ARR is completely irrelevant metric for individuals and does not tell anything about actual risk reduction because it is always relative. I want to know by how much is my risk greater when I am not vaccinating.<p>ARR is only relevant for specific study/time that in most cases is unknown property - you will have no idea what would be the epidemiological situation after 3 months for example.
This is cherry-picking numbers to make vaccines look ineffective. It focuses on attack rate, rather than the risk of hospitalization and death, and it ignores the importance of lowering the attack rate in slowing the overall spread of the virus.
All true and accurate, and pertinent so long as you care 100% about whether you're infected or not, and 0% about whether your infection is of the kind that requires an ICU bed or not.<p>Feh.
