Yet you omit this part of that report:
Those who chose to receive the bivalent vaccine might have been more worried about infection and might have been more likely to get tested when they had symptoms, thereby disproportionately detecting more incident infections among those who received the bivalent vaccine.
So basically (in the US where the vaccine was highly politicised) if you didn’t believe in the vaccine you probably weren’t in a rush to get yourself tested when symptoms occurred, so the infection appeared lowered amongst unvaccinated.
