Giving Boys a Shot: The HPV Vaccine's Portrayal in Canadian Newspapers

Awareness of human papillomavirus infection among Indigenous males in North America and Oceania: a Scoping Review

PURPOSE

Human papillomavirus (HPV) is the most commonly transmitted sexually transmitted infection. HPV infections have been on the rise among males, especially in the form of oropharyngeal cancer. Despite this, there is a gap in healthcare guidelines to increase HPV vaccine administration among males. In this study, we focus on the Indigenous population of North America and Oceania to determine existing barriers resulting in low HPV vaccination rates among the population.

METHOD

We surveyed peer-reviewed literature on the awareness of HPV infection among Indigenous males in North America and Oceania. Using keywords HPV plus male, men or boy, and ethnical filters such as Indigenous, Aboriginal or First Nations, we retrieved 54 articles based on titles, of which 15 were included after reading the abstracts.

RESULTS

Reported HPV awareness was generally low in Indigenous males in North America, with no peer-reviewed data from Oceania. The lower understanding by males compared to females was largely attributable to misconceptions about HPV-related diseases, their transmission, and prevention. Lack of awareness and concern toward the risk of contracting HPV infection in Indigenous males suggests an impediment in disseminating health information about this cancer-causing virus.

CONCLUSION

Culturally sensitive education, with emphasis on Indigenous males, is needed to improve this group's HPV knowledge. Researchers should also engage meaningfully with Indigenous communities by building rapport to achieve a positive change in attitude.

Disappearing Negative Valence: A Content Analysis of HPV Vaccine Newspaper Coverage in China (2000-2018)

News coverage of the human papillomavirus (HPV) vaccine grew rapidly in China in 2016 when the vaccine was approved. Drawing upon framing theory, the present study analyzed the content of 491 Chinese newspaper reports on the HPV vaccine published between June 2000 and December 2018 to investigate what and how information and valence about the vaccine was relayed to the public. The results indicated that, while the Chinese media failed to provide comprehensive and accurate information about HPV and the HPV vaccine, they showed a positive evaluation of the HPV vaccine demand and market. In addition, there was a decline in negative coverage after the vaccine was approved. This study extended the literature on HPV vaccine coverage by combining issue-specific framing and valence framing, considering the Chinese-specific vaccine market for presentation and the value of such products, which is rare in previous studies. Practical implications of the findings for health promotion were also discussed.

Get Vaccinated for Loved Ones: Effects of Self-Other Appeal and Message Framing in Promoting HPV Vaccination among Heterosexual Young Men

HPV has long been constructed as a sex-specific virus. Boys and men largely perceive the virus as not related to themselves and thus develop a female-specific schema on HPV. The present study investigates message strategies for promoting HPV vaccination among heterosexual young men in the United States. Through an online experiment, this study examined the effects of reference point (self, other, vs. self-other) and message framing (gain vs. loss) on processing fluency, optimistic bias, and behavioral intentions. The findings showed a schema-matching pattern in facilitating information processing, and a schema-mismatching pattern in attenuating optimistic bias. Specifically, other-referencing messages that related the outcomes of getting vaccinated for HPV to the message recipients' sexual partners promoted processing fluency and widened the self-other gap in perceived susceptibility to HPV, regardless of the message frame. By contrast, self-other-referencing messages that highlighted the outcomes regarding themselves and their sex partners enhanced processing fluency and mitigated optimistic bias. Moreover, the attenuation in optimistic bias increased the participants' information seeking intentions and the likelihood that they would share the messages on social media. The implications for health message design are discussed from a schema-based, message-tailoring perspective.

