If the vaccines are working in a meaningful way then there will be no need for vaccine passports or further lockdowns, or indeed any other measures.
That definition of meaningful (and all, including mine) are matters of debate. There do seem to be very high expectations of what vaccines can and cannot do, and in what timeframe.
Right now we have an R0 of just over one, with a virus with an R of 6-7. We are undoubtedly still below pre-pandemic contact levels but few other NPIs remain in place, it seems difficult to me to argue that vaccines aren’t playing a significant role in stopping rapidly exponential growth in cases, and therefore in hospitalisations and deaths which are still linked, though at a much improved ratio.
I don’t take the same ‘all or nothing’ approach to vaccines as some seem to; I think they have a very useful role to play and are already playing that role.
If they aren't working as expected, which is obviously the case, then we need to be having a conversation about where to go from here.
How do you define ‘as expected’? Before trials, most scientists were saying that they would be impressed with much lower reductions in severe disease and death, and that any reduction in infection wasn’t a given.
Doubling down on a treatment that has limited efficacy is not the way out of this.
Again, we have different views of what limited effectiveness is. (Efficacy generally refers to performance in controlled trial conditions; effectiveness to real-world performance.)
