I want to turn to the issue of extending second doses to four months.
Cole Pinnow, the president of Pfizer, said the following this week to this committee:
All the research to date on our vaccine has been done with two doses that have a schedule of 21 days. The recommendation that's been put in place by NACI, as highlighted earlier, in Canada is the only one in the world that is recommending an extended dose delivery.
He then continued:
The data that we've seen from a real-world evidence perspective that has been used to make arguments to extend the dose schedule has been with regard to much younger populations. The fact is that we don't have any data after two months to know what the impact of one dose will be.
Is extending the dose interval to four months a responsible choice for older populations in light of what Mr. Pinnow told this committee?
