Variables
-
The general objective of this study is to assess the COVID-19 risk profile of Montréal North’s residents in relationship to their sociodemographic characteristics as well as their biological immunity to the virus as determined through the presence of antibodies for COVID-19.
The specific objectives are:
* To use results from population surveys and serological tests to improve understanding as to why Montreal North is disproportionately affected by COVID-19 compared to other boroughs of Montreal, and thus ultimately improve assessments of current efforts aimed at mitigating COVID-19 risk in the area through public health measures including vaccination;
* To help identify the reasons for infection and immunity in high-risk areas as compared to lower-risk ones, and their impact on vaccination uptake;
* To foster connections between stakeholders, providing providing constructive knowledge transfer and dissemination.
