2008
Fluvirin-related shareholder litigation settlement
A class action alleged that Chiron and company executives had overstated the company's ability to manufacture and ship Fluvirin before the Liverpool plant shutdown. The litigation was settled in 2008 for $30 million.
2004
Fluvirin contamination and manufacturing-license suspension
The UK regulator suspended Chiron's license to manufacture Fluvirin at its Liverpool plant after contamination concerns, including reports that millions of doses might have been affected by Serratia marcescens. The action contributed to an influenza-vaccine shortage in the United States and led to remediation, regulatory scrutiny, and shareholder litigation.
