A key Senate committee on Wednesday advanced legislation that would help the U.S. prevent and respond to pandemics, just as deaths from Ebola are rising overseas.

Sen. Rand Paul, R-Ky., was the only senator on the Health, Education, Labor and Pensions Committee who did not support the measure, which would reauthorize the Pandemic and All Hazards Preparedness Act, or PAHPA. The bill must be reauthorized by September or programs under PAHPA will expire.
