Pfizer vaccine's protection against Covid wanes quickly in kids 5-11, study says

I wonder if there is a noticeable hospitalization benefit for healthy kids, or if the entire benefit is for kids with serious pre-existing conditions. I tried to find the underlying data, but it doesn't look like it's published.
The study in question states that effectiveness against hospitalization also wanes (unless I misinterpreted "declined changed"):
> "During the January 24-30 week, [...] [vaccine effectiveness] against hospitalization declined changed [...] from 100% (95% CI: -189%, 100%) to 48% (95% CI: -12%, 75%) for those 5-11 years"
