Possible: Flu shots are terrific, but they do not cover 100% of the flu strains. Also, when did you get the shot? It takes about two weeks for your body to build up full immunity to the strains it does cover. You could also have a really bad cold or a number of other viral or occasionally bacterial infections that should be self limited. If you do not start to get better after a cple days though, see a dr.
