Pandemic effects on social capital in residents and non-residents of Chinese immigrant enclaves in Philadelphia.

The COVID-19 pandemic's effect on established Chinese ethnic enclaves, which faced socio-economic disruptions as well as anti-Asian sentiment, is unknown. We compared the pandemic's effect on social capital among residents and non-residents of Chinese ethnic enclaves in Philadelphia. Despite declines in group participation and citizenship activity (joining with others or speaking with local officials to address a neighborhood problem), the pandemic increased support received from other individuals and cognitive social capital (e.g., neighborhood trust and sense of belonging), with more pronounced changes in enclaves. Our findings provide evidence of both greater vulnerability and resilience in terms of social capital among Chinese immigrants during the pandemic. Understanding the pandemic's effects on social capital in different neighborhood contexts can underscore communities' strengths, and ways to improve resilience to future challenges.

"Cancer's a demon": a qualitative study of fear and multilevel factors contributing to cancer treatment delays.

PURPOSE: Delays initiating cancer therapy are increasingly common, impact outcomes, and have implications for health equity. However, it remains unclear (1) whether patients' beliefs regarding acceptable diagnostic to treatment intervals align with current guidelines, and (2) to what degree psychological factors contribute to longer intervals. We conducted a qualitative study with patients and cancer care team members ("providers"). METHODS: We interviewed patients with several common solid tumors as well as providers. Interviews were analyzed using an interpretive approach, guided by modified grounded theory. RESULTS: Twenty-two patients and 12 providers participated. Half of patients had breast cancer; 27% waited >60 days between diagnosis and treatment. Several themes emerged. (1) Patients felt treatment should begin immediately following diagnosis, while providers' opinion on the goal timeframe to start treatment varied. (2) Patients experienced psychological distress while waiting for treatment. (3) Participants identified logistical, social, and psychological sources of delay. Fear related to multiple aspects of cancer care was common. Emotion-driven barriers could manifest as not taking steps to move ahead, or as actions that delayed care. (4) Besides addressing logistical challenges, patients believed that education and anticipatory guidance, from their care team and from peers, may help overcome psychological barriers to treatment and facilitate the start of therapy. CONCLUSIONS: Patients feel an urgency to start cancer therapy, desiring time frames shorter than those included in guidelines. Psychological distress is frequently both a contributor to, and a consequence of, treatment delays. Addressing multilevel barriers, including psychological ones, may facilitate timely treatment and reduce distress.

Patient-Caregiver Portal System in Palliative Oncology: Assessment of Usability and Perceived Benefit.

BACKGROUND: The engagement of family caregivers in oncology is not universal or systematic. OBJECTIVE: We implemented a process intervention (ie, patient-caregiver portal system) with an existing patient portal system to (1) allow a patient to specify their caregiver and communication preferences with that caregiver, (2) connect the caregiver to a unique caregiver-specific portal page to indicate their needs, and (3) provide an electronic notification of the dyad's responses to the care team to inform clinicians and connect the caregiver to resources as needed. METHODS: We assessed usability and satisfaction with this patient-caregiver portal system among patients with cancer receiving palliative care, their caregivers, and clinicians. RESULTS: Of 31 consented patient-caregiver dyads, 20 patients and 19 caregivers logged in. Further, 60% (n=12) of patients indicated a preference to communicate equally or together with their caregiver. Caregivers reported high emotional (n=9, 47.3%), financial (n=6, 31.6%), and physical (n=6, 31.6%) caregiving-related strain. The care team received all patient-caregiver responses electronically. Most patients (86.6%, 13/15 who completed the user experience interview) and caregivers (94%, 16/17 who completed the user experience interview) were satisfied with the system, while, of the 6 participating clinicians, 66.7% agreed "quite a bit" (n=1, 16.7%) or "very much" (n=3, 50%) that the system allowed them to provide better care. CONCLUSIONS: Our findings demonstrate system usability, including a systematic way to identify caregiver needs and share with the care team in a way that is acceptable to patients and caregivers and perceived by clinicians to benefit clinical care. Integration of a patient-caregiver portal system may be an effective approach for systematically engaging caregivers. These findings highlight the need for additional research among caregivers of patients with less advanced cancer or with different illnesses.

Educating the next generation of cancer researchers: Evaluation of a cancer research partnership training program.

