It’s “trendy” to have a pop at Blair isn’t it?
You are not going to win an argument on this forum, or in a lot of other places, blindly defending Blair and his views. Therefore I suggest you use your energy elsewhere for more productive matters, such as trying to find out why exactly people haven't taken the vaccine, and it won't all be for one reason.
Examples include those under 12 haven't taken it because they're not eligible; being concerned about safety of the vaccines; wondering what the point is if restrictions are not going away; and of course, conspiracy theories on the internet. To these I propose the following solutions: make it eligible for under 12s if the evidence supports them taking it, present comprehensive evidence of safety to those not yet convinced, stop using NPIs like we are, as if vaccines don't do anything, and in general work on more hospital capacity and staff numbers and pay. For conspiracy theories better media regulation is needed.
I would also add Portugal has vaccinated 89% of its population, but they are still bringing in restrictions now in response to rising cases, as if those vaccines do nothing. In my opinion this is what will undermine vaccines most, and makes any Government behaving in such a way the biggest anti-vaxxers going. We are not going to get 100% support for vaccines, because nothing in life ever gets 100% support; if society can collapse because of as little as 11% doing/not doing a certain act, we either have too high expectations, or society doesn't have sensible resilience in place.
