Failure to Pass Zika Funding Already Hurting Research

Public health researchers say Congress' failure Thursday to pass funding to fight the Zika virus will hurt efforts to fight it, including stalling research into a potential vaccine and how the virus causes birth defects. Scientists had already warned that the $1 billion in proposed spending was coming too late. More than 1,300 people in the U.S. already have the virus. The disease is spreading rapidly in Puerto Rico, an American territory.