A review of ethical and legal aspects of gender-neutral human papillomavirus vaccination

While launching a campaign to eliminate cervical cancer, the World Health Organization called to halt human papillomavirus (HPV) gender-neutral vaccination (GNV) because of limited vaccine supply, raising ethical and legal questions about female-only vaccination versus GNV. We identified ethical and legal aspects of HPV GNV by searching MEDLINE for records up to February 19, 2021. We also provided an overview of HPV vaccines, the evolution of HPV vaccine recommendations in North America, and a timeline of male HPV vaccination introduction by searching PubMed, Google, and government websites. Four HPV vaccines are available: Cervarix®, Gardasil®, Gardasil®9, and Cecolin®. Vaccine recommendations in North America evolved from female only to eventually include males. Following the Food and Drug Administration's approval of the first HPV vaccine for males (2009), 35 countries began vaccinating males (2011-2020). Based on 56 eligible records out of 652, we identified the following constructs: lower male awareness of HPV and vaccination (n=13), limited economic resources (n=5), shared social responsibility (n=18), unprotected groups from female-only HPV vaccination (n=10), limited screening for HPV-associated noncervical cancers (n=6), consideration of ethical principles (n=17), and HPV vaccine mandates (n=5). Ethical and legal aspects must be considered when recommending vaccination for females only or GNV.

Barriers towards HPV Vaccinations for Boys and Young Men: A Narrative Review

Background: HPV vaccination of both girls and boys can protect against infection and eliminate the risk for HPV-associated cancer. Due to a common misconception that the virus only poses risks to women, vaccine coverage is suboptimal among men in many countries. It is urgent to identify barriers to vaccination of boys and men. Methods: We conducted a narrative review of publications examining attitudes and beliefs regarding HPV vaccination for boys and young men. The electronic databases searched were PubMed, PsychInfo and Scopus (December 2020; last update July 2021). A total of 103 original articles were included in the final analysis. Results: The central barriers against vaccination of boys and men are: (1) lack of knowledge, (2) vaccine hesitancy in general, (3) lack of recommendation from and/or discussions with healthcare providers, (4) cost and logistics, and (5) the idea that HPV vaccination may promote promiscuity. Men who have sex with men and families belonging to ethnic minorities express a need for information tailored to their situation. Conclusions: Boys should be included in national immunization programs and men should also be offered catch-up vaccinations. Future studies should focus on addressing vaccine hesitancy and developing interventions to promote pan-gender HPV vaccination.

When being positive might be negative: An analysis of Australian and New Zealand newspaper framing of vaccination post Australia's No Jab No Pay legislation

•

Positive frames of stories or statements are viewed by readers as persuasion.

•

People socially expect credible news media stories to be negatively framed.

•

Vaccine stories framed negatively may be deemed as more credible by readers.

•

Positively framed vaccination stories could be viewed as advertising or coercion.

Vaccination rates are an ongoing global concern. Many developing and developed countries have rates of vaccination below rates required for herd immunity, for differing reasons. One way in which to communicate information about vaccination to the wider public is via the use of the news media. Communication agenda-setting and framing theory generally hold that the news media sets the issues of importance to society and also tells us how we should think about those issues. Emphasis framing theory however, would suggest that positively-framed statements in the media may actually be viewed as persuasive in a coercing way, leading to resistance to the messages. Further, this theory claims that negative news media is viewed as more credible and therefore, more easily accepted. We were interested to explore the framing of news reports about vaccination and the potential effects this framing may have had on the wider public over the years 2016–2017 in both Australia and New Zealand (when changes in vaccination policy and publicity respectively were on the agenda). We undertook a content analysis of 197 articles and emphasis frame, type of message, and other variables recorded. In both Australia and New Zealand, the news media messages were predominately positively framed and yet the vaccination rates of New Zealand particularly (where no policy changes mandating vaccination took place) have been decreasing. We suggest the media emphasis on positive vaccination reporting may be having the opposite effect of engendering resistance to vaccination within those who are vaccine-hesitant.

