ATieLikeRichardGere Thanks for the link although I have to confess t not understanding a lot of it.
Seems the main point as far as efficacy is concerned is the suggestion that the PCR tests that gave a negative result could not be relied on. The data extrapolated from that then produces a figure based on all those negative results actually being positive which seems just as unlikely a scenario.
Whatever the case, as Israel is vaccinating its citizens at a fast pace we should very soon see whether their infection/death rates begin to subside.
