The jabs recommence
At this point I think that people are so eager to get any vaccine that they'll happily take this one.
I guess the question is whether you can get to herd immunity with this or if it will stall out at under 70% take up (including children, who can't get it).
Ultimately, I don't think it will matter because production of other vaccines will fill in the gaps. A bigger worry is that the AZ jab doesn't cover all the variants.
