METHODS: A total of 207 of the 318 Black participants (65%) in the RAND American Life Panel, a nationally representative internet panel, were surveyed about COVID-19 vaccine intentions in November-December 2020. Participants’ census tracts were geocoded using the Centers for Disease Control and Prevention's Social Vulnerability Index. RESULTS: Overall, 35% agreed or strongly agreed that they would not get a COVID-19 vaccine, 40% agreed or strongly agreed that they would get vaccinated, and 25% reported “don't know.” Significant multivariable predictors of not wanting to get vaccinated included high mistrust of the vaccine itself (e.g., concerns about harm and side effects), OR (95% CI) = 2.2 (1.2–3.9), p = .007, and weak subjective norms for vaccination in one's close social network, OR (95% CI) = 0.6 (0.4–0.7), p < .001. Residence in an area of higher socioeconomic vulnerability was a marginally significant predictor, OR (95% CI) = 3.1 (0.9–11.0), p = .08. CONCLUSIONS: High mistrust around COVID-19 vaccines may lower vaccine confidence. Social network members’ attitudes can be influential in encouraging vaccination. Public health communications could use transparent and clear messaging on safety and efficacy, and acknowledge historical and ongoing discrimination and racism as understandable reasons for low confidence in COVID-19 vaccines. Future research is needed to consider vaccine access challenges in tandem with mistrust as contributing to low vaccination rates across health conditions. lack Americans show large COVID-19 disparities in diagnoses, hospitalizations, and mortality rates. As of late April 2021, Black Americans were 1.1 times more likely than non-Hispanic Whites to be diagnosed with COVID-19, were 2.8 times more likely to be hospitalized, and had a 1.9 times higher mortality rate. 1 Systemic inequities in social vulnerability, including higher poverty levels, lower-wage employment (e.g., as low-wage essential workers), and unstable and crowded living conditions, have led to these disparities. [2] [3] [4] [5] [6] Social vulnerability also is associated with higher prevalences of underlying health conditions (e.g., diabetes, obesity, chronic obstructive pulmonary disease) associated with severe COVID-19 disease and death. 7 , 8 COVID-19 related inequities may be further exacerbated by lower vaccination rates among Black Americans. Soon after the November 2020 announcements by pharmaceutical companies (Pfizer-BioNTech and Moderna) about their vaccines' high efficacy, polls showed that Black Americans were less willing than individuals of other races/ethnicities to be vaccinated for COVID-19. For example, a December 2020 nationally representative telephone poll found that 35% of Black adults said they would definitely or probably not get vaccinated 9 -and mistrust of vaccines and worry about COVID-19 infection from the vaccine were listed as main reasons for not wanting to get vaccinated by about half of the Black Americans in the sample who showed low vaccine intentions. A November 2020 online survey found that 42% of Black Americans, versus 63% of Hispanic/Latinx and 61% of White adults, said they would definitely or probably get vaccinated-and by March 2021, these percentages substantially increased, although disparities persisted-with 61% of Black Americans vs. 70% of Hispanic/Latinx and 69% of White adults willing to be vaccinated or already vaccinated. 10 However, despite growing vaccine confidence, Black Americans have been disproportionately less likely to be vaccinated than non-Hispanic White Americans, which is a consequence of racial and ethnic inequities in access as well as low confidence in the vaccines. [11] [12] [13] Multiple factors determine vaccine confidence, including the perceived value of vaccination (self-perceived risk of infection), access to vaccination (availability and affordability), and trust in the vaccine itself (i.e., in its effectiveness and safety), in healthcare systems, healthcare providers, and policymakers who support the vaccine, and in those involved in vaccine development (e.g. the pharmaceutical industry). 14 Limited research has specifically focused on determinants of vaccine confidence among Black individuals. Medical mistrust (defined as distrust of the healthcare system, providers, and treatments 15 , 16 ) may be contributing to vaccine confidence among Black Americans. Medical mistrust has been conceptualized as an understandable, rational, self-protective response to historical and ongoing structural and interpersonal discrimination and racism in healthcare, and lack of trustworthiness of healthcare systems and institutions in U.S. society. 