I'd be pleased to share the good news from Pfizer today. We have negotiated the exercise of an additional eight million options with Pfizer, so that means that not only are we purchasing these options, but they're going to be delivered in the very short term.
We expect to have two million doses of Pfizer delivered in May, and 12 million over five weeks in June. In addition to the other vaccines in our portfolio, this means we are going to, cumulatively, have between 48 million and 50 million vaccines in this country prior to the end of June.
I want to reiterate that when we put our contracts into place last summer—and indeed our portfolio is a diversified one, with multiple contracts and multiple suppliers—we wanted to make sure we had access to multiple sources of vaccine supply. We are pulling vaccine now not only from Pfizer but also from Moderna, AstraZeneca and J&J. That is very important.
I would like to clarify a point about our rankings. I was speaking about the G20, whereas my honourable colleague was speaking about all countries in the world. We are indeed second in the G20 for the rate of vaccinations, and fourth in the G20 for the total doses administered per 100 people. Why? It's because of our diversified portfolio, and because we're pulling in vaccine from multiple sources.
We will continue to do that, and distribute those vaccines to the provinces and territories as soon as we receive them. Indeed, Pfizer's go directly to the provinces and territories as it currently stands. We want to make sure we are with Canadians and supporting Canadians right through to the end of this pandemic with our vaccines.
