I heard about that and I think it's a load of crap. Granted I have nothing to back up my opinion, but I'm not on the flu shot bandwagon. I only got the shot one year because my mother made me and that year was no different than any other year. The flu shot only protects you against some flu viruses and it comes with plenty of side effects. Until I see some concrete proof that I should get the flu shot I will not get it. Most new vaccines are sketchy in my book.
