Abstract
Despite major advances in vaccination over the past century, resurgence of vaccine-preventable illnesses has led the World Health Organization to identify vaccine hesitancy as a major threat to global health. Vaccine hesitancy may be fueled by health information obtained from a variety of sources, including new media such as the Internet and social media platforms. As access to technology has improved, social media has attained global penetrance. In contrast to traditional media, social media allow individuals to rapidly create and share content globally without editorial oversight. Users may self-select content streams, contributing to ideological isolation. As such, there are considerable public health concerns raised by anti-vaccination messaging on such platforms and the consequent potential for downstream vaccine hesitancy, including the compromise of public confidence in future vaccine development for novel pathogens, such as SARS-CoV-2 for the prevention of COVID-19. In this review, we discuss the current position of social media platforms in propagating vaccine hesitancy and explore next steps in how social media may be used to improve health literacy and foster public trust in vaccination.

Abstract
BACKGROUND Though human papillomavirus (HPV) vaccination is a safe and effective method of protecting against associated cancers, uptake rates remain low among adolescents. Few studies have examined how social media use contributes to HPV-related knowledge gaps among parents and caregivers. OBJECTIVE To investigate the association between social media use and HPV-related awareness and knowledge with a focus on differences by gender and race/ethnicity among a nationally representative sample of adults with children in the household. METHODS We used data from the Health Information National Trends (HINTS) Survey (2017-2019) (N = 2,720). Multivariate logistic regressions were used to examine the association of social media use on HPV awareness and knowledge outcomes. RESULTS Compared to non-users, engaging in one, two, three, or four social media behaviors were associated with greater HPV awareness (aOR: 2.09; 95%CI: 1.18-3.70, aOR: 2.49; 95%CI: 1.40-4.42, aOR: 2.64; 95%CI: 1.15-6.05, and aOR: 2.44; 95%CI: 1.11-5.36, respectively). Increased social media use was associated with increased HPV vaccine awareness. Men, African American, Hispanic, and Asian American respondents were less likely to be aware of HPV or HPV vaccine. Social media use was not associated with cancer knowledge. CONCLUSIONS Increased social media use is associated with an increased awareness of HPV and HPV vaccine for adults with children in the household. Social media-based efforts can be utilized to increase knowledge of the benefits of HPV vaccination as cancer prevention, which may be a precursor to reducing HPV vaccine hesitancy and encouraging uptake to decrease cancer incidence rates among vulnerable populations.

Abstract
There is currently a lack of sufficient data on human papillomavirus (HPV)-attributable cervical carcinoma in China. Accordingly, we aimed to determine the prevalence and genotype distribution of HPV among women with cervical lesions in Shenzhen, in order to evaluate the potential benefit of HPV vaccination programs and inform cervical cancer control policies. We enrolled 5,255 patients who were admitted to the University of Chinese Academy of Sciences Shenzhen Hospital from January 2017 to December 2019. The HPV prevalence and genotype distribution were analyzed using the 21 HPV GenoArray diagnostic assay. A total of 937/5,255 patients showed HPV-positivity (prevalence rate 17.83%), of whom 85.81% (804/937) had high-risk HPV infection. HPV52 was the most prevalent genotype (4.72%, 248/5,255), followed by HPV58 (3.04%, 160/5,255), and HPV16 (2.72%, 143/5,255). The HPV prevalence rates among women with a normal cervix, low-grade intraepithelial lesions, high-grade intraepithelial lesions, invasive cervical cancer, and other characteristics were 15.63% (50/320), 58.65% (61/104), 80.00% (44/55), 88.57% (31/35), and 15.84% (751/4,741), respectively. HPV16, HPV18, and HPV52 accounted for the majority of cervical lesions, and the infection rates of HPV16 and HPV18 gradually increased with intraepithelial lesion progression (both P < .001). Our study found that HPV16, HPV52, and HPV18 played important roles in the occurrence and development of cervical lesions. This finding has the potential to guide the formulation of HPV screening and vaccination programs and preventive strategies for HPV-attributable cancer in this region.

