I'll just make a few independent observations, Richard; a mirror approach is not appropriate since lockdowns and vaccinations are completely orthogonal approaches to suppressing a virus. Either, both or neither can be tried, with varied results. There will be many lockdown zealots who renounce vaccination and vice versa in both directions.
Some data from Israel suggests vaccines are 94% effective at stopping infections. Few here would vouch for Lockdowns, but there are plenty of people elsewhere who do think lockdowns work, although it would be hard to quantify that in the same way vaccines can be quantified.
Support and antagonism for lockdowns and vaccination can also be orthogonal, one is able to support or renounce both independently. My personal view is that vaccination is safe and effective and that lockdowns do more harm than good. My views may be represented in some of my posts ; if you are an anti-vaxxer, you'll just have to suck that up, I'm afraid, but I wish you well whatever. I see vaccination as a way to reach herd immunity, making it politically possible to drop lockdown; I hope we have almost reached that point, as does the government.
I'll finish with one remark. We will soon be getting data on covid deaths of those vaccinated, versus those not vaccinated. Since we are reaching the end of the virus season, there are reasonable grounds to hope that the number of covid deaths of those vaccinated will be a very small cohort indeed compared to the total. If this is the case, it greatly diminishes the SAGE/government case for lockdown, since vaccination, not lockdown will be seen to be the primary effective measure.
