Yes there are less effective against delta but 39% seems a outler compared to others
which is what I said in that and subsequent posts. I even posted in my subsequent comment a link to an article that goes into some detail about the Israeli numbers and casts doubt on the low number in that study. And also a link about the uk in relation to a third Pfizer dose which also contains uk efficiency numbers. I suggest you read those. It seems like more work needs doing on the Israeli number as it was a very small sample. And as someone else pointed out, it depends what effectiveness you are measuring against. Any infection no matter how mild or against serious infection requiring hospitalisation or causing death. The vaccines do seem very effective against the latter two, but there does appear to be potentially a drop off in effectiveness, potentially greater than might have been expected.