African American, American Indian and Alaska Native, Hispanic (or Latinx), Native Hawaiian, and other Pacific Islander groups are underrepresented in the biomedical workforce, which is one of the barriers to addressing cancer disparities among minority populations. The creation of a more inclusive biomedical workforce dedicated to reducing the burden of cancer health disparities requires structured, mentored research and cancer-related research exposure during the earlier stages of training. The Summer Cancer Research Institute (SCRI) is a multicomponent 8-week intensive summer program funded under the Partnership between a Minority Serving Institute and a National Institutes of Health-designated Comprehensive Cancer Center. In this survey study, we found that students who participated in the SCRI Program reported greater knowledge and interest in pursuing careers in cancer-related fields than their counterparts who did not participate in SCRI. Successes, challenges, and solutions in providing training in cancer and cancer health disparities research to improve diversity in the biomedical fields were also discussed.

Neighborhood gentrification, wealth, and co-ethnic density associations with acculturation stressors among Chinese immigrants.

Objective: This study examined the cross-sectional relationships between neighborhood social composition and gentrification, and acculturation stressors. Methods: Person-level data came from first-generation Chinese immigrants enrolled in the Immigrant Enclaves Study (Philadelphia, Pennsylvania, baseline 2018-2020, N = 512). A validated scale was used to assess 22 stressors associated with migration or acculturation. Neighborhood characteristics from the American Community Survey 2015-2019 and 2008-2012 included: tract proportion of foreign born Chinese, neighborhood wealth, and past decade gentrification. Most neighborhood exposures were modeled as continuous as well as binary variables (intended to represent highest level of neighborhood exposure). Multivariable negative binomial regression adjusted for age, gender, income, education, employment, language, years in the U.S., and neighborhood variables (proportion co-ethnic, and neighborhood per capita income). Results: The majority of participants spoke Mandarin (68% vs Cantonese 32%), mean participant age was 52.7 years old, years in the US was 18, and nearly one-half of the sample had less than 8 years of education. Mean number of stressors was 5.9 with nearly 20% of participants reporting 11 or more stressors. Multivariable results found the number of acculturation stressors was 18% lower for residents in the highest co-ethnic density neighborhoods and 13% lower for residents in the highest wealth areas, compared to other areas (expß 0.82, 95% CI [CI] 0.69, 0.98; expß 0.87, CI 0.75, 1.01, respectively). Stressors were no different whether participants lived in gentrified areas or not. Conclusions: Among middle-aged Chinese immigrants, acculturation stress was lower for residents in neighborhoods with higher proportion of Chinese immigrants and for residents in neighborhoods with higher wealth, whereas gentrification had no influence on acculturation stress. More work on this topic is needed with vulnerable populations such as this one, informed by local context.

Development of a Multilevel Model to Identify Patients at Risk for Delay in Starting Cancer Treatment.

Importance: Delays in starting cancer treatment disproportionately affect vulnerable populations and can influence patients' experience and outcomes. Machine learning algorithms incorporating electronic health record (EHR) data and neighborhood-level social determinants of health (SDOH) measures may identify at-risk patients. Objective: To develop and validate a machine learning model for estimating the probability of a treatment delay using multilevel data sources. Design, Setting, and Participants: This cohort study evaluated 4 different machine learning approaches for estimating the likelihood of a treatment delay greater than 60 days (group least absolute shrinkage and selection operator [LASSO], bayesian additive regression tree, gradient boosting, and random forest). Criteria for selecting between approaches were discrimination, calibration, and interpretability/simplicity. The multilevel data set included clinical, demographic, and neighborhood-level census data derived from the EHR, cancer registry, and American Community Survey. Patients with invasive breast, lung, colorectal, bladder, or kidney cancer diagnosed from 2013 to 2019 and treated at a comprehensive cancer center were included. Data analysis was performed from January 2022 to June 2023. Exposures: Variables included demographics, cancer characteristics, comorbidities, laboratory values, imaging orders, and neighborhood variables. Main Outcomes and Measures: The outcome estimated by machine learning models was likelihood of a delay greater than 60 days between cancer diagnosis and treatment initiation. The primary metric used to evaluate model performance was area under the receiver operating characteristic curve (AUC-ROC). Results: A total of 6409 patients were included (mean [SD] age, 62.8 [12.5] years; 4321 [67.4%] female; 2576 [40.2%] with breast cancer, 1738 [27.1%] with lung cancer, and 1059 [16.5%] with kidney cancer). A total of 1621 (25.3%) experienced a delay greater than 60 days. The selected group LASSO model had an AUC-ROC of 0.713 (95% CI, 0.679-0.745). Lower likelihood of delay was seen with diagnosis at the treating institution; first malignant neoplasm; Asian or Pacific Islander or White race; private insurance; and lacking comorbidities. Greater likelihood of delay was seen at the extremes of neighborhood deprivation. Model performance (AUC-ROC) was lower in Black patients, patients with race and ethnicity other than non-Hispanic White, and those living in the most disadvantaged neighborhoods. Though the model selected neighborhood SDOH variables as contributing variables, performance was similar when fit with and without these variables. Conclusions and Relevance: In this cohort study, a machine learning model incorporating EHR and SDOH data was able to estimate the likelihood of delays in starting cancer therapy. Future work should focus on additional ways to incorporate SDOH data to improve model performance, particularly in vulnerable populations.

