinic and community members assessed potential opportunities within and outside schools to increase HPV vaccination. Data were generated from a larger mixed-methods study designed to understand experiences with HPV vaccination evidence-based strategies in medically underserved communities. The parent study included interviews and focus groups conducted with clinic (providers, clinic leaders, staff) and community (racial/ethnic minority parents, advocates, payers, policy representatives) members in Los Angeles and New Jersey between December 2020-January 2022. We created a reduced dataset of text related to schools/SBHCs (30 in-depth interviews, 7 focus groups) and conducted a directed content analysis. Participants indicated that schools and SBHCs are ideal venues for reaching medically underserved adolescents experiencing barriers to primary care access. Parents/providers expressed mutual interest in HPV vaccine administration/education in schools, but some advocates/policy participants experienced challenges due to increasing politicization of vaccines. Participants highlighted policies for expanding HPV vaccine education and administration in schools, including minor consent and increasing SBHC funding for HPV vaccines. More research is needed to explore existing infrastructure, partner motivation, and opportunities to improve HPV vaccination among medically underserved adolescents within schools beyond vaccine mandates.

Abstract
School nurses frequently interact with school-age children and their parents/guardians regarding vaccinations. As a trusted source of information, the school nurse is in a unique position to share vaccine information with parents/guardians and school-age children that may dispel myths and, consequently, improve vaccination rates. Nevertheless, some parents/guardians are still reluctant to vaccinate their school-age children against Human Papilloma Virus (HPV) for a variety of reasons. Common barriers to HPV vaccination include a lack of understanding of the vaccine's purpose, concerns regarding the vaccine's safety, and insufficient recommendation from healthcare workers. However, school nurses have many duties in addition to ensuring vaccine compliance. School nurses may have difficulty remaining up-to-date on evidence-based answers to parents'/guardians' questions about HPV vaccine. Therefore, the purpose of this article is to provide school nurses with a quick reference question and answer guide to parents'/guardians' common HPV-related vaccination questions.

Abstract
State vaccine requirements are a tool for improving child and adolescent vaccination immunization coverage, but to be effective, parental buy-in is needed. The objective of this study was to assess the demographic, healthcare characteristics, and health beliefs associated with parental acceptance of general and HPV-specific state vaccine requirements. Indiana parents (N = 601) with children ages 11-17 years old completed a survey during March 2020.Results showed that 47.2% and 43.1% of parents believed there should always be general and HPV-specific state vaccine requirements, respectively. In multivariable analysis, higher odds of parental support for general state vaccine requirements were associated with being unsure whether HPV-associated cancer is a problem in the participant's county and having higher perceived benefits of HPV vaccines. Lower odds were associated with private insurance, having less than a bachelor's degree, and having less confidence in vaccines. In comparison, parents had higher odds of agreeing with HPV-specific state vaccine requirements if they reported higher interpersonal altruism and higher perceived benefits of HPV vaccines; they had lower odds if they were non-Hispanic White. Findings indicate that while similar percentages of parents agreed with general and HPV-specific state vaccine requirements, there were different characteristics associated with acceptance of each. Results can inform the development of tailored interventions for improving parental support for general and HPV-specific state vaccine requirements.

Abstract
Administration of the human papillomavirus (HPV) vaccine in early adolescence is effective in preventing cervical cancer, a common cancer in sub-Saharan Africa. Nigeria is in the pre-introduction era of the HPV vaccine. Understanding the preferences of the population for the vaccine can help design the HPV immunization program to ensure high uptake of the vaccine. This study explored the preferences for the HPV vaccine among stakeholders in selected communities in Ibadan, Nigeria. A discrete choice experiment survey based on six attributes of the HPV vaccine (which were the number of doses, the efficacy of the vaccine, cost of the vaccine, location of the service point, other benefits of the vaccine apart from prevention of cervical cancer and the odds of a side effect from the vaccine) was carried out in five communities. Data were analyzed using conditional and mixed logit models. Seven hundred community members were recruited, 144 (20.7%) were adolescents and 248 (35.4%) were males. In line with expectations, respondents preferred vaccines with higher efficacy, less severe side effects and lower costs. Preference heterogeneity was identified for adolescents that were less price-sensitive and other community members who were less likely to prefer using schools as the service point. The high socioeconomic class preferred a vaccine that also prevents genital warts. There were variabilities in the preferences for the attributes of the HPV vaccine in the study communities. These variabilities need to be considered in the introduction of the HPV vaccine to ensure high uptake of the vaccine.

