A CITF-funded study, published in Water, reported the development and optimization of a method for SARS-CoV-2 detection in wastewater using moderate-speed centrifuged solids. This method was then compared to an ultrafiltration reference method for detection rate, cost, simplicity, and turnaround times.
A CITF-funded study, published in the Journal of Racial and Ethnic Health Disparities, reported on the results of serologic testing for SARS-CoV-2 infections in the Black Canadian community and found that early in the pandemic, Black Canadians had disproportionately higher rates of COVID-19 compared to white Canadians.
A CITF-funded study, published in BMC Infectious Diseases, found that longitudinal sero-monitoring for antibodies, combined with PCR or RAT saliva testing for acute infection, increased the detection of re-infections four-fold compared to PCR or RAT tests alone.
Community-centered research requires trust, cultural appropriateness, and in-depth engagement with participants
A CITF-supported study, published in Health Promotion Practice, presents field notes to provide insights into culturally responsive, trust-centered, and communication-focused strategies that could be used to improve research conducted during a respiratory pathogen pandemic.
At least 47% of people experiencing homelessness in Toronto had a history of SARS-CoV-2 infection by early 2022
In this study update presented as an infographic to the CITF, the research team reported the prevalence of SARS-CoV-2 infection at baseline, incidence of first SARS-CoV-2 infections by six months of follow-up, and the rate of vaccination among people experiencing homelessness in Toronto.
A CITF-supported study, published in medRxiv and undergoing peer review at eLife Sciences, highlighted that to maintain population-level hybrid immunity up-to-date vaccination coverage is required, including among those recovering from SARS-CoV-2 infection.
Among non-vaccinated individuals, South Asians in Canada have an increased risk of SARS-CoV-2 infection, hospitalization, and death compared to non-South Asians
A CITF-funded study, published as a preprint and not yet peer-reviewed, aimed to evaluate the effectiveness of COVID-19 vaccines among South Asians in Ontario compared to non-South Asians. The researchers also assessed the odds of symptomatic COVID-19 infection and related hospitalizations and deaths among non-vaccinated South Asians and non-South Asians.
A CITF-funded study, published in JAMA Network Open, found that people experiencing homelessness had high rates of SARS-CoV-2 infection throughout 2021 and 2022, particularly after the Omicron variant became dominant.
Maternal mRNA COVID-19 vaccination during pregnancy may be protective against adverse newborn outcomes
A CITF-funded study, published in JAMA Pediatrics, reported that maternal mRNA COVID-19 vaccination during pregnancy was associated with lower risks of severe neonatal morbidity, neonatal death, and neonatal intensive care unit (NICU) admission.
Using social media as a source of COVID-19 vaccine information associated with lower rates of vaccine uptake in people who use drugs
A CITF-funded study, published in Scientific Reports, found that only 48% of people who use drugs (PWUD) had received at least two SARS-CoV-2 vaccine doses at baseline in September 2021, much lower than in the general population (70%) in British Columbia at that time.