Defining aggressive prostate cancer: a geospatial perspective.

BACKGROUND: Spatial analysis can identify communities where men are at risk for aggressive prostate cancer (PCan) and need intervention. However, there are several definitions for aggressive PCan. In this study, we evaluate geospatial patterns of 3 different aggressive PCan definitions in relation to PCan-specific mortality and provide methodologic and practical insights into how each definition may affect intervention targets. METHODS: Using the Pennsylvania State Cancer Registry data (2005-2015), we used 3 definitions to assign "aggressive" status to patients diagnosed with PCan. Definition one (D1, recently recommended as the primary definition, given high correlation with PCan death) was based on staging criteria T4/N1/M1 or Gleason score ≥ 8. Definition two (D2, most frequently-used definition in geospatial studies) included distant SEER summary stage. Definition three (D3) included Gleason score ≥ 7 only. Using Bayesian spatial models, we identified geographic clusters of elevated odds ratios for aggressive PCan (binomial model) for each definition and compared overlap between those clusters to clusters of elevated hazard ratios for PCan-specific mortality (Cox regression). RESULTS: The number of "aggressive" PCan cases varied by definition, and influenced quantity, location, and extent/size of geographic clusters in binomial models. While spatial patterns overlapped across all three definitions, using D2 in binomial models provided results most akin to PCan-specific mortality clusters as identified through Cox regression. This approach resulted in fewer clusters for targeted intervention and less sensitive to missing data compared to definitions that rely on clinical TNM staging. CONCLUSIONS: Using D2, based on distant SEER summary stage, in future research may facilitate consistency and allow for standardized comparison across geospatial studies.

Understanding the Challenges Faced by Esophageal and Gastroesophageal Junction Cancer Survivors.

The primary aim of this study is to characterize long-term quality of life (QOL) in patients with esophageal and gastroesophageal junction (EGEJ) cancers who underwent curative intent treatment. EGEJ survivors were recruited to participate in a one-time cross-sectional survey study using validated questionnaires assessing QOL. Chart review was conducted for patient demographics and clinical characteristics. Spearman correlation coefficients, Wilcoxon signed-rank test, and Fisher's exact test were used to assess relationships between patient characteristics and long-term outcomes. QOL was relatively high in this sample, as evidenced by high median scores on the functional scales and low median scores in the symptom domains of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30, with an overall median global health score of 75.0 (range 66.7-83.3). Patients using opiates at the time of survey reported lower role functioning (P = .004), social functioning (P = .052), and overall global health (P = .041). Younger patients had significantly higher rates of reflux (P = .019), odynophagia (P = .045), choking (P = .005), and cough (P = .007). Patients using opiates or of younger age had lower QOL and higher symptoms in this cohort of long-term EGEJ survivors.

Using Pointwise Mutual Information for Breast Cancer Health Disparities Research With SEER-Medicare Claims.

Identification of procedures using International Classification of Diseases or Healthcare Common Procedure Coding System codes is challenging when conducting medical claims research. We demonstrate how Pointwise Mutual Information can be used to find associated codes. We apply the method to an investigation of racial differences in breast cancer outcomes. We used Surveillance Epidemiology and End Results (SEER) data linked to Medicare claims. We identified treatment using two methods. First, we used previously published definitions. Second, we augmented definitions using codes empirically identified by the Pointwise Mutual Information statistic. Similar to previous findings, we found that presentation differences between Black and White women closed much of the estimated survival curve gap. However, we found that survival disparities were completely eliminated with the augmented treatment definitions. We were able to control for a wider range of treatment patterns that might affect survival differences between Black and White women with breast cancer.

