Great Influenza Information
Dr. Steve Novella has a nice post up over at Neurologica that answers a common question about the flu vaccine and vaccines in general. As a health-care worker I get asked about that stuff all the time and you'd be surprised how much the silly anti-vax talking points make their way into the lay-person vocabulary and ideology. It takes some calm talking down, but most of them come around eventually.
Both Dr. Novella and Dr. Mark Crislip have excellent articles on flu vaccine efficacy (and everything else).
