Toward enhancing COVID-19 vaccine confidence among African Canadians: Sustainability of immune responses and safety profiles

Upton Allen, Hospital for Sick Children (SickKids) Research Institute

Data on COVID-19 suggests that Black Canadians are disproportionately affected by COVID-19 with higher percentages of cases and severe outcomes than the population at large. This study is looking at the immune responses to COVID-19 vaccines among this group and how long that immunity lasts.

Investigating vaccine access, immunogenicity, effectiveness, and safety among South Asians in Ontario and British Columbia

Sonia Anand and Scott Lear, McMaster University

Canadian South Asian communities are the fastest growing ethnic group in the country. They are also among the highest at-risk populations in Canada for COVID-19. Our study involves an interdisciplinary team of experts and includes 3,000 participants from South Asian communities in the Greater Toronto Area (GTA) and the Greater Vancouver Area (GVA).

COVID-19 vaccination in pregnancy: A province-wide epidemiological assessment of safety and effectiveness using the Better Outcomes Registry & Network (BORN) Ontario Registry

Deshayne Fell, Children’s Hospital of Eastern Ontario Research Institute

This study seeks to assess the safety and effectiveness of COVID-19 vaccination for pregnant individuals by evaluating mother and baby health outcomes. Researchers are using an existing province-wide maternal-newborn registry in Ontario called the Better Outcomes Registry & Network (BORN) and are combining the information collected with data from the Ontario Ministry of Health vaccination registry.

COVID-19 risk and immunity in Montreal North: A population-based study

Jack Jedwab and Simona Bignami, Association for Canadian Studies

Since the beginning of the pandemic, Montreal North has had one of the highest per capita rates of SARS-CoV-2 infection in the city and a lower-than-average vaccination rate. The researchers aim to determine the factors that have put residents at heightened risk of contracting SARS-CoV-2, the extent to which they have been infected, and evaluate vaccine uptake.

Canadian COVID-19 Vaccine Registry for Pregnant and Lactating Individuals (COVERED): An evaluation of safety, effectiveness, and acceptability

Deborah Money, University of British Columbia

Pregnant individuals are at higher risk for COVID-19 complications. Recent real-world evidence shows mRNA vaccines seem safe during pregnancy. Little data is available though, so researchers are studying the safety and effectiveness of vaccines in pregnant and breastfeeding individuals and creating a COVID-19 vaccine registry to better inform future guidance on vaccine usage in this group.

Evaluating the safety and immunogenicity of SARS-CoV-2 vaccines among underserved urban populations with intersecting risk factors for COVID-19 morbidity and mortality: a pooled analysis of three prospective cohort studies in Vancouver, Canada

Hudson Reddon and Brittany Barker, University of British Columbia

Urban centres are home to people from vulnerable populations (those suffering from homelessness, living in group settings, high-intensity substance use and having other infectious diseases such as HIV) who have increased risk factors for catching SARS-CoV-2 and developing serious cases of COVID-19. In this study, researchers are evaluating the uptake, safety and effectiveness of COVID-19 vaccines in these groups.

Seroprevalence of SARS-CoV-2 among African Canadians: Clinical and Epidemiological Correlates

Upton Allen, Hospital for Sick Children (SickKids) Research Institute

In this study, researchers will follow people of African ancestry in Ontario to determine how many have had COVID-19 and to establish the risk factors associated with getting the infection as well as having poor outcomes, including hospitalization and death.

COVID-19 antibodies among high-risk populations in Canada

Philip Awadalla, Canadian Partnership for Tomorrow’s Health (CanPath)

Building on Canadian Partnership for Tomorrow’s Health (CanPath), a national population health research platform that follows the health of 330,000 Canadians, this pan-Canadian study tests 20,000 participants from high-risk populations for antibodies to SARS-CoV-2 (the virus that causes COVID-19), an indication of past infection.

SARS-CoV-2 antibody prevalence in federal and provincial correctional services in Canada

Jim Worthington, Corrections Canada

This study has two aims: to determine the prevalence of SARS-CoV-2 antibodies among people incarcerated at Correctional Service Canada (CSC) institutions, as well as staff; and to describe how incarcerated individuals’ antibodies change over time and how this might differ between subgroups (e.g. race, gender, chronic disease status, vaccine status).

Vaccine Access, Uptake, Effectiveness and Safety in First Nations Communities

Sonia Savitri Anand, McMaster University

Researchers are partnering with three First Nations communities—Six Nations of Grand River, Ontario; Lac La Ronge Indian Band, Saskatchewan; and Wendake, Quebec—to collect, analyze, and report new data related to COVID-19 vaccine effectiveness and safety in these communities. They will also evaluate access to, level of trust, and acceptance of COVID-19 vaccines, among other goals.

What impacts COVID-19 vaccine uptake in Métis Citizens in Ontario? A population-based data linkage study

Martin Cooke University of Waterloo

As COVID-19 vaccines have rolled out across Canada, there has been a high level of vaccine hesitancy in minority populations including Métis. This study will identify factors that impact COVID-19 vaccine uptake in Ontario Métis to, along with consultations with Métis Nation of Ontario citizens and leadership, inform efforts needed to ensure optimal uptake of COVID-19 vaccines in the Métis.