Benefits versus drawbacks of delaying surgery due to additional consultations in older patients with breast cancer.

BACKGROUND: Additional evaluations, including second opinions, before breast cancer surgery may improve care, but may cause detrimental treatment delays that could allow disease progression. AIMS: We investigate the timing of surgical delays that are associated with survival benefits conferred by preoperative encounters versus the timing that are associated with potential harm. METHODS AND RESULTS: We investigated survival outcomes of SEER Medicare patients with stage 1-3 breast cancer using propensity score-based weighting. We examined interactions between the number of preoperative evaluation components and time from biopsy to definitive surgery. Components include new patient visits, unique surgeons, medical oncologists, or radiation oncologists consulted, established patient encounters, biopsies, and imaging studies. We identified 116 050 cases of whom 99% were female and had an average age of 75.0 (SD = 6.2). We found that new patient visits have a protective association with respect to breast cancer mortality if they occur quickly after diagnosis with breast cancer mortality subdistribution Hazard Ratios [sHRs] = 0.87 (95% Confidence Interval [CI] 0.76-1.00) for 2, 0.71 (CI 0.55-0.92) for 3, and 0.63 (CI 0.37-1.07) for 4+ visits at minimal delay. New patient visits predict worsened mortality compared with no visits if the surgical delay is greater than 33 days (CI 14-53) for 2, 33 days (CI 17-49) for 3, and 44 days (CI 12-75) for 4+. Medical oncologist visits predict worse outcomes if the surgical delay is greater than 29 days (CI 20-39) for 1 and 38 days (CI 12-65) for 2+ visits. Similarly, surgeon encounters switch from a positive to a negative association if the surgical delay exceeds 29 days (CI 17-41) for 1 visit, but the positive estimate persists over time for 3+ surgeon visits. CONCLUSION: Preoperative visits that cause substantial delays may be associated with increased mortality in older patients with breast cancer.

The psychometric properties of a caregiving-related strain scale in oncology.

BACKGROUND: Caregivers are rarely assessed for caregiving-related strain. This study explored the psychometric properties of the caregiving-related physical, emotional, and financial strain questions in the National Alliance for Caregiving's (NAC) survey and a new total score (NAC-3). METHODS: Comparisons were made to existing caregiver quality of life, distress, and burden instruments through an online, cross-sectional survey of U.S. adult cancer caregivers. RESULTS: Findings from 299 caregivers showed that the NAC-3 was moderately to strongly associated with each of the comparison instruments. Similar concepts were also shown to be more strongly correlated (except physical health construct) and dissimilar concepts items had weaker correlations. CONCLUSION: Findings suggest that the total score and individual items are psychometrically sound for use as compared to established caregiving-related instruments. The total score and items provide a concise option, potentially beneficial for clinical use, and can be compared to nationally representative samples of caregivers through NAC's surveys.

Empowering Low-Income Asian American Women to Conduct Human Papillomavirus Self-Sampling Test: A Community-Engaged and Culturally Tailored Intervention.

BACKGROUND: Asian American women face disproportionate burden of cervical cancer (CC) than non-Hispanic white women in the U.S. The goal of this study was to assess the feasibility and impact of a culturally tailored intervention to promote Human papillomavirus (HPV) self-sampling test among hard-to-reach Asian American women. METHODS: We adopted the community-based participatory research (CBPR) approach to conduct this efficacy study. A total of 156 female participants (56 Chinese, 50 Korean, and 50 Vietnamese) were recruited from community-based organizations (CBOs) in the greater Philadelphia metropolitan area. The intervention components included HPV-related education, HPV self-sampling test kit and instructions, group discussions, and patient navigations, all available in Asian languages. We examined several outcomes, including the completion of HPV self-sampling, HPV-related knowledge, perceived social support, self-efficacy, and comfort with the self-sampling test at post-intervention assessment. RESULTS: The majority of Asian American women had low annual household income (62.3% earned less than $20,000) and low educational attainment (61.3% without a college degree). We found significant increase in participants' knowledge on HPV (baseline: 2.83, post: 4.89, P <.001), social support (baseline: 3.91, post: 4.09, P < .001), self-efficacy (baseline: 3.05, post: 3.59, P < .001), and comfortable with HPV self-sample test (baseline: 3.62, post: 4.06, P < .001). CONCLUSION: To the best of our knowledge, this is the first intervention study that promoted HPV self-sampling test among Asian American women. Our findings showed that CBPR culturally tailored intervention of self-sampling was highly effective in empowering low-income Asian American women to conduct HPV self-sampling tests.

