Factors associated with latino sexual minority men's likelihood and motivation for obtaining a COVID-19 vaccine: a mixed-methods study

Perspectives of the COVID-19 pandemic and vaccination among racially and ethnically diverse gay, bisexual, and other men who have sex with men with and without HIV in the US South: findings from qualitative individual in-depth interviews

BACKGROUND

The impact of COVID-19 on specific populations, including gay, bisexual, and other men who have sex with men (GBMSM), varies based on a range of factors such as access to health care, underlying health behaviors and conditions, and social determinants of health. Our community-based participatory research partnership sought to better understand perspectives about and experiences with the COVID-19 pandemic, COVID-19 vaccination, and related health care among GBMSM.

METHODS

We collected, analyzed, and interpreted qualitative in-depth interview data from a diverse sample of GBMSM (N = 30) in North Carolina, USA. Using purposive sampling, we recruited native English (n = 15) and Spanish (n = 15) speakers and persons with HIV (n = 13) and persons without HIV (n = 17). We analyzed interview data using constant comparison, an approach to grounded theory.

RESULTS

Participant mean was 33.4 (SD = 8.5) years. Sixteen themes emerged that were categorized into five domains: trust/mistrust of politicians, healthcare professionals, and the US government (n = 4 themes); engagement in COVID-19 prevention strategies (n = 2 themes); attitudes towards COVID-19 vaccination (n = 3 themes); access to and use of health care (n = 4 themes); and impact of COVID-19 on social determinants of health and mental health (n = 3 themes).

CONCLUSIONS

This research increases our understanding of the COVID-19 pandemic among particularly minoritized and underserved communities: racially and ethnically diverse, English- and Spanish-speaking GBMSM with and without HIV in the US South. By addressing the unique needs and concerns of these communities, we can promote more equitable public health responses; enhance preventive healthcare delivery; improve preparedness for subsequent outbreaks (e.g., mpox), epidemics, and pandemics; and be better equipped to support delivery and uptake of potential future preventive HIV vaccines among communities impacted by health disparities.

Covid-19 Vaccine Hesitancy and Under-Vaccination among Marginalized Populations in the United States and Canada: A Scoping Review

BACKGROUND

Amid persistent disparities in Covid-19 vaccination and burgeoning research on vaccine hesitancy (VH), we conducted a scoping review to identify multilevel determinants of Covid-19 VH and under-vaccination among marginalized populations in the U.S. and Canada.

METHODS

Using the scoping review methodology developed by the Joanna Briggs Institute, we designed a search string and explored 7 databases to identify peer-reviewed articles published from January 1, 2020-October 25, 2022. We combine frequency analysis and narrative synthesis to describe factors influencing Covid-19 VH and under-vaccination among marginalized populations.

RESULTS

The search captured 11,374 non-duplicated records, scoped to 103 peer-reviewed articles. Among 14 marginalized populations identified, African American/Black, Latinx, LGBTQ+, American Indian/Indigenous, people with disabilities, and justice-involved people were the predominant focus. Thirty-two factors emerged as influencing Covid-19 VH, with structural racism/stigma and institutional mistrust (structural)(n = 71) most prevalent, followed by vaccine safety (vaccine-specific)(n = 62), side effects (vaccine-specific)(n = 50), trust in individual healthcare provider (social/community)(n = 38), and perceived risk of infection (individual)(n = 33). Structural factors predominated across populations, including structural racism/stigma and institutional mistrust, barriers to Covid-19 vaccine access due to limited supply/availability, distance/lack of transportation, no/low paid sick days, low internet/digital technology access, and lack of culturally- and linguistically-appropriate information.

DISCUSSION

We identified multilevel and complex drivers of Covid-19 under-vaccination among marginalized populations. Distinguishing vaccine-specific, individual, and social/community factors that may fuel decisional ambivalence, more appropriately defined as VH, from structural racism/structural stigma and systemic/institutional barriers to vaccination access may better support evidence-informed interventions to promote equity in access to vaccines and informed decision-making among marginalized populations.

