Vaccination status of #Covid19 cases/deaths since #CovidVaccine program began Dec 2020 in Ontario.

#FullyVaccinated people account for a tiny % of cases/deaths!🙏🏻

This may partly be because there weren't many #FullyVaccinated ppl until recently.
Vaccines reduce symptom severity so less testing may also be done.
Graph shows most post-vax cases occurring before efficacy onset (7d+ after dose 2)
