Flu experts are predicting the flu season will hit early and hard, with a resurgence of the H1N1 swine flu virus this fall.  News 2 talks with infectious disease expert Dr. William Schaffner of Vanderbilt.  He says there will be two kinds of flu vaccine.  One for regular flu, and another for H1N1.  160 million doses will be available later in the fall, and it will likely require two shots, one month apart.  Dr. Schaffner is also recommending everyone have a Swine Flu Survival Kit.
