Interesting but it's still very early on for any kind of analysis on these numbers, especially with the large number of people who've received only one shot.
I suggest keeping an eye on countries like Israel to see what can be expected in the future, they used Pfizer instead of '<Deleted>' alongside AstraZeneca but it should lay out some kind of roadmap for the future.
The numbers coming out of Israel are not what they hoped for and third shots are being issued right now in what I suspect will be a futile attempt to avoid fresh lockdowns as the hospitals again begin to get pretty busy.
