Thank you, Mr. Chair.
I'd like to take a moment to acknowledge the one-year anniversary since COVID-19 was declared a pandemic, and the lives across Canada that have changed, some of them forever. Today, my respect goes out to all who have lost loved ones and friends, and to our health care heroes who have been on the front line of this fight since the very beginning, as well as to our scientific community, including the ones who are here with us today. I want to thank you all for joining us.
I'll begin with a question for Dr. Njoo. I believe some Canadians may not be aware of the reason why COVID-19 vaccines use a two-dose schedule to reach the very high levels of immunity. Can you walk us through how each of us will gain immunity to COVID-19 through vaccination? Let's start with getting the first dose and going through to the second.