Exploring the relationship between newspaper coverage of vaccines and childhood vaccination rates in Spain

Background: Despite the effectiveness of vaccines being well established and recognized by the research community, eleven European countries have adopted mandatory vaccination programs because of vaccine hesitancy. Lack of information and fake news are considered the main reasons. The media are a powerful tool for spreading vaccine-related information. The study of media effects on vaccine uptake has received little attention in Europe.Objective: To explore the association of childhood vaccination rates in Spain with vaccine-related coverage in print media.Methods: A content analysis of newspaper coverage of vaccines was conducted. The study variables were: national vaccination rates, article publication dates, tone and main theme of the articles. We conducted a correlation analysis to assess the association between media coverage and childhood vaccine uptake.Results: While vaccine coverage with positive and neutral tones significantly increased during the study period (p < .001), the number of articles with a negative tone remained unchanged (p = .306). There was a significant and inverse correlation between negative newspaper coverage and childhood vaccine uptake (r = -.771, p < .05). During 2016 and 2017, although the media reporting declined, vaccination rates kept increasing. The most frequent themes were about the development of the Ebola vaccine, and the chickenpox and meningitis vaccine crises.Conclusions: Our findings expand the understanding of media role on vaccination and suggest that the media need to be considered as an important player during vaccination campaigns. The study points to the important educational role of the media in public health.

The Use of Traditional Media for Public Communication about Medicines: A Systematic Review of Characteristics and Outcomes

A systematic review was conducted to identify, appraise, and synthesize data from original research investigating the use of traditional media for public communication about medicines. Databases were searched for studies conducting quantitative or qualitative analyses between the years 2007 and 2017. Data extraction and assessment of the quality of the resulting studies was conducted by one reviewer and checked for accuracy by a second reviewer. A total of 57 studies met the inclusion criteria. Studies were grouped as follows: "newspapers and other print media" (n = 42), "television" (n = 9), and "radio and a combination of media" (n = 6). Content analysis (n = 34) was the most frequent research design, followed by surveys or interviews (n = 14) and randomized controlled trials (RCTs) (n = 9). Advertising, public awareness, and health administration were the most common themes, and the medicines most analyzed were vaccines, particularly human papillomavirus (HPV) and influenza. Studies conducted in the United States were the most frequent, followed by other high-income countries such as Canada and the United Kingdom. The lack of consistent studies of the effects of media campaigns stresses the importance of the use of standardized research methodologies. Theoretical and practical implications of the findings for further research are discussed.

It's Complicated: The 2014-2015 U.S. Measles Outbreak and Parents' Vaccination Beliefs, Confidence, and Intentions

While it seems intuitive that highly visible vaccine-preventable disease outbreaks should impact perceptions of disease risk and facilitate vaccination, few empirical studies exist to confirm or dispel these beliefs. This study investigates the impact of the 2014-2015 Disneyland measles outbreak on parents' vaccination attitudes and future vaccination intentions. The analysis relies on a pair of public opinion surveys of American parents with at least one child under the age of six (N = 1,000 across each survey). Controlling for basic demographics, we found higher levels of reported confidence in the safety and efficacy of childhood vaccinations in our follow-up data collection. However, this confidence was also accompanied by elevated levels of concern toward childhood vaccines among American parents. We then examined how different subgroups in the population scored on these measures before and after the outbreak. We found that parents with high levels of interest in the topic of vaccines and a child who is not fully upto date with the recommended vaccination schedule reported more supportive attitudes toward vaccines. However, future intentions to follow the recommended vaccination schedule were not positively impacted by the outbreak. Possible explanations for these results and implications for vaccination outreach are discussed.

Inadequate and Incomplete: Chinese Newspapers' Coverage of the First Licensed Human Papillomavirus (HPV) Vaccine in China

Glaxo Smith Kline's Cervarix was the first human papillomavirus (HPV) vaccine licensed for use in China and officially launched there on 31 July 2017. Since news media content can influence people's vaccine-related knowledge, understanding, and intentions, a content analysis was used to examine Chinese newspapers' coverage of the HPV vaccine. A total of 253 articles published from 2000 to 2016 met the inclusion criteria and were coded. The results show that HPV and the HPV vaccine received very little newspaper coverage in China both before and after vaccine licensure. Most of the coverage came from China Party press newspapers, with the stories predominantly using thematic rather than episodic framing. Application of the Health Belief Model to the content analysis revealed that benefits, self-efficacy, and cues to action were found in most news stories. Overall, given the relative lack of Chinese newspaper coverage, public health officials and health-care providers in China should assume most people, including those for whom HPV vaccination is recommended, have little or no knowledge about HPV, HPV vaccine, and the reasons for the vaccination recommendation. If news media are to be a source of HPV information for the Chinese public, significant efforts will be needed to increase attention.

