Disparate Impact of the COVID-19 Pandemic and Health Equity Data Gaps

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.

Strategies to address COVID-19 vaccine hesitancy in First Nations peoples: a systematic review

BACKGROUND

First Nations peoples face disproportionate vaccine-preventable risks due to social, economic, and healthcare disparities. Additionally, during the COVID-19 pandemic, there was also mistrust and hesitancy about the COVID-19 vaccines among First Nations peoples. These are rooted in factors such as colonial histories, discriminatory medical practices, and unreliable information.

OBJECTIVE

To examine strategies to address COVID-19 vaccine hesitancy among First Nations peoples globally.

METHODS

A systematic review was conducted. Searches were undertaken in OVID MEDLINE, OVID EMBASE, OVID PsycINFO, CINAHL, and Informit. Searches were date limited from 2020. Items included in this review provided primary data that discussed strategies used to address COVID-19 vaccine hesitancy in First Nations peoples.

RESULTS

We identified several key strategies across four countries - Australia, the USA, Canada, and Guatemala in seventeen papers. These included understanding communities' needs, collaborating with communities, tailored messaging, addressing underlying systemic traumas and social health gaps, and early logistics planning.

CONCLUSION

The inclusion of First Nations-centred strategies to reduce COVID-19 vaccine hesitancy is essential to delivering an equitable pandemic response. Implementation of these strategies in the continued effort to vaccinate against COVID-19 and in future pandemics is integral to ensure that First Nations peoples are not disproportionately affected by disease.

Implications of Undocumented Status for Latinx Families During the COVID-19 Pandemic: A Call to Action

BACKGROUND

A disproportionate number of COVID-19 cases and deaths have been reported among Latinxs in the U.S. Among those most affected by the pandemic are marginalized families, including those that are undocumented and mixed-status, in which some, but not all members are undocumented. Undocumented and mixed-status families face multiple and chronic daily stressors that compromised their health and wellbeing. Salient stressors faced by undocumented Latinx families include poverty, social disadvantage, discrimination, dangerous living and working conditions, and limited access to healthcare. These stressors are frequently compounded with trauma, fear of detention, deportation, and family separation.

PURPOSE

Informed by the literature and insights from our community-based work to address the health needs of undocumented and mixed status Latinx families during the pandemic, this paper uses a social determinants of health lens to present a narrative summary that highlights four primary psychosocial stressors faced by these families and their implications for mental health.

DISCUSSION

These include stressors pertaining to (a) anti-immigrant rhetoric and actions; (b) family stressors and disruptions in family dynamics; (c) economic changes and financial losses; and (c) limited access to healthcare. Implications of the aforesaid stressors on the mental health of undocumented families and youth are also discussed. In addition, recommendations are provided for the provision of mental health services, best practices, and resources from a strengths-based approach.

Wastewater surveillance facilitates climate change-resilient pathogen monitoring

Traditional disease surveillance systems are ill-equipped to handle climate change-driven shifts in pathogen dynamics. If paired with wastewater surveillance, a cost-effective and scalable approach for generating high-resolution health data, such next-generation systems can enable effective resource allocation and delivery of targeted interventions.

Delivering COVID self-tests through GetaKit.ca: Creating testing access during a pandemic

OBJECTIVES

To determine the real-world outcomes associated with using the GetaKit.ca website to distribute COVID self-tests to persons with risk factors, with a focus on facilitating testing for persons who are Black, Indigenous, or of Colour (BIPOC).

METHODS

GetaKit was an open cohort observational study to distribute free self-tests, starting with HIV self-testings and then adding the Lucira Check-It® COVID self-test. Participants would register on our website and complete a risk assessment, which would calculate their need for each type of testing.

RESULTS

Focusing on the COVID self-tests, from September to December 2021 (with targeted outreach in winter 2022), we distributed 6474 COVID self-tests to 3653 persons through 4161 unique orders, of which 47% came from BIPOC participants. Compared to white participants, BIPOC participants were more likely to have been a contact of COVID but less likely to be vaccinated. As well, 69% of results were reported back via the GetaKit.ca website, with 5.3% of these being positive. The positivity rate for our 3653 participants was 9.6%.

CONCLUSIONS

Delivering COVID self-tests via our website provided tests to BIPOC communities and yielded positivity rates that matched local COVID testing centres. This highlights the utility of such systems for delivering testing during future pandemics.
