"Not one of the 1359 previously infected subjects who remained unvaccinated had a SARS-CoV-2 infection over the duration of the study."
The duration of the study being 5 months.
There's no indication from this study what would happen after 5 months.

> This study was not specifically designed to determine the duration of protection afforded by natural infection, but for the previously infected subjects the median duration since prior infection was 143 days (IQR 76 – 179 days), and no one had SARS-CoV-2 infection over the following five months, suggesting that SARS-CoV-2 infection may provide protection against reinfection for 10 months or longer.
As such, most infected participants would have been recently infected in a situation with low and decreasing virus circulation. Nobody thinks there's any risk of reinfection at that point.