15 , 17-20 Thus, medical mistrust may lead to avoidance of healthcare, including of vaccination, among Black Americans. Because vaccine confidence may vary by context, time, and population, it is important to understand contributors to COVID-19 intentions for Black Americans in particular, to enable the tailoring of policy approaches by the community. Thus, we conducted an analysis of vaccine intentions in a nationally representative sample of Black Americans. We examined the extent to which socio-demographic and health-related background characteristics, medical mistrust, the perceived need for vaccination, confidence in vaccine efficacy and safety, social norms for vaccination, and neighborhood-level social vulnerability factors were associated with intentions to get vaccinated for COVID-19. We conducted a web-based survey of Black Americans, starting on November 17, 2020 (about a week after public announcements by Pfizer-BioNTech and Moderna about their vaccines' high efficacy) and ending on December 2, 2020. Participants were drawn from the RAND American Life Panel (ALP), a nationally representative internet panel. All 318 self-identified Black participants in the ALP were invited to participate, and 207 completed the survey (a 65% completion rate). Participants provided online informed consent after the nature and possible consequences of the study were fully explained, and received a $17 incentive for the 25 min survey (the standard rate for the ALP panel). Full details of the ALP's methodology are available in a prior report. 21 The survey contained items that were developed for the study or adapted from prior research, as described below. Participants were asked two questions to assess negative and positive vaccine intentions, respectively: 18 "If a vaccine were available to prevent COVID-19, I would not get it," with response options strongly disagree , disagree , don't know , agree , and strongly agree (dichotomized as strongly disagree or disag ree vs. don't know, ag ree, or strongly agree); and, "Would you be willing to get a COVID-19 vaccine when it becomes available?' with response options yes , no , and don't know/not sure (dichotomized as yes vs. no or don't know/not sure). Two questions were asked in order to assess whether levels and correlates of vaccine intentions differed by question methodology (i.e., asking whether one would not get vaccinated vs. one's willingness to get vaccinated). Socio-demographic and background characteristics. Socio-demographic characteristics were linked to the present study dataset from the My Household ALP survey (fielded starting October 15, 2020) and included age, gender, race, ethnicity, being U.S. born, marital status, employment status, educational level, household income, and occupational category (on a checklist; dichotomized as healthcare practitioner and technical occupations and healthcare support occupations vs. non-healthcare worker occupation ). Questions were added on sexual identity ( straight or heterosexual ; gay , homosexual, or same gender loving ; bisexual, pansexual, or other non-monosexual identity ; queer ; questioning, not sure, or in transition ; something else ; or don't know ) and gender identity ( transgender male to female , transgender female to male , gender non-conforming , or not transgender ). We also adapted the Epidemic-Pandemic Impacts Inventory 22 to assess 13 social, economic, and health consequences of COVID-19 (e.g., job loss, food insecurity), from which a summary score was derived. Vaccine confidence and mistrust beliefs. Confidenceand mistrust-related beliefs around the vaccine were assessed with items from prior research (see Table 1 ) , 18 , 19 , 23-26 including perceived need for COVID-19 vaccination, perceived ease of vaccine access, and confidence in vaccine effectiveness and safety, as well as vaccine-related mistr ust. Mistr ust was measured as a multi-faceted construct encompassing distrust of the vaccine itself, in the government, and in health care providers and institutions that provide information about and offer the vaccine-and included perceptions of racial equity in healthcare (i.e., race-based medical mistrust). Response options for all items were strongly disagree , disagree , don't know , agree , and strongly agree . Social norms around COVID-19 vaccination. Social norms items were adapted from prior research. 27 , 28 Subjective social norms items (i.e., social pressure from oth- ers such as friends and family) included "How important do you think your friends [family members] think it is to get a COVID-19 vaccine?" on a scale from 0, not at all important , to 100, extremely important ; and "Of the people close to you, what proportion of them would want you to get the COVID-19 vaccine?" on a scale from 1 = few (0-20%) to 5 = most or nearly all (81-100%) . Perceived descriptive social norms (i.e., the extent to which others would get vaccinated) included, "How many people in the U.S. [of your own race] do you think will get the COVID-19 vaccine when it becomes available?" on a scale from 1 = few (0-20%) to 5 = most or nearly all (81-100%) . Neighborhood-level variables. We derived the CDC's Social Vulnerability Indices (overall index and four subcomponents) for each participant's census tract using 15 census variables (e.g., poverty, crowded housing) that measure "potential negative effects on communities caused by external stresses on human health." 