Understanding parents' views toward the newly enacted HPV vaccine school entry policy in Puerto Rico: a qualitative study. BMC Public Health 2021; 21:1938. [PMID: 34696745 PMCID: PMC8544631 DOI: 10.1186/s12889-021-11952-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 09/28/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND The Human papillomavirus vaccine (HPV) is an essential tool for the prevention of HPV-related cancers. In Puerto Rico, the Secretary of Health established a school entry requirement of at least one dose of HPV vaccination in girls and boys aged 11 and 12 years, taking effect in August 2018. Our study aimed to examine parents' and guardians' views of unvaccinated children about the process of implementation of the new HPV vaccination school entry policy in Puerto Rico and identify potential barriers and facilitators related to the implementation of this requirement. METHODS During April through November 2019, we conducted three focus groups (n = 12) and eight in-depth semi-structured interviews with parents of children aged 11 and 12 who had not yet initiated the HPV vaccine series. The interview topics addressed were: perception of vaccination, HPV vaccine and it is inclusion as new school entry requirement practice, procedure of the sources of information, influencers, and willingness to change. The interviews were recorded and transcribed by our staff members. We identified emergent themes through thematic analysis. RESULTS The participants' perspective on the HPV vaccine school requirement was mixed. Lack of information of the HPV vaccines and lack of communication about the school-entry requirement were the themes most mentioned in the interviews. Moreover, previous negative experiences from friends or family members and adverse effects deterred some participants from vaccinating their kids. We discussed barriers in the process of soliciting an exemption. CONCLUSION Most barriers mentioned by study participants are modifiable. Information about the HPV vaccine mandate's implementation and educational materials regarding HPV vaccine safety need to be provided to address parents' concerns related to the vaccine's side effects. Schools (teachers, principal directors, and administrative staff), the government, and parent organizations need to be part of these efforts. This multilevel approach will help to improve disseminating information about HPV vaccination to clarify doubts and misinformation among parents.

Abstract
In 2018, Puerto Rico (PR) enacted a Human papillomavirus (HPV) vaccine school-entry requirement for students ages 11 to 12. Using the Consolidated Framework for Implementation Research (CFIR), we aimed to identify potential barriers and facilitators of this implementation. We conducted 38 qualitative interviews with stakeholders in PR from different organizations (Department of Health, Schools, Healthcare Providers, and Community organizations). We evaluated construct rating variability between the organizations to determine barriers and facilitators. The strongest facilitator determined was stakeholder's awareness of the parent's and student's needs to meet the HPV school-entry requirement. Other facilitators included initiatives for school-entry policies and the relative advantage of this requirement over different strategies. The strongest barriers included was the cost for private providers to administer the HPV vaccine, the negative influence of social media about the vaccine, which affected parents' acceptance, and the lack of school nurses as available staff resources for the school entry requirement. Findings from this study can be used to improve implementation (adaptations/modifications) and inform other states and countries in earlier stages of consideration of the adoption of similar immunization policies. Most barriers can be modifiable with the implementation of educational programs/training across schools, considering that they are the first line of response to parents of this school entry requirement.

Abstract
PURPOSE Vaccine requirements are effective population-based strategies to increase vaccination rates. In 2018, Puerto Rico's DOH announced that the HPV vaccine would be required for school entrance. This study explored arguments in favor of and against the HPV vaccine school-entry requirement in PR. METHODS We conducted a content analysis of two Puerto Rican newspapers. Articles (n = 286) published between 1/1/2015 and 7/31/2018 containing the Spanish terms for "HPV" and "human papillomavirus" were included. Data were summarized using descriptive statistics. Articles that mentioned the HPV vaccine school-entry requirement (n = 33) were reviewed qualitatively using applied thematic analysis. RESULTS The top five primary focus areas were education about HPV and the HPV vaccine, advertisements promoting the HPV vaccine, general vaccine information, cervical cancer and screening information, and the HPV vaccine school-entry requirement. Of the 33 articles that mentioned the requirement, 61% presented arguments in favor, 15% presented arguments against, 12% presented both arguments, and 12% only mentioned the existence of the requirement or were the DOH announcement. Arguments in favor centered on cancer prevention, high rates of HPV-associated cancers, and population wellness. Arguments against included worries about sexual transmission of HPV, HPV vaccine's side effects, issues related to the policy (e.g., mandatory), and lack of education. CONCLUSION Understanding reasons people support or oppose an HPV vaccine school-entry requirement is important for the policy processes to be successful. Education efforts must continue to change the HPV vaccine narrative. Messages should be crafted to educate and gain support among parents and stakeholders towards this population-based cancer prevention strategy.

