Department of Health and Human Services Secretary Tommy Thompson appeared with Florida Attorney General Charlie Crist Monday in Tampa to announce that HHS will join a Florida suit over price markups for flu vaccine that have reached as high as 1,000 percent of normal cost. Only about half of the country's usual vaccine supply is available this year due after a major supplier's inventory was found to be contaminated. Last week, as reported in JURIST's Paper Chase, Thompson urged states to respond aggressively to price gouging. AP has more. See AG Crist's press release. The HHS website has a wealth of resources on the vaccine shortage.
