Factors influencing intent to receive COVID-19 vaccination among Black and White adults in the southeastern United States, October - December 2020

COVID-19 vaccine confidence, concerns, and uptake in children aged 5 and older in Calgary, Alberta: a longitudinal cohort study

Objectives

Beginning early in the pandemic, there was a worldwide effort to develop effective vaccines against the SARS-CoV-2 virus. Before and after the approval and implementation of vaccines, there were concerns about their need as well as their safety and rapid development. We explored child demographic characteristics and parental concerns to identify factors associated with the decision to vaccinate.

Methods

A cohort of 1035 children from Calgary was assembled in 2020 to participate in 5 visits every 6 months for survey completion and blood sampling for SARS-CoV-2 antibodies. Visits 1 to 2 occurred before approval of vaccines for children; Visits 3 to 5 occurred after vaccine approval for different age groups. We described vaccine concerns and utilized logistic regression to examine factors associated with the decision to vaccinate in children ≥5 years of age.

Results

Children ≥12 years of age, of non-white or non-black ethnicity, and who had received previous influenza vaccines had higher odds of being vaccinated against SARS-CoV-2. Children with previous SARS-CoV-2 infection had lower odds of being vaccinated. The most common concerns in early 2021 were about vaccine safety. By summer 2022, the most common concern was a belief that vaccines were not necessary. Through the study 88% of children were vaccinated.

Conclusions

Age, ethnicity, previous infections, and vaccine attitudes were associated with parental decision to vaccinate against SARS-CoV-2. For children who remained unvaccinated, parents continued to have safety concerns and questioned the necessity of the vaccine. Complacency about the need for vaccination may be more challenging to address and overcome than concerns about safety alone.

A Scoping Review on Gender/Sex Differences in COVID-19 Vaccine Intentions and Uptake in the United States

OBJECTIVE

To explore the empirical literature on gender/sex differences in vaccine acceptance among U.S.-based adults and adolescents in approximately the first 2 years of the pandemic.

DATA SOURCE

Embase, Medline, PsycINFO, EBSCO, CINAHL, Web of Science.

STUDY INCLUSION AND EXCLUSION CRITERIA

Peer-reviewed studies conducted in the U.S. with those aged 12 and older, published in English before January 12, 2022, examining the relationship between gender/sex on COVID-19 vaccine intentions and/or uptake.

DATA EXTRACTION

Three authors screened studies and extracted data.

DATA SYNTHESIS

Univariate and multivariate results are summarized.

RESULTS

A total of 53 studies met inclusion criteria (48 intentions, 7 uptake), using mostly cross-sectional designs (92.5%) and non-random sampling (83.0%). The majority of studies supported men's greater intentions to vaccinate compared to women, and men's greater vaccine uptake in univariate analyses, but most multivariate analyses supported no gender differences in uptake. Few studies examined gender beyond binary categories (women/men), highlighting a gap in the studies inclusive of transgender or gender-diverse populations in analyses.

CONCLUSION

Women may have been more hesitant to get the vaccine than men early in the pandemic, but these differences may not translate to actual behavior. Future research should include non-binary/transgender populations, explore the gender-specific reasons for hesitancy and differences by sub-populations, utilize more rigorous designs, and test gender-sensitive public health campaigns to mitigate vaccine concerns.

Trust in science and scientists among university students, staff, and faculty of a large, diverse university in Los Angeles during the COVID-19 pandemic, the Trojan Pandemic Response Initiative

BACKGROUND

Mistrust in science and scientists may adversely influence the rate of COVID-19 vaccination and undermine public health initiatives to reduce virus transmission.

METHODS

Students, staff and faculty responded to an email invitation to complete an electronic survey. Surveys included 21-items from the Trust in Science and Scientists Inventory questionnaire. Responses were coded so higher scores indicated a higher trust in science and scientists, A linear regression model including sex, age group, division, race and ethnicity, political affiliation, and history of COVID-19, was used to determine variables significantly associated with trust in science and scientists scores at the p < 0.05 level.

RESULTS

Participants were mostly female (62.1%), Asian (34.7%) and White (39.5%) and students (70.6%). More than half identified their political affiliation as Democrat (65%). In the final regression model, all races and ethnicities had significantly lower mean trust in science and scientists scores than White participants [Black ([Formula: see text]= -0.42, 95% CI: -0.55, -0.43, p < 0.001); Asian ([Formula: see text]= -0.20, 95% CI: -0.24, -0.17, p < 0.001); Latinx ([Formula: see text]= -0.22, 95% CI: -0.27, -0.18, p < 0.001); Other ([Formula: see text]= -0.19, 95% CI: -0.26, -0.11, p < 0.001)]. Compared to those identifying as Democrat, all other political affiliations had significantly lower mean scores. [Republican ([Formula: see text] =-0.49, 95% CI: -0.55, -0.43, p < 0.0001); Independent ([Formula: see text] =-0.29, 95% CI: -0.33, -0.25, p < 0.0001); something else ([Formula: see text] =-0.19, 95% CI: -0.25, -0.12, p < 0.0001)]. Having had COVID-19 ([Formula: see text]= -0.10, 95% CI: -0.15, -0.06, p < 0.001) had significantly lower scores compared to those who did not have COVID-19.

