My point is that while these things might be true to a degree,we need to stress that breakthrough infections are common and sometimes they result in death or severe COVID. Definitely not a reason to mandate vaccines to stop transmission. Maybe a 25% reduction in deaths is good

Pre covid, NO ONE ever talked about 'break through infections' for a 'vaccine'. It either worked or not. Polio less than 500 cases WORLDWIDE last year, because that vaccine works; covid, not so well, but we call it a 'vaccine' and pretend it works like one so people feel better.

Sure, because no one killed anyone when the flu vaccine didn't really work, so it wasn't a big deal. (Some efficacy with the flu vaccine, but if it you still got/ spread the flu, who cares only 34K annual flu deaths.)

afaict this is still quite an effective vaccine, but the virus is evolving, what you gonna do?

The reported 95% efficiency is Relative Risk Reduction. Absolute Risk Reduction is less than a percent. (page 3 table 1, upper left n values of 162 and 8 in a set of about 18K people) https://www.thelancet.com/cms/10.1016/S2666-5247(21)00069-0/attachment/bb4bb1cf-8d64-453f-a2b7-e1b95194c109/mmc1.pdf …

Think of it this way; which number sells more covid shots and makes people feel better; RRR at 95% or ARR at 0.84%? The average person can hardly read a newspaper let alone be discerning enough to care about RRR vs ARR.

but don’t you know what absolute risk reduction is? it’s always lower unless the whole population is exposed during the current period of the study

True but consider two scenarios with Two groups of 10K people. Scenario one: 162 cases in group with no shots and 8 cases with shots so 154 cases reduction. RRR is 95% (154 / 162). ARR is 1.54% ( 154 / 10,000), which does not sound as good as the RRR of 95%.

yeah it’s definitely worse marketing but it’s also objectively a less useful measure than the relative protection, unless you’re really just trying to highlight that this is a rare disease, which during this delta wave it most certainly is not

No. It's to say that the vaccines are 95% effective, which clearly they aren't.