29 The four social vulnerability sub-components are: socioeconomic status; household composition and disability; minority status and language; and housing type and transportation. We also linked the survey data to the urban/rural residency variable measured in the ALP. Exploratory factor analysis. We conducted an exploratory factor analysis using varimax rotation 30 on the 27 items that represented the conceptual components of vaccine confidence and mistrust, shown in Table 1 . Based on an eigenvalue minimum value criterion of 1, four factors were extracted and four subscales were created, retaining items with factor loadings of > 0.40. The four subscales were: confidence and need ( α = 0.90); mistrust of the COVID-19 vaccine ( α = 0.73); mistrust of the government around COVID-19 information and intentions ( α = 0.83); and race-based medical mistrust around COVID-19 ( α = 0.70). Final scale items and their descriptive statistics are shown in Table 1 . The four subscales were significantly correlated with each other: COVID-19 vaccine mistrust with the confidence and need subscale ( r = −0.46), the government mistrust subscale ( r = 0.48), and the race-based mistrust subscale ( r = 0.30); the confidence and need subscale with the gover nment mistr ust subscale ( r = −0.35) and the racebased mistrust subscale ( r = −0.29); and the government mistrust subscale with the race-based mistrust subscale ( r = 0.42) (all p < 0.05). Logistic regressions. We conducted bivariate and multivariable logistic regressions predicting lack of intention to get vaccinated (0 = strongly disagree/disagree vs. 1 = strongly agree/agree or don't know , that they would not get vaccinated) and willingness to get vaccinated (1 = yes vs. 0 = no or don't know/not sure , that they would be willing to get a COVID-19 vaccine), in separate models. Because of the large number of potential predictors (and inadequate statistical power to examine all of them simultaneously), in the multivariable logistic regression analyses, we examined independent variables in four separate conceptually distinct sets, predicting negative and positive vaccine intentions using (1) socio-demographic and background characteristics; (2) individual-level vaccine confidence and mistrust beliefs (confidence and need subscale, mistrust subscales); (3) perceived social norms; and (4) neighborhood-level variables that were significant at p < .05 in the bivariate models. We then conducted a final regression that included all significant variables (at p < .05) from the four regressions for each outcome. Design weights were employed in all analyses to be representative of the national population of Black and African American adults. The weighting algorithm included highest educational level, age, and family income by the number of household members. Due to small cell sample sizes for gender (when gender was crossed with these variables), gender was not included in the weighting algorithm. Participant characteristics. Participants were diverse demographically (see Table 2 ): They were 50.8 years old on average (SD = 12.7, Range = 25-86 years); 71% selfidentified as female, 37% were married, and 6% were Latinx. About 14% identified as a sexual or gender minority. Most (91%) were born in the U.S. and resided in urban areas (93%). Half (50%) were not currently employed, about a quarter (23%) had a high school degree or less, and about half (48%) reported less than $40,000 annual household income. As compared to the national population of Black and African Americans, participants were older on average, and a higher percentage were female and from the U.S. Middle-Atlantic and Pacific regions (with a lower percentage from Southern regions); these differences may be a consequence of the relatively low sample size. Overall, over a third had low intentions to get vaccinated (11.4% agreed and 23.5% strongly agreed that they would not get a COVID-19 vaccine), and an additional 25.2% said "don't know"; only two-fifths agreed (21.6%) or strongly agreed (18.4%) that they would get vaccinated. In addition, 30.4% said that they were willing to get vaccinated for COVID-19, 31.6% said that they were not willing to get vaccinated, and 37.9% said "don't know/not sure." Bivariate and multivariable predictors of vaccine intentions. Bivariate analyses are presented in Table 3 , and multivariable analyses are presented in Tables 4 and 5 . Socio-demographic and background characteristics. In bivariate tests, participants who self-identified as female and who were employed in a healthcare-related occupa-tion were more likely to say that they would not get