Reinfection and immune suppression on prednisone

Hi, I couldn't find a thread on this but wasn't exhaustive. I have been recently diagnosed with long covid and waiting to see an infectious disease specialist. I tested positive February 8 but am now negative. This was my second covid infection, the first started in late July 2022 and it took a month to recover that time because of inflammation in my lungs (which responded to a steroid inhaler). This time I took Paxlovid and most of my symptoms resolved. However, I continue to experience substantial fatigue and recurring low grade fevers. I started prednisone last week and am on day 6. It didn't help as much as I hoped but I was planning to try working 2 days this week. I work mornings at a preschool. Today, 3 students and 1 teacher tested positive for covid. I know I might have some immunity to covid but I also read the prescription warnings for prednisone to stay away from people with infections. My school is mask optional and I will mask. I'm feeling like it might be too risky to go back to work this week. Does anyone have experience with reinfection and suppressed immunity on prednisone? Thank you!
