Influenza Sucks!

Seriously-what was the point of the flu shot? I got it about a month ago-only because my dr. made me because of my asthma. She said with the flu being mainly a respiratory situation-its better to get the shot if you've got severe asthma like I do-so I got it....and now look-I'm sick with influenza....nice. Although I haven't gotten the bill yet for my visit that day for my annual and all the blood work-I'm tempted to raise hell for the charge of the shot. If I get it today-the only problem-I don't have a voice-so I can't even call. Grrr....
