USA - Healthcare - Flu Vaccine... Doses of a flu vaccine lie on a table as San Luis Obispo County public healthcare professionals conduct a mass flu vaccination drill at the Veterans building in San Luis Obispo, California. The drill was to administer up to 1,500 free doses of this season's flu vaccine to a large number of people, as well as to test the readiness of the county to handle an outbreak of a serious communicable disease such as the Avian "Bird" Flu.
