New flu medicine

Japanese pharmacy company Shionogi announced an new anti flu drug that cures all types of flu in 24 hours, with a single dose.  The Wall St Journal didn't mention a name for Shionogi's experimental drug but it is not a vaccine, it works by disrupting the flu virus' ability to take over human cells and reprogram them to produce more flu virus.  The article indicated a deep understanding of the biochemistry of the flu virus.  It also mentioned a fast track approval process in Japan might authorize the drug for sale as soon as next month.  They talked about submitting paperwork to the US Fuddy Duddy Administration (FDA) this summer and waiting til next year for FDA approval for sale in the US. 
   If this works out, it will be great.
