I went and got my H1N1 vaccine and my seasonal flu vaccine on Thursday. I have type 1 diabetes, so I was in the high risk category and therefore eligible to get it early. The H1N1 shot HURTS way more than the seasonal flu shot. I still have a bump on my arm and it hurts to lift it over my head Other than that, I have had no side effects whatsoever. I think it's worth getting the vaccine.