Latino Sexual Minority Men's Pre-Exposure Prophylaxis Modality Preferences: A Latent Class Analysis

Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool available in several modalities (e.g., daily oral, injectable, implants, rectal douching). The Ending the HIV Epidemic (EHE) initiative, a national initiative that began in 2019 as a partnership among the Department of Health and Human Services and other federal agencies (e.g., the Centers for Disease Control and Prevention, National Institute of Health), seeks to increase PrEP engagement for groups experiencing HIV inequities, including Latino sexual minority men (LSMM). Given the limited research on PrEP modality preferences among LSMM, this study aimed to explore and characterize these preferences. LSMM (n = 214) not using PrEP and living in South Florida participated in the DÍMELO study, which examined PrEP engagement among LSMM in South Florida. Authors employed latent class analysis (LCA) to identify groups of LSMM based on their PrEP modality preferences and examined predictors of class membership. LCA results led to a three-class solution with participants who were: (1) reluctant to use most PrEP modalities (30.5%), (2) PrEP willing, with constraints (36.0%), and (3) enthusiastically accepting of all PrEP modalities (33.5%). LSMM in the reluctant class (Class 1) showed minimal interest in most PrEP modalities. The constrained class (Class 2) displayed interest in daily oral, on-demand, and quarterly injectable PrEP while the enthusiastic class (Class 3) demonstrated high interest in all modalities except rectal douching. Key predictors of PrEP modality preferences were altruism, community normalization of PrEP, and migration history. Understanding LSMM's PrEP modality preferences can enhance the reach of PrEP to LSMM, a group the EHE initiative prioritizes. The current findings suggest the need to tailor PrEP outreach efforts to promote various PrEP modalities based on LSMM's preferences.

"Going vaccine hunting": Multilevel influences on COVID-19 vaccination among racialized sexual and gender minority adults-a qualitative study

High levels of COVID-19 vaccine hesitancy have been reported among Black and Latinx populations, with lower vaccination coverage among racialized versus White sexual and gender minorities. We examined multilevel contexts that influence COVID-19 vaccine uptake, barriers to vaccination, and vaccine hesitancy among predominantly racialized sexual and gender minority individuals. Semi-structured online interviews explored perspectives and experiences around COVID-19 vaccination. Interviews were recorded, transcribed, uploaded into ATLAS.ti, and reviewed using thematic analysis. Among 40 participants (mean age, 29.0 years [SD, 9.6]), all identified as sexual and/or gender minority, 82.5% of whom were racialized. COVID-19 vaccination experiences were dominated by structural barriers: systemic racism, transphobia and homophobia in healthcare and government/public health institutions; limited availability of vaccination/appointments in vulnerable neighborhoods; absence of culturally-tailored and multi-language information; lack of digital/internet access; and prohibitive indirect costs of vaccination. Vaccine hesitancy reflected in uncertainties about a novel vaccine amid conflicting information and institutional mistrust was integrally linked to structural factors. Findings suggest that the uncritical application of "vaccine hesitancy" to unilaterally explain undervaccination among marginalized populations risks conflating structural and institutional barriers with individual-level psychological factors, in effect placing the onus on those most disenfranchised to overcome societal and institutional processes of marginalization. Rather, disaggregating structural determinants of vaccination availability, access, and institutional stigma and mistrust from individual attitudes and decision-making that reflect vaccine hesitancy, may support 1) evidence-informed interventions to mitigate structural barriers in access to vaccination, and 2) culturally-informed approaches to address decisional ambivalence in the context of structural homophobia, transphobia, and racism.

Factors associated with meningitis vaccine awareness and engagement among Latino men who have sex with men in South Florida

Awareness and uptake of the meningitis vaccine remains low among marginalized groups, such as Latino men who have sex with men (LMSM), potentially due to structural and psychosocial barriers in accessing preventative healthcare. The current study explored awareness and uptake of meningitis vaccines among a group of LMSM (N = 99) living in South Florida. A three-pronged variable selection approach was utilized prior to conducting regression models (linear and logistic). Overall, 48.5% of the participants reported little to no knowledge about meningitis vaccines, and 20.2% reported being vaccinated. Living with HIV (OR = 10.48) and time since outbreak (OR = 1.03) were significant predictors of meningitis vaccine uptake. No significant correlates of meningitis vaccine awareness were identified. More research is needed to identify other important factors associated with meningitis vaccine awareness and uptake among LMSM, a multiple marginalized group.

