title: Influenza vaccination.
abstract: I was amazed at some of the things I learned from this article - for example, that the influenza vaccine can reduce mortality by up to 75 per cent and that preventing influenza can halve the chances of a major heart attack. Pneumonia is a major complication in influenza and this can often be fatal. Terms such as 'antigenic drift' and 'antigenic shift' were new to me and I found it beneficial to check the meaning of terms like 'natural', 'acquired', 'active' and 'passive' immunity.