Systematic review of neighborhood socioeconomic indices studied across the cancer control continuum.

BACKGROUND: There is extensive interest in understanding how neighborhood socioeconomic status (nSES) may affect cancer incidence or survival. However, variability regarding items included and approaches used to form a composite nSES index presents challenges in summarizing overall associations with cancer. Given recent calls for standardized measures of neighborhood sociodemographic effects in cancer disparity research, the objective of this systematic review was to identify and compare existing nSES indices studied across the cancer continuum (incidence, screening, diagnosis, treatment, survival/mortality) and summarize associations by race/ethnicity and cancer site to inform future cancer disparity studies. METHODS: Using PRISMA guidelines, peer-reviewed articles published between 2010 and 2019 containing keywords related to nSES and cancer were identified in PubMed. RESULTS: Twenty-four nSES indices were identified from 75 studies. In general, findings indicated a significant association between nSES and cancer outcomes (n = 64/75 studies; 85.33%), with 42/64 (65.63%) adjusting for highly-correlated individual SES factors (e.g., education). However, the direction of association differed by cancer site, race/ethnicity, and nSES index. CONCLUSIONS: This review highlights several methodologic and conceptual issues surrounding nSES measurement and potential associations with cancer disparities. Recommendations pertaining to the selection of nSES measures are provided, which may help inform disparity-related disease processes and improve the identification of vulnerable populations in need of intervention.

Adverse Events Reported by Patients With Cancer After Administration of a 2-Dose mRNA COVID-19 Vaccine.

BACKGROUND: Most safety and efficacy trials of the SARS-CoV-2 vaccines excluded patients with cancer, yet these patients are more likely than healthy individuals to contract SARS-CoV-2 and more likely to become seriously ill after infection. Our objective was to record short-term adverse reactions to the COVID-19 vaccine in patients with cancer, to compare the magnitude and duration of these reactions with those of patients without cancer, and to determine whether adverse reactions are related to active cancer therapy. PATIENTS AND METHODS: A prospective, single-institution observational study was performed at an NCI-designated Comprehensive Cancer Center. All study participants received 2 doses of the Pfizer BNT162b2 vaccine separated by approximately 3 weeks. A report of adverse reactions to dose 1 of the vaccine was completed upon return to the clinic for dose 2. Participants completed an identical survey either online or by telephone 2 weeks after the second vaccine dose. RESULTS: The cohort of 1,753 patients included 67.5% who had a history of cancer and 12.0% who were receiving active cancer treatment. Local pain at the injection site was the most frequently reported symptom for all respondents and did not distinguish patients with cancer from those without cancer after either dose 1 (39.3% vs 43.9%; P=.07) or dose 2 (42.5% vs 40.3%; P=.45). Among patients with cancer, those receiving active treatment were less likely to report pain at the injection site after dose 1 compared with those not receiving active treatment (30.0% vs 41.4%; P=.002). The onset and duration of adverse events was otherwise unrelated to active cancer treatment. CONCLUSIONS: When patients with cancer were compared with those without cancer, few differences in reported adverse events were noted. Active cancer treatment had little impact on adverse event profiles.

A Telephone-Adapted Mindfulness-Based Stress Reduction Program: Preliminary Effects among Healthcare Employees.

