I just got a flu shot today. As self employed musicians, most of us don't have the benefit of 'paid sick leave', so really can't afford canceling those eseential high paying Christmas/New Years holiday gigs due to illness. To act as an insurance preventative, I routinely get a flu shot (every year) which (so far) has successfully kept me from coming down with the flu, and which can keep you out of commission for up to 2 weeks. The only downside is that flu shots don't protect againest the common cold. - Scott
