I was innoculated against 'flu in mid-Nov.. I caught it last week. My Dr. (and local nurses) say that this year the virus has mutated or (they whisper this) the wrong strain was chosen to innoculate against. They have several patients like me who were definitely supposed to be OK. It's the usual sort of thing, but on Mon. I began with Bronchitis as a result and have been really ill until pulling round last night. Still hacking and tiring easily, so confined to barracks and resting every hour or so. Keep hydrated and eat as much as you can (I know it's not much).
My symptoms were yours grandpajoe - until the racking coughing spasms set in. I didn't cough up blood, but could taste it in my throat. Hang on in !
