He has been sick for a couple weeks, with a high fever that keeps coming back. As my colleague described his 8 yr old's last couple weeks. They lined up exactly one day apart. A week of high fever and deep cough, then better, then high fever is back every couple days. My colleague's 8yr old is jabbed and boosted. My younger, and one older kids, all had the same thing first week. Only the 6 year old has recurring high fever, well he and my friends gmo 8yr old. Is there any way to know if he got jabbed? Asking for advice pedes. I'm very concerned right now.
