But it's a bigger majority of people than were given the shorter dosage spacing?
The issue is surely the amount of people tested in total? But regardless, the evidence that is there shows 3 weeks is more eficiant.
I cba arguing the toss. If they're giving people Pfizer, then by all means I don't think they should be extending the doseage. Whatever you think of the AZ one, they've tested the doseage spacing out, and got positive results.
It's better for more people to have more protection. That will do more for surpressing the virus.
