This isn't fair. The bests tests in the world have 95-97% accuracy in regards to false positives/false negatives, and that is if they are run by the book correctly. So, in 1000 tests even the best tests in the world are going to have approx 40 false results. I haven't seen much to make me think these accruate covid tests are much worse than that.. I think some of them are 88% or so, but even that is on par with other acceptable tests in usage in the medical industry, so they aren't "bad" at all. And a vaccine and its efficacy has nothing to do with tests and their accuracy. A vaccine can be considered "good" even with 50% efficacy and usable at 30%. The efficacy of a vaccine has little to do with the vaccine itself, as in, the vaccine will do what it is programmed to do.. The variation in how effective it is has everything to do with the flexibility of the virus you are trying to vaccinate against. In the case of flu and covid, they are slippery little things so it may be hard to come up with a slam dunk vaccine for them, due to the fact that they are nimble, not due to the fact that vaccine makers are inept.
