El gato malo has now dissected the new Icelandic reinfection study I reported on two days back. As he says, the study shows those with two or more injections to be 42% more likely to get reinfected than those with one or no vaccine dose. This is not a slight, but a considerable difference.
In my original post on the study I quoted the authors’ conclusion that “2 or more doses of vaccine were associated with a slightly higher probability of reinfection compared with 1 dose or less.” But taking this at face value was clearly a mistake. This is not a slightly higher probability, it is considerably higher. Why they state otherwise is a mystery to me. Were they afraid of not getting published otherwise? What other reason might they have to misinterpret their own results so glaringly?
Apart from this, the bad cat points out several flaws in the study. It will be interesting to see if and how the authors respond.
