Because I've just tested positive for the FIFTH time, triple vaccinated! Is there something wrong with my immunity?? I tend to test positive for ages when I get it as well, so there's a chance time 1-2 were actually just one, but that still leaves me with four infections. My sister was really bewildered and said she'd never heard of someone having it so many times and testing positive on lat flow for weeks after. Is there something possibly wrong with me?
