Nascar Rash...

The House Homeland Security Committee planned a fact-finding trip about public health preparedness at mass gatherings and decided to conduct the research at two of the nation's most heavily attended sporting events, NASCAR's Bank of America 500 event this weekend and the UAW-Ford 500 last weekend.

Staff who organized the trips advised the NASCAR-bound aides to get a range of vaccines before attending -- hepatitis A, hepatitis B, tetanus, diphtheria and influenza.