Abstract
Due to social media's ability to publicize misinformation about vaccines, there is a need to study associations between social media engagement (SME) with human papillomavirus (HPV) and vaccine-related awareness and beliefs. Therefore, the study objectives were to (1) describe the SME of a nationally representative sample of US adults, and (2) determine the associations between SME and HPV-related awareness, HPV-related knowledge, HPV vaccine-related awareness, and perceived HPV vaccine efficacy. In 2019, we completed a secondary analysis of the 2017 Health Information National Trends Survey (Cycle 5.1). We created the SME index from 5 social media items. For each outcome variable, 3 models using binary and multinomial logistic regression were estimated. SME in the sample (n = 3171) was low (M = 0.9; range: 0-2). Respondents with higher SME had higher odds of HPV awareness (AOR = 1.56; 95% CI = 1.23, 1.99). Higher SME was associated with awareness of the HPV vaccine (AOR = 1.46; 95% CI = 1.16, 1.85). Respondents with higher SME had higher odds of perceiving HPV vaccine to be "not at all successful" (AOR = 2.22; 95% CI = 1.16, 4.24), "a little successful" (AOR = 1.99; 95% CI = 1.35, 2.94), "pretty successful" (AOR = 1.40; 95% CI = 1.04, 1.89), and "very successful" (AOR = 1.40; 95% CI = 1.02, 1.92) compared to those who selected "don't know" after adjusting for demographics and internet use. Our study highlights novel findings using a comprehensive SME index with a national sample providing insight to leverage existing consumer behaviors to better connect and disseminate accurate HPV information in a more strategic manner.

Abstract
BACKGROUND Social determinants of health explain most health inequities. Intermediate determinants dictate differences in the exposure and vulnerability of people based on social stratification. Vulnerable women (lower education level, older age, uninsured, etc.) have lower adherence to recommended Pap smear screening guidelines. However, a gap remains concerning the effect of social determinants on human papillomavirus (HPV) infection. OBJECTIVES The aim of this study was to analyze the association between the level of knowledge about HPV infection and HPV vaccines with education level and residential setting among a sample of Spanish women. METHODS A cross-sectional study at six primary care centers (Cantabria, Spain) was performed. All women >21 years consecutively attended by midwives for routine follow-up were invited to participate during the study period (2015-2016) until a convenience sample was recruited. Participants completed an anonymous questionnaire addressing sociodemographic variables (age, education level, and residential setting) and the level of knowledge regarding HPV infection, including general knowledge about infection and knowledge about the HPV vaccine. Associations between education level (primary, secondary, and university) and residential setting (urban, semiurban, and rural) with the level of knowledge of HPV infection and HPV vaccine were calculated using adjusted logistic regressions. Dose-response associations were estimated based on p-trend. RESULTS Compared to university women, a lower education level was associated with limited or no knowledge of either HPV infection or the HPV vaccine. Women living in rural areas poorly identified "promiscuity" as a risk factor of HPV infection and "the use of condoms" as a protective factor. Moreover, living in rural areas was associated with limited or no knowledge of HPV infection and HPV vaccine. There were significant dose-response trends; those who were more educated and living in more urban areas had more knowledge about either HPV infection or the vaccine. DISCUSSION In our sample, the level of knowledge of HPV infection and HPV vaccine was high. However, vulnerable women, defined by a lower education level and living in rural areas, presented a greater lack of knowledge regarding HPV infection and the HPV vaccine.

