The only year I had a flu shot I ended up with the worst flu I've ever had, not in reaction to the shot, but later that season. So annoying. I worked in the health sector at the time though (seeing lots of people with colds and flu), so I did tend to catch everything.

Have a good one everyone. It's after 4am and I have to get up early. I'm off to attempt sleep. I haven't been doing very well with it lately.