CONCLUSION

Despite the setting of a major research University, trust in science is highly variable. This study identifies characteristics that could be used to target and curate educational campaigns and university policies to address the COVID19 and future pandemics.

COVID-19 Vaccination: Comparison of Attitudes, Decision-Making Processes, and Communication among Vaccinated and Unvaccinated Black Americans

BACKGROUND

COVID-19 vaccination rates remain suboptimal among Black Americans who disproportionately experience higher hospitalization and death rates than White Americans.

METHODS

We conducted a multi-method (interviews and surveys) study among 30 Black Americans (n = 16 vaccinated, n = 14 unvaccinated) to explore factors related to vaccination hesitancy, decision-making processes, and communication related to uptake. Participants were recruited by using community-driven approaches, including partner collaborations. Thematic analysis was used to analyze qualitative data, and descriptive and bivariate analysis was used for quantitative data.

RESULTS

Of those unvaccinated, 79% (n = 11) stated they were delaying and 21% (n = 3) were declining vaccination indefinitely. When asked about the likelihood of vaccine initiation in 6 months and 12 months, 29% (n = 4) and 36% (n = 5), respectively, stated that they would receive the vaccine. The following themes emerged: (1) COVID-19 vaccination hesitancy exists on a continuum; (2) varied decision-making processes for COVID-19 vaccination; (3) motivators among vaccinated individuals; (4) barriers among unvaccinated individuals; (5) retrieving and navigating vaccine information within the COVID-19 infodemic; and (6) parent perspectives on child vaccination.

CONCLUSIONS

Findings suggest that vaccinated and unvaccinated participants had similar and dissimilar perspectives in decision-making processes and vaccine concerns as shown in the Decision-making Processes for the COVID-19 vaccination (DePC) model. Based on these findings, future studies should further explore how factors influencing decision-making can lead to divergent outcomes for COVID-19 vaccination.

Prevalence and Assessment of Factors Associated with COVID-19 Vaccine Hesitancy in an Ethnic Minority Oncology Patient Population

BACKGROUND

Complicating the COVID-19 pandemic are the healthcare disparities experienced by ethnic minorities, especially those with comorbidities including cancer. The introduction of COVID-19 vaccines has been instrumental in blunting the morbidity and mortality from the pandemic; however, vaccine hesitancy, particularly among ethnic minorities, has been a major concern. Thus, we sought to evaluate the knowledge and perspectives of COVID-19 and vaccines among our ethnic minority cancer patient population.

METHODS

Following an IRB approved protocol, questionnaires were completed by patients in a predominantly ethnic minority population at a single institution between 1 February and 30 June 2021. Included were any adult cancer patients with either a solid or hematologic malignancy.

RESULTS

Among the 84 patients that were offered the questionnaires, 52 patients responded, with a median age of 63.5 years. Overall, 36% were non-Hispanic Blacks and 30% were Hispanics; 65% were receiving active treatment for their cancer. Seventy-nine percent believed COVID-19 to be dangerous or harmful to them, 61% were concerned about the side effects, yet 65% considered COVID-19 vaccines as safe. Among the seven patients that refused the vaccine, (71%, n = 5) cited side effects and/or (57%, n = 4) believed that the vaccine was not needed. Overall, there was a significantly higher chance of being vaccinated if patients were receiving active cancer treatment, believed COVID-19 was harmful, or that the vaccine was safe, and knew COVID-19 was a virus.

CONCLUSIONS

This exploratory study demonstrates that most ethnic minority cancer patients are receptive to vaccines, with a majority being vaccinated. However, we also discovered various reasons why this group of patients may not want be vaccinated, including concerns about side effects and perception that COVID-19 is not harmful. These findings can help us further understand the complex nature of vaccine hesitancy in ethnic minority cancer patients, and aid in developing future vaccine awareness strategies as the COVID-19 pandemic continues to evolve.

Development of a Theory-Based, Culturally Appropriate Message Library for Use in Interventions to Promote COVID-19 Vaccination Among African Americans: Formative Research

Background

Disparities in COVID-19 incidence, hospitalization, and mortality rates among African Americans suggest the need for targeted interventions. Use of targeted, theory-driven messages in behavioral and communication interventions could empower African Americans to engage in behaviors that prevent COVID-19.