Abstract
OBJECTIVE To evaluate whether the social media strategy developed for the campaign Stop HPV - stop cervical cancer was successful at engaging target groups in communication regarding HPV vaccination. INTRODUCTION In 2009, the Human Papillomavirus (HPV) vaccine became part of the Danish childhood vaccination program to protect Danish girls from cervical cancer. In 2015, after a period of massive media coverage questioning the safety of the HPV vaccination, a rapid decline in HPV vaccination coverage was observed. An information campaign was therefore launched in May 2017 to address HPV vaccination hesitancy. THE SOCIAL MEDIA STRATEGY: 'Heart-brain communication' combined facts and emotions through varied content. Community management guidelines were worked out to ensure that there was positive dialogue. Key Point Indicators (KPI) for Engagement Rate (ER) and Click Through Rate (CTR) were chosen to uphold engagement and traffic from Facebook to the website. The KPIs were used to measure effectiveness. RESULTS In January 2019, the social media campaign had reached 8,020,000 people with an average of 127 comments per post. The average ER from May 2017 to halfway through 2018 was 6.07% and the CTR was 2.09%. The content subgroup personal stories was the most effective in creating positive dialogue. One year after the launch of the campaign, the number of positive comments had increased from less than 50% to approximately 75%. CONCLUSION A comprehensive social media strategy using 'heart-brain communication' proved useful in a campaign for HPV vaccination. The success of the social media strategy was due to meticulous planning prior to launching the campaign, the use of content subgroups, the allocation of adequate resources for community management, the empirical analysis of content, and the use of evaluation results as guidance for the production of new content.

Abstract
Background The World Health Organization recommends recording vaccination status according to maternal recall in countries where administrative reporting systems are insufficiently reliable, as maternal recall in developing countries has been shown to be quite reliable compared with data from vaccination cards. This study aimed to investigate childhood vaccination coverage and its determinants according to the mothers’ presentation of vaccination cards. Methods The data come from the 2017 Senegalese Demographic and Health Survey, a nationally representative household survey of women aged 15–49 years, with a questionnaire focusing on children’s health. This analysis was restricted to children aged 12–35 months (n = 4032) and it assessed vaccination coverage and associated sociodemographic factors with weighted multivariate logistic regressions. Stratified multivariate logistic regressions were also performed to investigate factors associated with routine childhood immunization uptake of the Bacillus Calmette-Guérin (BCG) vaccine, recommended for administration shortly after birth, as well as of the vaccines against yellow fever and measles (recommended at 9 months). Results Comparison of vaccination coverage estimates according to the vaccination card or parental recall resulted in a 5–10% difference in estimated coverage for the BCG, pentavalent, measles, and yellow fever vaccines, but a huge difference for the polio vaccine (93.0% with the card, 32.0% without it). Presentation of the vaccination card was correlated with mothers’ attendance at health facilities (suggesting it serves as a concrete manifestation of a bond between mothers and the healthcare system) and their region of residence, but it was not correlated with usually strong predictors of childhood vaccination, such as maternal education level. Factors associated with vaccinations differed depending on whether they were administered shortly after birth or later on. Conclusions Maternal recall was found to be quite reliable except for oral polio vaccination, which raises the possibility that complete immunization coverage rates could have been significantly underestimated due to potential confusion between injection and vaccination. Considering the ability to present vaccination cards as the materialization of a bond with the healthcare system, the decision path leading to vaccination among those who lack such a bond appears longer and more likely to be driven by supply-side effects.

Abstract
BACKGROUND AND OBJECTIVES Human papillomavirus (HPV) vaccination and cervical screening prevent cervical cancer effectively. However, there are concerns whether vaccination leads to high-risk sexual behaviors and less intention for cervical screening. We aimed to evaluate the influence of HPV vaccination on high-risk sexual behaviors, and intention for cervical screening among young Chinese females. We also reported the latest HPV vaccination uptake in Hong Kong. METHODS A population-based survey was conducted between September 2016 and January 2017. Subjects were school-age girls from twenty-five secondary schools (in-school) and community females between 18 and 27 years (out-school). Demographics, vaccine-related attitudes, intention for cervical screening and participants' sexual behaviors were examined. RESULTS We surveyed 2260 females from in-school (n = 1664) and out-school (n = 596) settings. 11.5% in-school and 23.5% out-school participants received at least one dose of HPV vaccine. Vaccination was not associated with age (in-school Odds Ratio [OR] 0.99, p = 0.87; out-school OR 1, p = 0.94), ethnicity (in-school OR 0.82, p = 0.72; out-school OR 0, p = 0.98), maternal education (in-school OR for secondary school 1.19, p = 0.43; for post-secondary school 1.28, p = 0.48), underage sex (in-school OR 1.22, p = 0.80; out-school OR 0.63, p = 0.67), earlier sexual exposure (in-school β 0.01, p = 0.99; out-school β 0.13, p = 0.68), multiple sex partners (in-school OR 3.27, p = 0.22; out-school OR 1.16, p = 0.43), and unprotected sex (in-school OR 1.14, p = 0.78; out-school OR 0.60, p = 0.10). Out-school females with higher personal education level was associated with higher vaccine uptake (post-secondary OR 3.4, p < 0.001; bachelor's degree or above OR 3.71, p < 0.001). More vaccinated females intended for cervical screening (in-school 23.6% vs. 21.1%; out-school 53.6% vs. 43.6%). Costs and knowledge were important factors for non-vaccination and non-intention for cervical screening. CONCLUSIONS HPV vaccination was not associated with earlier and high risk sexual behavior among Chinese young females. Vaccinated Chinese young females had a higher intention for cervical screening.

