Please tell me if my understanding is incorrect, I assert ....

That 160+ days seems to come entirely from the study window itself and I don't see how it would give an indication of general immunity of the study cohorts. If you wait longer as more people wind up infected that number only goes up.

To provide some additional context from the linked study, only 5.7 per 100,000 people were reinfected during the study window while 57.3 per 100,000 were infected for the first time. To put it into vaccine effectiveness terms that is a 90% effective. I didn't read to see if the cohorts were demographic matched.

If I'm understanding it correctly, then I think you misrepresent that 160 number.
