Health officials are warning the public about fake e-mails inviting people to sign up for swine flu vaccine registrations.
U.S. Centers for Disease Control and Prevention officials this week put out an advisory about the e-mails, which call for adults to create a personal H1N1 (swine flu) vaccination profile on the cdc.gov Web site.
CDC officials say the e-mails appear to be spam messages designed by hackers to spread a computer virus.
The CDC does not have such a vaccination program.