vaccinated, compared to those who were male and who were not employed in a healthcare-related occupation; these factors were reduced to marginal significance in the multivariable model of the socio-demographic and background characteristics block. Furthermore, partici- pants who were older, self-identified as male, and experienced a lower number of negative consequences from COVID-19 showed greater willingness to get vaccinated than those who were younger, female, and did not experience as many negative consequences; except for age, these factors remained significant in the multivariable model of the socio-demographic and background characteristics block. Vaccine confidence and mistrust beliefs. Bivariate tests indicated that participants who mistrusted the COVID-19 vaccine itself, who mistrusted the government around COVID-19, and who held weaker confidence in the COVID-19 vaccine, were more likely to say that they would not get vaccinated. In contrast, participants who had g reater tr ust in the vaccine, in healthcare providers, and in the government around COVID-19, as well as stronger confidence in the vaccine, were more willing to get vaccinated, and those who had higher levels of race-based mistrust were less willing to get vaccinated. The multivariable models for these vaccine beliefs indicated that greater mistrust of and lower confidence in COVID-19 vaccines were associated with lower vaccine intentions for both outcomes; additionally, mistrust in the government around COVID-19 information was marginally associated with lower willingness to get vaccinated. Perceived social norms. In bivariate models, participants who had lower subjective and descriptive norms for COVID-19 vaccination showed lower vaccine intentions for both outcomes. In the multivariable model for the social norms block for negative intentions, the only remaining significant predictor was perceived subjective norms for "people close to you" wanting one to get vaccinated; for positive intentions, both perceived subjective norms for "people of your own race" and "people close to you" remained significant. Neighborhood-level variables. Bivariate models showed that participants who resided in areas of greater social vulnerability overall, and of greater social vulnerability related to socio-economic status, showed lower vaccine intentions for both outcomes. Because the overall and socio-economic social vulnerability variables were highly correlated ( r = 0.94), and because socio-economic vulnerability showed the largest effects, only the socioeconomic vulnerability sub-component was included in multivariable analyses going forward. Final multivariable predictors of vaccine intentions. As shown in Table 4 , for the outcome of negative vaccine intentions, the final model combining all significant predictors from the four regressions of each conceptual grouping of variables indicated that participants who held stronger mistrust beliefs about the vaccine itself, and who perceived weaker subjective norms for vaccination regarding people close to them, were more likely to say that they would not get vaccinated. Residing in an area of higher (vs. lower) socio-economic vulnerability was marginally associated with not wanting to get vaccinated. For the outcome of positive vaccine intentions ( Table 5 ) , those who trusted the vaccine itself and who held stronger confidence beliefs about the vaccine, and who perceived stronger subjective norms for vaccination, showed higher willingness to get vaccinated. Sensitivity analysis. Because our main analyses categorized "don't know" responses with responses indicative of negative vaccination intentions (i.e., with responses that one would not getting vaccinated, or was not willing to get vaccinated), we conducted a follow-up sensitivity analysis, in which we ran a series of bivariate multinomial logistic regressions modeling vaccination intentions with responses classified separately as positive intentions (would or willing to get vaccinated), negative intentions (would not or not willing to get vaccinated), or "don't know." Relative to positive intentions, significant predictors of "don't know" and negative intentions to get vaccinated were generally the same. However, the magnitude of the associations for the predictors of vaccine beliefs and perceived social norms was greater for positive intentions to get vaccinated than for "don't know" responses (results shown in online Supplemental Appendices A and B). In this nationally representative sample of Black Americans, surveyed about a week after public announcements about vaccine efficacy, we found low intentions to get vaccinated for COVID-19 among about a third of those surveyed (using two different question wordings), similar to previously reported levels at that time. 9 Interestingly, a high proportion of respondents endorsed "don't know" or "not sure" when asked about their intention or