My four-year-old grandson, who has leukemia, was just diagnosed with the flu despite having the shot this year. I also had the shot prior to my diagnosis. Obviously it doesn't cover strain B, which is what he has. My husband and I kept him until this morning so we have been exposed big time. Does anyone know about Tamiflu and whether or not it should be taken with HCV. My guess is it's okay, but my hepa will not respond to any of my questions, so I'm asking here.
