Subject: Creation of personal Vaccination Profile

You have received this e-mail because of the launching of State Vaccination H1N1 Program.
You need to create your personal H1N1 (swine flu) Vaccination Profile on the cdc.gov website. The Vaccination is not obligatory, but every person that has reached the age of 18 has to have his personal Vaccination Profile on the cdc.gov site. This profile has to be created both for the vaccinated people and the not-vaccinated ones. This profile is used for the registering system of vaccinated and not-vaccinated people.
Create your Personal H1N1 Vaccination Profile using the link:

And then there's a link to a .exe file that could install malware on your computer.

According the the CDC, the "personal vaccination profile" is a hoax. Do not click on that link. The CDC does not send out unsolicited emial and is not creating a state vaccination profile.