Abstract
INTRODUCTION The human papillomavirus (HPV) increases the risk for cancers of the cervix, oropharynx, vulva, vagina, penis, and anus. HPV vaccination rates are low in many states having large medically underserved areas. In such areas, school nurses are a potential partner for improving population health, but their perceptions about HPV, HPV vaccination, and their role in promoting HPV vaccination have not been well documented. METHODS We administered a cross-sectional survey to 61 of 74 lead school nurses at their 2019 annual training session in South Carolina. Survey questions assessed lead school nurses' HPV vaccination beliefs, barriers, and HPV vaccination role in schools. We tabulated descriptive data and created heat maps to visualize correlations between responses. RESULTS Despite 95.1% of nurses envisioning a role in supporting HPV vaccination at their schools, only 41.0% envisioned an active role in promoting HPV vaccine among students. Lead nurses consistently believed in vaccinating both male and female students; in vaccine safety, effectiveness, and health benefits; and in recommending HPV vaccination. The nurses agreed that lack of time and competing priorities were barriers to HPV vaccination. Few other barriers were consistently identified. CONCLUSION Partnering with school nurses may be a feasible strategy to overcome barriers to increasing HPV vaccination rates in medically underserved areas. However, to increase nurses' confidence and time allotment to assume an active role in HPV vaccine promotion in their schools, coordinated and sustained partnerships between public health agencies, school districts, and school nurses are needed.

Abstract
INTRODUCTION Evidence has consistently shown the high efficacy of human papillomavirus (HPV) vaccines in preventing cervical cancers. However, the HPV vaccine uptake rate in Hong Kong is very low. We will develop and evaluate an innovative, theory-based multidisciplinary team-led school-based HPV vaccination health-promotion program (MDL-SHPVP), engaging female adolescents, parents/guardians, and secondary school personnel in multicomponent educational strategies and interactive discussions. METHODS AND ANALYSIS A cluster randomized controlled trial is proposed. We will recruit 2520 female adolescents and their parents/guardians from 18 secondary day schools. The MDL-SHPVP is underpinned by the Health Belief Model and Precaution Adoption Process Model. Multicomponent interventions will be offered, including education sessions with small group dialogues with a registered nurse and trained healthcare and lay volunteers, and educational computer games. A team of volunteers will be established to raise HPV, cervical cancer, and HPV vaccine awareness. Outcomes include adolescents' uptake of the HPV vaccine, adolescents' intention to receive HPV vaccination, vaccine acceptance among parents/guardians, and parents'/guardians' and adolescents' HPV knowledge, attitudes, and beliefs. Data will be collected at baseline, 1 month, and 1 year after intervention. The generalized estimating equations analysis will be used for comparing the outcomes between the 2 groups. ETHICS AND DISSEMINATION Ethical approval was obtained from the Joint Chinese University of Hong Kong-New Territories East Cluster Clinical Research Ethics Committee (Ref. no.: 2019.055). We will disseminate the study findings via peer-reviewed publications and presentations at relevant events and international and local conferences.

Abstract
Multilevel factors impact HPV vaccine series initiation and completion among adolescents in the U.S. Synthesis of these factors is needed to inform intervention development and to direct future research. Current frameworks synthesizing factors focus on females only and do not include both series initiation and completion outcomes. We conducted a systematic review of reviews to identify modifiable individual-, provider-, and clinic-level factors associated with HPV vaccination outcomes among U.S. adolescents and developed a multilevel framework illustrating relations between factors to inform intervention development. We searched Medline, PsychInfo, Pubmed, CINAHL, and ERIC databases and included reviews published 2006 to July 2, 2018 describing individual-, provider-, or clinic-level factors quantitatively associated with HPV vaccination among U.S. adolescents. Two coders independently screened reviews, extracted data, and determined quality ratings. Sixteen reviews containing 481 unique primary studies met criteria. Factors synthesized into the multilevel framework included parent psychosocial factors (knowledge, beliefs, outcome expectations, intentions) and behaviors, provider recommendation, and patient-targeted and provider-targeted clinic systems. The scope of our framework and review advances research in two key ways. First, the framework illustrates salient modifiable factors at multiple levels on which to intervene to increase HPV vaccination. Second, the review identified critical gaps in the literature at each level. Future research should link the body of literature on parental intentions to vaccination outcomes, identify provider psychosocial factors associated with recommendation behaviors and subsequent vaccine uptake in their patient population, and understand clinic factors associated with successful implementation of patient- and provider-targeted system-level interventions.

