Had a flu shot this year. Have thus far managed to escape the two rounds of plague that have made smashed their way through my office and OCBF's office. Have gotten a bit sniffly and sort of phlegmy but never true sick. I take a supplement of echinacea and goldenseal for a week every month however, so that helps too. That and, as Brewtus said, I drink a lot. It keeps the bacterias to soused to really do their jobs right, little slackers.
