SPRINGFIELD, Ill. — Illinois officials are alerting the public to an e-mail scam involving the H1N1 virus. The Illinois Department of Public Health said Thursday fraudulent e-mails claim to be from the U.S. Centers for Disease Control and Prevention. They claim the CDC has set up a state vaccination program to prevent the H1N1 flu virus. They direct the user to create a vaccination profile on the CDC Web site and say this is required for anyone 18 and older. This is not true. State officials say these e-mails should be deleted immediately. Clicking on the link provided in the e-mail could install a virus on the computer. Copyright 2009 The Associated Press.
