A Vaccination Strategy for Ontario COVID-19 Hotspots and Essential Workers

Ontario’s initial mass COVID-19 vaccination strategy in place until April 8, 2021 was based on per-capita regional allocation of vaccines with subsequent distribution – in order of relative priority – by age, chronic health conditions and high-risk congregate care settings, COVID-19 hotspots, and essential worker status. Early analysis of Ontario’s COVID-19 vaccine rollout reveals inequities in vaccine coverage across the province, with residents of higher risk neighbourhoods being least likely get vaccinated. Accelerating the vaccination of COVID-19 hotspots and essential workers will prevent considerably more SARS-CoV-2 infections and COVID-19 hospitalizations, ICU admissions and deaths as compared with Ontario’s initial mass vaccination strategy (Figure 1).