Healthcare employees often experience high stress and may benefit from accessible psychosocial interventions. In this pilot study, we explored preliminary feasibility, acceptability, and psychological effects of a telephone-based adaption of mindfulness-based stress reduction (MBSR) for healthcare employees. Eleven participants (M age = 49.9; 27.3% ethnic/racial minority) were enrolled in an eight-session group-based MBSR program adapted for telephone delivery. Feasibility was assessed using rates of program attrition and session completion; acceptability was explored qualitatively via participants' responses to an open-ended item about their program experience. Participants also completed pre-and post-program assessments on psychosocial outcomes (distress (overall distress, depression, anxiety, somatization), mindfulness, and self-compassion). We characterized mean change scores, 95% confidence intervals, and effect sizes to explore preliminary program effects. With regard to preliminary feasibility, one participant dropped out prior to the intervention; of the remaining 10 participants, 90% completed at least half (≥4) of the sessions; 70% completed at least three-quarters (≥6 sessions). Feedback reflected positive experiences and included suggestions for program delivery. Participants reported reductions in distress post-program (M difference range = -5.0 to -9.4), showing medium to large effect sizes (d range = 0.68 to 1.11). Mindfulness scores increased from pre- to post-intervention (M difference range = 1.0 to 10.4), with small-to-medium effects (d range = 0.18 to 0.55). Almost all aspects of self-compassion remained stable over time, with the exception of common humanity, which increased post-program (M difference = 2.9, CI 95% 0.5 to 5.4, d = 0.91). Preliminary findings from our small pilot trial suggest that telephone-based adaptations of MBSR may be a useful mode of delivery for healthcare employees; however, larger studies are needed to provide further evidence of feasibility, acceptability, and program effects.

Ethnic density, social support, and loneliness among Chinese immigrants in Philadelphia.

Living in more 'ethnically dense' areas is thought to promote health, possibly by facilitating social support and a sense of belonging. Because of kin networks and cultural obligations, family relationships may be particularly important for Asian immigrants. Chinese-origin individuals are the largest group of Asian Americans and among the most highly segregated, but the psychosocial benefits of living in Chinese neighborhoods are not established. We examined whether Chinese immigrants in areas of higher ethnic density report more social support from family and friends, and less loneliness. For 606 participants recruited 1/2016-5/2019 throughout the Philadelphia region, residences were linked to American Community Survey 2013-2017 data. Ethnic density, operationalized as percent of Census tract residents who were Chinese, was categorized into quintiles. Family/friend support and loneliness were self-reported, then dichotomized to distinguish high levels of family support, friend support, and loneliness. In logistic regression adjusting for age, sex, and individual- and tract-level socioeconomic characteristics, ethnic density was associated with high family support (odds ratio (OR) 1.85, 95% confidence interval (CI) 1.09, 3.11) for highest vs. lowest ethnic density quintile)) and inversely associated with loneliness (OR 0.31, 95% CI 0.12, 0.79, highest vs. lowest quintile). Our findings support the hypothesis that residents of areas with higher ethnic density report more social support from family and less loneliness. Whether these benefits arise from characteristics of the community overall or from the aggregation of individual assets remains to be clarified but has implications for efforts to develop community resources that would benefit all their residents.

The role of trust in HPV vaccine uptake among racial and ethnic minorities in the United States: a narrative review.

Despite the clinically proven benefits of the human papillomavirus (HPV) vaccine in preventing cervical and other HPV-associated cancers, vaccination coverage has been suboptimal among adolescents and young adults in the United States (US), particularly among racial and ethnic minority adolescents. Historical legacies, combined with current racial/ethnic disparities in healthcare, may contribute to suboptimal uptake and completion of the HPV vaccine in part through differing levels of trust in doctors and healthcare institutions. The purpose of this narrative review was to characterize trust and its role in decision making about HPV vaccine uptake among US racial and ethnic minorities. We conducted a literature search using the PubMed database, and our search terms yielded 1176 articles. We reviewed 41 full-text articles for eligibility and included 20 articles in this review. These studies used varied measures of trust or mistrust and assessed trust in not only doctors/healthcare providers, but also other sources including pharmaceutical companies, media, and clergy. Our review findings revealed generally high levels of trust in doctors and healthcare providers, but less so in pharmaceutical companies. Mistrust of either healthcare providers, government agencies or pharmaceutical companies was consistently associated with less favorable attitudes and lower vaccine uptake. The downstream effects of mistrust may occur through selected health beliefs regarding the perceived efficacy and safety of the vaccine. Minority groups were more likely to report trust in family members, religious organizations, and media sources compared to their white counterparts. Decision making about vaccine uptake is a multilayered process that involves comparing the perceived benefits of the vaccine against its perceived risks. Understanding how trusted sources can effectively harness the tools of social and traditional media to increase knowledge and awareness may help combat misinformation about the HPV vaccine and improve engagement with diverse communities.
