Simpler explanation on the Israel data: > You’ve probably seen reports from Israel on low vaccine effectiveness in this wave. Is it because of Delta? Waning immunity? We think the reason is mostly that we got the denominator wrong. twitter.com/dvir_a/status/1420059124700… > This is what we got wrong. This “wave” started from cities with high vaccination rate and couldn’t “find” unvaccined adults at risk. The denominator we need to use until mid-July is >95% vaccination rate and not the country’s average. twitter.com/dvir_a/status/1420059139435…

Very good, and I'll add the "denominator problem." Whenever you take an average, you divide by some count. What you choose to count matters, and people can disagree about what belongs in this set. It's often a judgement call. For example, just recently there was a study of vaccine effectiveness in Israel and it appears they made a mistake about the denominator. (Or did they?)
