Chiron Corp., Emeryville, Calif., said it received a grand jury subpoena from the U.S. attorney for the Southern District of New York requesting documents related to Chiron's Fluvirin influenza vaccine and the suspension of the company's manufacturing license for its Liverpool, England, plant.
Chiron officials said they intend to fully cooperate with the probe. The U.K. temporarily suspended Chiron's license last week, cutting the expected U.S. supply of flu vaccine by about half.
In other legal actions related to flu vaccine supply, the Kansas attorney general sued pharmaceutical distributor Meds-Stat, Fort Lauderdale, Fla., for alleged price-gouging. Meds-Stat allegedly proposed to deliver and sell a vial of five doses of flu vaccine to a Kansas City, Kan., pharmacy for $900, Attorney General Phill Kline said in a news release. The price for a vial of the same size was listed as $85 Oct. 1.