willingness to be vaccinated (a quarter of those who were asked if they "would not" get vaccinated, and 38% of those who were asked if they were willing to get vaccinated). Such individuals may have felt that they did not yet have sufficient information about the vaccine to make an informed decision, but they may be more open to change than those who stated that they would not get vaccinated. The present study found that mistrust of the vaccine, concerns about potential harm and side effects, and lack of confidence in vaccine effectiveness and safety are primary factors underlying low vaccine intentions. Previous studies on influenza as well as COVID-19 vaccine hesitancy 23 , 27 , 31 have shown similar results and also have suggested that concerns about safety and efficacy are higher among Black Americans compared to White and Latinx adults. Our analysis further suggests that vaccine-related mistrust is a multifaceted construct that includes distrust of healthcare and healthcare providers (to be equitable), the government (to provide truthful information), and the vaccine itself (to be safe), as well as lack of confidence in vaccine efficacy. Perceived social norms were also important correlates of vaccine intentions, with participants who believed that close others wanted them to get vaccinated being more willing to get vaccinated. Bolstering confidence in our results, these effects were mostly consistent across the two measures of intentions. Additionally, residence in neighborhoods with higher levels of social vulnerability, especially related to socioeconomic status, was associated with unwillingness to get vaccinated. These same types of neighborhoods-those with greater social vulnerability-have been the most affected by COVID-19 and also show lower vaccination rates. 5 , 32 Such neighborhoods may have more residents with lower-wage jobs as essential workers, a higher proportion of individuals living with chronic health conditions, and inadequate healthcare access. Such factors may not only increase COVID-19 risk but also increase medical mistrust if the government response to COVID-19 is perceived to be inequitable. For example, media reports suggest that resources for COVID-19 treatment are less adequate in hospitals in lower-income areas with greater COVID-19 prevalence, compared to hospitals in higherincome areas with lower prevalence. 33 Moreover, the initial disorganized vaccine roll-out in many states combined with some states' lack of first-tier prioritization of nonhealthcare essential workers for vaccination may increase mistrust, if such actions are perceived to be intentional government policies that increase or foster inequities. A key limitation of our analysis is the small sample size, which led to design weights that did not include all key characteristics, such as gender, as well as insufficient statistical power. For example, the effect for social vulnerability was marginally significant in the final model, but significant in bivariate analyses, possibly because of the low sample size to detect geographic differences. In addition, the sample did not include sufficient proportions of especially vulnerable subgroups to examine differences in vaccine intentions, including youth and young adults, sexual and gender minority individuals, and individuals not born in the U.S., who are affected by large health disparities due to intersectionality of identities and inequalities. Moreover, this study only included Black Americans, and thus we could not test whether predictors of vaccine intentions differed by racial/ethnic group. Finally, the present study was conducted prior to the wide-scale availability of vaccination in the U.S., and attitudes about COVID-19 vaccination may have changed since these data were collected. The present study results suggest a need to develop public health messaging prior to launching vaccination roll-out efforts and can inform efforts to increase vaccination for health conditions, beyond COVID-19. In the short term, in addition to transparent and clear messaging detailing safety and potential side effects, acknowledgment of systemic racism and medical mistrust should be explored as a health communication strategy. Moreover, it is essential to determine reasons for lack of vaccination in distinct, meaningful Black subgroups and communities, such as areas of greater socio-economic vulnerability, to tailor messages while working to determine acceptable and trusted vaccine access points among healthcare facilities and community-based organizations. Longer-term, there is a need to establish authentic community collaborations to increase the tr ustwor thiness of the gover nment, the pharmaceutical industry, and health care organizations, so that ongoing positive partnerships are in place to enhance the resilience of communities for future public health challenges, beyond COVID-19. 20 JNMA [mNS REFERENCES 1.
