Since 1990, the U.S. government has collected many thousands of reports of damage caused by vaccines. This database, called the Vaccine Adverse Event Reporting System (VAERS), is available for anyone to download. However, the data available from the government is difficult to use for these reasons:

• It is broken up into separate databases for each year.
• Each year's data is split into two different files: one with the details of the case, and another with specific information about the vaccinations that were given.
• The data is in raw form, and must be imported into a real database system before any analysis can be done.
• There are some formatting errors in these files.

The site organizes the government's VAERS data and makes it available for online searching. Before using this data, please read the government's warning about the data.

This data covers the period of time from the start of the program in 1990 to September 30, 2002.
