I don'tvknow Tegan just that a cousin's wife has a nasty lung condition which means she gets chest infections on a rolling basis and the treatment is always the same: an anti -b which does not clear it, a recurrence which lands her in hospital 2 weeks later, then heavy duty anti-b's usually IV which work but of course a week in hospital has cost the NHS more, her dog has had to go into kennels and something which could have been cleared up in the first week has taken over 3. DD had pneumonia last autumn and likewise, the first course of meds had no impact. It is worrying. I was told I am eligible for my pneumonia jab, but oops they've run out and to try after Christmas!!