[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.

Abstract
School-local vaccination (SLV) has been a highly effective method of increasing rates of human papillomavirus (HPV) vaccination in many countries internationally in which vaccines are purchased by national, regional, or local public health authorities and offered free of charge within schools. However, the effectiveness of SLV for increasing HPV vaccination rates in the United States is likely to be substantially limited due to a number of identified barriers, the most significant of which is with the need to bill for vaccines among adolescents not covered under the Vaccines for Children Program. HPV vaccination within school-based health centers (SBHCs) has been much more effective than SLV, but SBHCs exist in only 2% of schools in the United States. The opportunity gap between the United States and other countries will remain unless reimbursement issues related to HPV delivery in schools can be addressed in a sustainable manner or SBHCs become much more common.

Abstract
BACKGROUND A strong recommendation from a clinician is one of the best predictors of human papillomavirus (HPV) vaccination among adolescents, yet many clinicians do not provide effective recommendations. The objective of this study was to understand how the lack of school entry requirements for HPV vaccination influences clinicians' recommendations. DESIGN AND METHODS Semi-structured interviews with a purposive sample of 32 clinicians were conducted in 2015 in Connecticut USA. Data were analysed using an iterative thematic approach in 2016-2017. RESULTS Many clinicians described presenting HPV vaccination as optional or non-urgent because it is not required for school entry. This was noted to be different from how other required vaccines were discussed. Even strong recommendations were often qualified by statements about the lack of requirements. Furthermore, lack of requirements was often raised initially by clinicians and not by parents. Many clinicians agreed that requirements would simplify the recommendation, but that parents may not agree with requirements. Personal opinions about school entry requirements were mixed. CONCLUSIONS The current lack of school entry requirements for HPV vaccination is an important influence on clinicians' recommendations that are often framed as optional or non-urgent. Efforts are needed to strengthen the quality of clinicians' recommendations in a way that remains strong and focused on disease prevention yet uncoupled from the lack of requirements that may encourage delays. Additionally, greater support for requirements among clinicians may be needed to successfully enact requirements in the future.

Abstract
BACKGROUND Countries with high human papillomavirus (HPV) vaccination rates have achieved this success largely through school-based vaccination. Using school-based health centers (SBHCs) in the United States, where HPV vaccine remains underutilized, could improve uptake. In this mixed-methods study, we examined acceptability, facilitators, and barriers of HPV vaccination visits at SBHCs from the perspectives of adolescents and parents. METHODS We conducted qualitative interviews and structured surveys with adolescents and parents recruited from an urban, hospital-based clinic. Interviews with parents (N = 20) and adolescents (N = 20) were audio-recorded and transcribed for analysis using an iterative thematic approach. Quantitative measures for a survey administered to parents (N = 131) were derived from the qualitative findings. Survey results were analyzed by chi-square tests. RESULTS Many participants expressed favorable opinions of HPV vaccination at SBHCs in qualitative interviews. Facilitators included convenience, ease of scheduling, and not missing work or school. However, barriers were noted including concerns about obtaining care outside the medical home, fragmentation of medical records, and negative perceptions about SBHCs. Quantitative findings revealed that a higher proportion of parents with experience using SBHCs were willing to use a middle school (59.5%) or high school (80.5%) SBHC for HPV vaccinations compared with those who had not used SBHCs (p < .05 for both comparisons). CONCLUSIONS HPV vaccination visits at SBHCs were acceptable, and SBHC users expressed more favorable attitudes. Barriers to HPV vaccination at SBHCs can be addressed through more education about SBHCs' role, and improvement of systems to coordinate care.