How is communication of vaccines in traditional media: a systematic review

AIM:

Taking into account that a key determinant in public approval of vaccinations is how the media constructs and frames messages about vaccination programmes, our aim is to review communication studies exploring media coverage of vaccines within traditional media venues.

METHODS:

Using a registered protocol (PROSPERO: 42017072849), a systematic review was conducted that searched in three international electronic databases (PubMed, Scopus, and the International Bibliography of Social Science) for articles published between 2007 and 2017 following content-analysis methods. The characteristics and outcomes were systematically identified and described. The search yielded 24 eligible studies that were further analysed in the review.

RESULTS:

Media coverage of vaccines has been largely studied during the last decade. Findings revealed that 62% ( n = 15) of studies analysed the human papillomavirus vaccine, 87% ( n = 21) examined newspapers, and 62% ( n = 15) examined North American media. In relation to media content analyses, 75% found negative messages on vaccines and 83% identified a lack of accurate information.

CONCLUSIONS:

This systematic review suggests an agenda for further research. There is a significant need to analyse other types of traditional media beyond newspapers. Future studies should focus on other geographical areas such as low-income countries and on analysing visual materials and digital media. We found that negative messages and inaccurate information are common in media coverage on vaccines; therefore, further research focusing on these topics is needed. Officials in public health organizations should develop a close collaboration with the media to improve public communication on vaccines.

[One decade of HPV vaccination in Germany]

As a worldwide very common sexually transmitted infection (STI), HPV causes millions of genital warts every year and is responsible for 5% of all cancers in men and women. With strong empirical evidence for both vaccine safety and efficacy, the HPV vaccines proved to protect against these HPV-related conditions over the last decade. But current HPV vaccination coverage is suboptimal in many countries. Even in Germany the absence of a school-based immunization program and the recommendation of a publicly funded girls-only HPV vaccination strategy are the main reasons for a female coverage rate under 40%, which does not achieve herd immunity for the boys. Therefore, the German immunization program urgently needs revision to fight an increasing number of young Germans missing out on the most important development in cancer prevention. Gender-neutral bundling of the HPV vaccine to other routinely recommended vaccines for preteens at one visit will have many advantages at the same time: Lowering the age of HPV vaccination to 9-12 years will improve the cost-effectiveness because a two-dose vaccination schedule is established on this score. Time-consuming and redundant explanations of the attending physician as well as parent's discussion on feeling stigmatized by the STI nature of HPV could be avoided in a combined vaccination setting. By expanding the HPV vaccination to boys, the resulting gender-neutral vaccination program can be cost-effective if all HPV-related diseases which can be prevented by vaccination are considered.

Comparing human papillomavirus vaccine concerns on Twitter: a cross-sectional study of users in Australia, Canada and the UK

OBJECTIVE

Opposition to human papillomavirus (HPV) vaccination is common on social media and has the potential to impact vaccine coverage. This study aims to conduct an international comparison of the proportions of tweets about HPV vaccines that express concerns, the types of concerns expressed and the social connections among users posting about HPV vaccines in Australia, Canada and the UK.

DESIGN

Using a cross-sectional design, an international comparison of English language tweets about HPV vaccines and social connections among Twitter users posting about HPV vaccines between January 2014 and April 2016 was conducted. The Health Belief Model, one of the most widely used theories in health psychology, was used as the basis for coding the types of HPV vaccine concerns expressed on Twitter.

