Thanks for mentioning that. Indeed, the Public Health Agency of Canada report that was published in The Globe and Mail this morning is interesting. It notes that 53 infections caused death after receipt of only the first dose, so definitely it's not an impossible occurrence. We have seen at all major institutions patients and health care workers becoming sick after having received only one dose of vaccination.
I can tell you one example specific to the Ottawa Heart Institute. We had an outbreak of COVID-19 about three weeks ago. Very unfortunately, we had more health care workers who were at home with COVID positivity than we had patients themselves who were COVID-positive.
It seems, then, to really be affecting our health care workers primarily, because of the amount of traffic and care provided by health care workers; hence the need for a second dose.
