The United States fumbled its response to the Ebola epidemic before it even began, neglecting experiments to make vaccines and drugs against the virus, and cutting funding to key public health agencies, a presidential commission said Thursday. Americans focused on their own almost nonexistent risk of catching Ebola from travelers instead of pressing to help the truly affected nations, the scathing report from the Presidential Commission for the Study of Bioethical Issues says. They've been acting against their own best interest, the commission said in its report. Ebola started spreading in Guinea just about a year ago, but the response was slow.