SETTING

The content of tweets and the social connections between users who posted tweets about HPV vaccines from Australia, Canada and the UK.

POPULATION

16 789 Twitter users who posted 43 852 tweets about HPV vaccines.

MAIN OUTCOME MEASURES

The proportions of tweets expressing concern, the type of concern expressed and the proportions of local and international social connections between users.

RESULTS

Tweets expressing concerns about HPV vaccines made up 14.9% of tweets in Canada, 19.4% in Australia and 22.6% in the UK. The types of concerns expressed were similar across the three countries, with concerns related to 'perceived barriers' being the most common. Users expressing concerns about HPV vaccines in each of the three countries had a relatively high proportion of international followers also expressing concerns.

CONCLUSIONS

The proportions and types of HPV vaccine concerns expressed on Twitter were similar across the three countries. Twitter users who mostly expressed concerns about HPV vaccines were better connected to international users who shared their concerns compared with users who did not express concerns about HPV vaccines.

Human Papillomavirus Vaccination: What Are the Reasons for Nonvaccination Among U.S. Adolescents?

PURPOSE

Human papillomavirus (HPV) vaccination is recommended for 11- to 12-year-old U.S. adolescents. Unfortunately, HPV vaccine rates have been suboptimal. Parents are key decision agents regarding their adolescents' health; thus, it is necessary to understand their reasons for not vaccinating their adolescents. The purpose of this study was to compare parents' primary reasons for non-HPV vaccination by calendar year, sex of the child, and level of vaccine hesitancy.

METHODS

The National Immunization Survey-Teen 2012-2015 was subset to parents who did not intend for their adolescent to receive the HPV vaccine in the next 12 months (N = 59,897). Survey-weighted logistic regression models assessed the impact of year, sex, and level of hesitancy on main reasons for nonvaccination.

RESULTS

Not receiving a recommendation and lack of knowledge were significantly more likely to be the reasons for nonvaccination in 2012 and 2013 compared with 2015. The following reasons were significantly less likely to be reported for females compared with males: not recommended (odds ratio [OR] = .63, 95% confidence interval [CI], .58-.69) and lack of knowledge (OR = .86, 95% CI, .79-.94). In contrast, parents of females were more likely to state they were concerned about safety and side effects (OR = 2.19, 95% CI, 1.98-2.41). Differences in reasons for nonvaccination were observed between those who were unlikely and unsure regarding receiving the HPV vaccine.

CONCLUSIONS

Findings indicate that U.S. parental attitudes about HPV vaccination have changed over time and reasons for nonvaccination vary based on the sex of the adolescent and the level of hesitancy of the parent. This information can shape how providers respond to parental concerns and HPV vaccine hesitancy.

A Multiple Streams analysis of the decisions to fund gender-neutral HPV vaccination in Canada

In Canada, the human papillomavirus (HPV) vaccine is licensed and recommended for females and males. Although all Canadian jurisdictions fund school-based HPV vaccine programs for girls, only six jurisdictions fund school-based HPV vaccination for boys. The research aimed to analyze the factors that underpin government decisions to fund HPV vaccine for boys using a theoretical policy model, Kingdon's Multiple Streams framework. This approach assesses policy development by examining three concurrent, but independent, streams that guide analysis: Problem Stream, Policy Stream, and Politics Stream. Analysis from the Problem Stream highlights that males are affected by HPV-related diseases and are involved in transmitting HPV infection to their sexual partners. Policy Stream analysis makes clear that while the inclusion of males in HPV vaccine programs is suitable, equitable, and acceptable; there is debate regarding cost-effectiveness. Politics Stream analysis identifies the perspectives of six different stakeholder groups and highlights the contribution of government officials at the provincial and territorial level. Kingdon's Multiple Streams framework helps clarify the opportunities and barriers for HPV vaccine policy change. This analysis identified that the interpretation of cost-effectiveness models and advocacy of stakeholders such as citizen-advocates and HPV-affected politicians have been particularly important in galvanizing policy change.
