Many here seem to think that "taking one for the team" is the unselfish thing to do
but what if there are long term problems for yourself that may effect the quality of your life forevermore ?
I had the flu back in the mid-1980s. It was so bad, that ever since I've gotten a flu shot every year. Very occasionally, I get a slight fever the next day. Haven't had the flu once since then. I get the pneumonia vaccination as well.
I think any potential long-term problems of flu vaccinations are far outweighed by the long-term real problems of having the flu itself. Check the stats of those who catch the flu. Death is a very real possibility, as well as other documented ways flu can damage you.
Getting the flu shot not only helps prevent your getting the flu, it helps prevent spreading flu to your family, friends, and coworkers.
