Hi everyone.

I’m a teacher and struggling right now to live a normal life based around covid. I have kids in my class off currently with it but because we are double vaxed, can just go about as normal. I’ve been doing lateral flow tests all of which are negative to this point but I’m wondering if I’m missing something. Have I don’t it right. Maybe I didn’t leave it in solution long enough? My main fear is reinfection as I hated having covid last time. Has anyone been reinfected? X