A Rapid Environmental Scan of South Florida HIV Organizations' Mpox Messaging During the August 2022 Peak of the U.S. Outbreak

The 2022 outbreak of mpox disproportionately impacted men who have sex with men and people living with HIV. As such, HIV organizations were uniquely situated to reach populations affected by mpox. However, the extent to which these organizations pivoted to address mpox, and what form mpox messaging took, is unknown. We conducted a rapid environmental scan of 29 HIV or sexual health organizations to assess the frequency and content of mpox messaging in August 2022, the peak of the mpox outbreak in Miami, FL. Approximately half of the organizations provided mpox messaging, most of which was accurate. Only 5% of the messages were in Spanish and 4% in Spanish and Haitian Creole. Our findings suggest HIV organizations' pivot to mpox messaging may have been delayed overall and in reaching Spanish- and Haitian Creole-speaking communities. Results could inform modifications to mpox messaging campaigns and future outbreaks that disproportionately affect minoritized communities.

Associations between the Self-Reported Likelihood of Receiving the COVID-19 Vaccine, Likelihood of Contracting COVID-19, Discrimination, and Anxiety/Depression by Sexual Orientation

There is limited evolving literature on COVID-19 vaccine uptake and its barriers among sexual minority populations (lesbian, gay, bisexual, transgender, and queer [LGBTQ]), despite their increased COVID-19 risk factors. We assessed the differences in intention to receive the COVID-19 vaccine by self-reported likelihood of contracting COVID-19, anxiety/depression, discrimination frequency, social distancing stress, and sociodemographic factors across sexual orientation. An online national cross-sectional survey was conducted in the United States between 13 May 2021, and 9 January 2022, among adults aged ≥18 (n = 5404). Sexual minority individuals had a lower intention of receiving the COVID-19 vaccine (65.62%) than heterosexual individuals (67.56%). Disaggregation by sexual orientation, however, showed that gay participants had a higher intention of COVID-19 vaccination (80.41%) and lesbian (62.63%), bisexual (64.08%), and non-heterosexual, non-LGB sexual minority (56.34%) respondents had lower intentions of receiving the COVID-19 vaccine than heterosexual respondents. Sexual orientation significantly moderated the association between the perceived likelihood of receiving the COVID-19 vaccine and the self-reported likelihood of contracting COVID-19, anxiety/depression symptoms, and discrimination. Our findings further underline the importance of improving vaccination efforts and access among sexual minority individuals and other vulnerable groups.

Broad perspectives in understanding vaccine hesitancy and vaccine confidence: an introduction to the special issue

The World Health Organization has designated vaccine hesitancy and vaccine confidence among the most pressing issues in global health. The COVID-19 pandemic has made vaccine hesitancy and vaccine confidence particularly salient and urgent. The purpose of this special issue is to highlight a broad range of perspectives on these critical issues. We have included a total of 30 papers that address issues related to vaccine hesitancy and vaccine confidence across multiple levels of the Socio-Ecological Model. We have organized the empirical papers into the following sections: individual-level beliefs, minority health and health disparities, social media and conspiracy beliefs, and interventions. In addition to the empirical papers, three commentaries are included in this special issue.

Structural Life Instability and Factors Related to Latino Sexual Minority Men's Intention to Engage with Biomedical HIV-Prevention Services

Latino sexual minority men (LSMM) experience high rates of HIV and co-occurring health inequities. Structural and psychosocial factors may lead to mental health problems and decreased engagement with biomedical HIV-prevention behaviors. This cross-sectional study assessed the extent to which structural life instability is related to biomedical HIV-prevention services engagement (HIV-testing and PrEP uptake) indirectly through psychological distress among 290 LSMM living in Greater Miami. Using hybrid structural equation modeling, significant direct effects from structural life instability to psychological distress emerged, as did effects from psychological distress (i.e., depression and anxiety) to HIV-prevention engagement. Structural life instability had a significant indirect effect to HIV-prevention engagement via psychological distress. Findings show a possible mechanism explaining the relationship between structural life instability and biomedical HIV-prevention engagement among a group of LSMM, a subpopulation at increased susceptibility for HIV acquisition in an U.S. HIV epicenter.

