Flu shot

Yesterday I had a flu shot. I had one last year and I think it helped. Of course I'm not too sure but as they give them out for free and they are supposed to do you good then I thought It would be beneficial to me if I got one. This year the vaccine contained both the current seasonal influenza virus but also the H1N1 (Swine Flu) Influenza A virus. I was told that I might experience some side effects such as a fever, sore arm or aches but as yet I haven't felt anything. I'm not sure if it will work but I figure I might as well try to protect myself and do my bit for those around me as I wouldn't want to give anyone the flu as well as wouldn't want to get it from anyone.
