theres nothing wrong with getting a flu shot. in fact, for most people, its a great idea
most flu shots you will see on the market are not attenuated/whole virii, they are ripped up antigens so theres no chance of backwards infection. if you can afford it and are prone then why not
i wont be getting a shot just now since im not working (in my line of work it really is the front line for any infection) and im currently in the throes of a flu- sore throat, muscle aches, lethargy, lightheadedness, headache
it sucks balls i must say. havnt had anything like this in a while