Factors Associated with Post-Exposure Prophylaxis Awareness Among Latino Sexual Minority Men in South Florida

Despite their efficacy, biomedical HIV prevention tools such as post-exposure prophylaxis (PEP) and pre-exposure prophylaxis (PrEP) have been insufficiently scaled up and disseminated, especially among marginalized subgroups that face substantial HIV disparities. Given the minimal literature available on PEP among Latino sexual minority men (LSMM), this cross-sectional secondary analysis explored factors associated with PEP awareness among a group of LSMM living in South Florida, a US HIV epicenter. The parent study examined patterns of engagement in PrEP and behavioral health treatment services among LSMM (N = 290). The current secondary analysis (N = 243) identified factors associated with PEP awareness using three methods: stochastic search variable selection, participatory data science, and literature review-before being modeled using linear regression. Most participants (67.5%) reported having little to no awareness about PEP before initiating our study. Simple linear regression models suggested that higher PrEP knowledge (B = 0.17, SE = 0.02, p < 0.001), HIV knowledge (B = 0.15, SE = 0.04, p < 0.001), PrEP self-efficacy (B = 0.37, SE = 0.13, p < 0.05), and high perceived community norms for HIV testing (B = 0.29, SE = 0.14, p < 0.05) were each associated with LSMM's greater PEP awareness, while identity affirmation was associated with less PEP awareness (B = -0.13, SE = 0.05, p < 0.01). Results suggest the utility of our three-pronged variable selection approach and address gaps in PEP awareness and use among LSMM living in a US HIV epicenter to support Ending the HIV Epidemic goals.

Intersectional Immunity? Examining How Race/Ethnicity and Sexual Orientation Combine to Shape Influenza Vaccination Among US Adults

Influenza vaccination is a critical preventive healthcare behavior designed to prevent spread of seasonal flu. This paper contributes to existing scholarship by applying an intersectional perspective to examine how influenza vaccination differs across specific intersections of racial/ethnic and sexual identity. Drawing on aggregated state-level data from Behavioral Risk Factor Surveillance System (BRFSS) from 2011 to 2020, I examine how flu vaccination differs across 18 racial/ethnic-by-sexual orientation groups (N = 1,986,432). Findings from descriptive analyses and logistic regression modeling demonstrate three key findings. First, it corroborates previous studies of vaccination, finding lower rates of flu vaccination among black adults relative to whites; gays/lesbians vaccinate at higher rates than heterosexuals and bisexuals, with bisexuals reporting lower vaccination relative to both heterosexuals and gays/lesbians. Second, it demonstrates how sexual orientation complicates established patterns between race/ethnicity and vaccination (e.g., influenza vaccination is more racially stratified among heterosexuals, with patterns more variable among gays/lesbians) and how race/ethnicity complicates previous patterns of vaccination by sexual orientation (e.g., Asian bisexuals vaccinate more than both heterosexuals). Third, findings pinpoint identities (e.g., black heterosexuals relative to their white peers and white bisexuals relative to their gay/lesbian peers) most in need of influenza vaccination outreach efforts. Implications for findings suggest that heterosexuals, especially black, may be less likely to vaccinate against influenza thus may need more encouragement from clinicians to vaccinate. Additionally, influenza vaccination should be free for all persons to lessen the barrier of access for this preventative healthcare.

Using a cloud-based machine-learning classification tree analysis to understand the demographic characteristics associated with COVID-19 booster vaccination among adults in the United States

A tree model identified adults age ≤34 years, Johnson & Johnson primary series recipients, people from racial/ethnic minority groups, residents of nonlarge metro areas, and those living in socially vulnerable communities in the South as less likely to be boosted. These findings can guide clinical/public health outreach toward specific subpopulations.