Social media and HPV vaccination: Unsolicited public comments on a Facebook post by the Western Cape Department of Health provide insights into determinants of vaccine hesitancy in South Africa. Vaccine 2019; 37:6317-6323. [PMID: 31521412 DOI: 10.1016/j.vaccine.2019.09.019] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2019] [Revised: 08/20/2019] [Accepted: 09/07/2019] [Indexed: 01/09/2023]
Abstract
On the 4 February 2019, the Western Cape Department of Health's Facebook page announced the implementation of a school-based vaccination campaign aimed to administer the first doses of human papillomavirus (HPV) vaccine in public schools to Grade 4 girls who are nine years old. This announcement was met with a flurry of social media responses posted on the campaign's Facebook page. This study identifies determinants of vaccine hesitancy amongst responses provided by social media users to this post. On 8 March 2019, we conducted a qualitative study including all 157 comments to the Facebook post. The post had 659 'emotion' reactions: 574 "likes", 62 "loves", 21 "angry faces", 2 "laughs", 2 "wows" and 1 "sad face". An overwhelming majority (636/659 i.e. 97%) of reactions were favourable to the HPV vaccination campaign. Out of the 157 comments, we judged 52 (33%) of them to be 'hesitant', suggesting that people with negative reactions though few in number, were more likely to be vocal deniers. Concern around the safety of HPV vaccines including effects on reproductive health was the most common theme identified. Other emerging themes included: risk of cervical cancer perceived as being low, issues around consent, concerns that girls are being used for research, questionable vaccine effectiveness, use of the school-based strategy for the campaign, risk-benefits calculations of HPV vaccination and constraints such as stock-outs. Knowing someone who had been affected or being at risk of cervical cancer, having knowledge about the causes of cervical cancer, confidence in the effectiveness and safety of the vaccine, knowing the vaccine was being used in high income settings, and having strong recommendations from the World Health Organisation and key actors seemed to increase the willingness to accept the vaccine. The magnitude and causes of HPV vaccine hesitancy need to be investigated to ensure the success of this programme.

Abstract
Social media has become a valuable tool for disseminating cancer prevention information. However, the design of messages for achieving wide dissemination remains poorly understood. We conducted a multi-method study to identify the effects of sender type (individuals or organizations) and content type (personal experiences or factual information) on promoting the spread of cervical cancer prevention messages over social media. First, we used observational Twitter data to examine correlations between sender type and content type with retweet activity. Then, to confirm the causal impact of message properties, we constructed 900 experimental tweets according to a 2 (sender type) by 2 (content type) factorial design and tested their probabilities of being shared in an online platform. A total of 782 female participants were randomly assigned to 87 independent 9-person online groups and each received a unique message feed of 100 tweets drawn from the 4 experimental cells over 5 days. We conducted both tweet-level and group-level analyses to examine the causal effects of tweet properties on influencing sharing behaviors. Personal experience tweets and organizational senders were associated with more retweets. However, the experimental study revealed that informational tweets were shared significantly more (19%, 95% CI: 11 to 27) than personal experience tweets; and organizational senders were shared significantly more (10%, 95% CI: 3 to 18) than individual senders. While rare personal experience messages can achieve large success, they are generally unsuccessful; however, there is a reproducible causal effect of messages that use organizational senders and factual information for achieving greater peer-to-peer dissemination.