Objective

To address this need, we performed a formative study that aimed to develop and design a culturally appropriate, theory-based library of messages targeting concerns around COVID-19 vaccines that could be used in behavioral and communication interventions for African Americans.

Methods

Message development occurred between January 2021 and February 2022. Initial messages were designed by a multidisciplinary team of researchers, community leaders, and community members. Kreuter’s 5 strategies (ie, linguistic, peripheral, evidential, sociocultural, and constituent-involving strategies) were used to achieve cultural appropriateness. After forming a community-academic partnership, message development occurred in 4 phases: (1) adaptation of a message library using the literature, (2) review by 6 clinical and research experts for content validation, (3) input and review by a 6-member community advisory panel (CAP), and (4) message pretesting with African Americans via semistructured interviews in a qualitative study.

Results

Themes from the semistructured interviews among 30 African Americans were as follows: (1) community reactions to the messages, (2) community questions and information needs, (3) suggestions for additional content, and (4) suggestions to improve comprehension, relevance, and trustworthiness. Feedback from the CAP, community members, and scientific experts was used by members of the community-academic partnership to iteratively update message content to maximize cultural appropriateness. The final message library had 18 message subsets for adults and 17 message subsets for parents and caregivers of children. These subsets were placed into 3 categories: (1) vaccine development, (2) vaccine safety, and (3) vaccine effectiveness.

Conclusions

We used a 4-phase, systematic process using multiple community engagement approaches to create messages for African Americans to support interventions to improve COVID-19 vaccination rates among adults and children. The newly developed messages were deemed to be culturally appropriate according to experts and members of the African American community. Future research should evaluate the impact of these messages on COVID-19 vaccination rates among African Americans.

Characteristics and Procedures Among Adults Discharged to Hospice After Gastrointestinal Tract Surgery in California

IMPORTANCE

Hospice care is associated with improved quality of life and goal-concordant care. Limited data suggest that provision of hospice services after surgery is suboptimal; however, literature in this domain is in its nascency, leaving gaps in our understanding of patients who enroll in hospice after surgery.

OBJECTIVE

To characterize the transition to hospice after gastrointestinal tract surgery and identify areas that warrant further attention and intervention.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cohort study included patients discharged to hospice after a surgical hospitalization for a digestive disorder in California-licensed hospitals between January 1, 2015, and December 31, 2019. Data were analyzed from August 1 to November 30, 2021.

EXPOSURES

Patient age, race and ethnicity, principal language, payer, and Distressed Community Index (DCI).

MAIN OUTCOMES AND MEASURES

Admission type and most common diagnoses and procedures for surgical hospitalizations that resulted in discharge to hospice, annual hospitalization trend for 3 years preceding hospice enrollment, and most common diagnoses for patients who were readmitted after hospice enrollment were summarized. Age, race and ethnicity, principal language, payer, and DCI were compared between patients who were readmitted after hospice enrollment and those who were not.

RESULTS

Of 2688 patients with surgical hospitalizations resulting in discharge to hospice (mean [SD] age, 73.2 [14.7] years; 1459 women [54.3%]), 2389 (88.9%) had urgent or emergent discharges. The most common diagnoses were cancer (primary and metastatic; 1541 [57.3%]) and bowel obstruction (563 [20.9%]). The most common procedures were bowel resection, fecal diversion, inferior vena cava filter, gastric bypass, and paracentesis. In the 3 years preceding hospice enrollment, this cohort had a mean (SD) of 2.21 (2.77) hospitalizations per patient (1537 of 5953 surgical [25.8%]). Of these, 3594 of 5953 total (60.4%) and 840 of 1537 surgical (54.7%) hospitalizations were within 1 year of hospice enrollment. Three hundred and sixty-eight patients (13.7%) were readmitted after hospice enrollment, with infection being the most common readmission diagnosis. Readmitted patients were more likely to be younger (mean [SD] age, 69.7 [16.4] vs 73.8 [14.3] years; P < .001), to speak a principal language other than English (62 of 368 [16.8%] vs 292 of 2320 [12.6%]; P = .02), to be insured through Medicaid (70 of 368 [19.0%] vs 223 of 2320 [9.6%]; P < .001), and to be from a community with higher DCI (198 of 360 [55.0%] vs 1117 of 2269 [49.2%]; P = .04) and were less likely to be White (195 of 368 [53.0%] vs 1479 of 2320 [63.8%]; P < .001).

CONCLUSIONS AND RELEVANCE

These findings suggest multiple opportunities for advance care planning in this surgical cohort, with a particular focus on emergent care. Further study is needed to understand the reasons for rehospitalization after hospice discharge and identify ways to improve communication and decision-making support for patients who choose to enroll in hospice care. Given the frequent antecedent interactions with the health care system among this population, longitudinal and tailored approaches may be beneficial to promote equitable end-of-life care; however, further research is needed to clarify barriers and understand differing patient needs.
