Why the epidemiology of swine flu matters -- (Effect Measure).
The most rational thing to do at this moment, given what we know and don't know, is to get vaccinated with both seasonal flu and swine flu vaccines. That's what I'm going to do. I already got my seasonal flu shot and I'll wait in line for my turn for the swine flu vaccine and get it as soon as I can. You not only protect yourself but you help prevent spread of flu to others.
