>There are multiple documented cases where a person caught COVID twice
There have been far more breakthrough cases of fully vaccinated people than there have been confirmed reinfections.

Yeah, but there are vastly more vaccinated people than people have been confirmed infected even once, so that doesn’t really tell you anything. (Currently, the number of vaccination doses being delivered per day globally is about 1/5 the total number of confirmed global COVID cases.)
We'd need to compare the number of confirmed reinfections divided by confirmed infections with the number of breakthrough cases divided by the number of fully vaccinated people.
Its also worth noting the confirmed reinfection count is on a much longer time scale than breakthrough infections. So we currently have more data about the long term natural immunity than we do for vaccinated immunity.
